Prompt Response

It was hypothesized that systematic visual-color consequences contingent upon verbalizations would be effective in augmenting the rate of sounds as well as shaping specific words and word approximations, in a six-yr.-old autistic child. It was found that verbalizations were augmented over a base rate in a free operant situation. However, in a prompt-response contingency food was significantly more powerful in shaping specific sounds. Reasons for the difference were discussed.

Free Operant Situation

Rats were trained on a single-stimulus, successive discrimination in a free operant situation. An irrelevant stimulus dimension was present at ail times. Following attainment of the acquisition criterion, Ss were shifted immediately or given 4 or 8 days of overtraining before being shifted. Half of Ss were given a reversal shift and half a nonreversal shift. Overtraining did not affect reversal or nonreversal learning. These results were contrasted with those of Mackintosh (1962). Various theoretical issues were discussed in light of the present findings. It was tentatively concluded that the overtraining effect depends upon the role of observing behavior in the formation and overtraining of a discrimination.

Free Operant Situation

The effects of five levels of training (210, 490, 1470, 2450, 3430 reinforced responses) on extinction performance were investigated. A free-operant bar-press paradigm was employed. A continuous reinforcement schedule was used with .12 ml. of 64% sucrose. Number of bar-presses and duration of time to reach a 1-min. non-response criterion showed that resistance to extinction was an increasing function of the number of reinforcements during training. However, the amount of time required to reach a 5-min. criterion showed the opposite relationship. It was concluded that different criteria reflected different patterns of extinction behavior and that the overtraining extinction effect (decreased resistance to extinction following extended training) could be demonstrated in a free-operant situation if the appropriate criteria were selected.

Free Operant Situation

Rats were trained on a single-stimulus, successive discrimination in a free operant situation with continuous reinforcement of responding to S+. Ss were given 0, 4, or 8 days of overtraining (OT) after reaching the discrimination criterion. Half of the Ss were given a reversal shift (RS) and half a nonreversal shift (NRS). An irrelevant stimulus dimension was present at all times in Exp. 1, and it was absent in Exp. 2. OT did not affect RS or NRS learning in either experiment. NRS learning was faster than RS learning. These results were contrasted with other studies which have reported that OT facilitated RS learning and impeded NRS learning. Certain theoretical interpretations of discrimination learning, particularly Sutherland's treatment of centrally mediated attentional mechanisms, were critically discussed in light of the present findings.
