However, the mechanism underlying this mnemonic effect of a multimodal presentation was not fully specified. It may depend on activation of mental images and/or on increased distinctiveness of gestured utterances. The present study compared memory for sentences accompanied by different kinds of gestures—representational and nonrepresentational—to assess the role of meaning in remembering the verbal material. The results of the first experiment indicated that presentation of nonrepresentational gestures did not increase sentence recall as representational gestures did. These representational gestures also influenced performance in a sentence recognition task. In the second …
