Affect Infusion Model (AIM)

An integrative theory explaining how affective states influence social judgments. The Affect Infusion Model (AIM) proposes a multiprocess approach to social judgments and identifies 4 alternative judgmental strategies: (a) direct access, (b) motivated, (c) heuristic and (d) substantive processing. The model predicts that the degree of affect infusion into judgments varies along a processing continuum, such that judgments requiring heuristic or substantive processing are more likely to be infused by affect than are direct access or motivated judgments
