The present study aimed to further explore the role of the head for configural body processing by comparing complete bodies with headless bodies and faceless heads (Experiment 1). A second aim was to further explore the role of the eye region in configural face processing (Experiment 2). Due to that, we conducted a second experiment with complete faces, eyeless faces, and eyes. In addition, we used two effects to manipulate configural processing: the effect of stimulus inversion and scrambling. The current data clearly show an inversion effect for intact bodies presented with head and faces including the eye region. Thus, the head and the eye region seem to be central for configural processes that are manipulated by the effect of stimulus inversion. Furthermore, the behavioural and electrophysiological body inversion effect depends on the intact configuration of bodies and is associated with the N170 as the face inversion effect depends on the intact face configuration. Hence, configural body processing depends not only on the presence of the head but rather on a complete representation of human bodies that includes the body and the head. Furthermore, configural face processing relies on intact and complete face representations that include faces and eyes.
本研究旨在通过比较完整的身体、无头的身体和无脸的头部，进一步探索头部在身体整体加工中的作用（实验 1）。第二个目的是进一步探索眼区在面部整体加工中的作用（实验 2）。为此，我们用完整的面部、无眼的面部和眼睛进行了第二个实验。此外，我们使用了两种效果来操纵整体加工：刺激反转和打乱效果。目前的数据清楚地显示，完整的身体呈现出头部和面部（包括眼区）的反转效果。因此，头部和眼区似乎是受刺激反转效果影响的整体加工的核心。此外，行为和电生理的身体反转效应取决于身体的完整配置，与 N170 面部反转效应取决于完整的面部配置有关。因此，整体身体加工不仅取决于头部的存在，还取决于包括身体和头部在内的完整的人体表示。此外，整体面部加工依赖于包括面部和眼睛在内的完整和完整的面部表示。
