Affiliative stimuli are pleasant and highly biologically relevant. Affiliative cues are thought to elicit a prosocial predisposition. Here affiliative and neutral pictures were exposed prior to a reaction time task which consisted in responding to a visual target. Half the participants responded with finger-flexion, a movement frequently involved in prosocial activities. The other half responded with finger extension, a less prosocially compatible movement. Results showed that under the exposure to affiliative pictures, as compared to neutral ones, participants who used finger flexion were faster, while those using finger extension were slower. Performance benefits to the task, when flexing the finger, together with performance costs, when extending it, indicate the relevance of movement compatibility to the context. These findings put forward a possible link between affiliative primers and motor preparation to facilitate a repertoire of movements related to prosocial predispositions including finger flexion.
亲和刺激是令人愉悦的，具有高度的生物学相关性。亲和线索被认为能引发亲社会倾向。在这里，亲和和中性的图片会在反应时间任务之前呈现，该任务包括对视觉目标做出反应。一半的参与者用手指弯曲做出反应，这是一种经常涉及亲社会活动的动作。另一半参与者则用手指伸展做出反应，这种动作与亲社会行为不太兼容。结果表明，与中性图片相比，在暴露于亲和图片的情况下，使用手指弯曲的参与者反应更快，而使用手指伸展的参与者反应更慢。当弯曲手指时，参与者在任务中的表现会得到提升，而当伸展手指时，表现则会下降，这表明运动兼容性与上下文相关。这些发现提出了亲和启动和运动准备之间可能存在联系，以促进与亲社会倾向相关的一系列动作，包括手指弯曲。
