Graphic-motor adaptation to computer distortions between coordinates of the visual and motor fields

Abstract

The article presents. The paper is devoted to perceptual-motor coordination and adaptation in the conditions of computer distortion between the coordinates of motor and visual fields. We studied experimentally changes and relationship between the speed and accuracy of motor execution at different angular displacements of the computer mouse movement, adaptation to the changed conditions of the cursor movement perception, gender differences in speed and quality of the graphic-motor task. The experiment was carried out in a computer version. It is used nine conditions of angular displacements (from 0° to 180°). 25 subjects participated in the experiment: 12 women and 13 men aged 17-25 years. According to the results, speed and accuracy of the graphic-motor task are decreasing with increasing angular displacement (p<0,001). We identified three groups of angular displacement according to the degree of accuracy and adaptation. The largest range of values and errors is observed at the angular displacement in 135°. At small angular displacements (less 75°) the increase of execution time leads to accuracy improvement, but at the angles more than 90° it leads to accuracy decline. Gender differences were at the level of statistical trend (p=0,087) — men performed tasks faster and more accurately than women, but adaptation to the changed conditions was almost equal
