Previous studies suggested that the language production architecture is recruited during verbal retention, and others proposed that spatial memory relies on the oculomotor system. The objective of the present study was to investigate the role of the motor system in object memory, by examining the effect of objects' affordances on retention. In a serial recall task, we manipulated the manipulability of objects to retain in memory. We used an isolation paradigm where we isolated the manipulability level of one object from the list. We showed that recall performance improved for the isolated object (Experiment 1) and that this advantage was abolished when participants were required to perform motor suppression during the task (Experiment 2). In Experiment 3, we showed that the abolition of the motor isolation effect in Experiment 2 was not due to an effect of distraction since motor suppression was shown not to interfere with a semantic isolation effect. It is argued that motor affordances play a role in object memory, but only when the motor characteristics of an object allow discriminating it from the other objects in the list.
先前的研究表明，语言生成架构在言语记忆过程中会被调用，还有其他研究提出空间记忆依赖于眼动系统。本研究的目的是通过考察物体可供性对记忆保持的影响，来探究运动系统在物体记忆中的作用。在一个系列回忆任务中，我们操控要记忆的物体的可操作性。我们采用了一种隔离范式，即将列表中一个物体的可操作性水平分离出来。我们发现，对于被隔离的物体，回忆表现有所提高（实验1），并且当参与者在任务过程中需要进行运动抑制时，这种优势就消失了（实验2）。在实验3中，我们表明实验2中运动隔离效应的消除并非由于分心效应，因为运动抑制并未干扰语义隔离效应。研究认为，运动可供性在物体记忆中发挥作用，但前提是物体的运动特征能够使其与列表中的其他物体区分开来。
