在四个长时启动实验中，以静态图片作为人体模型，考察了从不同角度观察人体动作和身体姿势的识别能力。在实验1和2中，参与者必须命名或描述图片，在实验3和4中，参与者必须决定图片是否显示可能或不可能的身体姿势。只有当启动和启动动作或姿势共享相同的深度方向（实验1和4）和左右反射（实验2和3）时，才能获得可靠的启动效应。在不同的方向上看到相同的动作或姿势并不能可靠地促进后来的识别性能，而且，对于人体不可能完成的姿势，即使使用完全相同的相同视角，也没有启动。这些研究结果表明，存储的表征，介导的人类动作和姿势的识别是特定的观点。
The identification of human actions and body postures viewed from different viewpoints was examined in four long-term priming experiments with static pictures of a human model. In Experiments 1 and 2 participants had to name or describe the pictures, and in Experiments 3 and 4 participants had to decide whether the pictures showed a possible or impossible body pose. Reliable priming effects were obtained only when priming and primed action or pose shared the same in-depth orientation (Experiments 1 and 4) and left-right reflection (Experiments 2 and 3). Having seen the same action or pose in a different orientation did not reliably facilitate identification performance later on. Also, there was no priming for poses that are impossible to perform with a human body, not even when an identical same-view prime was used. These findings suggest that the stored representations that mediate the identification of human actions and postures are viewpoint specific.
