Abstract
|
|
|
The reaction time tests were thought to be relatively simple and sensitive tools to evaluate the level of arousal and concentration. The purpose of the study was to investigate the normative data of simple reaction time test in Korean people.
60 normal subjects in 3 age groups were tested on visual and auditory reaction times. Mean reaction time was 258 msec in visual reaction time test and 234 msec in auditory reaction time test. Mean reaction times were prolonged in older age group.
False
key rates (errorness key pressing in the absent of target stimuli) were 0.005 in visual reactio time test and 0 in auditory reaction time test. Missing key rates(no response for above 2 seconds since target stimuli start) were 0.002 in visual
reaction
time test and 0.002 in auditory reaction time test.
It was concluded that the reaction time test is simple to conduct in clinical setting and error rates can also be used as evaluative indices.
