Separating emotion and motivational direction in fear and anger: effects on frontal asymmetry.
Full Abstract
State effects on frontal alpha electroencephalograph asymmetry (ASY) are thought to reflect approach and withdrawal motivational tendencies. Although this motivational direction model has inspired a large body of research, efforts to disentangle influences of emotion (EMO) and motivational direction (MOT) on ASY are rare. The authors independently manipulated EMO (fear and anger) and MOT (approach and withdrawal) in a between-subjects design. Irrespective of MOT, anger led to greater changes toward relative left frontal activation (LFA) than did fear. Conversely, higher ratings of negative valence were associated with greater changes toward LFA in withdrawal but with greater changes toward relative right frontal activation in approach. Results are discussed within a model based on behavioral inhibition system-behavioral activation system theory.
