The current study examined under what condition and how the action observation influenced the object affordance. Experiment 1 investigated under what condition the imitation will facilitate (or impede) affordance through controlling the degree of speculation. In Experiment 2, when the actor's action and the action afforded by the object were matched, the object affordance effect was found both in the contact condition and uncontact condition; when they were mismatched, a reversed effect was obtained in the contact condition. Based on Experiment 2, the participants were required to respond by one hand instead of two hands in Experiment 3. None of effect was observed.
The results confirmed that when individuals assumed observed action related to object, there was interplay between imitation and affordance, suggesting competition mechanism operating between imitation system and affordance system when mismatched.
