Abstract

Sharing of resources is a common feature of human societies. Yet, there is substantial societal variation in children’s generosity, and this variation emerges during middle childhood. Societal differences in self-construal orientation may be one factor influencing the ontogeny of generosity. Here, we examine anonymous Dictator Game sharing in 7-and-8-year-olds from two distinct societies: India and the UK (N = 180). We used self-construal manipulations to investigate whether priming self- or other-focused conversations would differentially influence children’s generosity. There were no differences in generosity between populations. While a significant reduction in generosity was found following self-priming in both societies, other-priming was ineffectual. The findings are discussed in relation to experimental features and the role of anonymity and reputational concerns.

Introduction

Most people share resources with others, but to varying degrees across societies and ages (e.g., [13]). Developmentally, there appears to be a consistent pattern where young children initially show a bias towards not sharing with others, but are increasingly more likely to share and to share more resources as they get older [47]. For example, when asked to share resources with other non-related individuals, pre-schoolers typically self-maximize [2, 3, 8, 9]. However, from middle childhood (7–8 years), children become sensitive to normative information about costly sharing and increasingly conform to their society’s generosity norms [3, 4, 5, 9].

Whether we share or not has been linked to the way that we think about our self. Indeed, being “selfish” is a common definition of not sharing. Self-construal can be defined as the collection of thoughts, feelings and actions concerning the self as separate from others, and the self in connection with others [10]. Consequently, one typically separates between independent and interdependent construals of self [11]. It should, however, be noted that independent and interdependent self-construals coexist in all individuals, but can be emphasised and accessed to varying degrees [10]. Research on the link between self-construal and generosity in children dates back at least 40 years. For example, when 7- to 12-year-olds were asked to recall happy, sad or neutral events experienced by themselves or with another child, those who recalled sad events involving another, subsequently shared more than those who recalled sad personal events [12]. More recently, studies of pre-schoolers’ understanding of the emotional consequences of sharing for themselves versus another recipient child, show that they readily understand the positive emotional benefits of sharing for themselves [13]. Moreover, when pre-schoolers are induced to share in one situation, they become increasingly generous in subsequent sharing situations [14]. This work indicates that that from preschool years and onwards, children are both aware of the personal emotional benefits of sharing and can be induced to be more generous. However, one caveat is that these experimental manipulations often involve public displays of generosity. For example, in the three studies mentioned above [1214], sharing was carried out in view of an experimenter. Both adults and children behave more generously when others witness their actions (e.g., [1522]) which suggests that reputational effects should be taken into consideration when considering the development of generosity.

Societal variation in children’s prosociality is often linked to differing socialization goals and practices (e.g., [2326]). For example, Western middle-class families emphasise autonomy and individuality in their child rearing, arguably leading children to develop more independent self-construals [2633]. Conversely, other societies promote connectedness and group affiliation, arguably fostering more interdependent self-construals [2628, 3336]. Thus, while any individual’s self-construal includes both self- and other-focused elements, their relative accessibility and salience varies between societies [33, 37] and may play a role in shaping prosocial behaviours.

A good way to test the impact of self-construal orientation on generosity is to experimentally manipulate it. Recent studies have begun to investigate subtle ways of priming self- and other-focus to influence generosity in sharing [38, 39]. In one study by Weltzien et al. [39], British and Indian children took part in semi-structured interviews where they were asked to talk about themselves (self-focus), friends and family (other-focus), or animals (control condition). Following this simple manipulation, the children completed a forced-choice sharing game. Across 12 trials, the children decided between two mutually exclusive options for distributing tokens to the self and to “another child”. The tokens would later be exchanged for stickers. It was found that children from both the UK and India became less generous following self-focus. However, following other-focus, only Indian children from traditional extended families increased generosity. No prosocial effect from other-focus was observed in the British sample [39]. This is an interesting finding, which could suggest that sociocultural differences in the prominence of independent and interdependent self-construals may influence the ease with which children are swayed towards generosity or selfishness. In other words, stronger interdependent self-construals in the Indian participants may have rendered them more susceptible to the prime, resulting in a genuine drive towards generosity.

However, research on the effects of self-construal manipulations on generosity in different sociocultural settings is still in its infancy. In the present experiment, we therefore sought to further explore the effects of self and other focus on children’s sharing using the same priming manipulation as Weltzien et al. [39], but a different sharing paradigm which offers a wider range of sharing responses than the forced-choice sharing paradigm and can be easily implemented as an anonymous sharing task; namely the Dictator Game. In the Dictator Game, participants are endowed with a number of items and informed that they can keep all, or share some with a recipient [40]. Any sharing thus entails a cost to the participant. The simplicity of the Dictator Game paradigm has made it a popular tool for examining sharing-decisions across ages and societies and is usually, but not always, implemented as an anonymous task (e.g., [3, 8, 9, 4143]). Moreover, as the Dictator Game is one-shot, there is no chance of reciprocity from the recipient, and, unlike the forced-choice sharing paradigm which is conducted in full view, anonymity can easily be controlled [8]. The Dictator Game is therefore by many considered ideal for systematically assessing sharing behaviour as it allows experimenters to minimise social influences.

The current study explored sharing behaviour in British and Indian seven- and eight-year-olds by adopting the priming paradigm developed by Weltzien et al [39] for a new task and sample of children. Across societies, middle childhood (seven-eight years) has been identified as an important phase in prosocial development where self-interested behaviour is diminished, and children begin to adhere to the prosocial norms of their society [3, 4, 9]. Similarly, middle childhood represents an important phase in the development of reputational concerns. Young children do not appear to adjust their prosocial behaviours in ways that improve their reputation. However, by middle childhood children begin to reason explicitly about their reputation and, at this age, a concern for own reputation has been shown to guide aspects of children’s prosocial acts, such as sharing and fairness [44].

