尽管行动识别和歧视在更广泛的行动感知和社会认知中的重要性，但很少有研究调查这些过程是如何实现的。为此，我们试图确定成年人在区分诸如抓握和放置等小规模人类行为时利用特征信息来源和配置信息来源的程度。两个实验的结果表明，成人在动作辨别中对两种信息来源都很敏感，但有选择性地关注特征信息而不是构形信息。这些发现也与已知的人脸处理相似：构型信息的处理尤其受到反转的干扰，而特征信息的处理则特别受到低通滤波的影响。
Despite the importance of action identification and discrimination in action perception and social cognition more broadly, little research has investigated how these processes are achieved. To this end, we sought to identify the extent to which adults capitalize on featural versus configural sources of information when discriminating small-scale human actions such as grasp and place. Results across two experiments indicate adults are sensitive to both sources of information in action discrimination, but selectively attend to featural over configural action information. The findings also parallel what is known regarding face processing: processing of configural information is especially disrupted by inversion, whereas processing of featural information is specifically affected by low-pass filtering.
