ASSESSMENT OF SEMICIRCULAR CANAL FUNCTION: 1. MEASUREMENTS OF SUBJECTIVE EFFECTS PRODUCED BY TRIANGULAR WAVEFORMS OF ANGULAR VELOCITY,

Abstract

Two methods were compared for measuring subjective angular displacement produced by triangular waveforms of angular velocity while subjects (N = 11) were enclosed in a vertical-axis rotation device that excluded visual and auditory cues of angular motion. Accuracy of subjective estimates was influenced by the methods and by the magnitudes of the acceleration comprising the stimulus waveforms. Results suggest that one of the methods, with slight modification, will provide reliable indication of the subjective effects of controlled semicircular canal stimulation. (Author)
