Background: Intervention models to promote healthy adolescent development highlight the importance of developmentally appropriate practice (DAP); however, scant resources identifying DAP in relation to the relevant research are available. With the increased professionalization of youth work and the expanding research on adolescent development,…

Autistic regression is one of the many mysteries in the developmental course of autism and pervasive developmental disorders not otherwise specified (PDD-NOS). Various definitions of this phenomenon have been used, further clouding the study of the topic. Despite this problem, some efforts at establishing prevalence have been made. The purpose of…

The assumptions about children's development are challenged by recent research findings that show learning begins at an earlier age and proceeds at a different pace than expected. Sometimes researchers find that they have misunderstood children's cognitive, social, and physical development due to errors in measurement (faulty tests or tools),…

This study aimed to determine whether self-assessed puberty is sufficiently reliable and valid to substitute for physician examination when feasibility of physician examination is low (e.g., behavioral research). Adolescents (convenience sample N = 178 endocrinology patients and N = 125 from educational trial; mean age 12.7 and 11.3 years,…

Learning, beginning in infancy, depends chiefly upon the nature and quality of movement experiences. Since 50 percent of a child's potential for learning is developed by age five, it is essential that movement programs be devised for children of preschool age. Movement programs must be geared to the individual child's developmental level. (JN)

This paper will present evidence to support ontogenetic and phylogenetic parallels and draw from these comparisons to further illuminate our understanding of micro and macro human development. Individual and collective stages of physical, psychological and spiritual development will be compared and their homologous structures examined.…
