On the relationship of frontal brain activity and anger: Examining the role of attitude toward anger

Activity in the left frontal cortex has been associated with positive affective traits, and activity in the right frontal cortex has been associated with negative affective traits. However, in this past research, the valence of the affect (positive vs. negative) was confounded with the direction of the motivation (approach vs. withdrawal). Recent research found that trait anger, a negative affect with approach tendencies, relates to increased left frontal activity. The present research addressed an alternative explanation for these past results--that the relationship between anger and increased left frontal activity is due to anger being regarded as a positive feeling. After developing a reliable and valid instrument that measures attitude toward anger, research indicated that trait anger related to relative left frontal activity and this relationship was not due to the anger being associated with a positive attitude toward anger.
