Experiment 1 investigated the occurrence of overselectivity by severely retarded youth within a match-to-sample paradigm. Temporal delay between offset of the sample item and onset of choice items was systematically manipulated. The multiple cue stimulus used was a picture with dimensions of color, shape, and border. Probe trials were designed to delineate the factors controlling responding. The results suggested that overselective responding occurs within the match-to-sample paradigm and is most evident with increasing delays between removal of the sample and presentation of choices. Subjects typically responded to only one dimension on probes designed to examine responding to individual dimensions of the compound stimulus. On other probes, however, subjects discriminated additional dimensions. This suggested that overselectivity may not be as restrictive as originally defined. Experiment 2 examined the effect of training individual dimension discriminations and training on different temporal delays within one match-to-sample task on the remediation of overselectivity in another match-to-sample task. Generalized remediation on probes which examined responding to individual dimensions clearly increased after subjects (a) were trained to separately discriminate the individual components of a multiple cue stimulus, and (b) had been taught this discrimination in the presence of a temporal delay. Overall, the present studies suggested that overselectivity may not be so restrictive as to preclude the learning of other dimensions but instead may occur within specific circumstances. |
