The present study aimed to explore the response bias pattern, discriminability, and reaction time of boys with and without attention deficit hyperactivity tendency by the differences in reward amount. Sixty subjects from 9 to 12 years of age were divided into two groups, 28 for attention deficit hyperactivity tendency and 32 for control group, according to Conners' abbreviated teacher rating scale. They were asked to identify Wisconsin Card sorting Test by form and number stimulus. Half of each group received reward differently. Half of Each group were rewarded 3 times much more when they identified form successfully and the others did number stimulus. Control group showed significant response bias toward more rewarded stimulus than attention deficit hyperactivity tendency group did. These findings suggest that children with attention deficit hyperactivity tendency are less sensitive to toward and their behavior isn't controlled by indwelling information of reward possibility, but immediate contingencies. The limitations and implications of this study were discussed.
