 While praise may share some predictive relationships (both positive and negative) with tangible (material) rewards, praise tends to be less salient and expected, conveys more information about competence, and is typically given more immediately after the desired behavior.Praise is distinct from acknowledgement or feedback (more neutral forms of recognition) and from encouragement (expressedly future-oriented).Praise is given across social hierarchy, and both within the ingroup and towards an outgroup; it is an important aspect in the regulation of social hierarchy and the maintenance of group cohesion, influencing the potential for political action and social upheaval.
