A theory of cognitive modifiability deals with the phenomenon of low cognitive performance, explains its etiology, and forms the basis for a remedial intervention--Instrumental Enrichment (IE)--that induces changes of a structural nature in adolescents. (Author)

Among findings of the study involving 10 autistic children (8 to 15 years old) were that four adult approach styles (varying in structure and interpersonal demands) were reliably discriminable and that children's responses were positively related to the interpersonal and task oriented demands that were made of them. (Author)

A comprehensive three-year process for planning a system of teacher accountability can ensure discriminating and valid results. (Author)

The article describes how teachers can screen their severely handicapped students for allergies which, if untreated, can produce reactions that interfere with ability to attend to instruction. (Author/CL)

Thirteen intrinsic and extrinsic uncorrelated (orthogonal) factors related to academic performance of hearing impaired children integrated into regular classes are identified and described. The factors are discussed in terms of their implications for determining the suitability of a mainstream setting for a particular hearing impaired child.…

The efficacy of blood doping (infusion of blood into an athlete's circulatory system) has not been established and merits further research. (JD)

The efficacy of steroids in development of muscular strength in athletes is not proven. Their long-term use is increasingly being associated with liver disorders, including liver cancer, and other health problems. (JD)

The predictive ability of 10 developmental variables measured at age five to predict academic achievement at the end of first grade was studied with 40 Head Start children. (Author)

Reviews the literature on course attrition relevant to: factors contributing to course attrition, non-punitive grading, open entry/open exit courses, lack of non-credit options, reasons for withdrawal, curriculum areas with low course completion rates, programs and proposals for reducing attrition, evaluating non-credit students, and student…

To facilitate appropriate line choice for tactile graphic displays, 42 visually impaired Ss traced four types of tactile lines in a simple display (without intersections), and in a complex display (having intersections). (Author)

This study shows a consistent tendency to underestimate the finishing times of first- and second-time marathon runners. (MM)

Vocational Preference Inventory (VPI) was used to discriminate counselors rated as highly effective, as average, or as ineffective. Results indicated significant correlations between tested personality characteristics and rated job performances. Employment level, sex, age, certification, and degree status were of no significance in predicting…
