SOUZA, Carlos Barbosa Alves de et al. Generalized identity tests with objects in capuchin monkeys (Cebus apella). Psic.: Teor. e Pesq. [online]. 2009, vol.25, n.2, pp.169-177. ISSN 0102-3772.

Capuchin monkeys show generalized identity (GI) when tests are preceded by repeated shifts of simple discrimination training (RSSD) with stimuli used in tests. The present study evaluated if that facilitating effect of RSSD training could be due exclusively to the previous contact with the testing stimuli. It was given to a male capuchin monkey four GI tests with objects: Test 1 - an identity conditional discrimination task with new stimuli; Test 2 - with the same stimuli used in Test 1 after RSSD training to induce conditional control; Test 3 - with new stimuli, freely manipulated by the subject previously; and Test 4 - with the same stimuli used in Test 3 after RSSD training. The subject's performance reached the learning criterion in Tests 2 and 4. RSSD training was more effective than free manipulation to produce immediate matching to sample with new stimuli.

Palabras clave : generalized identity; simple discrimination; conditional discrimination; capuchin monkey.
