E. Dhooge and R. J. Hartsuiker (2010) reported experiments showing that picture naming takes longer with low- than high-frequency distractor words, replicating M. Miozzo and A. Caramazza (2003). In addition, they showed that this distractor-frequency effect disappears when distractors are masked or preexposed. These findings were taken to refute…

The article "Is Google Making Us Stupid?" in last Summer's "Atlantic Monthly," raised a number of provocative, and indeed worrisome, questions about computer usage and cognitive development. For instance, persons with considerable experience of reading for the sake of pleasure report that, after a couple of years using computers a great deal, they…

This paper presents a cognitive account of both the advantages and disadvantages of direct manipulation interfaces, i.e., the use of icons to manipulate and interact directly with data rather than writing programs or calling on a set of statistical subroutines. Two underlying phenomena that give rise to the sensation of directness are identified.…

A software package, ThinkingLand, was developed to help students' understanding of the content and thinking processes involved when using multimedia. Topics include multimedia reports and knowledge building; journal writing; collaboration; procedural facilitations; and the design and instructional applications of ThinkingLand. (AEF)

Citing several reasons why computers offer the potential to enhance instruction, this paper suggests that the teaching of thinking skills should be integrated into various subject areas by using software programs that involve the use of the skills required in the particular subject area. To illustrate this matching strategy, three software…

Idea processors are computer programs that can aid the user in creating outlines by allowing the user to move, reorder, renumber, expand upon, or delete entries with a push of a button. The question is whether these programs are useful and should be offered to students. Theoretically, an idea processor prioritizes ideas by placing them in a…

The point of Choi and Clark (2006) was that after many well-designed studies, they have no evidence for either the learning or the motivational benefits of pedagogical agents. In their study, they found compelling evidence that when agents are found to enhance learning, a less expensive and less distracting pedagogical method has equal or greater…

Artificial intelligence, or the study of ideas that enable computers to be intelligent, is discussed in terms of what it is, what it has done, what it can do, and how it may affect the teaching of tomorrow. An extensive overview of artificial intelligence examines its goals and applications and types of artificial intelligence including (1) expert…

This paper discusses a model of information storage and retrieval, the k-d tree (Bentley, 1975), a binary, hierarchical tree with multiple associate terms, which has been explored in computer research, and it is suggested that this model could be useful for describing human cognition. Included are two models of human long-term memory--networks and…

This report incorporates a literature review, a workshop paper, and discussion by workshop participants on the current status of research on what the users of computer systems know, and how these different forms of knowledge fit together in learning and performance. It is noted that such research is important to the problem of designing systems…

In an increasingly technological society, there is a social need for designing communication technology around the perceptual abilities and cognitive strategies of people. A growing demand for information has created additional pressure on emerging communication technologies to provide electronic alternatives to the printed page. Design depends…

The concept of "structured programming" was developed to facilitate software production, but it has not carried over to documentation design. Two concepts of structure are relevant to user documentation for computer programs. The first is based on programming techniques that emphasize decomposition of tasks into discrete modules, while the second…

Discusses how computers can "converse" with students for teaching purposes, demonstrates how these interactions are becoming more complex, and explains how the computer's role is becoming more "human" in giving intelligent responses to students. (HOD)

Reviews basic ideas presented in this special issue on the evolution of behaviorism. Topics addressed include stimulus and response; research with animals; applications to education and training; human motivation; theory through computer programs; experimental analysis of behavior; behaviorism moving into other disciplines; cognitive…

Word processing programs offer five capabilities that can help students over the physical and psychological constraints associated with writing. First, producing text on a word processor is more tentative and more noncommital than producing text on paper. This reassures the writer that it is all right to experiment with words. Second, the blinking…
