The relation between attractiveness and motor affordance is a key topic in design and has not yet been investigated electrophysiologically. In this respect, action affordance and attractiveness represent two crucial dimensions in object processing (specifically for tools). In light of this evidence, Event Related Potentials (ERPs) enabled us to gain new insights into the time course of the interaction between these two dimensions during an explicit tool evaluation task. Behaviorally, tools that were judged as high affording and high attractive yielded faster response times than those judged as low affording and low attractive. The ERP results showed that early processes related to sensory gating and feature extraction (N100) were sensitive to both affordance and attractiveness; the P200 was dominated by affordance, indexing a facilitated access to motor action representation. The N300, P300 and the Late Positive Potential (LPP) showed enhanced responses for highly affording/attractive tools, reflecting the interconnection between attractiveness and affordance. Later responses were entirely affected by attractiveness, suggesting additional affective responses evoked by desirable tools. We are showing that things that are perceived as more functional and attractive have a privileged neural activation in the time course of tool evaluation, for the first time.
吸引力与运动可供性之间的关系是设计领域的一个关键话题，尚未从电生理学角度进行研究。在这方面，动作可供性和吸引力是物体加工（特别是工具加工）中的两个关键维度。鉴于此证据，事件相关电位（ERP）使我们能够在一项明确的工具评估任务中，对这两个维度之间相互作用的时间进程有新的认识。在行为层面，被判定为高可供性和高吸引力的工具比被判定为低可供性和低吸引力的工具产生更快的反应时间。ERP结果表明，与感觉门控和特征提取相关的早期过程（N100）对可供性和吸引力均敏感；P200受可供性主导，表明对运动动作表征的访问得到促进。N300、P300和晚期正电位（LPP）对高可供性/高/高吸引力的工具表现出增强的反应，反映了吸引力和可供性之间的相互联系。后期反应完全受吸引力影响，表明理想工具引发了额外的情感反应。我们首次表明，在工具评估的时间进程中，被认为更具功能性和吸引力的事物具有优先的神经激活。