The United Kingdom and India are two societies that have traditionally been characterised as more individualistic and collectivist respectively [4547], with corresponding higher rates of generosity and fairness found in more collectivist societies, compared to more individualistic societies (e.g., [23, 25, 38, 39, 48, 49]). Based on previous findings [38, 39], we predicted that self-focus would decrease donations in both British and Indian children. Further, if the societal differences in self-construal orientation between our two populations render Indian participants more receptive to the other-focus prime, we would expect to see an increase in donations from the Indian children, but not the British children, following other-focus compared to the control (i.e. we would see an interaction between prime type and society). Finally, in a separate, exploratory analysis we investigated whether family structure (extended vs. nuclear) would influence Indian children’s sharing decisions in the three conditions (see Weltzien et al [39] for similar analyses). Traditional Indian families typically harbour three or more generations, including members of the extended family. In such families, “collective responsibility” is often highly valued, with the needs of the family superseding the needs of the individual. Children from extended families, as opposed to Western-style nuclear families, may thus have more salient interdependent self-construals and may therefore be more susceptible to the interdependence manipulation (i.e. we tested for an interaction between prime type and family structure in the Indian sample only).

Method

Participants

The Indian sample included 90 seven- and eight-year-olds enrolled in a middle- to upper-class private school in Pune (Mage = 94.53 months, SDage = 6.11, range = 84–106 months; 47 females). The British sample included 90 seven- and eight-year-olds enrolled in middle- to upper-class schools in Bristol (Mage = 94.16 months, SDage = 7.24, range = 84–107 months; 48 females). Pune is a large-sized urban city in the West of India, with an estimated population of 4 million residents. Main industries include IT and manufacturing. Bristol is a medium-sized urban city in the South-West of England, with an estimated population of 460,000 people. Main employing industries include Retail and Health and Social Care. The city is diverse with 22% non-white British residents. The sample size was specified a priori in keeping with previous research using a similar method and design [39]. An additional six Indian children and one British child took part but were subsequently excluded from analysis because they failed to pass one or more of the control questions. Indian children completed all of their lessons in English and had a high level of English language proficiency. Testing was therefore conducted in English by the 1st and 2nd authors in both societies. Participants were tested individually in quiet rooms in their respective schools. Informed consent was provided in writing by all parents, and verbal agreement was obtained from all children who participated in the study.

Procedure

Prior to data collection, the protocol and procedures of this study were approved by the University of Bristol Faculty of Science Human Research Ethics Committee (ethics approval code: 28041636381). Data was collected in Pune in August and September 2016, and in Bristol in March to July 2017.

Sticker allocation

Each child was given a selection of ten animal stickers and informed that s/he could select six of them to keep. Once the selection was made, the remaining stickers were removed from sight. The child’s selected stickers remained in view, but out of reach on the table.

Priming-procedure

Adopting the priming-procedure of Weltzien et al [39], each child took part in one of three conditions (between-subjects design): self-focus, other-focus or a control condition. The priming tasks were designed as semi-structured interviews. Questions asked during self- and other-focus interviews were constructed from the list of independent and interdependent self-construal primes by Kühnen and Hannover [50].

In the self-priming condition, the experimenter asked a series of questions about the child aimed to prime notions of self (e.g., “what makes you special?” or “how are you different from other people?”). In the other-priming condition, the experimenter asked questions about the child’s relationships with significant others to prime notions of relatedness (e.g., “is there anyone in your life that you feel close to?” or “why is it important to have good friends?”). In the control condition (baseline sharing), the experimenter asked questions about animals, and personal pronouns were carefully avoided. For full priming scripts and experimental instructions, see supporting information (S1 File).

Dictator game

Two envelopes were introduced to the child. One envelope belonged to the child and it was explained that everything put into this envelope could be taken home. The other envelope belonged to “another, unknown child from a different school”. The participating child was then told that he or she could give away some of the stickers to this other child, but that he or she did not have to give any stickers away. It was further explained that if he or she wished to give away any stickers, then these could be placed into the “other child’s” envelope before posting it into a box. The experimenter turned away during the sharing task so that sharing decisions remained fully anonymous. Control questions were included to ensure that children understood the task. Data from seven children (6 Indian, 1 British) who failed either of the control questions were excluded from analysis.

Data coding and analysis

All statistical analyses were performed using SPSS statistical software version 23.0. The number of stickers shared was converted to a percentage for each child. Child age in months at the date of testing was calculated and included as a variable in all analyses. This was done to control for any potential variance associated with age within the sample. Preliminary analyses indicated no effects of gender in any of our analyses so this factor was not considered further. Two dependent measures were calculated from the sharing data. 1) The number of children deciding to share in each priming-condition (i.e. sharing nothing vs. sharing one or more stickers) was analysed using a logistic regression with society, condition and their two-way interaction as well as age as predictors. 2) The percentage of stickers shared was analysed with an ANCOVA, followed by Bonferroni-adjusted comparisons. Prime type and society and their two-way interaction were entered as between subject factors, and age in months was entered as a covariate. All summary statistics are presented in Table 1, and the raw data file is available as supporting information (S2 File). Finally, following from Weltzien et al [39], a separate analysis was conducted to explore the effect of family structure on sharing behaviour in the Indian population. The analytical procedure was identical to the procedure described above. However, instead of including culture as a predictor (logistic regression) and between subjects’ factor (ANCOVA), the current analysis included family structure (extended vs. nuclear).

Prime Type Society N Decision to share % Shared [95%CI]
Self India 30 16 14.99 [9.03, 20.97]
UK 30 24 23.33 [17.31, 29.36]

UK 30 27 30.56 [24.00, 37.11]
Neutral India 30 28 31.67 [25.48, 37.86]
UK 30 28 35.55 [29.72, 41.39]

Average time spent on the priming interviews did not differ significantly across societies, F(1, 178) = 1.78, p = .18, ηp2 = .006. Moreover, interview times did not differ significantly across conditions in the Indian population, F(2, 87) = .91, p = .41, ηp2 = .02, nor in the British population, F(2, 87) = .37, p = .69, ηp2 = .008. Therefore, this factor will not be considered further. Summary statistics of all priming time data is available as supportive information (S3 File).

