A series of studies investigated the capacity of children between the ages of 7 and 12 to give free and informed consent to participation in psychological research. Children were reasonably accurate in describing the purpose of studies, but many did not understand the possible benefits or especially the possible risks of participating. In several studies children's consent was not affected by the knowledge that their parents had given their permission or by the parents saying that they would not be upset if the children refused. In contrast, other studies found that children were much more likely to stop their participation if the experimenter said explicitly that she would not be upset if they stopped. We suggest that experimenters should pay more attention to describing the possible risks and benefits of participation in research, and that they should also make it clearer to children that they are free to stop once they have begun.

Effects of hosts' conflicting motives (to win a game vs. to be a good friend) on peer group entry processes and outcomes were examined. Subjects were 68 triads (35 female) of 10-12-year-old predominantly White children. Two host friends played a game for a large prize that was forfeited for a smaller prize if the guest (a friend or nonfriend of both hosts) was included. Hosts admitted guest friends more often than nonfriends (44% vs. 26%), suggesting that friendship norms prescribe self-sacrifice. Hosts behaved similarly with guest friends and nonfriends, but guest friends were more active than nonfriends, reflecting freedom derived from friendship security. Female hosts admitted guests more often than male hosts (51% vs. 21%), consistent with communal and agentic gender role prescriptions for girls and boys, respectively. Results suggest that hosts' friendship obligations and psychological orientation affect their response to a newcomer in a group entry situation.

This review of literature focuses on aggression and adolescent girls. Recent official crime statistics from Statistics Canada show an increase in violent offences by girls. This statistic has created considerable interest in a heretofore largely ignored area of childhood maladjustment. Important differences regarding the development and expression of aggression with girls in contrast to boys is provided. In the context of what is acknowledged to be a limited literature, there are important themes for human service-providers and policy-makers to consider in examining assessment, treatment, and prevention strategies for aggressive adolescent girls. Finally, an orientation towards furthering a research agenda in the area of aggression with adolescent girls is provided. Overview of Violence and Adolescent GirlsConcern with respect to violence and young people in Canada is now without precedence. Fear amongst Canadians for the out-of-control behaviour of young
