行為を実演した記憶と想像した記憶の違い : ソース・モニタリング課題による検討

抄録

The differences between memories of enacted actions and imagined actions were investigated by using two kinds of source monitoring (SM) tasks. Experiment 1 involved an internal SM task in which the participants were instructed to perform, imagine, or vocalize the actions described in sentences. They were then given a recognition test, and if they recognized a sentence they were asked whether they had performed, imagined, or vocalized it. In Experiment 2 an external SM task was used and the action sentences were presented by either a male or female voice. The participants were instructed to perform, imagine, or vocalize each sentence, and then took a recognition test. If they recognized a sentence they were asked which voice presented it. The results showed that in the internal SM task (Exp. 1), there were fewer SM errors for the enacted condition than for the imagined condition. A difference was not found for these conditions in the external SM task (Exp. 2). These findings suggest that enactment, rather than imagining, facilitates internal but not external SM processing.