Results

Decision to share

A test of the full model against a model containing only the intercept was statistically significant, indicating that the predictors together reliably distinguished between sharing and not sharing, X2(6) = 23.61, p < .001. The results revealed a trending reduction in willingness to share following self-priming compared to the control (β = -3.54, p = .058). There was no significant difference in decision to share between other-priming and the control (β = -.39, p = .854). Finally, society was not a significant predictor of sharing decision (β = -.66, p = .133), and there was no significant interaction between society and priming condition (p = .448). Nevertheless, an inspection of the frequency distribution of donations in each population revealed that the number of zero-sharers (children choosing not to share) was more than twice as high in the Indian population compared to the British population following self-priming (see Fig 1). Moreover, only in the British population did we see examples of sharing exceeding the fairness-principle (i.e., sharing more than half of the endowment).

Percentage of stickers

On average, Indian children shared a smaller percentage of their stickers (MIndia = 25.74%, 95% CIIndia = [21.99, 29.48]) compared to British children (MUK = 29.81%, 95% CIUK = [26.25, 33.38]), but this difference was not significant, F(1, 173) = 2.77, p = .098, ηp2 = .02. No significant interaction was found between priming condition and society, F(2, 173) = .966, p = .383, ηp2 = .011. Priming condition had a significant effect on percentage of stickers shared, F(2, 173) = 12.86, p < .001, ηp2 = .13 (see Fig 2). Across both societies, children shared significantly fewer stickers following self-priming (Mself = 19.17%, 95% CIself = [14.91, 23.42]), compared to the control (Mneutral = 33.61%, 95% CIneutral = [29.45, 37.77]), t(118) = -4.86, p< .001, d = 0.89 (Bonferroni corrected), and to other-priming (Mother = 30.56%, 95% CIother = [26.20, 34.91]), t(118) = -3.74, p < .001, d = 0.68 (Bonferroni corrected). There was no significant difference in the percentage of stickers shared following other-priming compared to the control, t(118) = -1.02, p = .312, d = 0.19.

Family structure data, Indian sample

Of the current participants, 48 children lived in traditional extended families, whereas 42 lived in nuclear families. Family structure (extended vs. nuclear) was not a significant predictor of decision to share (β = .85, p = .110). Moreover, there was no effect of family structure on percentage of stickers shared, F(1, 83) = 1.05, p = .309, ηp2 = .012, and no interaction between family structure and condition, F(2, 83) = .03, p = .970, ηp2 = .001.

Discussion

In the current study, we explored the effects of self- and other-focus on British and Indian children’s generosity in a simple Dictator Game. We did not measure existing self-construals in this study, but were interested in how children would react to priming that focused on self or relatedness to others. In both societies, focusing on oneself reduced donations compared to a control condition. This is in keeping with evidence of reductions in sharing, trading and helping following self-focus [38, 51]. Moreover, this finding is consistent with previous cross-societal evidence [39] and extends this research to a different sharing paradigm that allows for more nuanced responses. However, other-focus was ineffectual across both groups. Consequently, the present results diverge from the findings of Weltzien et al [39], who revealed increased generosity following identical other-focus in Indian participants from extended families. What could explain these diverging outcomes?

In experimental settings, subtle methodological variations can substantially influence sharing decisions (e.g., [18, 52, 53]). For example, it is well documented that donations in sharing games vary as a function of anonymity. Indeed, both adults and children behave more generously when others witness their actions (e.g., [1521]) which suggests that reputational effects should be taken into consideration when considering the development of generosity, particularly in middle childhood. Anonymity may be particularly important in cross-societal comparisons of sharing behaviour as reputational concerns and the perceived role and status of the experimenter may differ vastly between societies (e.g., [1, 54]).

The vast majority of previous cross-cultural sharing studies have used tasks taking place in view of the experimenter (e.g., [3, 4, 5, 24, 39, 48, 49, 55]). Thus, while participants often share with an anonymous receiver, the sharing typically takes place in front of a non-anonymous, adult experimenter, and herein lies a potential problem. Whereas the receiver is oblivious to the participants’ decision, the experimenter is not. Sharing decisions may therefore reflect culture-specific concerns and expectations regarding the experimenter, rather than simply being a function of social preferences [1]. While participants in the study by Weltzien et al [39] shared with an unidentified other child, the sharing allocations took place in full view of the experimenter. Participants may not be indifferent to the experimenter’s impression of their decisions. For example, participants may be concerned with appearing greedy, or wish to promote a reputation of being generous. It seems plausible that these concerns are stronger in societies that promote and emphasize the value of interdependence. The presence of the experimenter may therefore have influenced both sharing decisions overall, and the effects of the priming in the Indian population. For example, other-focus may have boosted reputational concerns in the Indian participants by triggering an awareness of the experimenter’s presence. Note that due to the use of different sharing paradigms, it cannot be strictly determined whether differences in findings between Weltzien et al [39] and the current study are due to reputational concerns or methodological differences. Future studies could investigate this issue by replicating the current paradigm and comparing sharing behaviour in the experimenter’s presence and absence, respectively.

A further possible reason for not detecting an influence of the other-focus primes may be that there is a mismatch between the people being discussed in the other-focused interview and the potential benefactor in the Dictator Game. During self-priming, the person being discussed is the child themselves and later in the dictator game, they are themselves the beneficiary of selfish decisions. The other-focused interview, however, centres on people familiar to the child (e.g., friends and family), yet the potential benefactor is someone different—an unknown child. Future studies should therefore explore whether findings will differ if the benefactor of the Dictator Game is one of the people that the participants were prompted to think about during other-priming. The instructions in our current and previous cross-cultural studies [39] to share with an anonymous child from another school, may also undermine the willingness of children to share with someone who is potentially regarded as an outgroup member [2]. This would not explain the differences we found between the studies, but it does offer another potential line of cross-cultural investigation to examine how in-group/out-group categories affect children’s willingness to share. Finally, it is also possible that self-priming task could lead the children to view the self in a positive way. Indeed, several of the questions in the self-focus interview were of a positive nature, such as “what are you good at?” and “what makes you special?”. Thus, in addition to self- focus, the self-priming interview may have primed a distinctly positive view of the self that could have made participants feel entitled to more resources. Whilst this interpretation does not refute the main finding that self-priming significantly reduces sharing, it could provide an alternative account of how self-priming operates.

