Children's knowledge of the ordinal relations among number symbols is related to their mathematical learning. Ordinal knowledge has been measured using judgment (i.e., decide whether a sequence of three digits is in order) and ordering tasks (i.e., order three digits from smallest to largest). However, the question remains whether performance on…

This study examined the unfolding in real time of original ideas during divergent thinking (DT) in five- to six-year-olds and related individual differences in DT to executive functions (EFs). The Alternative Uses Task was administered with verbal prompts that encouraged children to report on their thinking processes while generating uses for…

"Patterning" is a cognitive intervention that is unknown to psychologists, but has nevertheless been taught for half a century in nearly all kindergartens and many preschools in English-speaking countries. Patterning is the understanding that a certain rule governs the sequence of items in a series. At the simplest level, if the series…

Counterfactual thinking refers to imaginative thoughts about what might have been ("if only" or "what if") which are intrinsically linked to self-conscious emotions (regret and guilt) and social judgements (blame). Research in adults suggests that the focus of these thoughts is influenced by order (temporal and causal). Little…

In transparent orthographies like German, isolated learning disabilities in either reading or spelling are common and occur as often as a combined reading and spelling disability. However, most issues surrounding the cognitive causes of these isolated or combined literacy difficulties are yet unresolved. Recently, working memory dysfunctions have…

Study concerned with the mechanisms in terms of which the developmental transformation from one cognitive structure to another occurs. (Author)

Study attempted to specify two complementary aspects of children's inferential size judgments within the context of Piaget's theory. (Authors)

Looked for evidence of an intermediate stage between the second and third stages in multiple seriation during which subjects seriate the material on one dimension and classify it on the other. Fine grained analysis of stages is considered useful in elucidating the mechanisms of progression through a stage sequence. (GO)

A set of studies investigated the relative importance of operative schemes and figurative (rote) memory. In Study I, 60 concrete operational children from grades 1-4 were asked to reconstruct two types of stimuli from memory. In order to separate the effects of operative and figurative skill use, learning disabled children with poor figurative…

A significant positive correlation between multiple classification was found, in testing 65 children aged 6 to 8 years, at the stage of concrete operations. This is interpreted as support for the existence of a structure d'ensemble of operational schemes in the period of concrete operations. (Authors)

This study investigates (1) the relationship of two potentially valuable measures of sequential processing to each other and to a measure of digit span, and (2) the relationships among tests of sequential processing and other measures of cognitive functioning. Subjects were 188 first grade students who had been screened in kindergarten for risk of…

Investigates the role of operative schemes in explaining older children's superior memory on past Piagetian memory tasks. Contrasts were made between the performance of normal v learning disabled grade school children, and between preschool children who either possessed or lacked seriation schemes. (Author/SS)

This study attempted to determine whether a combination of seriation and classification training would produce more general intellectual gains. (Author/SB)

A study was designed to develop an instrument and methodological procedure to assess transitive relations within seriation problems in elementary school children using three criteria: explanations, judgments, and strategies. A secondary analysis to assess transitivity used the three criteria according to whether the children were conservers, in…
