Abstract
Previous studies using intermodal semantic priming have found that gestures improve language memory. In the present study, we ask whether the inherent characteristics of representative gestures (iconic gestures) facilitate word memory, or it is simply the semantic content shared with the words. Two analogous experiments were carried out presenting iconic gestures, pictures, or null primes to target words (nouns and action verbs). In Experiment 1, participants performed a free word recall task. In Experiment 2, the task was one of recognition. The results showed that participants recalled (Experiment 1) an equivalent number of words preceded by gestures or pictures compared with words alone, with no prime. However, a significantly higher number of words were recognised (Experiment 2) when they were primed by iconic gestures compared with the other two conditions, an advantage also found in reaction times (RTs) and both effects being larger in verbs than in nouns. These findings are discussed regarding the differences between recall and recognition processes as well as the particular characteristics of representative gestures.
