In 4 experiments, participants made judgments about forces exerted and resistances put up by objects involved in described interactions. Two competing hypotheses were tested: (1) that judgments are derived from the same knowledge base that is thought to be the source of perceptual impressions of forces that occur with visual stimuli, and (2) that…

Several types of parameterizations of attribute correlations in cognitive diagnosis models use the reduced reparameterized unified model. The general approach presumes an unconstrained correlation matrix with K(K - 1)/2 parameters, whereas the higher order approach postulates K parameters, imposing a unidimensional structure on the correlation…

Described is a two-pronged approach to assessment of cognitive-communicative functions in head injury, incorporating elements of both restorative and compensatory models. The approach combines: (1) use of standardized cognitive measures, and (2) observational protocols for systematic evaluation of functioning on integrated, multicomponent tasks…

The cognitive processes in a widely used, non-verbal test of analytic intelligence--the Raven Progressive Matrices Test (J. C. Raven, 1962)--were analyzed. The analysis determined which processes distinguished between higher-scoring and lower-scoring subjects and which processes were common to all subjects and all items on the test. The analysis…

Fifty-five recent studies of individual differences (IDs) in elementary cognitive tasks (ECTs) are reviewed. Twenty-five data sets are examined, analyzed, or reanalyzed by factor analysis. The following promising dimensions are identified: basic perceptual processes, reaction and movement times, mental comparison and recognition tasks, retrieval…

Discusses the design and test of a game simulation research instrument called "Television in the Courtroom" which is used in an attempt to determine the processes by which people deliberate and reach conclusions under conditions of uncertainty. (MH)

A new framework for designing qualitative studies is described to optimize the emergence, representation and presentation of insights. The framework, called Reflection Methodology, is presented as a "Conversational Paradigm" that includes four components--interviewer (researcher as participant); child, task situation, and observing…
