Social-emotional evaluations of unfamiliar people are negatively impacted by ignoring or withholding motor-responses from images that depict them; an effect attributed to the propensity of inhibition to affectively devalue associated stimuli. Prior findings suggest that the social-emotional consequences of inhibition may operate on category-level representations that impact all members of a corresponding group. Here we assess whether such social-emotional consequences of motor-response action versus inaction also operate on item-level representations of specific individuals. Participants memorized individual identities of a group of fellow students before completing a Go/No-go response-inhibition task designed to associate item-level representations of each previously-memorized person with action (Go trials) or inaction (No-go trials). Social identities associated with action were consistently rated as more trustworthy in subsequent evaluations than those associated with inaction. This suggests that the social-emotional consequences of motor-response execution versus inhibition can operate on item-level stimulus representations in memory.

对陌生人的社会情感评价会因忽略或保留描述他们的图像中的运动反应而受到负面影响；一种归因于抑制倾向性地使相关刺激贬值的效应。先前的发现表明，抑制的社会情感后果可能在影响相应群体所有成员的类别层面的表现上起作用。在这里，我们评估了动作反应与不作为之间的这种社会情感后果是否也适用于特定个体的项目级表示。参与者在完成“去/不去”反应抑制任务之前记住了一组同学的个人身份，该任务旨在将每个先前记忆的人的项目级别表示与行动（“去”试验）或不作为（“去”试验）联系起来。在随后的评估中，与行动相关的社会认同始终比与不行动相关的社会认同更值得信赖。这表明运动反应执行与抑制的社会情感后果可以作用于记忆中的项目级刺激表示。
