Generalizing norms and preferences within social categories and individuals.

Under what conditions will people generalize and remember observed social information? Preschool- (n = 44) and young school-age (n = 46) children and adults (n = 40) heard short vignettes describing characters' actions and motives on a single occasion. Characters were introduced using either proper names or category labels. Test questions asked for prediction and memory of motives for the same (individual) or a different (category member) person in a future event. Critical items contrasted behaviors motivated by psychological states with those motivated by normative obligations. The hypothesis was that norms would generalize across members of social categories. In contrast, psychological states would be generalized to the same individual across time. Results supported both these hypotheses and revealed some developmental differences. Preschool-age children seemed most attentive to normative properties of social categories. Young school-age children were most attentive to psychological properties of individuals. Such differences may reflect a shift from early focus on within-category similarities to a later focus on within-category differences.
