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