Neural Activity Underlying the Effect of Approach-Motivated Positive Affect on Narrowed Attention

Positive affects high in approach motivational intensity narrow attention. The present study extended this recent finding by testing whether a neural activation associated with approach-motivation intensity--relative left frontal-central activity--would underlie the effect of appetitive stimuli on narrowed attention (as measured by local attentional bias). It also tested whether individual differences in approach motivation relate to this attentional narrowing. Results supported predictions, suggesting a common association of relative left frontal hemispheric processing for approach-motivational processes and narrowed attention.
