This theoretical article summarizes the various psychological and motivational processes that underlie prosocial decision-making. To this aim, we propose a novel way to organize and synthesize research related to emotions, thoughts, and beliefs (i.e., psychological mechanisms) that motivate or demotivate human prosociality. This is done with a new typology including four overarching interrelated categories, each encompassing multiple subcategories: (a) emotions; (b) moral principles; (c) anticipated impact; and (d) anticipated personal consequences. We highlight differences and commonalities to other influential frameworks and showcase how the proposed typology can help researchers and practitioners better differentiate and understand the diverse psychological mechanisms that underlie human prosociality.
