Five experiments addressed the question of whether individuals can distinguish between self-generated and other-generated actions when seeing their visual effects. Each experiment consisted of a recording session in which participants drew familiar and unfamiliar characters without receiving visual feedback and a recognition session in which they provided self-or-other judgments (SOJs) to indicate whether a kinematic display reproduced the visual effects of their own actions. The main results were that self-generated and other-generated drawing can be distinguished, that the familiarity of character shapes does not influence the accuracy of SOJs, and that velocity information is crucial for the identification of self-generated drawing. The ability to determine authorship from kinematic displays of drawing provides evidence for the contribution of action-planning structures to perception.
五项实验探讨了个体在看到视觉效果时能否区分自己产生的动作和他人产生的动作这一问题。每个实验都包括一个记录环节，在此环节中参与者绘制熟悉和不熟悉的人物，且不接收视觉反馈；还有一个识别环节，参与者在此环节中做出自我或他人判断（SOJ），以表明动态显示是否再现了他们自己动作的视觉效果。主要结果是，可以区分自己产生的绘图和他人产生的绘图，人物形状的熟悉程度不会影响自我或他人判断的准确性，并且速度信息对于识别自己产生的绘图至关重要。从绘图的动态显示中确定创作者身份的能力为动作规划结构对感知的贡献提供了证据。
