Participants (138 children; 7-12 years of age) rated how often nice and not nice behaviors occurred when (a) participants (boys/girls) were the actor and peers (males/females) were the target and (b) when participants were the target of peers' actions in a school setting. Children indicated they were nicer to their same-gender peers than to their opposite-gender peers. Also, older boys, in comparison to young boys, indicated that not nice interactions occurred more often among them and male peers. Nice (e.g., helping) and not nice (e.g., verbal aggression) behaviors were also generated, which also differed by age and gender. Finally, this study has important implications for educators in that from children's point of view these are the types of behaviors that are occurring during their time at school. Although there are programs in schools that are aimed at decreasing physical aggression, more attention should be given to the more indirect or subtle forms of aggression, such as social manipulation and verbal. At the same time, programs that encourage nice behaviors, such as helping and sharing, should be expanded.
