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)

"A new sort of concept attainment or decoding-encoding experimental paradigm based on the model is developed and an experiment on 5-, 7-, and 9-year-olds is reported. (Author)

Describes a conceptual schema based on four basic requirements of the learner--stimulation, order, strategy, and meaning. These basic learner requirements are subdivided to describe the instructional environment necessary to provide an optimum fit between the learner and the environment. Fourteen references are cited.

The phenomenon of cognitive dissonance was examined in relation to consumer habits. (MM)

Describes the difference between mediation and "mediatisation." Suggests the need for a paradigm shift away from the computational model of knowledge as pure information processing and task-centered problem solving to a more contextualist, sociointeractional, constructivist, user-centered model of cognition. (Author/AEF)

This article compares two theories on why children with language impairment have slower response times when completing linguistic and nonlinguistic tasks. First, the slowing is due to difficulty with a particular cognitive processes and second, the slowing is due to a general cognitive processing limitation. Clinical implications are discussed.…

Explores similarities between research approaches characterizing different paradigms in information science and different information-processing styles of individual researchers. Proposes a model of the way in which new knowledge is generated, based on these similarities. The model focuses on "research pathologies," and ways in which the…

How do people judge which of 2 risks claims more lives per year? The authors specified 4 candidate mechanisms and tested them against people's judgments in 3 risk environments. Two mechanisms, availability by recall and regressed frequency, conformed best to people's choices. The same mechanisms also accounted well for the mapping accuracy of…

Computer modelling research has undermined the view that double dissociations in behaviour are sufficient to infer separability in the cognitive mechanisms underlying those behaviours. However, all these models employ "multi-modal" representational schemes, where functional specialisation of processing emerges from the training process.…

Satisfaction is a construct that is important to the development of intrinsic motivation and the continuing effort to learn. Research that helps to identify those factors that contribute to satisfaction is useful in the design of electronic support systems for individuals and groups. This paper investigates the impact of "need for…

One of the most basic theoretical areas in the study of visual communication and visual literacy is the nature of representation. Some of the important research in this area is reviewed in this paper, and a model of representation is developed that satisfies many of the philosophical concerns. The paper begins with a discussion on the relationship…

Noting that understanding how science students respond to anomalous data is essential to understanding knowledge acquisition in science classrooms, this paper presents a detailed analysis of the ways in which scientists and science students respond to anomalous data. The paper postulates seven distinct forms of response to anomalous data: ignoring…
