Everyday social interactions or goal-directed actions towards objects activate action plans appropriate to their affordances. The spatial compatibility of a stimulus and a response might interfere with the activation of these action plans. In the present study, we examined how framing of interactions affects the interplay between affordance and spatial compatibility effects towards humans and objects in two separate experiments. In a motor priming task designed to simultaneously assess these two effects, participants were presented with interactive hand gestures and objects with a single handle. Participants responded either with their left or right hand according to the colour mask of the stimulus, regardless of the spatial position or the affordance-related orientation of the stimulus. In Experiment 1, when responses were given by keypresses, we found independent affordance and spatial compatibility effects towards objects. Surprisingly, interactive hand gestures induced a reversed affordance effect, that is, imitative action tendencies. Changing the responses from keypresses to the performance of grasping actions in Experiment 2 drastically altered these findings, resulting in the enhancement of affordance and the elimination of spatial compatibility effects for both human and object interactions. These findings highlight the importance of contextual influences on the emergence of automatic action tendencies.
日常社会互动或针对物体的目标导向动作会激活与其可供性相适应的动作计划。刺激和反应之间的空间兼容性可能会干扰这些动作计划的激活。在本研究中，我们通过两个独立的实验，考察了互动框架如何影响人与物体之间的可供性和空间兼容性效应的相互作用。在一个旨在同时评估这两种效应的运动启动任务中，参与者被呈现了具有单个手柄的互动手势和物体。参与者根据刺激的颜色掩蔽，用左手或右手做出反应，而不考虑刺激的空间位置或与可供性相关的方向。在实验 1 中，当通过按键做出反应时，我们发现物体的可供性和空间兼容性效应是独立的。令人惊讶的是，互动手势引发了相反的可供性效应，即模仿动作倾向。在实验 2 中，将反应从按键改为抓握动作的执行，这一发现发生了巨大的变化，导致人与物体的互动的可供性增强，空间兼容性效应消除。这些发现强调了上下文影响对自动动作倾向出现的重要性。
