Event-related potentials and cognitive developmental behavior.

摘要

cope and method of study. This study investigated the relationship of cognitive developmental changes and physiological changes. Once cognitive developmental levels were assessed of 36 males, twelve each at the ages of 10, 11, and 12 years of age, event-related potentials (ERPs) were recorded during a visual "oddball" task. Cognitive developmental levels were assessed using Fischer's (1980) skill hierarchy as to their ability to derive a single abstract concept from the comparison of two concrete instances of that concept.;Findings and conclusions. Results showed that the amplitude of P300 was significantly greater for boys in Level 7 compared to Level 6 (p
