ABSTRACT
Previous research suggests that meaningful gestures in the absence of speech (i.e. pantomimed gestures) influence lexical processing, but, the extent to which pantomimes affect word retrieval is poorly understood. We investigated the relationship between pantomimes and action verb retrieval. Across two experiments, we showed that naming an action picture with a verb was facilitated by the observation of a congruent gesture, relative to both an unrelated gesture and a neutral stimulus which did not differ in their effects. Priming effects were also found to be affected by gesture transparency. This study provides the first demonstration of cross-modal gesture priming of verb retrieval in picture naming. We suggest that facilitation of verb retrieval from pantomimed gestures is consistent with priming at either the semantic level or lexical level.

Notes
1 Five pantomimed gestures could be considered as enactments of the real action (clapping, sneezing, saluting, waving and scratching) and, therefore as increased transparency might be expected for these items, correlations were also computed excluding these items: The same pattern of results was observed as for the complete item set.
2 These data were collected as part of another experiment, involving exposure to the same paradigm in two different sessions, one involving neuromodulation, here we report the results of the session without neuromodulation. Although session was counterbalanced across participants, it was nevertheless included in the model to control for any effects of this variable.
