Dimensional analysis of motion: IX. Comparison of visual and nonvisual control of component movements

Abstract

Twelve Ss practiced a knob-turning control panel task while blindfolded, and another 12 without blindfolds. A final set of trials was run in which the visual conditions were reversed for the Ss. Time of travel (hand movement) to reach the knobs, and time of manipulation, were recorded electronically. For both components, the non-blindfold group did better; practice did not compensate for loss of vision. (PsycInfo Database Record (c) 2025 APA, all rights reserved)
