| summary | Traditionally, several pieces of evidence have been used to argue for the primary role of bottom-up saliency in visual selection, including search asymmetries, visual grouping effects and pop-out effects. I will present recent evidence that, in each of these instances, processing can be modulated by top-down knowledge - either the 'template' of the target or particular items held in working memory. Neuropsychological studies with patients showing extinction further show that the match between bottom-up information and information held in working memory enables a stimulus to pass into conscious awareness. |
