The perception of an action and its production are inextricably linked. This entails that, during development, the skills that children are able to perform influence their perception of others\\\'' actions. The present dissertation aimed to investigate the role of children’s experience on the perception of actions in three distinctive areas: manual actions performed by one person (individual action), manual actions performed by two people (joint action), and a conversation between two people. In order to succeed in each of the three areas, children have to acquire new skills and do so successively during their first three years of life. The methodological approach of this work was to measure the gaze behaviour of children, aged 6 months to 3 years, and adults during the observation of visually presented actions, which provided information on whether they were able to anticipate action goals. The findings obtained generally show an influence of experience on the anticipation of action goals in each of the three areas. First, a link between action and perception is not established as soon as an action emerges. There is at least some experience necessary for its development. Second, infants with no coordinated joint-action skills themselves anticipate the goals of joint action less well than those of individual action. Adults with considerable joint-action skills anticipate both equally well. And third, the course of a conversation can only be reliably anticipated by children aged 3 years and adults, whereas younger children shift their gaze between speakers randomly. Furthermore, only at the age of 3 years, did intonation support children’s anticipation of conversations.

Can cognition penetrate action-to-perception transfer? Participants observed a structure-from-motion cylinder of ambiguous rotation direction. Beforehand, they experienced one of two mechanical models: An unambiguous cylinder was connected to a rod by either a belt (cylinder and rod rotating in the same direction) or by gears (both rotating in opposite directions). During ambiguous cylinder presentation, mechanics and rod were invisible, making both conditions visually identical. Observers inferred the rod's direction from their moment-by-moment subjective perceptual interpretation of the ambiguous cylinder. They reported the (hidden) rod's direction by rotating a manipulandum in either the same or the opposite direction. With respect to their effect on perceptual stability, the resulting match/nonmatch between perceived cylinder rotation and manipulandum rotation showed a significant interaction with the cognitive model they had previously been biased with. For the “belt” model, congruency between cylinder perception and manual action is induced by same-direction report. Here, we found that same-direction movement stabilized the perceived motion direction, replicating a known congruency effect. For the “gear” model, congruency between perception and action is—in contrast—induced by opposite-direction report. Here, no effect of perception-action congruency was found: Perceptual congruency and cognitive model nullified each other. Hence, an observer's internal model of a machine's operation guides action-to-perception transfer.
