Anne Treisman Lecture with Dr Marisa Carrasco (New York University)

Visual attention is essential for visual perception. Spatial attention allows us to grant priority in processing and selectively process information at a given location.
In this talk, Marisa Carrasco presents: (1) psychophysical experiments investigating how endogenous (voluntary) and exogenous (involuntary) covert attention alter tasks mediated by basic visual dimensions as well as their featural representations; (2) neuroimaging (fMRI) experiments differentiating effects of endogenous and exogenous attention on occipital cortex; (3) neurostimulation experiments establishing that transcranial magnetic stimulation (TMS) on occipital cortex extinguishes the effects of exogenous attention but not those of endogenous attention. Together these studies reveal how endogenous and exogenous attention shape perception by altering the processing of basic visual dimensions.