In our current study, we find that Indian and British children share 31.67% and 35.55% respectively in the control condition. In adults, the DG is subject to cross-cultural variation with varying levels of generosity typically falling somewhere between 20% and 30% of the original stake (see [40, 56] for reviews). In the available studies of children, however, there is more scope for variation. This may be because adult studies have typically used cash, whereas developmental studies have used a range of age-appropriate resources which may be difficult to match across different groups. For example, stickers are appropriate for younger children, but less so for older children. In one study by Harbaugh, Krause, and Liday [57], seven-, nine-, 10-, 14-, 18-year-olds completed a variety of economic games, including the DG. It was found that the older groups, on average, offered between 10% and 20% of their resources, whereas the seven-year-olds offered less than 10%. This is thus a lower rate of sharing than observed in our current study. However, Gummerum et al., [41] found that children as young as five years of age shared 43% of their stake on average, and Benenson et al. [8] found that four-year-olds, on average, donated between 20% and 30% of their endowment, while six- and nine-year-olds gave slightly more.

The UK and India are two societies that are often characterised as more collectivist and individualistic respectively [45] with corresponding higher rates of generosity and fairness found in more collectivist societies, compared to more individualistic societies (e.g., [23, 24, 48, 49]. However, it is increasingly recognised that the individualism/collectivism dichotomy is overly simplistic and, in some ways, both empirically and theoretically limiting (e.g., [58]), and we did not find this pattern in our sample of children from these two societies. Instead, the current findings fall into the line of recent empirical studies that demand a more refined outlook on societal differences in children’s prosociality. For example, exploring the sharing behaviour of 5- to 12-year-olds from five diverse societies, Cowell et al [9] found higher rates of generosity in children from more individualistic societies (The US and Canada), compared to children from China, Turkey and South Africa. Further research revealed an aversion to receiving more than others (advantageous inequity aversion) from 7–8 years of age in children from the U.S., Canada, and Uganda, but not in children from Mexico, Senegal, rural Peru or rural India [55]. Thus, the rejection of a relative self-advantage was not apparent in a majority of the non-Western populations. We suggest that societal variations in reputational concerns and subtle methodological differences could play a critical role in the divergent outcomes that have emerged from cross-societal studies of children’s sharing behaviour. A careful re-examination of previous cross-societal studies from the reputation perspective using consistent, anonymous methodologies may therefore be required to disentangle the relationship between reputation and developing prosociality.

While the impact of self- and other-focus on British and Indian children’s generosity was the focus of the current study, there are other socioecological differences between the two societies that could influence the results. One such difference is the relative affluence of the two societies. In both India and the UK, we sampled from schools that were mostly attended by children from middle to upper class families. While this ensured that social class was similar within the respective countries, children from UK families may have nevertheless been more affluent when comparing absolute household income. Objective income [8] but also subjective SES may have a different impact on children’s resource distributions and their judgements about distributions [59]. However, in the current study, we found no significant differences in generosity between Indian and British participants.

In conclusion, the current findings provide further evidence that self-focus increases children’s selfishness in two distinct societies. Yet, other-focus was ineffectual. While it is remarkable that children across societies can so easily be moved toward greater selfishness, the difficulty in moving them toward greater generosity is equally noteworthy. We speculate that differences in reputational concerns may explain some of the divergent outcomes that have emerged from cross-societal studies of children’s sharing behaviour.

Reviewer #1: This manuscript presents the results of a study on how self-construal priming affects children’s generosity in India and the UK. Self-priming was found to reduce sharing relative to no priming, while Other priming and no priming produced similar levels of sharing. These findings constituted a partial replication of prior work; they provide additional support for the claim that self-priming reduces sharing, while the effects of other priming appear to be more context-dependent and did not emerge in the current sample. In terms of the cross-cultural findings, results were mostly similar in India and the UK, although differences may have emerged with a slightly larger sample size.

Overall, I enjoyed this paper. I found it to be well-written and succinct, with useful summaries of prior work on this topic. I enjoyed the authors’ mention of the complexities of “individualistic vs. collectivist” distinction, which is too often presented in the literature as straightforward and unproblematic. The methods were clear and the results rather straightforward, nicely replicating past work on how self-priming affects children’s generosity. The overall contribution is not extremely novel in light of prior research (please note that I am aware that novelty per se is not emphasized for this particular review process), but it still helps advance the field in the terms of testing the boundary conditions of prior effects. While I do have several suggestions for improvement, my overall impression of this contribution is positive. My proposed changes are fairly straightforward and should be addressable in a revision. I have a general concern that the study is under-powered (and the lack of an a prior power analysis is a shortcoming) for examining certain effects (e.g., sample sizes for the Indian sample for the different family structures were quite small). That said, these concerns can easily be addressed via post-hoc sensitivity analyses and more discussion of how confidently we can interpret null findings as such. Additional data collection is not needed. I shall outline my suggestions in the next section of this review.

Page 2: “where young children initially show a bias towards not sharing with others, but are increasingly more likely to do so” – The authors’ focus is on whether children share or not, which makes the choice to share seem binary rather than continuous. The discussion of this topic would benefit from briefly noting that children also share more resources when they choose to share as they get older (i.e., the total amount shared increases with age), and not just that they are more likely to share as they get older.

Page 2, last paragraph: The second part of this paragraph focuses on preschoolers, but the age range of the present study does not include preschoolers (I view “preschoolers” as 5 years old or younger). The authors could briefly add a statement that presumably these effects are true of older children as well, to make these findings more directly relevant to the age range of the current study.

“However, one caveat is that these experimental manipulations often involve public displays of generosity.” – Particularly because the private/public distinction wound up being important in the current study, in this section and others, I would appreciate knowing which studies involved public versus private displays of generosity. Of references 10- 12, were all public? And for the Dictator Game studies that follow (when discussed later on in the paper), which involved public versus private donations?

