Visual attention and inferotemporal cortex in rhesus monkeys

Abstract Four rhesus monkeys with inferotemporal lesions were inferior to their normal controls in relearning a visual discrimination problem with variable, irrelevant cues, and in shifting responses to the previously irrelevant cues. Reducing the variability and/or amount of information improved the performance of the inferotemporal group. Results are interpreted in terms of a “trade-off” model of visual attention.
