Abstract

Using event-related potential (P300 and CNV), the cognitive function of elderly was compared with that of young subjects. It was found that the prolonged cognitive information processing induced by aging effects was reflected in P300 and N400 latency. The aging effect was not observed in P300 amplitudes. The CNV measurements, in the range of this study, did not reflect the aging effect. This might be because the CNV reflects a higher cognitive function as compared with P300, and the aging effects do not appear in such an aspect. The data also suggested that such factors as character, eating habit, exercise habit, life style, cognitive style, cognitive drive, and job(or occupational) history must be taken into account when evaluating the deterioration of cognitive functions with aging.
