Abstract : To determine if a particular head position results in maximal response to stimulation, 50 subjects were tested with sinusoidal acceleration in three head positions with reference to the horizontal plane. A PDP-11/34 digital computer was used to analyze the responses. The pertinent parameters were gain, phase, and directional preponderance. The results showed no difference in the parameters for the three head positions. This suggests that positioning a subject's head for rotational testing is not as critical as previously believed.
