Three models have been proposed to account for the relationship between the principle of commutativity and the development of more economical addition strategies, which disregard addend order. In the first and second models, it has been proposed that either discovery or assumption of commutativity is a necessary condition for the invention of…

This paper proposes the use of a rule-based computer programming language as a standard for the expression of rules, arguing that the adoption of a standard would enable researchers to communicate about rules in a consistent and significant way. Focusing on the formal equivalence of artificial intelligence (AI) programming to different types of…

Two instructional design alternatives are described and discussed: (1) the supplantation model of Ausburn and Ausburn (1978), where learning strategies are built into the instructional materials; and (2) a generative design model, where strategies are "built" into the learner. These contrasting models are proposed as representing the…

This discussion of the contributions that cognitive psychology can make to the next generation of instructional design methods begins by comparing behaviorally-based and cognitively-based instructional design systems. Some possible improvements in instructional design are then presented, and it is argued that cognition, or student thought…

The notion of buggy procedures has played an important role in recent cognitive models of mathematical skills. Some earlier work on student modeling used artificial intelligence methods to automatically construct buggy models of student behavior. An alternate approach, proposed here, draws on insights from the rapidly developing field of machine…

The world presented to our senses is essentially continuous in space and time. The simplest observations of children have shown that we are not born with ways of "breaking up" the world. The structures of our knowledge must be developed, and the major issue this paper considers is how those structures develop. The discussion focuses on Jean…

Proposing a shift in the locus of theoretical analysis of cognition, this paper argues that cognitive functioning may be more readily characterized without the mediation of long-term mental associations and structure. An account of cognition is proposed in which mental relations are transient functional relations, and in which psychological…

Dale Hample's cognitive model of argument is designed to reflect the operation of syllogistic thought processes. It has been suggested however, that the model applies more closely to abstractly worded arguments than to concrete thinking and that it also may work better with more interested respondents because it seems to describe the central…

One theoretical model for understanding the visual event suggests that a visual event has both a surface (descriptive) and a deeper (experience) level of understanding. Both levels are needed to comprehend and appreciate images, with each level affecting the other. A person's perspective is an important part of the visual event, which depends upon…

The nature of the developmental shift from adolescence to adulthood has been of ongoing interest to researchers studying the development of socio-moral cognition from within the "cognitive-developmental" paradigm. This paper identifies three dimensions along which developmental changes in socio-moral cognition occur during late…

In a recent note, Catlin and Jones (1976) argued that the sentence picture comparison model of Carpenter and Just (1975) could not account for the results obtained in studies where the picture preceded the sentence. In the present note, it is argued that the model can handle the results without adding additional parameters and that the Carpenter…

Reading is a process that bridges the distinction between perceptual and cognitive processes but the formalisms of the information processing approach to the study of reading apply most naturally either to models assuming a series of noninteracting stages of information processing or to a set of independent parallel processing units. This paper…

Relates J.P. Guilford's model of problem solving to the negotiation of a reference question. (PF)