It is worth noting that the study more or less assumes that children in the UK and India have different self-construal orientations, which seems plausible, but the orientations themselves are never directly tested. Could they be tested/are there methods to do so? This could be a topic for the Discussion.

Page 3: “subsequent forced-choice sharing paradigm” – can the authors share a bit more about this? Was it a “mini Dictator Game?” Just a few sentences of detail would be helpful so the readers can get a clearer sense of how methods diverged across studies (it is clear the the current study’s traditional DG is different, but different compared to what?).

Page 5:

A very brief (sentence or two) justification of the age range would be useful. (For instance, was it tied to the original Weltzien at al age range? What about reputation-based concerns for this age range?) I agree based on my knowledge of this literature that 7- and 8-year-olds are suitable, but it’s not entirely clear from the manuscript itself why they were chosen.

Sample size: It is a bit unfortunate that the sample size was set based solely on convention rather than after a power analysis. One solution would be to present results of sensitivity analyses or post-hoc power analyses in this section, e.g., given the relevant sample sizes, what effect sizes would be detected with 80% power? In other words, for the UK compared to India analyses, for instance: how large would the effect have to be to detect between-site differences, etc., given the sample sizes tested? The relevant analyses here are 1) self focus compared to control, in each location separately 2) a condition by site interaction (other focus is expected to boost sharing only in India) 3) nuclear vs. extended family, following other-focus, in India alone; my summary is based on the predictions mentioned on page 4. My overall sense is that the study makes an important contribution, and the self vs. control condition effects are compelling, but that the study is likely underpowered to detect effects 2) and 3) and that the results should be qualified in the Discussion accordingly. In other words, only with very strong effects would a significant interaction and a family-based analysis be detectable given the cell sizes (the cell sizes for 3) are particularly small). The null effects could be considered less as definitive nulls and more as open questions. Shortcomings surrounding the lack of prior power analyses, and limits of conclusions regarding null findings in light of sample size, should be address as limitations in the Discussion. For instance, “As noted, there were no significant differences in generosity between Indian and

British participants. However, we note that our sample size would have been insufficient to detect a small-to-medium effect of location … ” (for example, for modifying page 10)

Page 8: On Page 4, it seemed as though the authors predicted significant effects of self vs. control for each site individually (not just combined across site), but site-specific results are not reported. To make the results consistent with the predictions, I’d suggest reporting the results separately for India and the UK in addition to reporting combined analyses; although I recognize the lack of a significant interaction, I think the predictions are sufficient justification to present analyses for each site.

Page 9: The family structure results, as currently reported, do not quite align with the predictions. In addition to the analyses already presented, please show results for the other condition only, comparing extended vs. nuclear family results (“we predicted higher levels of generosity in Indian children from extended families compared to Indian children from nuclear families following other-focus.”)

Page 9 – The manuscript notes, “reputational effects should be taken into consideration when considering the development of generosity.” There is a missing part of the developmental story here; that concern with reputation is minimal in early childhood but should be operative within the age range of the study. Engelmann & Rapp, 2018, provides a review; some discussion of reputational concerns as changing with development would be useful.

Discussion: One limitation of the general experimental approach is that the self- and other-focus interview questions are not very closely equated. In other words, it’s not the case that the same questions are asked but regarding different targets (for example, “can you think of a time when something good happened to you?” compared to “can you think of a time when something good happened to a friend?”); instead, the content of the questions themselves is quite different, and not just the targets. For instance, “what makes you special?” which is posed in the self-focus interview, has no analog in the other-focus interview. It seems as though the self-focus condition might not just prime a self focus but cause one to view the self in a positive way specifically, while the same is not true of the other-focus condition regarding others. To be clear, I do not think this issue is mostly responsible for the self-focus condition differences, but it should be mentioned as a limitation: namely, that addition to priming self-focus, the self-focus condition may have also primed a distinctly positive view of the self that could have made participants feel entitled to more resources.

Discussion: The role of SES/family income warrants some space in the Discussion. I appreciate the characterization of both schools as “middle- to upper-class,” but due to differences in standard of living in the two countries, the UK school was likely more affluent. There is some work suggesting that family income in and of itself could affect children’s Dictator Game sharing (e.g., Benenson et al), although the direction of the effect is disputed. A brief mention that affluence, in addition to the favored discussion of specifically cultural factors, could have affected the results would create a more complete picture of the relevant issues for the readers.

Readers might be curious as to how the rates of sharing in the current study compare to those of other studies with similar methods and ages; are there any that can be summarized briefly in the Discussion?

Page 11- typo: “For example, Moreover,”

Reviewer #2: 1. I’m a bit curious about the link between the Weltzien et al. (2019) paper and the current study. Was this aimed to be more of a follow-up to that study to see if those patterns would extend to the Dictator Game? Is this an entirely new sample collected at a different date? Some of my additional comments / suggestions are contingent upon knowing the answer to this question.

2. Was there an a priori decision to make the allocation task private (e.g. have the experimenter turn around) and a prediction that this would influence sharing? Again, I think the history and provenance of this study versus the Weltzien (2019) study and the a priori motivations would be helpful for providing context & highlighting the unique contributions of this study.

3. Was there any sort of manipulation check, either in this study or a previous study, to ensure that the primes had the intended effects?

4. It would be helpful to have a clear definition of “self-construal orientation” or some explanation of what it is in both the abstract and in the introduction.

5. I would replace references to “universal patterns” with something like “regularities”.

6. Figure captions should include an explanation of what the error bars represent (e.g. standard deviation, standard errors, etc.)

The overall contribution is not extremely novel in light of prior research (please note that I am aware that novelty per se is not emphasized for this particular review process), but it still helps advance the field in the terms of testing the boundary conditions of prior effects. While I do have several suggestions for improvement, my overall impression of this contribution is positive. My proposed changes are fairly straightforward and should be addressable in a revision. I have a general concern that the study is under-powered (and the lack of an a prior power analysis is a shortcoming) for examining certain effects (e.g., sample sizes for the Indian sample for the different family structures were quite small). That said, these concerns can easily be addressed via post-hoc sensitivity analyses and more discussion of how confidently we can interpret null findings as such. Additional data collection is not needed. I shall outline my suggestions in the next section of this review.

