Abstract
3 groups of retardates were trained on a 2 choice simultaneous discrimination. Discriminanda were pieces of candy differing in color and form. Each of 2 pieces was mounted on a gray wedge and enclosed by a transparent cover. Ss had to remove the wedges from foodwells, one of which was baited with a candy-reward identical in color and form to either the positive cue (Group P), the negative cue (Group N), or dissimilar to both cues (Group C). Discriminative performance of Group P surpassed that of Groups C and N, and Group C was superior to Group N. This finding suggests that approach tendencies to candy-rewards transfer, (through common stimulus elements), to choice-point candy-cues, facilitating or impairing discrimination.
