Figure 1

A. Average Absolute Valence Index for 29-months-old toddlers computed over the responses to the individual questions regarding the pro-social agent and the anti-social agent separately. *p<.05 (between subjects),**p<.02 (within subjects). A positive score indicates a positive verbal statement toward the agent and vice versa for negative scores. The error bars correspond to one between-subject standard error above and below the mean. B. Average Relative Valence Index computed over the responses to the contrastive questions. A positive score indicates a more positive assessment of pro-social than the anti-social agent, vice-versa for negative scores. The error bars correspond to one between-subject standard error above and below the mean. *p<.05.