Our Response: Thank you for your positive feedback and your suggestions.

Page 2: “where young children initially show a bias towards not sharing with others but are increasingly more likely to do so” – The authors’ focus is on whether children share or not, which makes the choice to share seem binary rather than continuous. The discussion of this topic would benefit from briefly noting that children also share more resources when they choose to share as they get older (i.e., the total amount shared increases with age), and not just that they are more likely to share as they get older.

Our Response: Thank you for this suggestion. We now mention the increase in total amount shared and reference a recent cross-societal study which found this increase across 12 countries. Specifically, we have reworded the sentence as follows:

“Developmentally, there appears to be a consistent pattern where young children initially show a bias towards not sharing with others, but are increasingly more likely to share and to share more resources as they get older [4-7].”

Page 2, last paragraph: The second part of this paragraph focuses on preschoolers, but the age range of the present study does not include preschoolers (I view “preschoolers” as 5 years old or younger). The authors could briefly add a statement that presumably these effects are true of older children as well, to make these findings more directly relevant to the age range of the current study.

Our response: Thank you for this comment. We have now amended the text to clarify this point. Specifically, we write:

“Moreover, when pre-schoolers are induced to share in one situation, they become increasingly generous in subsequent sharing situations [14]. This work indicates that from preschool years and onwards, children are both aware of the personal emotional benefits of sharing and can be induced to be more generous”.

“However, one caveat is that these experimental manipulations often involve public displays of generosity.” – Particularly because the private/public distinction wound up being important in the current study, in this section and others, I would appreciate knowing which studies involved public versus private displays of generosity. Of references 10- 12, were all public? And for the Dictator Game studies that follow (when discussed later on in the paper), which involved public versus private donations?

Our response: Yes, sharing in studies 10-12 (now 12-14) was indeed done in public (in view of an experimenter). We now specify this on page 3, where we write:

“However, one caveat is that these experimental manipulations often involve public displays of generosity. For example, in the three studies mentioned above [12-14], sharing was carried out in view of an experimenter".

For the dictator games studies cited later in the introduction (p. 4), some were done anonymously (e.g. references 8, 9, 49), for others it was not entirely clear from the methods whether sharing was done in view of the experimenter or not. We have reworded the sentences as follows:

“The simplicity of the Dictator Game paradigm has made it a popular tool for examining sharing-decisions across ages and societies and is usually, but not always, implemented as an anonymous task (e.g., [3, 8, 9, 41, 42, 43]).”

It is worth noting that the study more or less assumes that children in the UK and India have different self-construal orientations, which seems plausible, but the orientations themselves are never directly tested. Could they be tested/are there methods to do so? This could be a topic for the Discussion.

Our response: Thank you for this suggestion. We have added to the discussion that our study did not focus on existing self-construals but on the effect of priming self vs. others. We now write on p. 10:

“We did not measure existing self-construals in this study, but were interested in how children would react to priming that focused on self or relatedness to others.”

Page 3: “subsequent forced-choice sharing paradigm” – can the authors share a bit more about this? Was it a “mini Dictator Game?” Just a few sentences of detail would be helpful so the readers can get a clearer sense of how methods diverged across studies (it is clear the the current study’s traditional DG is different, but different compared to what?).

Our response: Thank you for this suggestion. We have now included a brief description of the forced-choice sharing game on p. 3. Specifically, we write:

“In one study by Weltzien et al. [39], British and Indian children took part in semi-structured interviews where they were asked to talk about themselves (self-focus), friends and family (other-focus), or animals (control condition). Following this simple manipulation, the children completed a forced-choice sharing game. Across 12 trials, the children decided between two mutually exclusive options for distributing tokens to the self and to “another child”. The tokens would later be exchanged for stickers. It was found that children from both the UK and India became less generous following self-focus. However, following other-focus, only Indian children from traditional extended families increased generosity”.

Page 5: A very brief (sentence or two) justification of the age range would be useful. (For instance, was it tied to the original Weltzien at al age range? What about reputation-based concerns for this age range?) I agree based on my knowledge of this literature that 7- and 8-year-olds are suitable, but it’s not entirely clear from the manuscript itself why they were chosen.

Our response: We agree that the article would benefit from a brief justification of the chosen age range. On page 4, we now write:

“Across societies, middle childhood (seven-eight years) has been identified as an important phase in prosocial development where self-interested behaviour is diminished, and children begin to adhere to the prosocial norms of their society [3, 4, 9]. Similarly, middle childhood represents an important phase in the development of reputational concerns. Young children do not appear to adjust their prosocial behaviours in ways that improve their reputation. However, by middle childhood children begin to reason explicitly about their reputation, and at this age, a concern for own reputation has been shown to guide aspects of children’s prosocial acts, such as sharing and fairness [44]”.

Sample size: It is a bit unfortunate that the sample size was set based solely on convention rather than after a power analysis. One solution would be to present results of sensitivity analyses or post-hoc power analyses in this section, e.g., given the relevant sample sizes, what effect sizes would be detected with 80% power? In other words, for the UK compared to India analyses, for instance: how large would the effect have to be to detect between-site differences, etc., given the sample sizes tested? The relevant analyses here are 1) self focus compared to control, in each location separately 2) a condition by site interaction (other focus is expected to boost sharing only in India) 3) nuclear vs. extended family, following other-focus, in India alone; my summary is based on the predictions mentioned on page 4. My overall sense is that the study makes an important contribution, and the self vs. control condition effects are compelling, but that the study is likely underpowered to detect effects 2) and 3) and that the results should be qualified in the Discussion accordingly. In other words, only with very strong effects would a significant interaction and a family-based analysis be detectable given the cell sizes (the cell sizes for 3) are particularly small). The null effects could be considered less as definitive nulls and more as open questions. Shortcomings surrounding the lack of prior power analyses, and limits of conclusions regarding null findings in light of sample size, should be address as limitations in the Discussion. For instance, “As noted, there were no significant differences in generosity between Indian and British participants. However, we note that our sample size would have been insufficient to detect a small-to-medium effect of location … ” (for example, for modifying page 10)

Our response: We did not carry out a priori power analyses. However, post-hoc power analyses based on observed power do not provide any additional information over the one already contained in the significance levels of our tests, as observed power is a 1:1 function of the p-value (see, Hoenig & Heisey, 2001, for a detailed explanation). Instead, one recommended approach is to report confidence intervals for all tests (e.g., Hoenig & Heisy, 2001; Yuan & Maxwell, 2005) which we do throughout the manuscript.

