I explain why attention is considered a selective process, the constructs of covert attention, spatial endogenous and exogenous attention, and feature-based attention. I explain how in the last 25 years research on attention has characterized the effects of covert attention on spatial filters and how attention influences the selection of stimuli of interest. This review includes the effects of spatial attention on discriminability and appearance in tasks mediated by contrast sensitivity and spatial resolution; the effects of feature-based attention on basic visual processes, and a comparison of the...  Highlights: ► This review on visual attention focuses on research conducted the last 25 years on the effects of spatial and feature-based covert attention on visual perception. The review considers attention as a selective process, and includes psychophysical, electrophysiological, neuroimaging and computational studies.
