 Henderlong Corpus & Lepper found person praise (as opposed to process praise) to negatively influence motivation for older girls (4th/5th grade), while for preschool-age children, there were no differences in the effects of process, person and product praise, though all three forms of praise were associated with increased motivation as compared to neutral feedback.In a different study, Henderlong found that for older children, process praise enhanced post-failure motivation more so than person praise, and person praise decreased motivation as compared to neutral feedback.Contrastingly, for preschool-age children process praise enhanced post-failure motivation more than person praise, but both were better than neutral feedback.
