| Abstract | Studies of selective attention suggest a system which operates across modalities and on many forms of internal representation. Complex analysis, even semantic analysis, of sensory input may occur automatically, but attention controls the locus of action. When computations carried out by the brain are effortful, in the sense that elements compete for a common resource limited in capacity, psychologists label them as requiring attention. Such computations are often carried out serially. Processes in which activities are carried out simultaneously without interfering with one another are said to be automatic. Attention may be summoned to a particular spatial location by the presentation of a visual cue. The operation of two posterior brain systems may be involved in the selective attention: the superior colliculus for the selection of spatial location and the dorsolateral prefrontal cortex for the selection of semantic information. Investigation of spatial attention within the visual system provides a means to explore the neural systems involved in the control of attention. (JAZ) |
