Prosocial effects of coordination - What, how and why?

A wealth of research in recent decades has investigated the effects of various forms of coordination upon prosocial attitudes and behavior. To structure and constrain this research, we provide a framework within which to distinguish and interrelate different hypotheses about the psychological mechanisms underpinning various prosocial effects of various forms of coordination. To this end, we introduce a set of definitions and distinctions that can be used to tease apart various forms of prosociality and coordination. We then identify a range of psychological mechanisms that may underpin the effects of coordination upon prosociality. We show that different hypotheses about the underlying psychological mechanisms motivate different predictions about the effects of various forms of coordination in different circumstances.
