Mobile phones and other wireless devices that produce electromagnetic fields (EMF) and pulsed radiofrequency radiation (RFR) are widely documented to cause potentially harmful health impacts that can be detrimental to young people. New epigenetic studies are profiled in this review to account for some neurodevelopmental and neurobehavioral changes…

This longitudinal study compared immigrant and native adolescents' expectations concerning the timing of conventional socially acceptable and oppositional less socially acceptable forms of autonomy. Based on normative development and a collectivist background among immigrants, both developmental and acculturative change was expected. The sample…

"Interpersonal" rejection and "intergroup" exclusion in childhood reflect different, but complementary, aspects of child development. Interpersonal rejection focuses on individual differences in personality traits, such as wariness and being fearful, to explain bully-victim relationships. In contrast, intergroup exclusion focuses on how in-group…

The over-time reciprocal links between parenting and adolescent adjustment were examined in a sample of 1,354 serious adolescent offenders followed for 3 years (16 years of age at baseline, SD = 1.14). Parallel processing growth curve models provided independent estimates of the impact of parenting on adolescent functioning as well as the impact…

Trajectories in bullying through adolescence were studied along with individual, family, and peer relationship factors. At the outset, participants' ages ranged from 10 to 14; 74% identified as European Canadian with the remainder from diverse backgrounds. With 8 waves of data over 7 years, 871 students (466 girls and 405 boys) were studied to…

This study examined the role of adolescent perceptions of parental behavior and disrupted parenting in the continuity of antisocial behavior across generations. Participants included 430 adolescents and their biological parents assessed during the period from the 9th to 12th grades (9th grade age in years: M=15.09, SD=0.43). Structural equation…

To characterize cognitive maturation through adolescence, processing speed, voluntary response suppression, and spatial working memory were measured in 8- to 30-year-old (N=245) healthy participants using oculomotor tasks. Development progressed with a steep initial improvement in performance followed by stabilization in adolescence. Adult-level…

Developed and validated Parents of Adolescents Separation Anxiety Scale with parents of sixth, eighth, tenth, and twelfth graders, and college freshmen and seniors. Factor analyses supported two subscales: Anxiety about Adolescent Distancing (AAD) and Comfort with Secure Base Role (CSBR); both showed distinctive change patterns with child age.…

Adolescent adjustment measures may be related to each other and to the social environment in various ways. Are these relationships similar in genetic and environmental sources of covariation, or different? A multivariate behaviorgenetic analysis was made of 6 adjustment and 3 treatment composites from the study Nonshared Environment in Adolescent…

Latent growth models estimated developmental trajectories for adolescents' math and English self-perceptions (perceived talent, success expectancies), values (intrinsic, utility) and task perceptions (task difficulty, effort required). A longitudinal cohort-sequential study included 1,323 participants spanning Grades 7 to 11, with Occasion 1 mean…

Examined factor structure of the emotional Autonomy Scale (EAS) in 3 samples of adolescents, with each sample consisting of 3 racial/ethnic groups. Found that the EAS exhibited poor construct validity and behaved quite differently for different grade and ethnic groups. Suggested that the most credible solution may be to reexamine the conceptual…

Examined impact of experimentally altering mothers' style when discussing sexuality and AIDS with adolescent children. Found that intervention group mothers reduced their amount of speaking, asked more open-ended questions, acted less judgmental, and discussed dating and sexuality more than did control group mothers. Intervention group adolescents…
