Behavioral results. A. In-scanner performance by condition. Mean values are plotted for reaction time (seconds) and accuracy (% correct) for each of the four conditions. Repeated measures ANOVA indicated a significant main effect of social interaction on reaction time such that children responded more quickly on Peer than Character trials. Error bars represent 95% confidence intervals. # p < 0.1; ** p < 0.005 B. Post-test questionnaire. For Peer and Character conditions separately, children rated on a Likert-type scale of 1 to 5 how much they enjoyed interacting with their partners (Peer) and answering questions from the computer (Character), how much they liked guessing what their partners would pick (Peer) and what came next in the story (Character), and how much they paid attention when interacting with their partners (Peer) and when answering questions from the computer (Character). Wilcoxon signed rank tests were used to compare ratings between Peer and Character conditions. # p < 0.1; ** p < 0.005
