Fig. 2.

Girls’ estimated marginal means of prosocial scores at pre-experiment and in “public” and “private” chat room assessments, by peer status experimental condition. Error bars represent standard errors. Figure shows untransformed prosocial scores (square root transformed scores were used in analyses to test the effects shown). Prosocial scores = responses to hypothetical scenarios; response options were in the form of a 9-point Likert scale and reflected increasing likelihood to engage in prosocial behavior, from 1 = not at all likely to 9 = definitely. Pre-experiment = scores provided privately pre-experiment; “public” chat room = scores in “public” in front of peers (i.e., in the presence of e-confederates); “private” chat room = scores provided privately and “offline” (i.e., after being “logged off” from chat room) following exposure to e-confederates’ prosocial responses. High-status and low-status conditions refer to experimental conditions based on the manipulated peer status of e-confederates
