ABSTRACT

Research on interceptive reaching tends to be divided into one of two distinct categories, viz.: reaching towards a stationary target, and dynamic interception of a moving target. Stationary-reaching research has focused on the key timing characteristics of the transport and grasp-components and how the accelerative and decelerative phases are adapted to meet differing task demands. This chapter investigates which elements of the transport phase of an interceptive reach towards a moving target are adjusted to meet the spatial and temporal requirements of a task under varying instructional constraints. The analysis of interceptive actions of moving targets has focused on the nature of the prospective information used to guide the movement and the strategies employed to regulate it. A new t-coupling analysis is introduced by analyzing the continuous ratios of the ts of motion gaps.
