Mechanisms underlying forward simulation in action understanding
During action observation, people represent the observed action unfolding in time and this representation
speeds up the recognition of the next action states compared to the backward states. In this talk we will
discuss the nature of this mental stimulation as well as the possible mechanisms underlying action
anticipation. We hypothesize that there are at least two processes: (1) an action prediction mechanism, by
which people simulate the next states of the observed action through a representation of the action
unfolding in time; (2) a goal prediction mechanism, by which people infer the final goal of the observed
action based on the physical properties of the object.
