This study investigated taxonomic clustering and use of frequency associations as features in the semantic memory of children (n=30 in grades two and six) with learning disabilities (LD). Results suggested that, when individual child-generated word lists (i.e., meaningful) are used, children with LD may not be impaired in their ability to utilize…

Four studies assessed whether children and adults saw categorization decisions as objective matters of fact or as invented conventions. Found that preschoolers treated basic-level animal and human-made artifact category decisions as objective, with kinds of animals treated as more objective than kinds of artifacts. Adults' judgments were similar…

Compared parents and nonparents to examine differences in the use of gender stereotyping to classify children's toys, and differences according to children's ages. Findings for 206 toys suggest that while toys are gender stereotyped for all age groups, there is more flexibility in gender stereotyping of toys for infants and toddlers. (SLD)

Two experiments used the preferential looking task to assess early word comprehension in 12- to 24-month olds. Results indicated that when target stimuli were named, 12-month olds displayed an increase in target looking for typical--but not atypical--targets, whereas 18- and 24-month olds displayed increases for both. (Author/KB)

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…

Examined relationships among theory of mind construct of intention and false belief, problem-solving ability, metacognitive regulation, and strategy use in 39 preschoolers. Found significant correlations between strategy use and theory of mind, and metacognitive regulation and theory of mind. A moderate, but nonsignificant, correlation was found…

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…

Six match-to-sample picture/object selection experiments explored 3- to 5-year-olds' knowledge about superordinate words and acquisition of this knowledge. Findings indicated that number of standards (one versus two), types of standards (different versus same basic-level categories), and nature of representation (pictures versus objects)…

The purpose of this study was to examine the behavioral and demographic characteristics of deaf males enrolled at state school for the Deaf. An analysis of student, family, and educational variables was conducted in order to provide a composite description of both the type and frequency of the offenses and of the offender. Participants were 90…

The efficacy of online learning programs is tied to the suitability of the program in relation to the target audience. Based on the dataset that provides information on student enrollment, academic performance, and demographics extracted from a data warehouse of a large Southwest institution, this study explored the factors that could distinguish…

This study compared perceptions of mentoring relationships among early adolescents, middle adolescents, and emerging adults. In ten focus groups, 56 middle school, high school, and college students described relational experiences that were analyzed thematically. Differences in the characteristics of the mentors nominated by the youth across the…

To understand the co-occurrence of multiple types of violence, the authors developed a behavioral typology based on self-reports of suicidal behaviors, physical violence, and psychological abuse. Using a sample of dating adolescents from a high-risk school district, they identified five clusters of behaviors among the 1,653 students who reported…

To examine the number of subjective age categories in the post-high school portion of the American lifecycle, adult respondents sorted cards describing people in terms of major life events and classified them according to age. A nonlinear decrease in the number of age distinctions occurred in the late portion of middle age (46-65 years). (Author)

Development of the ability to classify auditory patterns was studied at grades 2, 6, 10, and 12 and at adult age levels. Both accuracy and feature use in classification were consistent across age; the age changes that did occur appeared to be due to differences in perception rather than process. (JMB)

Three studies were conducted to investigate reasons for the difficulties that children under 5 years of age experience with class inclusion tasks. The studies tested the claim that such tasks have a structural complexity that is beyond the children's processing ability. In experiment 1, class inclusion tasks were compared with other classification…
