Abstract: Little is known about the effect of aging on the recognition of gestures. The present study was designed to answer this question. Three groups of adults were assessed: (a) 30 subjects aged from 20 to 36 years; (b) 30 subjects aged from 40 to 55 years; (c) 54 subjects aged from 60 to 75 years. The protocol tested 5 tasks: (1) gesture decision; (2) recognition of correct gestures, (3) similarity judgment; (4) gesture designation; (5) gesture naming. Significant differences were found in tasks 3 and 5. These results were interpreted as difficulties located in the gesture lexicon or the semantic system.
