This research investigated the shape of the acquisition and reversal functions in retardates' discrimination learning, with safeguards against suspected artifacts in other studies. A modified Wisconsin General Test Apparatus was used with 60 retardates in a 2 × 2 factorial design. Another 11 were classified as pseudolearners. The variables were the prereversal criteria and the number of irrelevant dimensions. After meeting criterion subjects were given 30 more trials for the detection of pseudolearners, but all received reversal training. Performance was stationary in both acquisition and reversal, suggesting all-or-none learning. For learners, differences of midreversal plateaus appeared which were opposite to predictions of the Zeaman and House (1963) theory. When pseudolearners were included, however, the plateau effect partially conformed to the theory.

The Subject

Color preference was tested by showing 6 colored objects to one adult gibbon. The subject demonstrated both color and position preferences on a modified Wisconsin General Test Apparatus. The blue object and, during some conditions, responses to the subject's right were most preferred.

General Test

Dominance competition between paired rhesus monkeys ( ns = 4) was compared using a standard apparatus, the Wisconsin General Test Apparatus, and a new device called the Parallel Competition Box. The Parallel Competition Box does not allow physical contact between individual Ss during testing as does the Wisconsin General Test Apparatus. Results comparing the Parallel Competition Box and the Wisconsin General Test Apparatus on food incentive competition indicate that physical contact is not necessary for assertion and maintenance of dominance between socialized rhesus monkeys.

Size Stimulus

18 dogs ( basenjis) were tested on 3 consecutive intermediate size-discrimination and transposition problems in a modified Wisconsin General Test Apparatus (WGTA). Solution of the discriminative task required significantly fewer trials across successive problems. Dogs generally responded to the absolute size of the stimulus. However, (a) delayed or repeated testing or (b) tests in the direction of the animal's original size preference facilitated responses to the relative middle-size stimulus.
