This study examined reciprocal-influence models of the association between relational self-views and peer stress during early adolescence. The first model posited that adolescents with negative self-views disengage from peers, creating stress in their relationships. The second model posited that exposure to peer stress fosters social…

This study examined the extent to which continuities and discontinuities in cognitive performance between ages 5 and 10 predicted adult income, educational success, household worklessness, criminality, teen parenthood, smoking, and depression. Assessed were the degree of this change during middle childhood, the influence of socioeconomic status…

Data from 918 children from the National Institute of Child Health and Human Development (NICHD) Study of Early Child Care were examined to test the interrelation of attachment and attentional performance and 2 known risks for poor attentional performance: male gender and social-contextual adversity. Attachment was measured using the Strange…

The study of the behaviour profile in subjects with Prader-Willi Syndrome (PWS). A total of fifty-eight 3- to 29-year-old subjects with PWS were studied using a standardized parent report of behavioural and emotional disturbances. There was an increase of behavioural and emotional disturbances for the adolescent and young adult age range, whereas…

In this study we examined the role of anxiety on novices' performance on the psychomotor task of rifle marksmanship. The stages-of-skill-development model suggests that aptitude influences performance while learning a skill; however, the model does not address the role of affect. Assessments for state anxiety and state worry were administered to…

Two studies were carried out during university workshops, and analyzed the effects of resource interdependence on student-student interactions, and the impact of these interactions on performance. Students worked cooperatively, either on complementary information (positive resource interdependence) or on identical information (resource…

Using the pooled 1998-2000 GSS data, this study examines what kinds of parents tend to select non-public schools for their children, a question that is fundamental but lacks direct, adequate answers in the literature. The results of logistic regression analysis show that religion, socio-economic status, age, nativity, number of children and region…

The primary purpose of this study was to examine the relationship of teacher retention to teacher education programs and state-mandated teacher certification examinations (PD exam). Identified participants completed either a traditional field-based teacher education program or emergency permit program and had passed a professional development…

Social cognitive theory suggests that self-constructs are better predictors when the specificity levels of self-constructs (as predictors) and the criterion variable closely correspond. In this study it was examined whether self-constructs measured at an intermediate level of specificity better correspond with the criterion variable (course…

Using a longitudinal design, we investigated the relation of childhood personality type to volunteering during adolescence. We hypothesized that participants with more adaptive personality functioning during childhood would be more likely to volunteer during adolescence and that membership in social organizations would mediate the relation of…

Using previously unreleased data on nearly every authorized work stoppage that occurred between 1984 and 2002, this paper tests whether the positive wage-strike relationship held following the breakdown of the post-war labor-capital accord. Unlike in decades past, these findings indicate a complete decoupling of the wage-strike relationship. Even…

There is a widespread belief that high-quality early care and education can improve children's school readiness. However, debate continues about the essential elements of a high-quality experience, about whether quality means the same things across different types of care settings, about how to measure quality, and about the level of quality that…

If pressed to provide a predictor of academic success, most people would choose socioeconomic status (SES). SES is a strong predictor when one looks at averages, but everyone knows that there are individual students of high wealth who are academic disasters and students of low wealth who are academic marvels. Wayne Hoy and colleagues, in numerous…

It is often of interest to estimate partial or semipartial correlation coefficients as indexes of the linear association between 2 variables after partialing one or both for the influence of covariates. Squaring these coefficients expresses the proportion of variance in 1 variable explained by the other variable after controlling for covariates.…

College admissions tests predict college performance well, particularly first year grade point average (GPA; Kuncel, Hezlett, & Ones, 2001, 2004). However, noncognitive measures may add to the incremental validity of cognitive measures in that they will assess a broader range of college performance dimensions and reduce racial subgroup differences…
