This study examined the relationship between reaction time (RT) and intelligence. Fifteen female and nine male caucasian undergraduates and one black male undergraduate ranging in age from 19 to 38 served as subjects. The measure of intelligence was the Otis-Quick Scoring Mental Ability Test. An Apple MacIntosh personal computer was used to present stimuli and measure reaction time. There were four RT conditions; simple reaction time, and three complex conditions in which no cue appeared, a correct cue, or an incorrect cue appeared. A significant correlation was found between the correct cue/no cue difference score (r = {dollar}-{dollar}.43, p {dollar}\u3c{dollar}.05)
