  ABSTRACT: The way children evaluate the reporting of peers' transgressions to authority figures was investigated. Participants, ages 6-11 years (N = 60), were presented with a series of vignettes, each of which depicted a child who committed either a minor transgression (such as not finishing the vegetables at lunch) or a more serious transgression (such as stealing from a classmate). Participants were asked to evaluate the decision of a child observer who either did or did not report the transgression to a teacher. Younger children considered reporting to be appropriate for both types of transgressions, but older children considered reporting to be appropriate for major transgressions only. Results are interpreted with reference to (a) a changing peer culture in which the social cost of reporting transgressions increases and (b) a developmental change in children's cognitive capabilities.

  Article: Neural correlates of evaluations of lying and truth-telling in different social contexts.

  ABSTRACT: The present study examined the neural correlates of evaluations of both lying and truth-telling in different social contexts using fMRI methodology. The results demonstrated the differentiation between lying and truth-telling and between different types of lying in a network of brain regions. These regions included bilateral superior frontal gyrus (SFG), bilateral inferior parietal lobule (IPL), bilateral cuneus, right lingual gyrus (LG), right precuneus, and left postcentral gyrus (PoCG). Additionally, we found that activations in the right LG, the left IPL and the left PoCG were correlated with the off-line evaluations of truthful and untruthful communications about good and bad acts in different social contexts. These results suggest that the judgments of lying and truth-telling involving a third party might not be emotion-arousing but involve rational processing. This study is among the first to demonstrate that evaluations of truthful and untruthful communications in different social contexts can be differentiated in terms of brain BOLD (blood-oxygen-level-dependent) activities.

• Article: The neural correlates of reasoning about prosocial-helping decisions: an event-related brain potentials study.

  ABSTRACT: Providing help to others is a highly valued social practice. This study used neurophysiological methods to explore the neural correlates of individuals' reasoning about prosocial-helping behaviors and the relation between these correlates and self-reports of prosocial personality. Event-related potentials (ERP) were recorded while individuals reasoned about others' decisions to provide help or not provide help in situations where help was either obviously needed or not necessarily needed. Specific examination of the relation between self-reports of prosocial personality and the peak amplitude and latency of the P3, an ERP component considered to represent the perception and processing of a salient response, revealed that individuals' self-ratings of prosocialness were related to their ERPs. The findings from this study suggest that there are neural correlates for reasoning about prosocial-helping decisions and that there is a relation between these neural correlates and individuals' prosocial personality.
