The authors examined the construct and incremental validity of the Interpersonal Measure of Psychopathy (IM-P), a relatively new instrument designed to detect interpersonal behaviors associated with psychopathy. Observers of videotaped Psychopathy Checklist-Revised (PCL-R) interviews rated male prisoners (N = 93) on the IM-P. The IM-P correlated…

Objective: To test for gene-environment interaction with depressive symptoms and family conflict. Specifically, to first examine whether the influence of family conflict in predicting depressive symptoms is increased in individuals at genetic risk of depression. Second, to test whether the genetic component of variance in depressive symptoms…

Background: Family history of mood disorders and stressful life events are both established risk factors for childhood depression. However, the role of mediators in risk trajectories, which are potential targets for intervention, remains understudied. To date, there have been no investigations of mediating relationships between risk factors and…

Background: An inhibition deficit, including poor interference control, has been implicated as one of the core deficits in AD/HD. Interference control is clinically measured by the Stroop Colour-Word Task. The aim of this meta-analysis was to investigate the strength of an interference deficit in AD/HD as measured by the Stroop Colour-Word Task…

The reliability and stability of Elementary Reading Attitude Survey (ERAS) scores were examined for the recreational and academic subscales and for the total scale. The responses of 718 students in fourth, fifth, and sixth grades were included in the analyses. A seven-day interval between testings was used. The recreational and academic subscale…

This study used a diagnostic testing approach to compare the mathematics achievement of eighth-grade students across a sample of 20 countries, analyzing data from the Third International Math and Science Study-Revised (TIMSS-R, 1999). Using the rule-space method, student mastery was measured on 23 specific content knowledge and processing…

This study investigated the possible impact of a science teaching methods course on pre-service teachers' self-efficacy and perceptions of self as science teachers. The study also investigated the probable relationship between these two variables, which both measure issues related to the expected behaviour teachers adopt when teaching science.…

This study analyzed the effects of online formative and summative assessment materials on undergraduates' experiences with attention to learners' testing behaviors (e.g., performance, study habits) and beliefs (e.g., test anxiety, perceived test threat). The results revealed no detriment to students' perceptions of tests or performances on tests…

This study tracks the development of cognitive academic language proficiency of 47 academically competent high school ESL learners of differing age on arrival (AOA) who received instructed ESL support and one comparison group of six young arrivals who received little if any ESL support during their educational experiences. Although intake and…

The quest for perfection has been anecdotally associated with great achievement and despair; with adjustment and maladjustment. No population has more frequently been associated with perfectionism than the gifted. This study was designed to (i) identify the types of perfectionism observed in a sample of Australian school students, and (ii) to…

The purpose of this investigation was two-fold: (1) to gather descriptive information in the areas of salient student characteristics, level of participation in general education classes, current level of functioning, and student outcomes (e.g., GPAs, performance on state or national exams) for students with disabilities (SWDs) in high school…

Under the No Child Left Behind Act (NCLB), every school is subject to the controversial mandates for annual test score gains contained in the federal law. The law represents a profound change in the relationship between the federal government and state and local education agencies regarding who controls education and has direct implications for…

Data from 104 undergraduate and 83 faculty/staff women indicated that perceived sexist events, measured by the Schedule of Sexist Events Scale (SSE), along with Passive Acceptance (PA), Revelation (R), and Embeddedness-Emanation (EE) attitudes, measured by the Feminist Identity Development Scale (FIDS), each related positively to women's…

In this article, the authors describe a collaborative effort involving 30 school districts in California's Silicon Valley that are seeking to overcome the ill effects of mandatory high-stakes standardized testing in mathematics. These districts administer, score, and analyze a common set of performance assessments in mathematics in a way that…

In this study, the authors plotted the Spanish language usage of 10 preschool-age children over the course of 3 years and assigned them to one of two groups: language maintenance and language loss. The authors then compared the groups' scores on structured tasks, language behaviors, and language usage/exposure variables. They found that children…
