Groups of second grade and college students were presented with a series of three-alternative, four-dimensional discrimination problems that contained probes for the subject's hypothesis. Subjects received either complete feedback or partial feedback. In the latter condition, when subjects were told their response choice was incorrect the correct…

These results provide a more precise attentional interpretation of both preference and pretraining effects. (Authors)

Results indicate that for children in this study's age range orientation is a less salient discriminative cue than either size or color. (Author/MB)

Analysis of 40 first-grade children's performance on two discrimination learning problems revealed that children do transfer dimensional information between the visual and tactual modalities. (Author/JMB)

Subjects were trained against their initial dimensional preference in a two-dimensional simultaneous discrimination learning task. (RH)

A single administration of the reversal learning paradigm is not a sufficient basis for determining either a given subject's choice of option or his behavior on its constituent learning measures. This conclusion raises many questions about past research relating to mediation theory, since this paradigm has been the basic one employed. (Authors)

Describes two experiments conducted to explain why retarded children of younger mental age appear to be more selective on discrimination tasks containing relevant redundant cues than do children of older mental age. Findings are consistent with the hypothesis that the latter group of children are overselective because they tend to solve…
