Provides new evidence for mathematical problem-solving abilities of preschool children. These problem-solving behaviors occurred in a study of sharing of discrete items by dealing, in which we examined the abilities of three categories of counters to solve a discrete redistribution problem. Identifies problem-solving strategies used in the context…

Investigates the effect that manipulation of the extent of formal reasoning required for solving chemistry problems has upon student performance, and presents a cognitive model for the qualitative analysis of that effect. Concludes that the developmental level of students is the most important predictor of problem-solving success given significant…

In their reply to the present author's critique (1991), J. H. Kranzler and A. R. Jensen have still not demonstrated that a factor of general intelligence, "g," depends on, or contains, several independent factors. They have only demonstrated that an estimate of "g" is predictable from several independent components. (SLD)

This paper describes a method of understanding student problem-solving behavior during computer-assisted instruction using trigonometry as the example domain. Instead of attempting to model the student's process for solving problems, techniques which infer the equivalence between two adjacent steps in the student's process are used to determine…

Ipsative subtest pattern stability was examined for 60 preschool children (31 males and 29 females) on the Bracken Basic Concept Scale and the Kaufman Assessment Battery for Children over a 4-6 week test-retest interval. The moderate level of profile stability found warrants cautious use of the ipsative interpretation approach. (SLD)

Describes recent developments in intelligence theory, applied measurements, and research methodology that suggests new research is needed to reexamine the relative importance of both general and specific cognitive abilities in explaining school achievement. Presents summary of results that examines relationship between "g" and seven…

Examined validity of use of human figure drawing to evaluate cognitive development status using Piagetian tasks with 7- to 11-year-olds. Found that scores for children's drawings of a man and a woman correlated significantly with mental imaging, conservation of mass, and conservation of length, suggesting the possibility of finding patterns to…

A study involving 18 individuals with pervasive developmental disorders (PDD) (ages 9-21) and 67 controls found total score on the Biber Cognitive Estimation Test for both individuals with PDD and controls progressed consistently with mental age, development being the most dramatic around the mental age of 8 years. (Contains references.)…

Although the veridicality of unconscious perception is increasingly accepted, core issues remain unresolved [Jack, A., & Shallice, T. (2001). Introspective physicalism as an approach to the science of consciousness. "Cognition, 79," 161-196], and sharp disagreement persists regarding fundamental methodological and theoretical issues. The most…

An emerging body of literature points to the prominent role of the frontal lobes in the retrieval of verbs, whereas production of common and proper nouns arguably is mediated primarily by posterior and anterior temporal regions, respectively. Although the majority of studies examining the neuroanatomic distinctions between verb and noun retrieval…

Efforts to test hypotheses derived from social cognitive theory require sound measures of the theory's constructs. Because the theory is concerned with domain-specific aspects of human functioning, it raises special measurement challenges. For example, unlike traits, which can be indexed with general, all-purpose measures, social cognitive…

This project examined some of the common constraints on reliable cognitive assessment for children over time. Repeated measures design (n = 133) was with younger (5 & 6 year old, n = 64) and older (7 & 8 year old, n = 69) children. Results showed that children's self-concepts moderated the test-retest reliability over extended intervals…

How long does it take to form a durable representation in visual working memory? Several theorists have proposed that this consolidation process is very slow. Here, we measured the time course of consolidation. Observers performed a change-detection task for colored squares, and shortly after the presentation of the first array, pattern masks were…

In this study, the effect of different definitions of concavity on students' understanding was investigated. Students enrolled in the calculus-II course in the science and engineering faculties in Anadolu University, Turkey were divided into two groups and each group was given a different definition of concavity. At the end of the study, both…

A study determined the learning (achievement) of 151 participants in the 1992-93 Ohio pesticide applicator training (PAT) program. It assessed the intended level of cognition of instruction and the actual cognition level achieved by the participants. All participants were pre- and posttested using questions adapted from Hall and Prochaska (1991),…
