Abstract
A major function of the human prefrontal cortex is inhibition of the ongoing reaction tendency for adaptation to changing environments. The go/no-go task is a representative method of investigating this inhibitory function. This study was carried out at 4-night-5-day and 30-night-31-day summer camps and investigated the responses to go/no-go tasks during pre- and post-camp periods. The findings showed that the numbers of errors in the no-go tasks decreased significantly at both camps, suggesting the possibility that the inhibitory function of subjects improved through the camp experience.
