Category learning can be characterized as a process of discovering the dimensions that represent stimuli efficiently and effectively. Categories that are overlapping when represented in 1 dimensionality may be separate in a higher dimensional cue set. The authors report 2 experiments in which participants were shown an additional cue after…

We examined need for cognition, social desirability, and communication apprehension for their influence on the mention and repetition of shared and unshared information in 8-person decision-making groups. Both need for cognition and social desirability influenced the discussion of shared and unshared information in decision-making groups. The…

The author comments on the article "The Primacy of Cognition in Schizophrenia," by R. W. Heinrichs and states that to the pursuit of schizophrenic/normal differences, there is no end. Heinrichs used meta-analyses to argue persuasively for the primacy of cognition for this role. His conclusion not only elicited agreement from both researchers and…

The Zahlen-Verbindungs-Test (ZVT) represents a highly feasible measure of information-processing speed that correlates quite highly with standard psychometric tests of intelligence. The present study was designed to identify specific stages of the sensorimotor processing system that may account for individual differences in overall variability of…

To examine metacomprehension during comprehension, undergraduates (n = 133) were asked to provide descriptions of how they determined the meaning of four rare words presented in short passages. Content analysis of these written descriptions revealed task-specific metacomprehension reflecting lexical, textbase, and situation model processes.…

Two studies were done to investigate the effects of personality, as dichotomized along a thought-action dimension, on time perception. Results of both were similar. The high-extraversive subjects underestimated and the high-introversive subjects overestimated time. (Author)

This quantitative study of imagery in 96 undergraduates addresses the problem of individual differences in the characteristics of mental imagery workspaces. A 20-item questionnaire embodying nine characteristics of mental imagery workspaces was administered to 78 females and 18 males. Analysis of variance by gender disclosed significant higher…

Research has suggested that memory performance may be related to the extent of stimulus processing during acquisition. To examine processing efficiency and processing deficiency differences between younger and older adults, four studies were conducted. In the first study, young and old adults rated word lists, manipulated for generation specific…

In experiments on individual differences in learning, knowledge prerequisites and learning strategies have been shown to be important factors. The author questions whether learning optimization should rely on direct measures from outside the learner or should elucidate and strengthen the individual's capacity for learning decisions. He proposes to…

The present paper presents a discussion of certain dimensions of cognitive style that are subsumed under the theoretical formulation of cognitive control theory. An overview of cognitive-control theory is presented first. Second, the cognitive control principle of tolerance for unrealistic experience is then defined and the relevant literature is…

The Trait Treatment Interaction (TTI) Process approach is particularly adapted to the study of information-processing by receivers of information presented in the media. Differences in people's experiences do lead to different cognitive structures. Different people use the same machinery of perceiving, coding, storing, and retrieving. Neverthless,…

Psychological experiments investigating imposed and induced cognitive strategies are reviewed and related to operations in reading comprehension. It has been suggested that comprehension differences between good and poor readers may arise from the way in which they habitually organize intra- and inter-sentence elements during input.…

The predictability of individual differences in the ability to reason about dynamic displays from tests using static displays was studied in 170 adults given paper-and-pencil and computer controlled tests. Several multivariate analyses indicated that the ability to reason about dynamic motion was distinct from the ability to reason about static…
