In complex interactive scenarios, action understanding lies at the heart of social interactions. Nevertheless, the ability to understand action intention may differ among people. The current study distinguished two groups of participants with different social intention-understanding abilities (high and low) based on a perspective-taking task to investigate the influence of social intention on object affordance under conditions of individual and cooperative action intention. In the affordance perception experiment, participants were shown a video with the presenter reaching to grasp an object in different grips and asked to classify objects into kitchen or non-kitchen items by pressing the left- or right-hand button under the two intention conditions. The results showed that the object affordance effects were modulated by the participants’ understanding of social intention in the interactive scenarios. Specifically, the object affordance effects were observed only in the high perspective-taking ability group under the condition of cooperative action intention. However, under the condition of individual action intention, object affordance effects were shown in both the high and low perspective-taking ability groups, and the difference between the two groups was not significant. This study suggests that processing of object affordance depends greatly on the contextual correspondence of perception and action and that the understanding of cooperative action intention can affect the activation of object affordance.

在复杂的交互场景中，动作理解是社交交互的核心。然而，理解行动意图的能力可能因人而异。目前的研究基于透视任务区分了两组具有不同社会意图理解能力（高和低）的参与者，以调查在个人和合作行动意图条件下社会意图对对象可供性的影响。在示能感知实验中，向参与者展示了一段视频，演示者伸手去抓一个不同抓握的物体，并要求在两种意图条件下通过按下左手或右手按钮将物体分类为厨房或非厨房物品。结果表明，对象可供性效果受到参与者对交互场景中社会意图的理解的调节。具体而言，仅在合作行动意向条件下的高视角采取能力组中观察到对象启示效应。但在个体行动意向条件下，高、低视角采取能力组均表现出客体示能效应，两组差异不显着。本研究表明，对象可供性的处理很大程度上取决于感知和动作的上下文对应关系，并且对合作行动意图的理解可以影响对象可供性的激活。仅在高视角采择能力组在合作行动意向条件下观察到客体启示效应。但在个体行动意向条件下，高、低视角采取能力组均表现出客体示能效应，两组差异不显着。本研究表明，对象可供性的处理很大程度上取决于感知和动作的上下文对应关系，并且对合作行动意图的理解可以影响对象可供性的激活。仅在高视角采择能力组在合作行动意向条件下观察到客体启示效应。但在个体行动意向条件下，高、低视角采取能力组均表现出客体示能效应，两组差异不显着。本研究表明，对象可供性的处理很大程度上取决于感知和动作的上下文对应关系，并且对合作行动意图的理解可以影响对象可供性的激活。高、低视角采取能力组均表现出客体启示效应，两组间差异不显着。本研究表明，对象可供性的处理很大程度上取决于感知和动作的上下文对应关系，并且对合作行动意图的理解可以影响对象可供性的激活。高、低视角采取能力组均表现出客体启示效应，两组间差异不显着。本研究表明，对象可供性的处理很大程度上取决于感知和动作的上下文对应关系，并且对合作行动意图的理解可以影响对象可供性的激活。
