In two experiments, we examined the role of gesture in reinterpreting a mental image. In Experiment 1, we found that participants gestured more about a figure they had learned through manual exploration than about a figure they had learned through vision. This supports claims that gestures emerge from the activation of perception-relevant actions during mental imagery. In Experiment 2, we investigated whether such gestures have a causal role in affecting the quality of mental imagery. Participants were randomly assigned to gesture, not gesture, or engage in a manual interference task as they attempted to reinterpret a figure they had learned through manual exploration. We found that manual interference significantly impaired participants' success on the task. Taken together, these results suggest that gestures reflect mental imaginings of interactions with a mental image and that these imaginings are critically important for mental manipulation and reinterpretation of that image. However, our results suggest that enacting the imagined movements in gesture is not critically important on this particular task.
在两项实验中，我们研究了手势在重新诠释心理意象中的作用。在实验1中，我们发现，与通过视觉学习到的图形相比，参与者对手通过手动探索学习到的图形做出的手势更多。这支持了这样的观点，即手势产生于心理意象过程中与感知相关动作的激活。在实验2中，我们研究了此类手势在影响心理意象质量方面是否具有因果作用。参与者在试图重新诠释通过手动探索学习到的图形时，被随机分配为做出手势、不做手势或参与手动干扰任务。我们发现，手动干扰显著损害了参与者在任务上的成功率。综合来看，这些结果表明，手势反映了与心理意象互动的心理想象，并且这些想象对于该意象的心理操作和重新诠释至关重要。然而，我们的结果表明，在这项特定任务中，通过手势做出想象中的动作并非至关重要。
