 In a study of adults, Koestner, Zuckerman, and Olsson found that gender moderated the influence of social-comparison and mastery praise, where women were more intrinsically motivated following mastery praise, while men were more motivated following social-comparison praise.In a study of children, Henderlong Corpus, Ogle & Love-Geiger found that social-comparison praise lead to decreased motivation following ambiguous feedback for all children, and also decreased motivation following positive feedback for girls only.Thus, mastery praise may be more conducive than social-comparison to fostering intrinsic motivation, particularly for females, though more research is needed to tease apart these relationships.
