Length of male and female friendship and perceived intelligence in self and friend.

The Self-Rating Scale of Intelligence (SRSI) and the Otis intelligence test were administered to -20 pairs each of same-sex long-acquaintance males and females and 12 pairs each of same-sex short-acquaintance males and females. The SRSI provided subjects with the opportunity to make intelligence attributions to self, friend, and ideal friend and to provide the expected rating of self by the friend and people-in-general. Significant positive correlations were obtained from relating the within-person perceptions, while nonsignificant correlations were obtained from the relation of perceptions and objectively measured intelligence between friends. Self-concept support from the friend and from people-in-general were the more significant relationships identified across groups.
