Abstract(in English) Previous studies suggest that left-superior asymmetry in the brain activity reflects approach motivation of anger. As people gets upset, the asymmetry increases. Although much of evidence supporting this phenomenon has been demonstrated in terms of electroencephalographic (EEG) activity, it is unclear whether this asymmetry of brain activity is reflected in blood flow as evidenced by a near-infrared spectroscopy (NIRS). This asymmetry may be greater in elderly adults than in younger adults due to their weak inhibitory potential of frontal lobe. Here, we show that the elderly exhibited the left-superior brain activity (front-dorsolateral area) in a traffic jam created by a driving simulator, whereas the young adults did not. A slow down of the driving speed by an unknown car trouble did not yield asymmetric brain activity in the frontal lobe in both age groups. These results suggest that 1) a traffic jam produced asymmetric brain activity, which seems to reflect increased approach motivation (i.e., anger), 2) the NIRS scores reflected this asymmetric frontal brain activity, and 3) approach motivation (anger) was evidenced only by the elderly adults, suggesting vulnerability in inhibitory potential of aged adults.
