Intergroup contact and friendship are keystones to the reduction of prejudice, yet most available data on this topic are based on indices that do not actually reflect contact or relationships. This study examined various indices of peer relations (viz., interactive companions, mutual friendships, and the stability and perceived qualities of mutual friends) for elementary school students who differed in grade, gender, and racial background; and it explored whether racial attitudes were associated with befriending or avoiding classmates. Cross-race mutual friendships declined with grade, and among fifth-graders were less likely to show 6-month stability than same-race friendships. Despite overall same-race selectivity, mutual cross-race friends, once selected, did not differ significantly from samerace ones in friendship functions such as loyalty and emotional security; only with respect to intimacy were they rated lower. Finally, racial prejudice was most strongly related to the number of excluded classmates, while children with less biased attitudes had more cross-race interactive companions and more positive perceptions of their friends.

Melodic expectancies among children and adults were examined. In Experiment 1, adults, 11-year-olds, and 8-year-olds rated how well individual test tones continued fragments of melodies. In Experiment 2, 11-, 8-, and 5-year-olds sang continuations to 2-tone stimuli. Response patterns were analyzed using 2 models of melodic expectancy. Despite having fewer predictor variables, the 2-factor model (E. G. Schellenberg, 1997) equaled or surpassed the implication-realization model (E. Narmour, 1990) in predictive accuracy. Listeners of all ages expected the next tone in a melody to be proximate in pitch to the tone heard most recently. Older listeners also expected reversals of pitch direction, specifically for tones that changed direction after a disruption of proximity and for tones that formed symmetric patterns.

This study investigated the incidence and tolerance of potentially offensive sexual behaviours in relation to the gender composition of adolescents’ friendship networks. High-school students (Grades 8 and 11) self-reported on the Sexual Experiences Questionnaire—High School and on the Social Network Form. Adolescents whose friendship network included a relatively greater proportion of other-sex friends tended to be those who experienced some form of potentially offensive sexual behaviours. However, tolerance (i.e., lack of upset) of these behaviours was not related to the gender composition of the friendship network. Moderate behaviours were perpetrated mostly by boys to both sexes, whereas severe behaviours were perpetrated by other-sex peers. The discussion addresses how sexual harassment in adolescence might be conceptualised.
