VISUAL-VESTIBULAR INTERACTION AND THRESHOLD FOR ANGULAR ACCELERATION.

Abstract

Subjective response latencies from 36 Ss were used as an index of threshold across four intensities of angular acceleration (1.5, 3, 6, and 12 degrees/sec sq.) under three different visual conditions. These included total darkness (D), a simple, structured visual environment which rotated with S(LA), and a homogeneous, illuminated visual field (L). The results indicate that while illumination of the structured visual field lowers subjective threshold for angular acceleration, its differential effect is reduced with increased acceleration intensities. Visual field articulation enhances threshold sensitivity when compared with darkness, but not when L X LA comparisons are made. (Author)
