| Outline of Final Research Achievements |
In a series of studies, positive effects were shown in part of the reaction time results at the cognitive stage, but the effect of negativity bias was shown at the decision stage like young people.Therefore, it was revealed that the positive effect in the elderly occurs in the cognitive stage. From the viewpoint of the PFC activity, the blood flow increased with negative stimuli. Negative emotions that occurred in the limbic system including amygdala can be suppressed by activating the prefrontal cortex(Ochsner, et al., 2002). Therefore , it was revealed that positivity effect arises by suppressing discomfort for the elderly.
