Two experiments examined children's early judgments about numerical relations. Found that children as young as three years old are already adept at reasoning about relations between sets, independently of their ability to form numerical representations. Results support the existence of protoquantitative schemas, or ways of thinking about relations…

First, second, and third graders (n=33) were observed in classrooms during a three-year study of the development of private speech and its relationship to behavioral accompaniment to task, attention, and task performance. Findings agreed with Vygotskian predictions that private speech promotes effective task-related behavior. (SH)

Forty-seven elementary and middle school students, most with learning disabilities, used a computer-assisted instruction program which rapidly presented seven pieces of information or one which cumulatively presented smaller information "chunks." Both groups worked to mastery level successfully, but the cumulative group spent one-third…

Three experiments demonstrated that increasing the length of a mobile serial list impaired 6-month olds' memory for serial order. Findings indicated that the primacy effect was absent on a 24-hour delayed recognition test and was exhibited on a reactivation test, adding to growing evidence that young infants possess two functionally distinct…

Four conditions of a standard false belief task were administered to 10 children with specific language impairment (SLI), 10 children of the same age, and 9 younger children with comparable language skills. Results found that linguistic competence served as a limiting factor in false belief performance in children with SLI. (Contains references.)…

Two experiments used Visual Expectations Procedure to investigate development of expectations in infants up to 12 months old. Reaction time improved and the percentage of anticipations increased between 6 and 9 months using an alternation pattern or a complex pivot pattern, and between 4 and 8 months when using a left-right alternation or a…

Two experiments related structure of a task to underlying cognitive mechanisms. Found that 3-year olds were no better at predicting behavior from partially true beliefs than from entirely false beliefs. Three- and 4-year olds, and autistic children had distinct performance profiles across tasks. Concluded that conceptual foundations for a…

This study investigated acquisition of music performance skills over 11 practice trials in novice and expert pianists differing in age, training, and sight-reading ability. The finding of a strong positive relationship between the mastery of temporal constraints and planning abilities within performance suggested that these two cognitive…

Critical variables that underlie the performance of a national sample of young adults on a diverse set of document literacy tasks were identified. The final sample was 3,618 adults. The identification of these variables provides an important first step toward building a theoretical model that would systematically account for the constructs of…

As early as 1964, cognitive preference was introduced as a way of describing an individual's preference for applying, relating or questioning information. To determine the role of cognitive preference in the pattern of variables predicting teachers' ratings of students' performance, 44 high school students completed a 61-item cognitive preference…

Two studies examined the effects of different types of imaginal elaborations on recall. In Experiment 1, 6-year-olds, 9-year-olds, and college adults were given 20 word pairs embedded in one of four types of sentences: short plausible, bizarre, personalized, or self-generated. With no mention of a memory test, subjects were asked to use the…

A reliable, easily administered performance test of selective attentional ability was sought. A monaural listening task provided a baseline control for adequate hearing and memory; a dichotic listening task then provided indices of ability to focus attention and resist distraction while a simultaneous listening task provided measures of ability to…

Two instructional programs with differing emphases on linking to existing knowledge and experience were used to present elementary dynamics to physics (N=67). Effects on aspects of cognitive structure and performance were investigated. Propositions elicited by a modified word-association technique were used to assess linking in cognitive structure…

Three passages of fifth-grade readability were read and recalled by 24 high- and low-ability fifth graders and college students. These passages were characterized as either narrative (high degree of temporal linkage), expository (logical linkage and abstract content), or mixed (logical linkage but with content suggestive of a narrative). The…
