Defending peers who have been bullied is often thought to put defenders at risk of becoming victimized themselves. The study investigated the concurrent and prospective associations between defending and (peer- and self-reported) victimization, and examined popularity and classroom norms as potential moderators. Participants included 4085 Finnish…

This study examined the developmental profiles of children's social reasoning about individual agentive and deontic concerns. Tongan children (N = 140, 47.9% male), aged 4-8 years, were given a set of mentalistic (standard theory-of-mind) and deontic reasoning tasks. On average, children found diverse desires, knowledge access, hidden emotion, and…

This study investigates possible individual and class correlates of defending and passive bystanding behavior in bullying, in a sample of 1,825 Italian primary school (mean age = 10 years 1 month) and middle school (mean age = 13 years 2 months) students. The findings of a series of multilevel regression models show that both individual (e.g.,…

The team was threatened or not threatened by an out-group that was…

Three principles of work distribution were considered: (1) direct cause; (2) self-regulation; and (3) continuing responsibility. Children of 8, 11, and 14 years of age performed a job sorting task and commented on the fairness of work arrangements in vignettes. Results showed a differential development for the three principles rather than a…

First- and fifth-grade kibbutz and city children (320 in two studies) individually were requested to distribute rewards between themselves and a partner who had produced either more or less than the subject had. Fifth graders were also asked about the level of effort and merit displayed by themselves and their partners. (Author/RH).
