The purpose of the present study was to elucidate an anxiolytic drug effects on reminiscence by mirror drawing test and a sequential optimum selection plan with Play-the-Winner sampling and the stopping rules in a finite population in this experiment.<BR>The subjects were thirty healthy volunteers of junior college women. They were tried on mirror drawing test, two three-minute work periods being separated by a forty-minute rest pause. After the first work period, one group was given a tablet of ID-540 0.5 mg and the other group, a placebo by double blind method. The tests were repeated 15 times for the respective pairs drawn from both groups.<BR>As the results, reminiscence was not found out the drug-group but for the placebo-group, so that the effect of dissociation of learnig was found in anxiolytic drug.<BR>In the veiw of such a decision procedure, an extensive Play-the-Winner Sam pling Rule, with a successive success stopping rule, was proposed to select the stronger of two treatments on the drug effects in the ethical sence, which gave us the minimum expected loss in a finite population.
