Description
Summary:People often inhibit or override their dominant response tendencies in order to complete tasks successfully. Exerting such self-control has been shown to influence attentional breadth differently depending on approach-motivated tendencies, as indexed by individuals’ behavioral activation system (BAS) scores. Approach motivation and attentional breadth have previously been associated with frontal alpha asymmetry (i.e., lateralized cortical activity in the frontal regions) where greater left-frontal activation is associated with greater approach motivation and reduced attentional breadth. The process model of self-control posits that exercising self-control leads to a subsequent increase in approach behavior in high BAS individuals, and this could be due to a shift towards left-hemisphere-frontal processing. This was the first study to examine both frontal asymmetry and attentional breadth before and after exercising self-control in low and high BAS individuals. Greater BAS, and greater difficulty exercising self-control, both positively related to more narrowed attentional breadth after completing the manipulation relative to before, but only after exercising self-control. However, breadth of attention and changes in attentional breadth were unrelated to frontal asymmetry, suggesting that the influence of self-control on individuals’ attentional breadth was not due to changes in frontal activation patterns.
