From the perception of action to the understanding of intention

Humans have an inherent tendency to infer other people's intentions from th eir actions. Here we review psychophysical and functional neuroimaging evid ence that biological motion is processed as a special category, from which we automatically infer mental states such as intention. The mechanism under lying the attribution of intentions to actions might rely on simulating the observed action and mapping it onto representations of our own intentions. There is accumulating neurophysiological evidence to support a role for ac tion simulation in the brain.
