Two experiments were conducted to study the development of mental rotation abilities in late childhood, adolescence, and adulthood. Subjects were third, fourth, and sixth graders, and college students. (MP)

Investigated was the hypothesis that high arousal increases processing of physical characteristics and reduces processing of semantic characteristics. While introverts and extroverts had equivalent scanning rates for physical features, introverts were significantly slower in searching for semantic features of category membership, indicating…

This review of the concept learning literature indicates that the greater effectiveness of field-independent learners is related to memory efficiency and the ability to conduct combinatorial analysis. Short-term memory and free recall studies suggest factors contributing to the less efficient memory of field-dependent learners. (Editor/SJL)

Studaxology is a theory that explains to the college student how to become organized within the study environment, based on what the student experiences while studying. Its core is a 3x3 matrix of study experiences. Interpretation of the matrix enables the student to meet deep-level learning demands for optimal functioning in higher education.…

This article considers whether Asperger syndrome (AS) should necessarily be viewed as a disability or as a difference. It concludes that "difference" is a more neutral and fair description. A model (the emphasizing-systemizing model) is summarized that attempts to define in what way individuals with AS are different. (Contains references.)…

Examined developmental and individual differences in tendencies to favor analytic over heuristic responses in three tasks (inductive reasoning, deduction under belief bias conditions, probabilistic reasoning) in children varying in age and cognitive ability. Found significant increases in analytic responding with development on first two tasks.…

Examined potential central processing strategy differences among subgroups of children on a series of elaborative encoding tasks. Children in lower verbal and learning ability subgroups differed from those in higher ability groups in how they shared, discriminated, and selectively allocated resources between recall tasks. (RH)

Examined the role of individual differences in working memory and lexical access in age- and reading skill-related differences in performance on phonological synthesis tasks. The performance of 28 kindergarten, first-, and second-grade students with normal reading skills, and that of 28 reading-disabled second graders, was compared under four…

In the face of increasing cultural diversity, educators need new ways of understanding how children think. The theory of multiple intelligences provides a means for distinguishing the many ways children have to solve problems and create products, identify cognitive strengths, and group students according to complementary intelligences.

The time may be ripe for the fields of mathematics education, special education, and cognitive psychology to converge, with their respective focuses on mathematical problem solving, individual differences among students, and analysis of cognitive processes. Four articles on learning disabilities in mathematics are introduced, and a research agenda…

In 2 experiments involving 271 elementary and middle-school students with greater and lesser writing skills, components of the writing-translating process were examined. Skilled writers showed more fluent sentence-generation processes and were faster on lexical decision-making tasks. Fluent translating may help reduce the working-memory load…

University students were screened to determine whether some could comprehend text well despite very poor recoding skills, measured by pseudoword reading. There was no evidence that resilient readers relied on superior verbal ability or working memory to compensate for poor recoding. Resilient readers were poor at spelling, reading isolated words,…

Analyzes second-language learners' processing of linguistic data within the target language, focusing on input and intake in second-language acquisition and factors and cognitive processes that affect input processing. Input factors include input simplification, input enhancement, and interactional modifications. Individual learner differences…

This study identified cognitive processes that underlie individual differences in working memory (WM) and mathematical problem-solution accuracy in elementary school children at risk and not at risk for serious math difficulties (SMD). A battery of tests was administered that assessed problem solving, achievement, and cognitive processing in…

We consider human performance on an optimal stopping problem where people are presented with a list of numbers independently chosen from a uniform distribution. People are told how many numbers are in the list, and how they were chosen. People are then shown the numbers one at a time, and are instructed to choose the maximum, subject to the…
