题目：Intra-Choice Dynamics Shape Social Decisions

摘要：Do people have well-defined social preferences waiting to be applied when making decisions? Or do they have to construct social decisions on the spot? If the latter, how are those decisions influenced by the way in which information is acquired and evaluated? These temporal dynamics are fundamental to understanding how people trade off selfishness and pro-sociality in organizations and societies. Here, we investigate how the temporal dynamics of the choice process shape social decisions in three studies using response times and mouse tracking. In the first mousetracking study, participants made binary decisions in mini-dictator games with and without time constraints. Using mouse-trajectories and a starting-time drift diffusion model (stDDM), we find that, regardless of time constraints, selfish participants were delayed in processing others’ payoffs, while the opposite was true for pro-social participants. The independent mouse-trajectory analysis and computational modeling analysis identified consistent measures of the delay between considering one’s own and others’ payoffs (self-onset delay, SOD). The SOD measure correlated with individual differences in pro-sociality and predicted heterogeneous effects of time constraints on preferences. We confirmed these results in two additional studies, one a purely behavioral study in which participants made decisions by pressing computer keys, and the other a replication of the mouse-tracking study. Together these results indicate that people preferentially process either self or others’ payoffs early in the choice process. The intra-choice dynamics are crucial in shaping social preferences and might be manipulated via nudge policies for behavior in managerial or other contexts
