| Research Abstract |
The present study aimed to investigate the evolutionary origin of abilities of categorization in humans. In Study 1, eight chimpanzees participated in a category choice task to investigate the effect of typicality. In Study 2 with a symbolic matching-to-sample task, only one of the six chimpanzees reached the learning criterion after two years of training phase. The juvenile chimpanzee that learned symbolic relations participated in the following tasks to examine cognitive processes of symbols. The results suggest that extraction of a semantic attribute from the symbol might help retention of the memory in the chimpanzee.
