This article reviews a particular computational modeling approach to the study of psychological development--that of constructive neural networks. This approach is applied to a variety of developmental domains and issues, including Piagetian tasks, shift learning, language acquisition, number comparison, habituation of visual attention, concept…

Presents some additional comments from the current authors regarding their original article Interpolation processes in object perception: Reply to Anderson (2007). As this exchange concludes, we believe that the account of interpolation and object formation proposed by Kellman and Shipley (1991), further developed in recent years (Kellman, 2003;…

Noting the current push for rigor in secondary school curriculums (the lead member of the "new three Rs" of rigor, relevance, and relationships), Washor and Mojkowksi take a closer look at the prevailing conception of rigor. They argue that a narrowly defining a rigorous curriculum as one with more advanced courses and more factual content…

Five investigations examined three- and four-year olds' conceptions of the relationship between pictures and their referents. Results indicated that preschool children have difficulty holding in mind the distinct properties of picture and real referent, just as they tend to confuse the literal and intended meanings of utterances.

This study examined the relationship between convergent and divergent thinking and performance errors in reversal and nonreversal concept tasks. The results show: (1) a positive relationship between convergent performance and concept errors; and (2) an inverse relationship between divergent performance and concept errors. These correlational…

The purpose of this study was to investigate the effects of hypothesis testing instructions compared to brief instructions on the speed of shift problem solution of grade school age subjects, in order to provide information on the development of hypothesis testing behavior in children and the sampling characteristics of hypothesis testing in these…

Three experiments are reported that were designed to test the effectiveness of two training procedures, one perceptual, the other verbal, on upgrading the conceptual behavior of preschool children. (Authors/MB)

Noting that children who can easily categorize a picture in terms of what it depicts may have difficulty understanding the picture as a representation or thing in itself, four experiments with children around four years old examined their responses to pictures as things in themselves. Results showed that some children had difficulty understanding…

Studies of the ability of elderly debilitated patients to respond to conceptual training and their differential response to different kinds of conceptual shifts. (Authors/MB)

Results showed that reversal shift was easier than extradimensional shift and that relative shift difficulty was unaffected by instructions, in contrast to findings with college-age subjects. (Authors)

Examines the importance of (1) dimensional characteristics of stimuli present in discrimination transfer tasks, (2) having contrasting stimuli presented simultaneously, and (3) subjects age. Subjects were rural Mexican youths, ages 4 to 10. Reversal and nonreversal type discrimination transfer problems were used in the study. (DP)

Presolution reversal prevented or significantly retarded learning in kindergarten and first-grade children but did not hinder learning in fifth-grade children. (Authors)

The ability of children of 3-5 years to acquire mediated solutions to conceptual problems and to execute rapid reversal shifts within these concepts suggests that their problem solving capacity is not necessarily limited to simple associative responses. (Authors)

Learning behavior of young children of contrasting socioeconomic backgrounds is examined in this study, which poses the question: what are the necessary or sufficient environmental conditions for the establishment of identifiable patterns of behavior? Socioeconomic level (SEL), the principal independent variable, was defined in terms of parental…
