摘要: Event-related potentials and reaction time (RT) were recorded concurrently during the performance of six simple cognitive tasks for subjects (N = 30) who varied in mental ability. P300 latency to target stimulus increased with increasing task difficulty same manner as RT on these tasks. was inversely related ability, particularly more difficult paired-stimuli The first unrotated factor extracted from intercorrelation stimuli defined a general that accounted 41% variance. scores intelligence scores, (−.36, p < .05). relationship between distinguished movement time, negligible. These results suggest may assess stimulus-evaluation response-production components information processing, respectively, vary intelligence.
