Forty toddlers, 1 1/2 to 3 1/2 years of age, and 8 adults, searched for stickers that were hidden underneath two discretely different classes of objects embedded in arrays containing several classes. Study results suggest that the children appear to have been attempting to determine which kinds of choices were the wrong ones. (Author/RWB)

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…

Assesses children's comprehension of "because" and "so" on enactment and sentence completion tasks. Results provide evidence against a componential model for the acquisition of causal connectives. Supported is the position that understanding of relational terms is initially context dependent; linguistic development generates…

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…

Examines the relation between attention to target and context information and target recall in an incidental learning task for children and adults. Results support a distinction between context-interactive and context-independent situations and suggest that the attentional patterns that are efficient for memory may differ with the kind of…
