Tested the hypothesis that retarded children will increase their recall organization after semantic strategy training and that they will generalize their organizational behavior when given novel categories to learn. (Author/DB)

Assesses the relative effects of manipulation of antecedent stimulus conditions and subsequent reinforcement contingencies on imitative and nonimitative behavior. Fading (a form of antecedent conditions manipulation) was highly effective in establishing stimulus control of imitative and non imitative responding. Reinforcement of non imitative…

When taught to link sorting to self-instruction ("I'm looking for blue triangles") children show perfect accuracy in sorting. This study investigated if this performance would generalize to new stimuli. One participant showed near-perfect generalization to all new stimulus sets (shapes, letters, pictures); two had difficulty with…

Investigated degree to which two shape dimensions were represented categorically by children and adults when learning object names. Found that adults accepted names more often to objects that fell within proposed shape boundaries than to objects that crossed boundaries. Children were just as likely to generalize names to novel objects that fell…
