A uniprocessor, unidimensional model, based on Krueger's noisy-operator theory, was fitted satisfactorily to data from four published studies of tone comparison. The model predicts faster response time on different judgments because of heterogeneity of difference. (Author/CP)

Recent research in the area of individual differences in learning and memory is reviewed from a cognitive perspective. Using the two-state model of memory as a framework, individual variations in attentional, short-term store, and long-term store processes are discussed. (Editor)

Describes a new integrated bio-psycho-social model of etiology for mental retardation. Discusses the problems with current models and the ability of the "universe line" model to integrate data from different research areas, especially cognitive and psychopathologic indicators. Addresses implications of this theoretical approach. (Author/CR)

Studies cognitive pragmatics in order to bridge the gap between the universality and culture-specificity of politeness by means of the idea of the "frame" or "specific knowledge" combined with the theory of relevance by Sperber and Wilson. The article concludes that a general theory of politeness as a particular subsystem in a…

Presents data from a positron emission tomographic study in which subjects were asked to produce the past tense forms of regular, irregular and nonce stems. Findings, which support the grammar/lexicon linguistic theories, reveal different amounts and areas of cortical activation in the regular and irregular tasks, as well as significantly…

Reviews the major literature on creative processes in children that should be predictive of adult creativity, focusing on affective processes and children's play. Describes Russ's (1993) model of affect and creativity, and cognitive processes, personality processes, and affective processes important in creativity. Discusses theories of play,…

Presents a tentative cognitive-psychological model of language attrition, which draws on information from studies in second language attrition, neurobiology and psychology. Notes that this model is presented to demonstrate that a model based on consideration of the brain has the potential of providing a plausible account of the process of language…

Examines ways in which intelligent tutoring systems can be used to develop models of a student's domain knowledge, problem solving abilities, and learning strategies. Cognitive skills assessment is discussed, and an example of a problem based tutoring system, Qualitative Understanding of Electrical System Troubleshooting (QUEST), is explained. (25…

Argues that individual and group differences in priming performance scores are heavily influenced by overall speed and accuracy, and thus are a flawed reflection of internal activation of semantic priming. Suggests that meaningful comparison of groups on the activation underlying priming difference scores requires removing the effects of overall…

A model is proposed for the general abstracting process (using disciplines such as linguistics, logic, and psychology) that is based on a system of combined strategies with four stages: reading-understanding; selection; interpretation; synthesis. (Author/JKP)

Diagnostic assessment combining cognitive science and psychometrics, cognitively diagnostic assessment (CDA), is characterized in terms of the intended use of the assessment and methods of developing and evaluating assessments. Societal trends motivating the development of CDA and efforts to develop a five-step methodology for CDA are outlined.…

In 2 experiments, 261 middle school students processed an analogy and responded to factual and inferential target-domain questions in a study of variables that contribute to the formation of analogical misconceptions. Results of both experiments support a six-variable model of analogical misconception formation. (SLD)

Describes a study that examined interactions between users and intermediaries prior to online searching to examine communication about the user's stage in the search process. A model of information seeking that views the information search process as a series of cognitive stages is presented, and implications for user-intermediary interactions are…

An error in the data analysis for a study reported in a 1988 paper by Kail is cited. The paper postulated a model that explained individual differences in the speed of processing on cognitive tasks. Reanalysis of the data suggested that support for the original conclusions is considerably weaker than reported. (LB)

Didactic transposition theory asserts that bodies of knowledge are designed not to be taught but to be used. Discusses didactic transposition, the transposition of knowledge regarded as a tool to be used to knowledge as something to be learned in mathematics textbooks. (14 references) (MDH)
