A Trait–State Model of Bystander Intervention

Le résumé fourni par la source

Bystanders are critical actors who can meaningfully shape how harmful situations unfold. Drawing on data collected in Virtual Reality (VR) as part of a larger study, the present research examines the psychological processes underlying bystander decision-making by investigating how personality traits and affective and cognitive states jointly shape bystander intervention. We conceptualize facilitative and inhibitory processes as state-level mechanisms through which personality traits shape bystander intervention decisions. Our primary focus is on violent bystander intervention. Nevertheless, we also investigate non-violent intervention exploratorily. The basic model specifies anger as a facilitative pathway to bystander violent intervention, and fear and anticipated guilt/shame as inhibitory pathways. Beyond these affective processes, we also examine several cognitive mechanisms—namely perceived risk, perceived (un)acceptability of violent intervention, and perceived responsibility—that jointly shape facilitative and inhibitory pathways to bystander violent intervention.
