Individuals with high anxiety have the cognitive biases in the executive control function. The Wisconsin Card Sorting Test (WCST) is a cognitive task based on the neuropsychological theory that measures executive control processing. In this study, we examined whether high anxious individuals show a dysfunction in the executive control processing. Twenty university students were assigned to either the high anxious group (HAG) or low anxious group (LAG). All participants completed the computerized version of the WCST. A t test was conducted with the score of "categories achieved (CA)", "numbers of response cards until the first category achieved (NUCA)", and "total errors (TE)". Results showed that HAG scored significantly lower on CA (t(18)= 3.55), higher on NUCA (t(18)= 3.25) and TE (t(18)= 5.00) than to LAG (ps<.01). The findings suggest that anxious people tend to have low executive control, making adaptive processing in daily life difficult.
