Cognitive diagnosis models are diagnostic models used to classify respondents into homogenous groups based on multiple categorical latent variables representing the measured cognitive attributes. This study aims to present longitudinal models for cognitive diagnosis modeling, which can be applied to repeated measurements in order to monitor…

An artifact encountered in regression models of human judgment is explored. The direction and magnitude of the artifactual effect is shown to depend upon the nature of the experimental task and task conditions. Use of an alternative index is recommended. (Author/JKS)

An attempt to lend empirical support to the structure-of-intellect (SI) model by investigating 10 difficult to separate parallel factors. (Author/CK)

Although deficits in visual attention are often postulated as an important component of many declines in cognitive processing and functional outcomes in older adults, surprisingly little emphasis has been placed on evaluating psychometric instruments with which individual differences in visual attention ability can be assessed. This article…

Developed a multidimensional measure of affect and cognition in relation to adult learning of computing skills, the Computer Anxiety and Learning Measure (CALM). Results from 794 Australian undergraduates support the validity and reliability of the CALM with this population, although whether the measure is invariant across different adult…
