According to the Multiple Deficit Model, comorbidity results when the genetic and environmental risk factors that increase the liability for a disorder are domain-general. In order to explore the role of domain-general etiological risk factors in the co-occurrence of learning-related difficulties, the current meta-analysis compiled 38 studies of…

In order to reach gender equity in the gifted population, an affirmative action policy was instituted in Israel to increase the number of girls identified as gifted. The purpose of this study was to compare the self-efficacy beliefs of girls in the top 1.5% (gifted girls (GG)) with those of girls in the top 3% (GG in affirmative action). It was…

Within contemporary developmental science, models derived from relational developmental systems (RDS) metatheory emphasize that the basic process of human development involves mutually-influential relations, termed developmental regulations, between the developing individual and his or her complex and changing physical, social, and cultural…

Two prospective studies examined a theoretical model wherein exposure to victimization, resulting from early behavioral risk, heightens children's social alienation and subsequent deviant peer affiliation (DPA). Across Study 1 (298 girls, 287 boys; K-7th grade; 5-12 years) and Study 2 (338 girls, 298 boys; 2nd-6th grade; 8-12 years),…

Attachment theory provides a frame for understanding the role of attachment styles in the development of bullying behaviour in adolescence.

A total of 1,921 students (1,006 girls and…

Adolescents' perceptions of peers' relational characteristics (e.g., support, trustworthiness) were examined for subtypes of youth who evidenced chronic maladaptive behavior, chronic peer group rejection, or combinations of these risk factors. Growth mixture modeling was used to identify subgroups of participants within a normative…

We tested whether gender-specific vs. common classroom norms were more powerful moderators of the association between a risk factor (rejection) and peer victimization among girls and boys. The participants were 1220 elementary schoolchildren from grades 4-6 (with 10-13 years of age). We compared different multilevel models including combined vs.…

Age and ethnic group differences in cold weather and contagion or germ theories of infectious disease were explored in two studies. A cold weather theory was frequently invoked to explain colds and to a lesser extent flu but became less prominent with age as children gained command of a germ theory of disease. Explanations of how contact with…

Suicide among preadolescents is a relatively rare phenomenon. Due to the infrequency of suicide among this population, this area of study has received limited investigation relative to suicide in other age groups and populations. This article reviews research related to suicide among preadolescents, defined as children under the age of 13. The…

We examined associations between adolescent problem trajectories and suicide risk outcomes in 361 community participants. Depressive symptoms (self-report) and externalizing behaviors (parent report) were assessed six times from grades 5 to 10. Parallel process linear growth curves indicated that lifetime suicide attempt history assessed to age 25…
