Five experiments examined matching to sample procedures among preschoolers. Results indicated that children selected taxonomic comparisons more often than thematic comparisons, independent of age, gender, instructions, order of trial type, specificity of feedback, presence of unrelated third comparisons, and level of taxonomy. Instructions to…

Effects of massage on preschoolers' cognitive performance were assessed. Preschoolers were given Wechsler Preschool and Primary Scale of Intelligence-Revised subtests before and after receiving 15-minute massage or spending 15 minutes reading stories with the experimenter. Children's performance on Block Design improved following massage, and…

This article discusses factors that contribute to the difficulties that many postsecondary students with learning disabilities have in meeting the mathematics demands, including: characteristics of learning disabilities in math, inadequate preparation for postsecondary math demands, difficulties with assessment and identification, and…

Examined three possible explanations for findings that infants detect textural discrepancies based on individual features more readily than on feature conjunctions. Found that none of the proposed factors could explain 5.5-month-olds' superior processing of featural over conjunction-based textural discrepancies. Findings suggest that in infancy,…

Four experiments examined very young infants' expectations about containment events. Found that 2- to 3.5-month-olds recognized that objects could be lowered inside a container with an open but not a closed top. Three-and-a-half-month-olds realized that objects could not pass through the container's back wall and should have moved with it to a new…

Examined implicit learning in 432 four- to 10-year-olds in 3 experiments, using a new paradigm based on drawing behavior. Found that children modified drawing behavior following specially devised practice in such a way that the changes could not be viewed as resulting from deliberate adaptive strategies, with modifications lasting for at least 1…

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. (Author/DB)

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…
