Description

We tested whether motivational dispositions (BIS/BAS measure) predict attention to negative stimuli and whether frontal alpha asymmetry (FAA) moderates these effects. Twenty adults completed an eye-tracking task viewing negative IAPS images; fixations within the image’s most aversive region in the first second indexed vigilance. Higher BIS predicted greater fixation percentage. Moderation showed BIS predicted greater engagement under left-frontal activation. Findings implicate FAA as a marker of vigilance.
