This investigation examines the extent to which characteristics of the teacher-child relationship (closeness, dependency, and conflict) are predictive of changes in children's peer victimization and aggressive behavior over the course of a school year. Relational and physical forms of victimization and aggression were studied, and changes in peer…

One pressing issue facing parenting interventions for disruptive behaviors of young children is forecasting who will benefit from participation. The purpose of this study was to examine four personal and interpersonal predictors (i.e., parent depressive symptoms, parent education, coparent conflict, and marital status) of engagement (i.e., number…

DSM-IV distinguishes two symptom domains of attention deficit hyperactivity disorder (ADHD): inattentiveness and hyperactivity-impulsivity. The present study examines the aetiologies and developmental relations underlying the associations between inattentiveness and hyperactivity-impulsivity over time, based on a representative population sample…

Background: Identifying how genetic risk interacts with experience to predict psychopathology is an important step toward understanding the etiology of mental health problems. Few studies have examined genetic risk by experience interaction (GxE) in the development of childhood psychopathology. Methods: We used both co-twin and parent mental…

Continuity and intergenerational transmission of representations of attachment were examined in a longitudinal sample of 88 Mexican immigrant mothers and their children who participated in the local intervention group of the Early Head Start Evaluation Study. The authors interviewed mothers with the Adult Attachment Interview (AAI) and Parent…

This research investigates the ability of adult proficient readers to predict words that have been fully or partially deleted, without being able to read what came after the blank. Predictions were analyzed for accuracy and if inaccurate for their grammatical nature, syntactic and semantic acceptability, and retention of the author's meaning.…

Early social-emotional development occurs in the context of parenting, particularly via processes such as maternal emotion socialization and parent-child interactions. Results from structural equation modeling indicated that maternal contingent responsiveness partially mediated the relationship between maternal emotion socialization of toddlers (N…

This study examined the effects of motivation to learn science, science self-beliefs, and science instructional practices on science achievement of 13,985 15-year-old students from 431 schools across Canada. Hierarchical linear modeling (HLM) analyses, while controlling for student- and school-level demographic characteristics, revealed the…

Understanding key foundational principles is vital to learning chemistry across different contexts. One such foundational principle is the acid/base behavior of molecules. In the general chemistry sequence, the Bronsted-Lowry theory is stressed, because it lends itself well to studying equilibrium and kinetics. However, the Lewis theory of…

The development of the Chemistry Competence Test was prompted by the extensive curriculum changes in the South African school system after democracy was established in 1994. As chemists, we were concerned that there might be a lack of articulation between secondary and tertiary levels, since we anticipated that curriculum changes would have an…

The present study investigated associations between maternal relationship instability patterns and children's behavioral and emotional functioning in middle childhood in a representative sample of low-income urban families (N = 891). Data from the "Three-City Study" tracked maternal partnerships through the child's life, assessing total marital…

Studies of brain development suggest that the increase in risk taking observed during adolescence may be due to insufficient prefrontal executive function compared to a more rapidly developing subcortical motivation system. We examined executive function as assessed by working memory ability in a community sample of youth (n = 387, ages 10 to 12…

Risk for peer victimization varies by ethnicity, but few studies explore how the ethnic context of the school can affect this. Using a large sample of schools and high school students, we used hierarchical linear modeling to explore victimization risk by ethnicity within the ethnic context of the school. Models predicted total, physical, verbal,…

This study examined the association between relationship styles, coping strategies, and psychological distress among 144 Anglo-Australian and 250 Hong Kong Chinese undergraduate students. The results indicated that relationship styles (secure, clingy, and fickle) influenced psychological distress through their association with coping strategies…

Purpose: Social software usage is growing at an exponential rate among the present generation of students. Yet, there is paucity of empirical study to understand the determinant of its use in the present setting of this study. This study, therefore, seeks to investigate factors that predict students' attitudes and intentions to use this…
