In this article, 41 models of covariation detection from 2 x 2 contingency tables were evaluated against past data in the literature and against data from new experiments. A new model was also included based on a limiting case of the normative phi-coefficient under an extreme rarity assumption, which has been shown to be an important factor in…

Using 6 longitudinal data sets, the authors estimate links between three key elements of school readiness--school-entry academic, attention, and socioemotional skills--and later school reading and math achievement. In an effort to isolate the effects of these school-entry skills, the authors ensured that most of their regression models control for…

The Non-Cognitive Questionnaire (NCQ) is a 23-item measure assessing eight noncognitive variables that are thought to predict the performance and retention of students in college. The NCQ is widely used in research and practice. This study is a meta-analytic review of the validity of scores on the NCQ across 47 independent samples for predicting…

Researchers have suggested that transformational leadership is an important aspect of effective schools; however, whether the effects vary across related studies and the robustness of the overall effect size remain unclear. A meta-analysis technique was used to synthesize the results of 28 independent studies and to investigate the overall…

Procrastination is a prevalent and pernicious form of self-regulatory failure that is not entirely understood. Hence, the relevant conceptual, theoretical, and empirical work is reviewed, drawing upon correlational, experimental, and qualitative findings. A meta-analysis of procrastination's possible causes and effects, based on 691 correlations,…

We report two studies examining the relations among three paired-associate learning (PAL) tasks (visual-visual, verbal-verbal, and visual-verbal), phoneme deletion, and single-word and nonword reading ability. Correlations between the PAL tasks and reading were strongest for the visual-verbal task. Path analyses showed that both phoneme deletion…

This report uses meta-analysis to derive correlations between the variables of teacher immediacy, cognitive learning, and affective learning. A model was constructed such that the perception of teacher immediacy, a behavior, generates an intermediate outcome of affect, a motivation, which in turn increases cognitive learning outcome. The data…

Researchers have found that students with learning disabilities (LD) obtain statistically higher scores on measures of depression than their peers without LD. However, what is not known is whether students with LD display greater levels of clinical depression than their peers without LD. If they do, then special education services should address…

There is a change in false belief task performance across the 3-5 year age range, as confirmed in a recent meta-analysis [Wellman, H. M., Cross, D., & Watson, J. (2001). Meta-analysis of theory mind development: The truth about false-belief. "Child Development," 72, 655-684]. This meta-analysis identified several performance factors influencing…

A meta-analysis (k of conditions = 128; N = 4,598) examined the influence of factors present at the time an attitude is formed on the degree to which this attitude guides future behavior. The findings indicated that attitudes correlated with a future behavior more strongly when they were easy to recall (accessible) and stable over time. Because of…

For over 15 years, masked phonological priming effects have been offered as evidence that phonology plays a leading role in visual word recognition. The existence of these effects--along with their theoretical implications--has, however, been disputed. The authors present three sources of evidence relevant to an assessment of the existence and…

Meta-analytic techniques were used to analyze data from a collection of school psychologist job satisfaction studies that were conducted between 1982 and 1999. Eight studies, all of which used the Modified Minnesota Satisfaction Questionnaire (m-MSQ) to measure job satisfaction among school psychologists, were included in the analysis. Two…

In their reply to our article, Greenwald, Rudman, Nosek, and Zayas offered comments on the use of their procedure relative to one that focuses on standard multiple regression (SMR) methods). Here we address five issues where we think a balance of perspective is called for: (a) issues of measurement, (b) the structuring and reporting of the…

The American Psychological Association and many other professional mental health organizations require graduate programs to provide education in multicultural issues. However, the effectiveness of multicultural education has been debated in the literature over the past several years. The overall purpose of this study was to examine the…

There has been little attempt to relate well-known educational approaches in autism to increased psychological understanding about the condition. This paper addresses that gap. Four discrete educational approaches to autism (Higashi, Lovaas, Option, TEACCH), and two "eclectic" approaches (SPELL, one LEA specific), are explored within the context…
