Learning and transfer of oddity as a function of apparatus and trials per problem

  • Paschal N. StrongJr.
Animal Behavior


Fourteen naive Rhesus monkeys were trained on one of three apparatus (The Wisconsin General Test Apparatus, the Primate Automatic Test Apparatus-Key, and the Primate Automatic Test Apparatus-Lever). The problem to be learned was a 6-trial or 1-trial, two position, oddity problem. Six-trial animals were switched to the 1-trial problemupon reaching criterion. Upon attaining the 1-trial criterion, a test series of novel problems was presented to each animal. Twelve of the 14 animals were then transferred to a new apparatus and again learned the oddity problem. The following were concluded: (1) Animals appear to learn as well with two dimensional stimuli as with three dimensional. (2) Animals reach criterion on 1-trial problems as soon as 6-trial problems. (3) Six-trial animals require a significant number of additional trials to reach the 1-trial criterion. (4) When an animal is transferred to a new apparatus and given the same oddity problems, there is no evidence of any positive transfer.
