Summary
Eight male subjects were studied during a five-hour period following a single dose of 0.55 g alcohol per kg body weight. The main variables of the experiment were: (a) blood alcohol concentration, (b) self-estimated degree of intoxication, and (c) observed degree of intoxication. The subjective scales were obtained by the method of magnitude estimation. The two curves representing self-estimated and observed degree of intoxication were in very close agreement; in a general way they also followed the blood alcohol concentration curve, although certain systematic deviations were found. In addition, (d) self-estimates of certain mood variables were obtained, and (e) two objective performance tests were administered. Nearly all curves obtained in the experiment showed a peak about 30-40 minutes after alcohol intake. The subjective variables appeared to be more affected by alcohol than the performance variables.
