Research indicates that people do not spontaneously transfer prior clues to solve problems, even though the necessary information is available in memory. To investigate the effects of the symmetry between clue statements and problem statements on problem solving performance, subjects were asked to provide plausible explanations for five…

Etiology-specific profiles of intellectual abilities were compared in 30 males (ages 6-12) with fragile X syndrome, Down's syndrome, or nonspecific mental retardation using the Kaufman Assessment Battery for Children. All three groups scored lower on sequential processing than on simultaneous processing or achievement, and etiology-specific…

Applies to the inclined-plane task Siegler's (1981) observation that performance on Piagetian tasks is governed by similar rule structures. Also replicates Siegler's original observations about the development on the balance-scale task and determines the consistency in children's rule usage across tasks. (Author/AS)

This study with 56 students (mean age 15 years) with mental retardation and 53 nonretarded students (matched for mental age) found that students with mental retardation were more likely to rely on all kinds of external cues (task-relevant, incidental, or misleading) in problem solving, especially when the preceding task had been difficult.…

One hundred students (ages 6-8) described similarities and differences among exemplars of different categories, identified the categories, and named the exemplars. Large performance differences were found between normally achieving and mildly retarded groups and between mildly retarded and learning-disabled groups, with small performance…

Reanalysis of the data from a 1984 study on making and breaking problem-solving mental sets with 50 children found that gifted subjects who failed to initially form the set made the most errors of any group and were least likely to recognize their own errors. Results suggest that motivational reasons may underly this inferior performance by some…

This report incorporates a literature review, a workshop paper, and discussion by workshop participants on the current status of research on what the users of computer systems know, and how these different forms of knowledge fit together in learning and performance. It is noted that such research is important to the problem of designing systems…

This study of 94 college undergraduates, including 24 with a reading disability, found that speech perception was strongly related to 3 of 4 phonological variables, including short-term and long-term auditory memory and phoneme segmentation, which were in turn strongly related to reading. Nonverbal temporal processing was not related to any…

Investigates the extent to which sex stereotypes impose competence (e.g., not knowing about objects) versus performance limitations (e.g., not performing for lack of reward) and the effects of sex stereotypes on exploration among 56 4- to 9-year-old children. (HOD)

This study compared factors contributing to Quick Incidental Learning of new vocabulary by 50 5-year olds with specific language impairment (SLI) and 2 comparison groups. Although SLI children exhibited a robust representational mapping ability, performance was modulated by a minimum input constraint and apparent problems with storage into…

Investigates whether an experimentally imposed 80dB (A) noise affected psychomotor, serial memory words and pictures, incidental memory, visual recall, paired associates, perceptual learning, and coding performance of five-year-old Black children attending day care centers near and far from elevated subways. (HOD)

A study was conducted to investigate the respective contributions of personal and social factors (initial competence and imitation of modeled responses) in children's observational learning of conservation. Subjects included 180 first-grade nonconservers from six schools attended by French-speaking middle class pupils. All subjects failed…

This study was conducted to determine how the pattern of learning on an abstract concept, plate tectonics, differed between groups of different cognitive levels, sex, and intelligence quotient (IQ). The intensive time-series design was used to examine the achievement of eighth grade and ninth grade earth science students. The unique characteristic…

Evaluation of the Kaufman Assessment Battery for Children (K-ABC) with 130 primary school children in Zaire revealed three findings: (1) the distinction between sequential processing and simultaneous processing was valid; (2) the K-ABC discriminated effectively among grade levels, health and family environment variables, and tribal membership; and…

This article discusses the role of perceived self-efficacy during classroom learning of cognitive skills. Self-efficacy refers to personal judgments of performance capabilities in a given domain of activity. Students enter classroom activities with various aptitudes and prior experiences, which affect their initial sense of self-efficacy for…
