| Abstract: | Until a few years ago, visual search tasks were of exclusive pertinence to psychophysicists and cognitive psychologists trying
to understand the operating principles and computational constraints of visual perception and visual selective attention.
In recent years, cognitive neuroscience, with its powerful tools, has started to explore more directly the neuronal mechanisms
underlying search performance in humans and macaques, aiming at the same general goals. New observations from a number of
cognitive neuroscience approaches are promising a near future of great excitement in this field of research. This article
offers a critical review of some of these recent contributions and highlights some of the interpretational problems that they
pose.
