[Event-related potentials of emotional excitement in middle-aged and aged adults].
OBJECTIVE
To explore how adjustment of the negative and neutral emotion excitement contribute to the well-being of middle-aged and aged adults in their health, intelligence, working and living.


METHODS
Twenty-five middle-aged and aged participants performed recognition tasks of schematic facial representations of positive, neutral and negative emotions and also Chinese characters (equivalent to happy, thinking and fear).


RESULTS
The main effects of the facial recognition task occurred in the left temporal-parietal area (40 to 80 ms), bilateral parietal-occipital and temporal-parietal area (160-180 ms and 310-340 ms). The effects of stimulation with the 3 Chinese characters were found in the anterior region (375-475 ms), posterior region (195-255 ms), and whole scalp region (135-175 ms and 275-355 ms). There were no significant interactive effects between schematic facial recognition and stimulation with Chinese characters.


CONCLUSIONS
Positive emotional excitement may promote the well-being of the adults in their health, intelligence, working performance and living.