Page 8: On Page 4, it seemed as though the authors predicted significant effects of self vs. control for each site individually (not just combined across site), but site-specific results are not reported. To make the results consistent with the predictions, I’d suggest reporting the results separately for India and the UK in addition to reporting combined analyses; although I recognize the lack of a significant interaction, I think the predictions are sufficient justification to present analyses for each site.

Our response: The study was set up to test a 2x3 design and examine interactions between prime type and society. We have now clarified this in the introduction on p.5, where we write:

“Further, if the societal differences in self-construal orientation between our two populations render Indian participants more receptive to the other-focus prime, we would expect to see an increase in donations from the Indian children, but not the British children, following other-focus compared to the control (i.e. we would see an interaction between prime type and society).”

Page 9: The family structure results, as currently reported, do not quite align with the predictions. In addition to the analyses already presented, please show results for the other condition only, comparing extended vs. nuclear family results (“we predicted higher levels of generosity in Indian children from extended families compared to Indian children from nuclear families following other-focus.”)

Our response: Apologies, the wording in the introduction was not entirely clear. We have reworded the passage as follows:

“Finally, in a separate, exploratory analysis we investigated whether family structure (extended vs. nuclear) would influence Indian children’s sharing decisions in the three conditions (see Weltzien et al [39] for similar analyses). Traditional Indian families typically harbour three or more generations, including members of the extended family. In such families, “collective responsibility” is often highly valued, with the needs of the family superseding the needs of the individual. Children from extended families, as opposed to Western-style nuclear families, may thus have more salient interdependent self-construals and may therefore be more susceptible to the interdependence manipulation (i.e. we tested for an interaction between prime type and family structure in the Indian sample only).”

Page 9 – The manuscript notes, “reputational effects should be taken into consideration when considering the development of generosity.” There is a missing part of the developmental story here; that concern with reputation is minimal in early childhood but should be operative within the age range of the study. Engelmann & Rapp, 2018, provides a review; some discussion of reputational concerns as changing with development would be useful.

Our response: We agree with this point and thank the reviewer for the suggested reference. As described above, we now include a brief description of reputational concerns as changing with development on p. 4 in relation to the justification of the chosen age-range (see our earlier response for details). We have also slightly amended the sentence on p. 10:

“Indeed, both adults and children behave more generously when others witness their actions (e.g., [15-21]) which suggests that reputational effects should be taken into consideration when considering the development of generosity, particularly in middle childhood. “

Discussion:

1) One limitation of the general experimental approach is that the self- and other-focus interview questions are not very closely equated. In other words, it’s not the case that the same questions are asked but regarding different targets (for example, “can you think of a time when something good happened to you?” compared to “can you think of a time when something good happened to a friend?”); instead, the content of the questions themselves is quite different, and not just the targets. For instance, “what makes you special?” which is posed in the self-focus interview, has no analog in the other-focus interview.

Our response: It is indeed true that the self- and other-focus interview questions are not completely equated. We wished to adopt the priming procedure used in Weltzien et al [39], and therefore used exactly the same interview questions. This is stated on p 6. The priming questions were not matched perfectly because the other-condition aimed to prime interdependence, not simply a focus on someone else. Questions such as “what makes your friend special” were therefore not included, and instead the focus was placed on questions that would induce feelings of belonging and relatedness.

2) It seems as though the self-focus condition might not just prime a self focus but cause one to view the self in a positive way specifically, while the same is not true of the other-focus condition regarding others. To be clear, I do not think this issue is mostly responsible for the self-focus condition differences, but it should be mentioned as a limitation: namely, that addition to priming self-focus, the self-focus condition may have also primed a distinctly positive view of the self that could have made participants feel entitled to more resources.

Our response: Thank you for making this observation. We have now added the following paragraph to the Discussion on p. 11:

“Finally, it is also possible that self-priming task could lead the children to view the self in a positive way. Indeed, several of the questions in the self-focus interview were of a positive nature, such as “what are you good at?” and “what makes you special?”. Thus, in addition to self- focus, the self-priming interview may have primed a distinctly positive view of the self that could have made participants feel entitled to more resources. Whilst this interpretation does not refute the main finding that self-priming significantly reduces sharing, it could provide an alternative account of how self-priming operates.”

Discussion: The role of SES/family income warrants some space in the Discussion. I appreciate the characterization of both schools as “middle- to upper-class,” but due to differences in standard of living in the two countries, the UK school was likely more affluent. There is some work suggesting that family income in and of itself could affect children’s Dictator Game sharing (e.g., Benenson et al), although the direction of the effect is disputed. A brief mention that affluence, in addition to the favored discussion of specifically cultural factors, could have affected the results would create a more complete picture of the relevant issues for the readers.

Our response: We agree that the potential influence of differences in affluence between the testing sites warrants space in the discussion, and have now added the following paragraph on p. 13:

“While the impact of self- and other-focus on British and Indian children’s generosity was the focus of the current study, there are other socioecological differences between the two societies that could influence the results. One such difference is the relative affluence of the two societies. In both India and the UK, we sampled from schools that were mostly attended by children from middle to upper class families. While this ensured that social class was similar within the respective countries, children from UK families may have nevertheless been more affluent when comparing absolute household income. Objective income [8] but also subjective SES may have a different impact on children's resource distributions and their judgements about distributions [59]. However, in the current study we found no significant differences in generosity between Indian and British participants.

