先前的研究表明，即使在没有视觉经验的情况下，动作的运动经验也可以促进对该动作的视觉识别。我们进行了一项实验，参与者被呈现在点光显示器上的舞蹈动作，这些动作是在前一次会议期间由同一组参与者记录的。刺激已经与参与者以这样一种方式产生，即每个参与者仅作为观察者经历短语的子集，从观察中学习两个短语，并在蒙住眼睛的情况下创建一个短语。在识别任务中呈现的片段显示了不熟悉的动作，仅在视觉上熟悉的动作，通过观察学习和执行而熟悉的动作，或者在被蒙住眼睛时自己创造的动作（因此在视觉上不熟悉）。参与者将所有类型的动作正确地分配到相应的类别中，这表明体验运动的所有三种方式（观察，通过观察和实践学习，以及蒙上眼睛创建）都产生了足以识别的编码。观察到的动作显示出最低水平的识别准确性，而分配蒙眼自创动作的准确性是在同一水平上的不熟悉和学习的动作。自我识别调制的动作识别，参与者更有可能确定自己的演员在剪辑中，他们分配到类别“创建”比在剪辑中，他们分配到类别“学会”，支持的想法的影响力的机构对自我识别。
Previous research has shown that motor experience of an action can facilitate the visual recognition of that action, even in the absence of visual experience. We conducted an experiment in which participants were presented point-light displays of dance-like actions that had been recorded with the same group of participants during a previous session. The stimuli had been produced with the participant in such a way that each participant experienced a subset of phrases only as observer, learnt two phrases from observation, and created one phrase while blindfolded. The clips presented in the recognition task showed movements that were either unfamiliar, only visually familiar, familiar from observational learning and execution, or self-created while blind-folded (and hence not visually familiar). Participants assigned all types of movements correctly to the respective categories, showing that all three ways of experiencing the movement (observed, learnt through observation and practice, and created blindfolded) resulted in an encoding that was adequate for recognition. Observed movements showed the lowest level of recognition accuracy, whereas the accuracy of assigning blindfolded self-created movements was on the same level as for unfamiliar and learnt movements. Self-recognition was modulated by action recognition, as participants were more likely to identify themselves as the actor in clips they had assigned to the category “created” than in clips they had assigned to the category “learnt,” supporting the idea of an influence of agency on self-recognition.
