Own-perceived body matching – the ability to match one’s own body with an observed body – is a difficult task for both general and clinical populations. Thus far, however, own-perceived body matching has been investigated in situations that are incongruent with how we are used to experience and perceive our body in daily life. In the current study, we aimed to examine own-perceived body matching in a context that more closely resembles real life. More specifically, we investigated the effects of body movement dynamics and clothing cues on own-perceived body matching. We asked participants to match their own body with an externally perceived body that was a 3D-generated avatar based on participants’ real bodies, fitted with a computer-generated dress. This perceived body was 1) either static (non-walking avatar) or dynamic (walking avatar), 2) either bigger, smaller, or the same size as participants’ own body size, and 3) fitted with a dress with a size either bigger, smaller, or the same as participants’ own dress size. Our results suggest that movement dynamics cues did not improve the accuracy of own-perceived body matching, but that confidence about dress fit was higher for dynamic avatars, and that the difference between dynamic and static avatars was dependent on participants’ self-esteem. Furthermore, when participants were asked to rate the observed body in reference to how they wanted to represent themselves to others, dynamic avatars were rated lower than static avatars for the biggest-sized bodies only, possibly reflecting the influence of movement cues on amplifying socio-cultural stereotypes. Finally, while smaller body/dress sizes were systematically rated higher than bigger body/dress sizes for several self-report items, the interplay between body and dress size played an important role in participants’ self-report as well. Thus, while our research suggests that movement and garment dynamics, allowing for realistic, concrete situations that are reminiscent of daily life, influence own-body perception, these cues did not lead to an improvement in accuracy. These findings provide important insights for research exploring (own-) body perception and bodily self-awareness, with practical (e.g. development of online avatars) and clinical (e.g. anorexia nervosa and body dysmorphic disorder) implications.

观察到的身体和自己的身体之间的感知匹配，但不是其准确性，受运动动态和服装线索的影响

自己感知的身体匹配——将自己的身体与观察到的身体相匹配的能力——对于一般人群和临床人群来说都是一项艰巨的任务。然而，到目前为止，我们已经在与我们在日常生活中习惯于体验和感知我们的身体的方式不一致的情况下研究了自己感知的身体匹配。在当前的研究中，我们旨在在更接近现实生活的环境中检查自己感知的身体匹配。更具体地说，我们研究了身体运动动力学和服装线索对自己感知的身体匹配的影响。我们要求参与者将自己的身体与外部感知的身体相匹配，该身体是基于参与者真实身体的 3D 生成化身，配有计算机生成的服装。这种感知到的身体是 1) 静态（非行走的化身）或动态的（行走的化身），2) 大、小或与参与者自身尺寸相同的尺寸，以及 3) 穿着与参与者自身尺寸相同或更大、较小或相同尺寸的连衣裙。我们的结果表明，运动动态线索并没有提高自我感知身体匹配的准确性，但动态化身对着装合身的信心更高，并且动态化身和静态化身之间的差异取决于参与者的自尊心。此外，当参与者被要求根据他们想如何向他人展示自己的方式对观察到的身体进行评分时，动态化身仅对最大尺寸的身体的评分低于静态化身，这可能反映了运动线索对放大社交的影响。文化刻板印象。最后，虽然在几个自我报告项目中，较小的身体/衣服尺寸被系统地评价为高于较大的身体/衣服尺寸，但身体和衣服尺寸之间的相互作用在参与者的自我报告中也发挥了重要作用。因此，虽然我们的研究表明，运动和服装动态，允许让人联想到日常生活的真实、具体的情况，会影响自己的身体感知，但这些线索并没有导致准确性的提高。这些发现为探索（自己的）身体感知和身体自我意识的研究提供了重要的见解，具有实际（例如在线化身的开发）和临床（例如神经性厌食症和身体变形障碍）的影响。身体和衣服尺寸之间的相互作用在参与者的自我报告中也发挥了重要作用。因此，虽然我们的研究表明，运动和服装动态，允许让人联想到日常生活的真实、具体的情况，会影响自己的身体感知，但这些线索并没有导致准确性的提高。这些发现为探索（自己的）身体感知和身体自我意识的研究提供了重要的见解，具有实际（例如在线化身的开发）和临床（例如神经性厌食症和身体变形障碍）的影响。身体和衣服尺寸之间的相互作用在参与者的自我报告中也发挥了重要作用。因此，虽然我们的研究表明，运动和服装动态，允许让人联想到日常生活的真实、具体的情况，会影响自己的身体感知，但这些线索并没有导致准确性的提高。这些发现为探索（自己的）身体感知和身体自我意识的研究提供了重要的见解，具有实际（例如在线化身的开发）和临床（例如神经性厌食症和身体变形障碍）的影响。
