Cognition could be seen as a cascade of top-down and bottom-up processes across behavioural and psychophysiological layers in a cognitive architecture. Typical behavioural measurements used in education do not give information about lower cognitive layers. Event-Related Potentials (ERPs) derived from electroencephalography allow researchers to…

Categorical data become increasingly ubiquitous in the modern big data era. In this dissertation, we propose novel statistical learning and inference methods for large-scale categorical data, focusing on latent variable models and their applications to psychometrics. In psychometric assessments, the subjects' underlying aptitude often cannot be…

The interpretation of cognitive test scores often leads to decisions concerning the diagnosis, educational placement, and types of interventions used for children. Therefore, it is important that practitioners administer and score cognitive tests without error. This study assesses the frequency and types of examiner errors that occur during the…

Receiver operating characteristic (ROC) analysis is being used increasingly to examine the memory processes underlying recognition memory. The authors discuss the methodological issues involved in conducting and analyzing ROC results, describe the various models that have been developed to account for these results, review the behavioral empirical…

This paper is a report of the replication of a seminal study on cognitive presence in computer mediated conferencing (CMC) by Garrison, Anderson, and Archer (2001). A comparison of cognitive presence coding by three different researchers is also demonstrated. The study re-ignites debates about what constitutes the segment of CMC data to be coded…

The possibility is considered that research on intelligence is entering or is about to enter a time of crisis. First, it is suggested that the decline of the psychometric paradigm as the primary means for studying intelligence was due in part to the failure of users of the paradigm to meet in a highly successful way four challenges that confronted…

The decline of the psychometric paradigm for studying intelligence was due in part to its failure to meet four challenges. On the surface, users of the information-processing paradigms seem successfully to have met these challenges, but at a deeper level, the level of success is not so great. (Author/BW)

Discusses problems involved in testing Piaget's hypothesis of topological primacy in representational space by copying geometric figures. (Author/SS)

A reply to a rejoinder in which Pascual-Leone defended his quantitative model of children's information processing capacity. Trabasso focuses on empirical evidence in presenting his reply to this rejoinder. (BD)

Presents an analysis of Pascual-Leone's quantitative model for the measurement of the cognitive capacity of children. Presents an experiment in which 8-year-old children are asked to reproduce single actions and combinations of actions modeled by an experimenter. (BD)

Significant correlations between measures of cognitive structure and performance were found using a procedure distinguishing between episodic and semantic memory as an heuristic with achievement test items. The design increased the likelihood of indications of semantic memory. Higher-order and lower-order cognitive processes are discussed.…

A reply to a critique of Pascual-Leone's model of children's information processing capacity. (BD)

This study objects to the "very specious statistical arguments" of Ernest Sternglass and Steven Bell in the April issue of this magazine, in which illogical and inconsistent statistical evidence suggested cognitive damage during infancy may be linked to atmospheric testing of nuclear weapons from 1954 to 1963.

Investigates the psychometric adequacy of Steers and Braunstein's (1976) Manifest Needs Questionnaire. Research results indicate that the instrument possesses adequate stability but lacks adequate internal consistency. Factor analytic procedures fail to replicate the a priori factor structure. Results are compared with Steers and Braunstein's…
