To bind or not to bind? Different temporal binding effects from voluntary pressing and releasing actions.
First author: Zhao Ke
Abstract:

Binding effect refers to the perceptual attraction between an action and an outcome leading to a subjective compression of time. Most studies investigating binding effects exclusively employ the ‘‘pressing’’ action without exploring other types of actions. The present study addresses this issue by introducing another action, releasing action or the voluntary lifting of the finger/wrist, to investigate the differences between voluntary pressing and releasing actions. Results reveal that releasing actions led to robust yet short-lived temporal binding effects, whereas pressing condition had steady temporal binding effects up to super-seconds. The two actions also differ in sensitivity to changes in temporal contiguity and contingency, which could be attributed to the difference in awareness of action. Extending upon current models of ‘‘willed action,’’ our results provide insights from a temporal point of view and support the concept of a dual system consisting of predictive motor control and top-down mechanisms.
