Focuses on some apparently evolved features of human adolescence and their possible functions, including the pubertal growth spurt, sexual size dimorphism and bimaturism, the greater aggressiveness of males, heightened concern with one's social standing and the factors affecting it, intergenerational friction, same-sex aggregations and solidarity,…

Although research indicates that the growth and development of young athletes is not adversely affected by continuous rigorous physical activity, there is evidence to support the fact that inclusion of certain nutritional programs may deplete the physically active child. Cardiovascular involvement should be monitored and proper safeguards taken to…

Neonates born without complications to healthy mothers at 14,000 feet or at 490 feet above sea level were evaluated at 24-36- and 48-60-hours-of-life. In comparison with low-altitude infants, high-altitude infants were significantly lighter, shorter, had a smaller arm circumference, and presented more signs of behavioral immaturity in interactive…

The positiveness of self-concept and self-esteem of Mexican American and Anglo students in grades 3 through 8 was assessed in physical maturity, peer relations, academic success, and school adaptiveness. While self-concept and self-esteem changed across grades, there was no evidence of different developmental patterns for the two groups.…

Analyses were made of the pattern and frequency of mothers' visits to the intensive care nursery for premature infants. Visiting was found to be uncorrelated with medical, socioeconomic, or demographic variables, but was apparently related to significantly higher state levels achieved by infants who received a program of early stimulation.…

Maintains that males and females have physiological and psychological differences which cause differences in perception and learning patterns, and that educational and curricular approaches should be geared to those differences. (CM)

Allergies have recently been related to the development of speech, language, and hearing problems in students. Diagnosis and treatment is compounded by multiple complaints or the absence of complaints. (Authors/CJ)

Critical factors in the selection of calipers for skinfold measurements to assess body fat percentage in children and considerations for the training of testers in their proper use are highlighted. (JMF)

This study investigated the relationship of physical manifestations of sex hormone influence to cognitive functioning in a longitudinal sample of 106 adolescent males and 99 females (ages 13, 16, and 18 years). Analyses of the 35 males and 40 females who had all cognitive and physical data at all three ages are reported here. (Author/SB)

Compares height, weight, and triceps skinfold of Mexican American (MA) children, ages 10-14, in Texas with reference data on American children. Heights were below reference means while weights about same. Boys' triceps skinfold measurements were significantly greater than means. Girls' were similar, indicating positive energy balance. (Author/TES)

Presents data from two studies determining the validity of various measures of physical activity in preschool children. One explored how certain measures of activity predicted observed behavior. The other examined the Caltrac motion sensor's predictive validity. Results indicate the Caltrac monitor is sensitive to children's individual differences…

Explains how martial arts, specifically karate, can benefit today's youth. States that karate promotes physical fitness, and also helps students learn to relax and calm their bodies, develop strong mind/body connections, and enhance mental calmness.

Eighteen boys with fragile X syndrome were compared with 42 with idiopathic intellectual disability, and 45 with Down syndrome. Boys with Down syndrome had more sensory problems and smaller head circumferences than normal. Head circumferences of boys with fragile X syndrome and with idiopathic intellectual disability were larger than normal.…

Notes that scientists understand in greater detail the various anatomical and neurological changes that allow children to develop motor and sensory abilities. Explores how the research findings are calling into question the notion of prescribed developmental milestones. (HTH)

Discusses the connection between brain development and human educational needs based on neuroscience research. Considers brain development from conception, including cell structure, myelination, and regional development of the brain, stressing the importance of a child's early environment and the prenatal vulnerability of the brain.
