Abstract
The role of extrastriate cortical areas in selective attention was studied in 12 rhesus monkeys. Animals learned a series of color-form pattern discrimination problems, with either color or form cues relevant. After each problem was mastered, correct behavior required a shift in attention, i.e., that responses be made to the previously irrelevant dimension. On some problems shifting attention required that the animal maintain the same fixation; on other problems the color and form cues were separated in space, and the attention shift presumably required a shift in gaze. Matched groups of animals with inferotemporal, prestriate, or superior temporal sulcus lesions, and normal controls, differed significantly in their ability to shift attention. Analyses of inferred stages in attention shift showed that different processes were disturbed in the 3 lesion groups. Results are discussed in terms of cortical substrates for "looking" and "seeing.".This publication has 1 reference indexed in Scilit:
