This study evaluates the dimensions of fractional-size violin bows in relation to the anthropometric and grip-strength measurements of children and adults. In string education, various methods and devices have been put forward to measure children for the correct violin size, but there is a lack of research regarding the proper bow size. Results…

There is a virtual consensus regarding the types of language processes, interactions, and material supports that are central for young children to become proficient readers and writers (Shanahan et al., 2008). In this study, we examine these supports in both home and school contexts during children's critical transitional kindergarten year.…

Objective: A small literature suggests that ADHD may be associated with dysregulated growth, but this prior work primarily used clinically referred samples, so it faces difficulties of interpretation. The objective of this study is to sample the general French population for ADHD and evaluate if ADHD is associated with dysregulated growth.…

The Movement Assessment Battery for Children (M-ABC) is one of the most accepted tools, both in clinical practice and in research, for the diagnosis of Developmental Coordination Disorders (DCDs) in children. The present study aimed to: (1) establish the construct validity of M-ABC in Israel by comparing the motor performance of typically…

Discusses normative developmental changes in cardiovascular and electrodermal activity and describes the dynamic balance between branches of the autonomic nervous system. Issues for further developmental study are identified, and problems and limitations in the psychophysiological study of children are explored. (Author/RH)

The purpose of this paper is to provide information on child psychology and child development which could be useful to persons planning interpretive programs for children in public parks and recreation areas. Aspects of physical, cognitive and social developmental processes in children of different ages are described briefly and specific examples…

The physical advantages of competitive training programs for children are positive if physiological factors of growth and development are observed. Implications for training are discussed. (DF)

Compared Chinese fourth-, eighth-, and eleventh-graders' self-perceptions of ability in physical education. Found no grade-related decline in perceived ability. All students used effort, ability, and comparison to judge their ability. Students at all grades perceived task mastery as the major ability indicator and tended to assess ability in…

This study investigated the relationship between physical performance tests and body fatness in young children, and the extent to which differences in performance between the sexes could be explained by differences in body fatness. Measurements of age, height, weight, skinfold thicknesses, and performance scores on the vertical jump, standing…

This study was undertaken to compare the motor performance age and race differences between black and caucasian boys ages six to nine. One hundred and twenty subjects were administered 25 test items which measured (a) muscular strength, (b) muscular endurance, (c) cardio-respiratory endurance, (d) speed, (e) power, (f) agility, (g) balance, and…

A double blind, placebo controlled, crossover study using methylphenidate as a standard and two doses of imipramine was carried out in 30 hyperactive children (mean age 8.5 years). Particular emphasis was placed upon imipramine's action on cognitive function, physiological function, and self-esteem, and upon dosage effects. (MP)

To clarify patterns in the rate of motor development, children observed between kindergarten and second grade were refilmed, performing an overarm throw, when they became seventh-grade students. Results were compared with predictions made earlier. Differences in the skill levels of boys and girls and differences in their throwing experience are…

This study compared the body mass index (BMI) of 118 children with infantile autism with corresponding BMI percentiles in age-and sex-matched reference populations. The BMI distribution of the male children was significantly lower than that of the age-matched reference population. BMI was not associated with intelligence or socioeconomic status.…

Examined relations between children's temperament, ability overestimation, and accidental injuries. Found that watching peer failure on physical tasks was related to conservative ability judgments for same task. Surgency/Undercontrol was related to 6-year-olds' judgment accuracy and to 8-year-olds' decision times. Ability overestimation was…

Twelve studies examined implications of age-related changes in movement between 6 weeks and 52 years for various psychological domains. Findings indicate an inverted U-shaped pattern in limb movements per hour that peaked in middle childhood, later than expected. This pattern in motor activity has relevance for development, and for ADHD,…
