Explored influence of changes in kindergartners' knowledge about a protagonist on earlier constructed memories of the story. Found that children's story recall was affected by their prior impressions. Following the second knowledge manipulation, children revised story reports consistent with newly acquired impressions, suggesting that they had…

This study investigated whether deafness contributes to enhancement of visual spatial cognition, independent of knowledge of sign language. Comparison of 12 congenitally deaf children not exposed to sign language and 12 matched hearing controls found that the groups did not differ in their performance on visual spatial skills tests.

Analyzed rural Guatemalan data on early biological indicators, graduated parameters of social structure, and preschool cognition in relation to primary school grade attainment and adolescent psychoeducational test performance. Performance declined as the number of risk factors to which a subject was exposed increased. Primary education was…

Four studies examined the influence of essentialist information such as internal properties and perceptual similarity on 3-, 4-, and 5-year olds' interpretations of labels. Results suggested that children have essentialist beliefs about animals, but not about artifacts, and that these beliefs interact with children's assumptions about word meaning…

A study involving 12 preschool children with mental retardation, 13 children with autism, and 21 controls failed to show any facilitative effects of the use of representational and nonrepresentational cues on the performance of the children with and without autism on false belief tasks. (Contains references.) (CR)

Used multiple-baseline design to assess the utility of presenting three types of cues when teaching an abstract concept such as colors to three children with autism: plain, label, and symbol. Found colors presented with cues were easier to learn than color without cues. Findings support the need for sensitivity for the highly individualized…

A study of two forms of the Auditory Reading Test with 53 elderly participants with normal or low vision and hearing found mild-to-moderate hearing loss did not reduce auditory reading rates as much as expected. Participants with low vision read as quickly using computers and natural speech as sighted participants. (Contains references.)…

Three experiments examined the relative importance of original function and current function in artifact categorization for young children and adults. It was concluded that 6-year-olds have begun to organize their understanding of artifacts around the notion of original function, whereas 4-year-olds have not. Data were examined in terms of how…

Describes connectionist model showing exclusivity asymmetries when categorizing visual stimuli, similar to pattern shown by infants. Examines asymmetries in terms of an associative learning mechanism, distributed internal representations, and statistics of feature distributions in the stimuli. Details test of model with infants, finding that…

Critiqued six methods that have been used to study the relationship between per pupil expenditures and student achievement and considered two methods used to summarize the results that have produced conflicting conclusions. Results of the critique suggest that a preponderance of the evidence supports the existence of a positive relationship…

Five knowledge management (KM) experts discuss answers to six fundamental issues of KM that address: a definition of knowledge and KM; relationship between business and KM; whether technology has helped the knowledge worker; relationship between learning, performance, knowledge, and community; the promise of knowledge ecology or ecosystem and…

Examined whether the presence of implicit links between social groups and high versus low status attributes affected formation of intergroup attitudes among 7- to 12-year-olds. Found that children's intergroup attitudes were affected by a status manipulation when teachers made functional use of the novel groups. Children who were members of…

Examined school improvement plans under conditions of high-stakes accountability. Found that schools responded to performance demands of the accountability system with a pattern of external obligation (e.g., state and local requirements rather than teachers') and internal managerialism. School improvement plans were less useful as tools for a…

Two experiments documented that conceptual knowledge influences 3-year-olds' extension of novel words. When objects were described as having conceptual properties typical of artifacts, children extended novel labels on the basis of shape. When same objects were described as having conceptual properties typical of animate kinds, children extended…

Three studies involved kindergartners in a categorization task with an adult in collaborative and noncollaborative conditions; tested subjects on memory of who had performed which actions; and asked them to recategorize items independently. Results suggested that one process contributing to children's internalization of knowledge may involve…
