摘要
An experiment was carried out to assess the ability of captive western lowland gorillas (Gorilla g. gorilla) to exchange objects with a human partner. Before the exchange itself, individuals had to learn to give an item to the experimenter. Four individuals out of nine performed active giving. After that familiarization with giving behaviour, two kinds of exchanges, of increasing complexity, were tested with gorillas. Simple exchange (give C to obtain D) was the first procedure and six gorillas out of nine succeeded. Double exchange (give B to receive C, then give back C to obtain D) was performed only by three individuals and triple exchange (give A to receive B, give back B to receive C, then give back C to obtain D) was performed only by two individuals. Different types of errors were scored, as well as social constraints on learning. Results showed that (1) naive gorillas are able to geta reward (D) in an experimental exchange situation; and (2) the complex rules of multiple successive exchanges were not easily understood by gorillas.
