Beep, Aim, Repeat: Influence of Use-dependent and Advance Preparation Processes during Sequential Movements
Year: 2019
Type: dissertation
Abstract: Sequential goal-directed actions can be influenced by both recent motor history, and the characteristics of planned movements. That is, the current movement can be biased toward the direction of a preceding target and/or an upcoming target through the activation of movement planning mechanisms associated with repeated motor sequences: use-dependent and advance preparation processes, respectively. Although the two motor planning processes have been studied independently, how these processes interact with one another is not well understood. The present studies were thus designed to differentiate the characteristics of use-dependent and advance preparation processes during the repetition of movement sequences. Participants completed a sequential aiming task, where the factors such as orientation of the targets, availability of vision, type of movements, and presentation of trials were manipulated. Although the studies did not clearly indicate the individual contribution of use-dependent and advance preparation processes, there was some evidence suggesting co-activation of the two processes.
