A motor performance typology of boys and girls (ages 6-10 years) was developed, based on four factors extracted by factor analysis from data on 47 physical growth and motor performance variables. Nineteen variables which best described the four factor-defined components were used in formulating the person-clusters (typologies) following Tryon's…

This investigation sought to determine whether the excellent performer evolves from typical material through training or if he brings facilitating characteristics with him to practice on the first day. Subjects were highly successful AAU age-group competitors who had invested at least 50 percent of their lives in swim training. These seven female…

Previous work supports the hypothesis that cardioidal strain offers a plausible mathematical model for the perceived changes in human craniofacial morphology due to growth. In two experiments, cardioidal strain caused changes in the perceived age of nonhuman profiles similar to those produced on human faces in earlier work. (Author/MH)

Childhood obesity starts at a very early age, and preventive measures taken early enough may retard the development of fat cells. It appears that physical activity plays an important role in reducing obesity. The activity program must start early, in preschool days. It is felt that screening children for obesity when they first enter school and…

This annual report of the Yale Project describes the progress made on the nutrition and growth study of Tunisian children from September 1, 1971 through August 31, 1972. The report details: (1) the progress in analysis of the cross-sectional study data, which was completed as of June 30, 1972, and (2) the development of the present longitudinal…

The degree to which under nourishment exists in a local community such as San Diego, California, and in the U.S. at large, and whether it is severe enough to interfere with brain development is the focus of this report. After establishing criteria for nutrition intake that would represent unambiguous jeopardy to brain development, these criteria…

The efficacy of second dentition, the number of erupted teeth, as an index in assessing school readiness was examined. A series of cognitive, achievement, and social-emotional instruments were administered to a group of 41 first- and 43 second-grade children. The tests used in this study were: Devereux Elementary School Behavior Rating Scale,…

This interim report of the Yale Project describes the progress made on the nutrition and growth study of Tunisian children from September 1, 1972 through February 28, 1973. A major part of the report is devoted to the organizational and data collection problems of the longitudinal study, discussed under the following categories: biomedics,…

Contemporary theories of perceptual-motor development and dysfunction are analyzed in detail in this review of the literature. Studies focused on observation of delays, deviations, cause, theories of development, and programs of remediation. It is suggested that it may be presumptuous for theorists to delineate three, four, or ten characteristics…

This booklet pertains to the size and the form of the human body in infancy, childhood, adolescence, and adulthood. Historic and current information is presented for individuals in population groups of the Americas, Europe, Asia, Africa, and the Pacific. Differences in size and growth patterns between urban and rural individuals of the same racial…
