When Prosocial Dispositions Become Effective Help: The Prosocial Translation Model

Full abstract

Abstract

Why does the same person help in one moment but not another, and why do people with similar prosocial intentions produce different outcomes? Dispositional accounts identify relatively stable tendencies associated with helping, while situational accounts identify conditions that permit or suppress action. Both approaches often treat helping as a single endpoint. This critical integrative review develops the Prosocial Translation Model (PTM), a person × situation theory in which effective help is an episode-level accomplishment across functionally distinct transitions: opportunity exposure, recognition of need, acceptance of responsibility, response selection, enactment, and recipient benefit. The PTM makes four commitments. It separates exposure from conversion, models person attributes and situational affordances at the transitions they can plausibly influence, distinguishes intention and completed action from recipient benefit, and requires comparison with simpler and bypass architectures. A corrected probability formulation defines the canonical pathway as a joint event rather than equating it with benefit alone. The model also distinguishes observed improvement from causal net benefit. Ten falsifiable propositions specify differentiated translation profiles, stage-matched interactions, situational substitution and amplification, gated intervention effects, held-out joint calibration, selection into helping ecologies, transition-specific learning, resource constraints, and action-outcome divergence. A measurement framework and four-study program show how the PTM can be preregistered, tested, and rejected. The model’s proposed contribution is not a new list of helping stages. It is an opportunity-adjusted, multilevel, recipient-centered architecture for explaining when prosocial dispositions become consequential for others.
