Event Abstract Back to Event Influences of mood valence and arousal on the breadth of visual attentional focus: An ERP study Hiroki Moriya1* and Hiroshi Nittono1 1 Hiroshima University, Graduate School of Integrated Arts and Sciences, Japan Aims: Affective states are thought to modulate the breadth of attention, with positive moods broadening and negative moods narrowing visual attentional focus. Although traditional research addressing the effects of moods on the breadth of attention has emphasized the effects of affective valence (i.e., pleasant vs. unpleasant), the role of arousal associated with moods has remained unclear. In this study, we examined the effects of both mood valence and mood arousal on the breadth of attentional focus by using event-related potentials (ERPs). Method: Twenty-four students performed a flanker task under high-arousal positive, high-arousal negative, low-arousal positive, and low-arousal negative moods, which were induced by music and imagery. Simultaneously with the flanker task stimuli, a white rectangle ‘probe’ stimulus was presented at one of four locations (inner probes: 0.5 degrees left or right from the central letter, outer probes: 1.5 degrees left or right from the central letter). The amplitudes of P1 (95-105 ms post-stimulus) and N1 (140-160 ms post-stimulus) in response to the probe stimulus were used as indices of the amount of attention allocated to a particular position. Results: Subjective affective ratings confirmed that the mood-induction procedures effectively produced the target moods. The amplitudes of P1 and N1 were larger for inner probes than for outer probes, indicating that attention was focused on the central letter. This probe position effect was smaller under positive moods than under negative moods. Moreover, the effect was reduced and became statistically non-significant in the low-arousal positive moods. Conclusions: Positive moods broaden attentional focus at the early sensory input stages, in comparison to negative moods. This effect is most prominent when mood arousal is low. Our results suggest that the effect of positive moods on breadth of attention is modulated by mood arousal.
