Description
Summary:Theories suggest that positive affect broadens attention, whereas negative affect focuses attention. This position has been supported by studies showing that positive affect leads to more diffuse spatial attention while negative affect leads to more focused spatial attention. Recently, researchers have used the attentional blink (AB) paradigm to show that induced positive affect may also lead to more diffuse temporal attention, allowing greater accuracy for targets presented within a short time interval. The present study investigated whether dispositional affect could modulate temporal attentional diffusion using the AB paradigm. Consistent with the diffusion hypothesis, greater positive affect was associated with smaller AB magnitude, whereas greater negative affect was associated with larger AB magnitude. Thus, dispositional affect can modulate the costs of attentional selection over brief time intervals.
