Self-reports of grade at first menstrual period for 1,967 fourth-grade through ninth-grade girls were used to categorize girls as early maturers. The categories of early maturer and other (on-time or late maturers) were then examined for stability over a 3-year period using McNemar tests and [kappa] coefficients. Although the results showed…

Dr. Sally Knipe, Course Coordinator, Bachelor of Education (Middle Schooling) at Charles Sturt University has been teaching undergraduate students in this program for six years. When Charles Sturt University introduced a learning management system, Interact she, with the faculty's educational designer, Miriam Edwards worked together in developing…

Using an "at-risk" sample of African American girls, the present study examined the link between girls' retrospective reports of pubertal timing, girls' perceived relative pubertal timing, and their behavioral and emotional problems as rated by the girls themselves (N = 102; 11-17 years), as well as teachers and parents. Structural equation…

Physical changes that occur during puberty alter the body image. Girls formerly had more difficulties accepting physical changes than boys. In this longitudinal study (three family visits; time interval: 1 year), pubertal development, body satisfaction, and desired body changes of 106 boys and 108 girls were assessed. The adolescents were between…

This study examined the relationship among pubertal timing, parental control, and problem behaviors. There were 267 participants, whose ages ranged from 9 to 16 years. Both maternal and paternal psychological control predicted problem behaviors over and above the effects of behavioral control. For boys, early maturation and high levels of paternal…

This article reports that educators are still searching for the right blend of academic and developmental strategies for middle school students. More than a decade after a prominent group of middle-grades reformers set out to infuse higher academic standards into what critics deemed the touchy-feely world of middle schools, many teachers are still…

Puberty culminates in a dramatic and visually apparent set of changes in each individual. Social and psychological effects of the meaning of these changes are an important component in understanding the significance of puberty for adolescents and their behavior. (CJ)

Compared hormone concentrations in 52 pre- and postmenarcheal girls to determine if they fit a dichotomous model of pubertal development surrounding menarche and to study methodological issues of variability in self-reports of menarche. Found discrepancies in reporting the age of menarche and great overlap in hormones between pre- and…

Recent studies have examined the prevalence of disordered eating and other health risk behaviors among adolescent boys and girls. However, these studies generally have not examined predictors of these behaviors, and have not embedded the investigations within a theoretical framework. This study employed a longitudinal design to evaluate the…

Adolescents have begun to initiate sexual activity at increasingly early ages in the past few decades. Using a sample of 2,494 adolescents from the National Longitudinal Survey of Youth (NLSY97), structural and parental process variables were examined in the prediction of sexual onset. Results indicated that the age at which youth initiate sexual…

Gene transcription is required for long-term memory (LTM) formation. LTM formation is impaired in a male-specific manner in mice lacking either of the two Ca[superscript 2+] / calmodulin-dependent kinase kinase ("Camkk") genes. Since altered transcription was suggested to cause these impairments in LTM formation, we used microarrays to screen for…

Life, in general, is a series of ever-increasing challenges. Ideally, the lessons learned from previous experiences prepare a person for future ones. That isn't always the case, particularly when puberty hits. Despite the many environmental and personal variables converging at the same time, schools can be instrumental in guiding teens through…

Individuation, a process whereby adolescents gain autonomy from their parents while maintaining emotional relatedness, is displayed by characteristic styles of verbal exchanges. Negotiating this developmental transition is often stressful for adolescents and their parents. This study deals with the association between pubertal timing,…

The objectives of this research were to explore patterns of heterosexual activity in early adolescence and to examine the differential pathways to light and heavy heterosexuality. We utilized the National Longitudinal Survey of Canadian Children and Youth (NLSCY) in which heterosexual behaviors, as well as puberty, parenting processes, peer…

This study examined the role of ego development, as measured with the Washington University sentence completion test, in the relationship between pubertal maturation and psychosocial adjustment (self-image and depression) in adolescent boys. The data consisted of 73 boys between 14 and 16 years of age. The results indicated that late maturing boys…
