Does phonological similarity affect gesture production in the absence of speech? Participants produced gestures from pictures with no words presented or spoken. Same pictures and gestures but different training labels were used. Phonologically similar labels led to more errors in subsequent gestures. Thus, phonological similarity affects gesture production in the absence of speech.
Are manual gestures affected by inner speech? This study tested the hypothesis that phonological form influences gesture by investigating whether phonological similarity between words that describe motion gestures creates interference for production of those gestures in the absence of overt speech. Participants learned to respond to a picture of a bottle by gesturing to open the bottle's cap, and to a picture of long hair by gesturing to twirl the hair. In one condition, the gestures were introduced with phonologically-similar labels “twist” and “twirl” (
