Abstract
The relationship between reaction time and training result in the frequency discrimination tasks for inexperienced elderly subjects was assessed. The correct rate of task is commonly used as the measure of learning. In this paper, a reaction time is also used as the measure of learning. Subjects were divided into two groups to examine the influence of instruction. One is “instruction group” who are instructed to make a quick response during the task, the other is “non-instruction group” who are not instructed to make a quick response. The results demonstrated that 1) a simple reaction time for detection of sound stimuli became stable in about 50 trials, then training was considered to be completed in both groups; 2) A reaction time in training session reached a plateau in about 160 trials of training, and it was suggested that a reaction time could be applied as one of completion criteria of the response action training in instruction group. 3) Frequency difference limen were tend to improve gradually. Thus we needed a criterion of which threshold should be adopted. We proposed that the first threshold after training completed in instruction group should be adopted. It was suggested that this idea could be applied as one of decision criteria of the threshold.
