Matching visual stimuli on the basis of global and local features by chimpanzees (Pan troglodytes) and rhesus monkeys (Macaca mulatta)

摘要: This study was designed to examine whether chimpanzees and monkeys exhibit a global-to-local precedence in the processing of hierarchically organized compound stimuli, as has been reported for humans. Subjects were tested using sequential matching-to-sample paradigm stimuli that differed on basis their global configuration or local elements, both perceptual attributes. Although species able discriminate exhibited strategy, whereas rhesus local-to-global strategy. The results suggest attentional mechanisms underlying information-processing strategies may account differences learning by primates.
