Precise force controls enhance loudness discrimination of self-generated sound

Motor executions alter sensory processes. Studies have shown that loudness perception changes when a sound is generated by active movement. However, it still unknown where and how the motor-related in depend on task demand of motor execution. We examined whether different levels precision demands control affects perception. carried out discrimination test, which stimulus was produced conjunction with force generation task. tested three target amplitude levels. The presented monitor as fixed visual target. also same movement cursor. Participants adjusted their predetermined range without overshooting using these targets moving In condition, stimuli were externally (without task). found performance significantly improved compared to externally, although we did not find this improvement changed depending results suggest for precise produce amount may be key obtaining facilitatory effect execution auditory
