Academic achievements

Prinz is the father of the common coding theory. This theory claims parity between perception and action. Its core assumption is that actions are coded in terms of the perceivable effects (i.e., the distal perceptual events) they should generate Performing a movement leaves behind a bidirectional association between the motor pattern it has generated by and the sensory effects that it produces. Such an association can then be used backwards to retrieve a movement by anticipating its effects. These perception/action codes are also accessible during action observation (for an historical account of the ideo-motor principle, see Observation of an action should activate action representations to the degree that the perceived and the represented action are similar. Such a claim suggests that we represent observed, executed and imagined actions in a commensurate manner and makes specific predictions regarding the nature of action and perceptual representations. First, representations for observed and executed actions should rely on a shared neural substrate. Second, a common cognitive system predicts interference effects when action and perception attempt to access shared representations simultaneously. Third, such a system predicts facilitation of action based on directly prior perception and vice versa.

The common coding theory has received strong support from a variety of empirical studies in developmental psychology, cognitive neuroscience, cognitive science and neurophysiology. This theory is at the core of what has been called Motor cognition. In neuroscience, evidence for the common coding theory ranges from electrophysiological recordings in monkeys in which mirror neurons in the ventral premotor and posterior parietal cortices fire both during goal-directed actions and observation of the same actions performed by another individual, to functional neuroimaging experiments in humans which indicate that the neural circuits involved in action execution partly overlap with those activated when actions are observed.
