Imageability is known to enhance association-memory for verbal paired-associates. High-imageability words can be further subdivided by manipulability, the ease by which the named object can be functionally interacted with. Prior studies suggest that motor processing enhances item-memory, but impairs association-memory. However, these studies used action verbs and concrete nouns as the high- and low-manipulability words, respectively, confounding manipulability with word class. Recent findings demonstrated that nouns can serve as both high- and low-manipulability words (e.g., CAMERA and TABLE, respectively), allowing us to avoid this confound. Here participants studied pairs of words that consisted of all possible pairings of high- and low-manipulability words and were tested with immediate cued recall. Recall was worse for pairs that contained high-manipulability words. In free recall, participants recalled more high- than low-manipulability words. Our results provide further evidence that manipulability influences memory, likely occurring through automatic motor imagery.
已知可想象性会增强对言语配对联想词的联想记忆。高可想象性的词汇可根据可操作性进一步细分，可操作性指的是与所命名对象进行功能交互的难易程度。先前的研究表明，动作加工会增强项目记忆，但会损害联想记忆。然而，这些研究分别使用动作动词和具体名词作为高可操作性和低可操作性词汇，从而将可操作性与词性混淆。最近的研究结果表明，名词既可以作为高可操作性词汇，也可以作为低可操作性词汇（例如分别为“相机”和“桌子”），这使我们能够避免这种混淆。在这里，参与者学习了由高可操作性和低可操作性词汇的所有可能配对组成的单词对，并通过即时线索回忆进行测试。对于包含高可操作性词汇的单词对，回忆效果较差。在自由回忆中，参与者回忆出的高可操作性词汇比低可操作性词汇更多。我们的结果提供了进一步的证据，表明可操作性会影响记忆，可能是通过自动运动意象发生的。
