Teaching students to use specific details is perhaps the college writing teacher's most troublesome job. Much time and effort is wasted by marking students' papers with comments such as "specify,""details,""illustrate," or "demonstrate." Significant concrete details should occur to a writer before the generalization does, since the best kind of…

Several observations about the way humans conceive of attributes, changes, and covariation of stimuli are presented as indications for the existence of a conceptual hierarchy of dimensions in which time dominates space, and space dominates every other dimension. (Author)

Results show that basic objects are shown to be the most inclusive categories for which a concrete image of the category as a whole can be formed, to be the first categorizations made during perception of the environment and to be the categories most codable, most coded, and most necessary in language.

Two models for teaching people to think, the Deweyan problem-solving model and the traditional discipline-oriented model, are described and evaluated. (GW)

Analysis of the mental factors of seventh grade students indicates that numerical facility and perceptual speed are a single factor at this age level and that no purely verbal factor exists. Seven clearly differentiated factors are found for males and five for females. (Author/WY)

Discussed are the concepts of intuition, the general properties of an intuitive knowledge, and the classification of intuitions as problem solving of affirmative. An example of intuition using multiplication and division is described in some detail. (MNS)

A brief survey of models in dealing with various types of understanding is given. Then a hybrid model, which proved inadequate for describing understanding, is outlined. Finally, four levels of understanding are discussed: intuitive, procedural, abstract, and formal. The concept of number is used to illustrate these levels. (MNS)

Descries professional overspecialization and education's overemphasis on the acquisition of formalized information. Discusses the capabilities of the hemispheres of the brain and the problems caused by focusing on only the left hemisphere. Illustrates intuition and abstract patterns. Suggests that recognition of laterality will advance education…

Results indicated that progress through adolescence leads to greater differentiation, abstraction, and integration. The emergence of the ability to abstract was considered the most important cognitive development in the adolescent's self-system. Major transformations appeared after age 15. (Author/DB)

Twelve students with autism and 12 with mental retardation, who had passed a first-order test of false belief, were given a second-order reasoning task. No intergroup performance differences were seen. Findings suggest that the difficulty for both groups with the second-order task lies in information processing demands rather than conceptual…

Comments on Flavell's paper (PS 522 962) presented in the same issue. Stresses some of the positive aspects of preschoolers' conception of thinking, and raises questions about the relatively negative portrait of young child's introspective abilities. Discusses evidence of introspection among preschoolers, and underlines the special, and…

Comments on Flavell's paper in this issue. Examines the paper's findings on three different aspects of children's knowledge about thinking: their ability to differentiate thinking from other activities, their awareness that thinking is always going on in people's minds, and their capacity for introspection into their own thinking. Argues that…

Investigates 10-year-old children's abilities to reason by analogy in solving addition and subtraction comparison problems involving unknown compare sets and unknown reference sets. Children responded in a consistent manner to the tasks involving the basic addition problems, indicating substantial relational knowledge of these but responded in an…
