Stimulus factors effecting peer conversation among institutionalized retarded women.

The effect of a series of stimulus changes, including attendant present or absent and agent of token reinforcement in a sorting task, on peer interaction among retarded women was examined. Conversation was not differentially directed toward the agent of reinforcement when that agent was a peer, nor did a peer agent increase the overall rate of peer interaction. Peer interaction did increase when no attendant was present, and during the final phase of the experiment, the high rate of peer interaction was maintained while the attendant was faded back into the situation in a series of discrete steps. The procedure was found to be efficient in terms of staff time and did not adversely affect task performance.

The effect of intermittent feedback and intermittent contingent access to play on printing of kindergarten children.

Intermittent grading of papers and the combination of intermittent grading with contingent access to play were evaluated as methods for increasing the accuracy of kindergarten children's printing responses. For a group of target letters, intermittent grading alone failed to produce an increase in accuracy, but when grading was paired with access to play, accuracy increased for every child. These results were then replicated with another letter.

Operant training and generalization of a verbal response form in a speech-deficient child.

A subject who spoke essentially in "telegraphic" English, leaving out most articles and auxiliary verbs, was trained to use a particular sentence form that included the articles and verbs to describe a set of standardized pictures. The subject used the trained sentence form to describe the trained pictures, and in addition, use of the sentence form generalized to sets of untrained and novel stimuli. When the trained sentence form was changed, the subject used the new form to describe both training and generalization stimuli. When the original correct form of response was retrained, the subject once again used the trained sentence form to respond to both training and generalization trials.
