Cue Integration Strategy for Sense of Agency in Motor Control

Abstract

Sense of agency refers to the feeling of controlling one's actions. It acts as a “mediator” between sensory input and motor output as it can drive feedback control based on sensory feedback of movement. Sense of agency can occur using sensorimotor cues, including sensory feedback and its internal prediction or cognitive cues, such as knowledge or beliefs. The relationship between these cues is explained based on a cue integration theory in which the weight of a certain cue on the registration of agency is determined according to its relative reliability in a given situation. Based on this theory, we investigated how and which sensorimotor and cognitive cues are used for the registration of agency in motor control, thereby indicating the cue integration strategy in motor control. Accordingly, we discuss the mechanism on the registration of agency in terms of the relationship between sense of agency and motor control.
