Age trends in conformity and independence, using a sample of 366 children from the 1st, 4th, 7th, and 10th grades were investigated. Three types of stimuli were used: (1) visual judgments; (2) opinion statements; and (3) delay of gratification preferences. Age-trends were observed for unanimous peer pressure, adult influence, and peer pressure with social support from a partner. Unanimous peer pressure yielded decreasing conformity across age, being more pronounced for males than for females. Adult influence declined over age for both sexes. Social support from a partner who gave correct or modal answers reduced conformity to a constant low level across all ages. The report concludes that mechanisms of group influence are highly similar across age, and that age trends may reflect variations in situational factors associated with age differences. Hence, the variable of age may be of limited value, in itself, in studying peer influence. (Author/TL)
