Comparison is one of the most ubiquitous and versatile mechanisms in human information processing. Previous research demonstrates that one consequence of comparative thinking is increased judgmental efficiency: Comparison allows for quicker judgments without a loss in accuracy. We hypothesised that a second potential consequence of comparative…

Stimulus over-selectivity refers to behavior being controlled by one element of the environment at the expense of other equally salient aspects of the environment. This is a common problem for many individuals, including those with autism spectrum disorders, and learning difficulties, and presents a considerable problem for information processing…

The superiority of learner-paced over system-paced instructions was demonstrated in multiple experiments. In these experiments, the system-paced presentations were highly speeded, causing cognitive overload, while the learner-paced instructions allowed adjustments of the presentational flow to the learner's needs by pacing facilities, mostly…

In four experiments, we investigated whether masked stimuli in priming experiments are subjected to early or to late selection. In Experiment 1, participants classified four target-pictures as being small or large. In line with early selection accounts, prime-pictures with a different perceptual appearance as the experienced targets did not elicit…

Conflict adaptation effects refer to the reduction of interference when the incongruent stimulus occurs immediately after an incongruent trial, compared with when it occurs after a congruent trial. The present study analyzes the key conditions that lead to adaptation effects that are specific to the type of conflict involved versus those that are…

A cognitive model of human learning with understanding is introduced. Empirical research supporting the model, which is called the generative model, is summarized. The model is used to suggest a way to integrate some of the research in cognitive development, human learning, human abilities, information processing, and aptitude-treatment…

Voluntary motor actions aim at and are thus governed by predictable action effects. Therefore, representations of an action's effects normally must become activated prior to the action itself. In 5 psychological refractory period experiments the authors investigated whether the activation of such effect representations coincides with the response…

The hypothesis that the "self" concept is active in memory was tested in a series of recognition experiments involving first- and third-person sentences under several instructional conditions. Results were interpreted as congruent with the notion that the "self" can be seen as a cognitive structure with both a memory component…

Research performed, in part, while the author was a research assistant at the Wisconsin Research and Development Center for Cognitive Learning; remainder conducted at the University of Texas under a National Science Foundation - USDP grant. (VM)

Discusses computational studies of learning in artificial neural networks and findings that may provide insights into the learning abilities of the human brain. Describes efforts to test theories about brain information processing, using artificial neural networks. Vignettes include information concerning how a neural network represents…

Research performed while Shannon Moeser was on a Science Scholarship of the National Research Council (NRC) of Canada, and forms part of this author's doctoral thesis submitted to McGill University. Research also supported by an NRC grant to Mr. Bregman. (VM)

While it is clear that schizophrenic patients often exhibit disordered thinking, the specific nature of the deficit and its role, either as a basis of abnormal behavior or as a symptom of malfunction in some underlying control process, remain to be clarified by research and by theory. Describes two experiments on the performance of conceptual…
