 Eagly and Chrvala examined the role of age (under 19 years vs. 19 years and older), gender and surveillance (anticipating responses to be shared with group members vs. not anticipating responses being shared) on conformity to group opinions.They discovered that among participants that were 19 years or older, females conformed to group opinions more so than males when under surveillance (i.e., anticipated that their responses would be shared with group members).However, there were no gender differences in conformity among participants who were under 19 years of age and in surveillance conditions.
