Motor learning enhances perceptual judgment: a case for action-perception transfer.

Area of Science:

• Cognitive Psychology
• Neuroscience
• Motor Learning

Background:

• Perception-action transfer is well-documented, primarily from perception to action (e.g., observational learning).
• Transfer from action to perception (action-perception transfer, APT) has remained largely unexplored.
• APT aligns with common coding theories, suggesting shared neural mechanisms for perception and action.

Purpose of the Study:

• To empirically investigate the existence and directionality of action-perception transfer (APT).
• To examine if motor practice influences subsequent visual perception.
• To differentiate the roles of active movement versus passive kinesthetic feedback in APT.

Main Methods:

• Experiment 1: Motor practice of timed arm movements without visual feedback, followed by visual judgments of similar patterns. Also tested perception-to-action transfer.
• Experiment 2: Separated kinesthetic aspects from preparatory/efferent motor contributions to APT.
• Utilized timed two-cycle arm movements and visual pattern judgments.

Main Results:

• Evidence for bi-directional transfer between perception and action was found.
• Significant transfer from action to perception was demonstrated.
• APT effects were comparable between active motor practice and passive kinesthetic feedback groups.

Conclusions:

• Action-perception transfer (APT) is a real phenomenon, supporting bidirectional learning.
• Kinesthetic-visual transfer is a key component of APT, possibly mediated by visuomotor-kinesthetic matching or shared timekeeping mechanisms.
• Findings contribute to understanding the integration of sensory and motor systems in learning and performance.
