Abstract : Three chimpanzees, two males and one female, 92 to 104 months of age, were taught a visual match-the-sample task consisting of 24 problems. Following the demonstration that these subjects could memorize the rewarded stimulus in each of 24 configurations, each consisting of four stimuli, the subjects' ability to continue to respond to the rewarded stimuli with one stimulus to two stimuli missing from each configuration was tested. The results demonstrated that the chimpanzee can successfully respond to visual stimulus and configurations that no longer contain all components on which the subject was originally trained. These results are discussed in terms of the amount and kind (i.e., rewarded vs. non-rewarded stimuli) of information required by the chimpanzee for the solution of a visual discrimination task, redintegration in the chimpanzee, and the cognitive capacity of the chimpanzee.
