Assesses five- and 10-year-old children's understanding of second-order belief structures in acted stories in which two characters were independently informed about an object's unexpected transfer to a new location. Results show unexpected early competence around age six or seven under optimal conditions when inference of second-order beliefs is…

Second and third graders and fifth and sixth graders were tested in a very large, unfamiliar environment to determine the relation of their knowledge of an abstract reference frame to performance on a spatial inference task. (HOD)

Investigates the relationship between class inclusion and reasoning in 56 Dutch Children between 6 and 14 years of age. Concludes that when the children failed to respond correctly to questions about the validity of syllogisms, they did so because they lacked sufficient understanding of the premises. (HOD)

Describes three experiments that tested autistic children's nonverbal and verbal categorization abilities. Concludes that autistic children do not suffer a specific cognitive deficit in ability to categorize and form abstract concepts. (HOD)

This study examined the relationship between adaptive functioning and intellectual functioning in 18 children with autism and mental retardation and 20 children with mental retardation. The children with autism showed significantly more impairment in adaptive behavior composite scores, verbal reasoning abilities, socialization skills, and…

The Cognitive Levels Test, for use with ages 5-21, is designed as a quick cognitive assessment instrument with 4 subdomains: verbal reasoning, abstract reasoning, quantitative reasoning, and memory. This paper describes the test's administration, summation of data, standardization, reliability, and validity. (JDD)

A sample of 217 students (from grades 4 to 8) who were enrolled in an elementary school science-oriented gifted and talented program were compared to 91 mainstreamed subjects in grades 7 through 10. Assessement instruments included: a battery of Piagetian measures designed to assess combinatorial reasoning, probabilistic reasoning, and the ability…

Compared and contrasted are the concepts intuition and logic. The ideas of conceptual thought and algorithmic thought are discussed in terms of the world as a labyrinth, intuition and time, and the structure of knowledge. (KR)

This study investigated: (1) whether boys and girls master formal reasoning tasks to the same degree at the same age; (2) if the variance of boys' and girls' performance in formal tasks could be predicted by the same cognitive learning abilities; and (3) what are the main and interactional effects of age, sex, and school type on the variance of…

Cognitive science research offers hope for the development of innovative science teaching strategies that facilitate the development of optimally interconnected procedural and declarative knowledge networks. Improving students' neural networks should improve their abilities to think critically, reason logically, learn more efficiently, and solve…

Evidence from the research literature suggests that a variety of cognitive factors are responsible for chemistry achievement. This investigation examined the role that four cognitive factors, namely, prior knowledge, formal reasoning ability, memory capacity and field independence/dependence, play on achievement in chemistry as measured by tests…

The purpose of this study was to examine for the middle grades how students' cognitive reasoning level contributes to the variability of their achievement test performance. While previous investigations have indicated that measures of reasoning development are associated with measures of achievement, few such studies have attempted to control for…
