In the subject matter of functional relationships, a student's ability to translate from one form of representation to another is seen as a central competence. In the course of the HEUREKO project (heuristic work with representations of functional relationships and the diagnosis of mathematical competencies of students), a theoretical competence…

This paper presents a theoretical account of certain aspects of sentence comprehension, particulary the processes involved in deciding if a sentence is true or false. (Editor)

In this article, 41 models of covariation detection from 2 x 2 contingency tables were evaluated against past data in the literature and against data from new experiments. A new model was also included based on a limiting case of the normative phi-coefficient under an extreme rarity assumption, which has been shown to be an important factor in…

This article is an attempt to advance the effort to reconceptualize communication. (Author)

A case is made that typing, speaking, and playing music are members of a family of skills that can be studied within a common theory. (Editor)

In the present study, cognitive performance was examined by analysing a path model which included family environment variables, social status indicators, and a set of enabling conditions consisting of self-esteem, attitudes toward schoolwork and educational and occupational aspirations. (Editor)

Attempts to propose a cognitive process model of problem finding, operationally define problem finding, and to present empirical evidence for the proposed model. (Author/RK)

This study attempts to discriminate between 2 theories about strategies Ss use when trying to remember a linear ordering. (Editor)

Presents MAC/FAC, a model of similarity-based retrieval that attempts to capture psychological phenomena; discusses its limitations and extensions, its relationship with other retrieval models, and its placement in the context of other work on the nature of similarity. Examines the utility of the model through psychological experiments and…

Discusses current use of psychological theory in software science and reviews recent developments in cognitive psychology relevant to programing (human information processing, expert-novice differences). Critique of Maurice Halstead's model of cognitive aspects of programing and a structured data flow perspective (control flow and data flow…

Results of the experiment provide support for the neo-Piagetian model. (Author)

Performance demonstrated that the conceptual style and cognitive tempo of the model changed the styles and tempos of the Ss and that these effects generalized to independent tasks. (Author)

Describes the construction of a knowledge representation from the identification of the problem (nephrotic syndrome) to a running computer simulation of causal reasoning to provide a vertical slice of the construction of a cognitive model. Interactions between textbook knowledge, observations of human experts, and computational requirements are…

Suggests some reasons why the exploration and description of language function is often an untidy exercise but, none-the-less very rewarding and rich in implication for English teaching. (Author/RK)
