  • The relationship between imagery, iconic gesture production, and speech was assessed among 120 participants in a narrative task. Study 1 indicated no significant relationship between visuospatial working memory capacity and iconic gesture production, and demonstrated that when visual interference is eliminated, iconic gesture rate decreases. Study 2 provided evidence that as visual interference increases in difficulty, participants use iconic gestures to a greater extent. Study 3 provided suggestive evidence that as auditory interference increases in difficulty, participants use iconic gestures to a greater extent. With respect to speech production, strong associations between narrative length and iconic gesture production were demonstrated in every condition except for when visual perceptual interference was eliminated. These results were interpreted within a framework of embodied cognition wherein iconic gesture production and imagery interact bi-directionally to facilitate the activation of imagistic representations and speech production.
