CMB Monday Seminar (Attention)- Risa Sawaki

Cognitive Mechanisms Underlying Modulation of Distractor Processing by Spatial Attention Salient distractors often capture our attention, even when they are irrelevant to ongoing activity. The findings of previous studies have led to diametrically opposed interpretations with respect to the nature of attentional capture. One suggests that attentional capture is a stimulus-driven, bottom-up phenomenon that is determined exclusively by the saliency of visual objects, whereas the other implies that top-down attentional set plays an important role in the control of attentional capture. We are investigating whether spatial attention is strongly associated with the bottom-up and top-down mechanisms of attentional capture. I will talk about the current experiment examining how target-similar and salient distractors are processed inside and outside attended zones of visual space.
