With a ride on a ferris wheel as an anxiety-provoking situation, Ss were given meprobamate (1600 mg.) and placebo in an a-b, b-a administration. Measures of anxiety were obtained, viz., a direct measure of automatic activity (palmar sweat), an indirect measure of autonomic N.S. activity (reports re: upset stomach, increased heart rate, nervousness, hand tremulation, dizziness, cold sweat), and reports of degree of fear experienced. Meprobamate apparently did not lead to a significant reduction in the symptoms of anxiety. (PsycINFO Database Record (c) 2006 APA, all rights reserved)