Readers might be curious as to how the rates of sharing in the current study compare to those of other studies with similar methods and ages; are there any that can be summarized briefly in the Discussion?

Our response: Thank you for this suggestion. We now provide a brief summary on page 12 of the discussion:

“In our current study, we find that Indian and British children share 31.67% and 35.55% respectively in the control condition. In adults, the DG is subject to cross-cultural variation with varying levels of generosity typically falling somewhere between 20% and 30% of the original stake (see [40, 56] for reviews). In the available studies of children, however, there is more scope for variation. This may be because adult studies have typically used cash, whereas developmental studies have used a range of age-appropriate resources which may be difficult to match across different groups. For example, stickers are appropriate for younger children, but less so for older children. In one study by Harbaugh, Krause, and Liday [57], seven-, nine-, 10-, 14-, 18-year-olds completed a variety of economic games, including the DG. It was found that the older groups, on average, offered between 10% and 20% of their resources, whereas the seven-year-olds offered less than 10%. This is thus a lower rate of sharing than observed in our current study. However, Gummerum et al., [41] found that children as young as five years of age shared 43% of their stake on average, and Benenson et al. [8] found that four-year-olds, on average, donated between 20% and 30% of their endowment, while six- and nine-year-olds gave slightly more.

Our response: Thank you for pointing out this mistake. It has now been corrected.

--------------------------------------------------------------------------------------------------

Reviewer 2:

1. I’m a bit curious about the link between the Weltzien et al. (2019) paper and the current study. Was this aimed to be more of a follow-up to that study to see if those patterns would extend to the Dictator Game? Is this an entirely new sample collected at a different date? Some of my additional comments / suggestions are contingent upon knowing the answer to this question.

Our response: The current study was indeed a follow up to the Weltzien et al. (2019) study to explore the effects of the same priming manipulation on sharing in a different sharing game (the Dictator Game). This is explained on page 4, where we now further specify that the current study used the same priming manipulation as Weltzien et al. (2019), but a different sharing paradigm. Specifically, we write:

“In the present experiment, we therefore sought to further explore the effects of self and other focus on children’s sharing using the same priming manipulation as Weltzien et al. [39], but a different sharing paradigm which offers full anonymity and a wider range of sharing responses than the forced-choice sharing paradigm; namely the Dictator Game”.

The current study did indeed test an entirely new sample. The data for the two studies were collected close in time, but at different dates. We have now clarified this in the introduction on page 4:

“The current study explored sharing behaviour in British and Indian seven- and eight-year-olds by adopting the priming paradigm developed by Weltzien et al [39] for a new task and sample of children.”

2. Was there an a priori decision to make the allocation task private (e.g. have the experimenter turn around) and a prediction that this would influence sharing? Again, I think the history and provenance of this study versus the Weltzien (2019) study and the a priori motivations would be helpful for providing context & highlighting the unique contributions of this study.

Our response: Yes, it was an a priori decision to make the allocation task private. As stated on page 4 (see extract above), we had two main motivations for choosing the Dictator Game: 1) it offers a wider range of sharing responses than the forced-choice sharing paradigm, and 2) it offers full anonymity.

We also return to this topic in the discussion on p. 10-11, where we write:

“The vast majority of previous cross-cultural sharing studies have used tasks taking place in view of the experimenter (e.g., [3, 4, 5, 24, 39, 48, 49, 55]). Thus, while participants often share with an anonymous receiver, the sharing typically takes place in front of a non-anonymous, adult experimenter, and herein lies a potential problem. Whereas the receiver is oblivious to the participants’ decision, the experimenter is not. Sharing decisions may therefore reflect culture-specific concerns and expectations regarding the experimenter, rather than simply being a function of social preferences [1]. While participants in the study by Weltzien et al [39] shared with an unidentified other child, the sharing allocations took place in full view of the experimenter. Participants may not be indifferent to the experimenter’s impression of their decisions. For example, participants may be concerned with appearing greedy, or wish to promote a reputation of being generous. It seems plausible that these concerns are stronger in societies that promote and emphasize the value of interdependence. The presence of the experimenter may therefore have influenced both sharing decisions overall, and the effects of the priming in the Indian population. For example, other-focus may have boosted reputational concerns in the Indian participants by triggering an awareness of the experimenter’s presence.”

3. Was there any sort of manipulation check, either in this study or a previous study, to ensure that the primes had the intended effects?

Our response: We would argue that the outcome measures are the measure of whether the primes had an effect. The questions we asked during the self- and other-focus interviews were created based on the list of independent self-construal primes (e.g., unique, alone) and interdependent self-construal primes (e.g., group, cooperate) developed by Kühnen and Hannover [50]. Kuhnen and Hannover [50] successfully used these self-construal primes in scrambled sentence tasks to manipulate perceived self–other similarity in adults, which increased after interdependence priming and decreased after independence priming. This suggests that interdependence-priming works to induce notions of relatedness in adults.

4. It would be helpful to have a clear definition of “self-construal orientation” or some explanation of what it is in both the abstract and in the introduction.

Our response: Thank you for this suggestion. The following definition has now been added to the second paragraph of the introduction on p.2:

“Self-construal can be defined as the collection of thoughts, feelings and actions concerning the self as separate from others, and the self in connection with others [10]. Consequently, one typically separates between independent and interdependent construals of self [11]. It should, however, be noted that independent and interdependent self-construals coexist in all individuals, but can be emphasised and accessed to varying degrees [10].

5. I would replace references to “universal patterns” with something like “regularities”.

Our response: “Universal patterns” has now been replaced by “consistent pattern”. Specifically, we now write on p. 2:

“Developmentally, there appears to be a consistent pattern where young children initially show a bias towards not sharing with others, but are increasingly more likely to share and to share more resources as they get older [4-7].”

6. Figure captions should include an explanation of what the error bars represent (e.g. standard deviation, standard errors, etc.)

Our response: The figure caption already includes a description of what the error bars represent. Specifically, on page 9 we write:

“Fig 2. Mean percentage of stickers shared as a function of prime type. Error bars show standard errors of the mean”.
