The effect of stimulus prefamiliarization on children's discrimination learning was investigated. Kindergartners were prefamiliarized with pictures which were identical, similar, or unrelated to pictures used in the learning task. Consistent with predictions derived from previous research, the learning of subjects who were prefamiliarized with…

Three studies involving groups of four- to five-year-old children examined whether the discriminative properties of prompts are critical for establishing a difficult (septagon, octagon) discrimination through time delay. Results confirm superiority of multiple-stimulus, distinctive-feature prompts, implying that stimulus dimensions of prompts are…

Investigates to what extent discrimination learning through time delay of multistimulus, distinctive-feature prompts is a function of the inclusion and configuration of the S-prompt. Results of two experiments with children aged four and five indicate that most subjects did not learn the task assigned unless two distinctive-feature prompts were…
