Optimizing the Control of High Index of Difficulty Movements: The Role of the Tracking Template

An experiment by Boyle, Kennedy, and Shea (2012) demonstrated that practice tracking a template created from a sine wave results in enhanced performance and transfer on a reciprocal aiming task with an index of difficulty (ID) of 6. An experiment was conducted to determine whether tracking a template constructed from recorded participantsu0027 performance with ID = 6 would provide the same benefit. Participants were assigned to one of four groups (Fitts–master, Fitts–yoked, sine–master, and sine–yoked). After acquisition, visual templates were constructed for the Fitts–yoked and sine–yoked conditions. The templates were generated from the unique displacement data of the Fitts– and sine–master participants. These made up the training template for the Fitts– and sine–yoked participants. After acquisition, all participants were asked to perform test trials under their respective acquisition conditions (Test 1) and test trials under ID = 6 reciprocal aiming conditions (Test 2). Results indicated faster movement t...
