In this study 56 prekindergarten and 174 kindergarten children learned to choose either the card with more or the card with fewer elements in simultaneous discrimination problems. Learning was faster when the card with more elements was positive, particularly when a zero-element card was involved. (Author/SB)

Tests were made of the effects of conceptual associations among words, a type of associative relationship not previously manipulated, on verbal discrimination learning. (Editor)

The major question addressed in the present article was whether frequency experienced through a natural language activity, such as reading textual material, influences subsequent verbal discrimination (VD) learning in the same manner as that which has been demonstrated for other types of familiarization, e.g., free-recall learning - Underwood &…

Thirty-six retarded and 36 nonretarded children and adolescents, individually matched for mental age, were given discrimination problems at two levels of stimulus complexity to test the hypothesis that retarded persons require more trials to reach criterion on the more complex problems. (Author)

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

There should be a meaningful discussion on the importance of awareness of group sensitivities if children are to be worked with effectively. It is obvious that social consciousness is changing radically in these volatile times. This article reviews some of the significant changes. (Author/NH)

Results indicate that dimensional shifting represents some form of nonverbally mediated learning rather than a more limited form of discrimination learning bound to the specific sensory modality of training. (MH)
