In this article, I describe the 21 ideas underlying a 42-year search to understand giftedness. I present the ideas roughly chronologically, in the order in which they arose, and discuss how in a career as in science, progress means supplementing or even superseding one idea with the next. In terms of the 21 ideas, I start with a discussion of how…

Research in the development of teacher cognition and teaching performance in K-12 classrooms has identified consistent challenges and patterns of behavior that are congruent with the predictions of dual-process models of cognition. However, cognitive models of information processing are not often used to synthesize these results. This article…

Relationships between cognitive complexity as defined by the ITI [Interpersonal Topical Inventory (Tuckman, 1966) and the CST [Conceptual Systems Test (Harvey, 1967)] and a number of other information processing variables were examined using 107 grade eleven students. (Editor)

Article describes an approach which employs a structuring of the user's conceptual reference spaces into sets of "action primitives", peculiar to the type of computer-aided task involved. (Author)

Author stresses the importance of art, music, and literature experiences in the perceptual development of a child. (GB)

Experiments dealing with quantification processes in adults were run as part of an attempt to formulate an information processing model of cognitive development. The existence of three quantification operators--subitizing, counting and estimation--was first postulated. Experiments were then designed to refine the parameters which define the…

This study investigated the problem representations formed by college students while solving mathematics problems. Problem representation characteristics indicative of understanding were identified by analyzing audio-tapes and written work of sixteen subjects, ages 16 to 24, who solved mathematics problems using the think-aloud technique. These…

Examines findings of scientists and educators who have studied whole brain processes as a means of learning new information and skills. Applies this research to the classroom. (SRT)

In a task designed to separate perceptual processes from memory, reading-disabled 12-year-olds showed no perceptual deficits as compared to their peers. However, they exhibited major deficiencies in memory skills, appearing to suffer from a basic information-processing deficiency. (Author/CS)

The purpose of this article is to review and critique each of the research studies published in this special issue. We will critique each article, derive one or more instructional design heuristics based on the findings for each study, and provide recommendations for extending particular lines of research. Three suggestions are provided concerning…

It is argued that an area of linguistic research ripe for exploration is how the speaker actually makes use of linguistic knowledge in the production or reception of utterances. It is proposed that speech production is a lexically driven rather than semantically driven process and that the speaker's procedural competence is lexico-syntactic in…

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. (Author/CHC)

This study is a preliminary investigation of the relationship between measures of individual differences in perception and the way word components fuse when words such as "lanket" and "banket," both derived from "blanket," are presented one to each ear. Thirty-six native speakers of English participated in the experiment, receiving four dollars…

In this study retrospective verbal reports were collected in order to study cognitive processes activated when solving simple additions. The research was devoted to a revision and validation of the earlier presented process model (Svenson 1975) by using retrospective verbal reports as a complement to the response latencies analyzed earlier.…

The investigation reported is primarily a description of how college students solve or fail to solve algebra equations. Protocols were collected from two groups of college students; one group was expected to be good solvers, the other group contained many poor solvers. The investigators sought to identify and classify the difficulties students…
