Abstract

Hand PATH (start angel & peak curvature) and TRAJECTORY (reaction time & movement time) indexes of right hand students (N=11) were studied to identify some characteristics of simple arm movements and their control process.Findings about INVARIANT CHARACTERISTICs included: 1) straight hand PATH remained the same all around the space, 2) hand PATH was independent of practice, and 3) tangential velocity profile was bell-shape and had symmetrical property. Changes of movement time were also independent from target angular position and practice. However, increased angular separation was accompanied by increased reaction time and trail set repetition was accompanied by decreased reaction time. In general, the study revealed that planning and control of hand movements are based on CARTESIAN COORDINATES.
