The effects of an individual difference in executive attention on suppression function of behavior and thought

要旨

The present study investigated the association between individual differences in executive attention and the suppression of behavior and thought by measuring Effortful Control (EC). A negative association between EC and the commission of errors in the Go/No-go task, and thought intrusion in the thought suppression task were found, which indicated that the lower EC score an individual has, the worse performance he showed in each task. A low performance in the Go/No-go task suggested that an individual with a low EC would show hyperactivity in the anterior cingulate gyrus, and malfunction in the orbitofrontal cortex. Additionally, the result in the thought suppression task in this study revealed that measuring EC could predict the frequency of thought intrusion.
