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)

To determine whether infants can form face expression categories, groups of infants 18 to 24 weeks old, along with those 30 weeks old, were habituated by the infant control procedure to photographs of four different female faces, each with an identical expression (happiness or surprise). Results are discussed in terms of age and sex differences.…

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)

Two experiments were performed to determine whether practice on less complex problems, either smaller size or in familiar context, produces a strategy that transfers to similar but more complex problems. Practice on familiar problems was no more effective than practice on unfamiliar for transfer to another unfamiliar context for all sizes. (Author)

Three training methods differing in degree of abstraction (demonstration, slide-diagram, and diagram) were used to instruct adolescents (26 control and 21 aphasic) in the completion of two tasks. Results indicated that aphasics have a deficit of abstract thinking which can prove a handicap in training situations. Ten sources are cited. (EJS)

This study focuses on the use of parables, proverbs, and metaphors as codifications in an educational program in rural Zaire. Its thesis is that Freire's concept of codification has tremendous conceptual power for transforming perspectives and providing hope in the face of dominance. (CT)

Possible legal justifications for "reasons"--statements that justify conclusions--are discussed. It is suggested that justification is a concept that should be taken seriously and is one that is guided by objective standards, authority, tautology, tradition, consequences, comparison, intuitive moral sense, internal consistency, determinism, or…

Nihilism is the fundamental movement in the history of the West. Materialism is a symptom of nihilism. Materialism is the view that all meaning has gone from the cosmos, nature, and culture. Values are objective, explicit options which imply the existence of choice. (JN)

Seven-year-olds and university students were questioned about hidden or visible colored counters. Under certain testing conditions, the children were able to demonstrate one of the major characteristics of formal operational thought, namely the ability to reason in terms of verbally stated hypotheses without reliance on direct, physical…

Details a study that assessed two experimental approaches to improving reading comprehension among fourth grade children--one involving training in syllogistic reasoning and the other using comprehension questions--and concludes that neither approach was effective. (FL)

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)

A framework for using and changing concepts in the study of science is described. (JD)
