摘要: Chimpanzee cognition has been studied predominantly through the visual modality, and much less auditory modality. The aim of this study was to explore possible differences in chimpanzees' processing stimuli. We developed a new conditional position discrimination (CPD) task requiring association between stimulus (from either or modality), spatial (left right). stimuli consisted face voice two individuals well known subjects (one chimpanzee one human). Six chimpanzees participated both conditions. found contrasting results conditions: acquired CPD more easily than condition. This supports previous findings on difficulties encountered by learning tasks involving Our experiments also revealed individual differences: with most extensive experience symbolic matching showed good performance In contrast, expert an auditory-visual intermodal no sign Future work should focus finding appropriate procedure for exploring cognitive skills.
