actionperception

Actionperception is the study of the intertwined relationship between motor action and perceptual processing. It posits that perception is not passive reception of sensory data but is shaped by the organism’s actions and goals, while action is guided by ongoing perceptual input. The concept emphasizes sensorimotor integration and active sensing, where movement and exploration alter the information available to the observer and vice versa.

Key ideas include sensorimotor contingencies—predictable perceptual changes caused by movement—along with mechanisms such as efference copy and corollary discharge. Predictive coding frameworks describe the brain as generating forecasts of the sensory consequences of actions to minimize prediction error. Perception is thus an active inference process. Gibsonian affordances describe how environments offer action possibilities perceived directly, linking perception to potential behavior.

Neural and theoretical perspectives highlight circuits in the premotor and parietal regions that support action-perception coupling, including networks associated with action execution, observation, and planning. Mirror-neuron systems are often cited as a neural substrate for linking seeing and doing. Enactive and ecological theories emphasize that perception arises through embodied engagement with the world and is inseparable from potential action.

Applications and methods span robotics, rehabilitation, sports science, and human-computer interaction, where tight integration of sensing and movement is essential. Researchers study actionperception through behavioral sensorimotor tasks, neuroimaging, stimulation techniques, and computational modeling to understand how perception and action shape learning, adaptation, and plasticity.
