To understand expertise and expertise development, interactions between knowledge, cognitive processing and task characteristics must be examined in people at different levels of training, experience, and performance. Interviewing is widely used in the initial exploration of domain expertise. Work and cognitive task analysis chart the knowledge,…

The mathematical representation of E. Brunswik's (1952) lens model has been used extensively to study human judgment and provides a unique opportunity to conduct a meta-analysis of studies that covers roughly 5 decades. Specifically, the authors analyzed statistics of the "lens model equation" (L. R. Tucker, 1964) associated with 249 different…

Recent methodological advances have allowed researchers to address confounds in the measurement of task-switch costs in task-switching performance by dissociating cue switching from task switching. For example, in the transition-cuing procedure, which involves presenting cues for task transitions rather than for tasks, cue transitions (cue…

This paper reports on a study on the relationship between cognitive task complexity and linguistic performance in L2 writing. In the study, two models proposed to explain the influence of cognitive task complexity on linguistic performance in L2 are tested and compared: Skehan and Foster's Limited Attentional Capacity Model (Skehan, 1998; Skehan…

Hammond's Cognitive Continuum theory posits that certain task features induce distinct processing modes (e.g., intuitive or analytic) and thus result in qualitatively different decision performance. Although the theory suggests the relation between task features and performance characteristics a priori, the validity of these predictions requires…

Because previous studies had suggestd that Down Syndrome subjects did not respond to changes in directional probability within a complex motor task as did other retarded subjects, 14 Down Syndrome 18-year-olds were given training relative to the directional probability component of the task. Performance was improved but primarily in terms of…

Forty toddlers, 1 1/2 to 3 1/2 years of age, and 8 adults, searched for stickers that were hidden underneath two discretely different classes of objects embedded in arrays containing several classes. Study results suggest that the children appear to have been attempting to determine which kinds of choices were the wrong ones. (Author/RWB)

Reports the use of a memory load-interference paradigm and the easy-to-hard paradigm as converging operations to study capacity limitations in five- to six-year-old's reasoning. Concludes that transitive inference ability in children is capacity limited. (HOD)

This essay, the concluding section of a larger study, examines the present state of cognitive science and instructional theory as reflected in the study's earlier chapters. Cognitive analyses of tasks are reported in the broad domain of language comprehension and production (e.g., understanding, composing, and answering questions about texts). The…

Describes four experiments conducted among adults and 3- to 7-year-olds to validate a task analysis that indicates that the equality, group enhancement, and superiority social decisions require a greater information processing load than the altruism, rivalry, and individualism social decisions. (HOD)

The effects of age, task, and egocentric responding on visual-spatial perspective taking were studied among 41 preschool children between 3.0 and 5.9 years of age. Children were individually administered three perspective-taking measures: the upside-down/right-side-up task, a block task, and a picture box task, all previously described in the…

Explores content or contextual validity of social rule classifications produced by sample of 12-year-old child coders. Analyses of variances revealed that categorization schemes generated by child coders were contextually valid as determined by raters' mean ratings. (Author/RWB)

To lay a foundation for the design and effective use of low-cost, part-task and low-fidelity training devices, this report identifies dimensions of skill performance in terms of modern learning and behavior theory, and analyzes cognitive and motor skills as they relate to information processing. Cognitive processes discussed include task…

Presents a decision model for planning learner feedback in distance education courses with emphasis on college-level teaching. Knowledge components in information processing models of learning are described, task analysis for learning from text is discussed in terms of comprehension, and criteria for designing learner feedback are examined.

Advances in cognitive science have greatly increased our knowledge of how the human mind stores and uses information. That knowledge can be used to decompose curricular objectives so as to increase the specificity of instruction to a level of precision that should greatly enhance student writing. This article identifies some major types of…
