Abstract

The goal of the present study was to measure infants' action production and perception skills with tasks that both include goal anticipation, in a within-subject design. In the production task, the frequency of 6- and 12-month-old infants' contralateral reaching movements was examined. In the perception task, videos of contralateral movements being performed were presented to the same infants and anticipatory eye movements were analysed. The main findings were: (1) 12-month-olds used their contralateral hand more frequently than 6-month-olds; (2) 12-month-olds mainly anticipated the goals of observed actions, whereas 6-month-olds mainly followed the action; finally, and most importantly, (3) at 12 months, production and perception were linked, but at 6 months, this was not yet the case. Our results show that anticipatory eye movements do not instantly reflect infants' reaching production. A certain amount of experience is required to establish a common representation of the production and the perception of reaching movements.
