Meta-analytic studies have concluded that although training improves spatial cognition in both sexes, the male advantage generally persists. However, because some studies run counter to this pattern, a closer examination of the anomaly is warranted. The authors investigated the acquisition of a basic skill (spatial selective attention) using a…

Aim: The aim of this study was to review the effects of early developmental intervention after discharge from hospital on motor and cognitive development in preterm infants. Method: Randomized controlled trials (RCTs) or quasi-RCTs of early developmental intervention programmes for preterm infants in which motor or cognitive outcomes were reported…

The decline in engineering degree enrolments in many western nations poses a range of challenges that are easy to identify but difficult to address. There have been at least 30 major reports on the issue of engineering enrolments in universities and a great many more on an allied issue, enrolments and achievement in science and maths areas at a…

This paper refers to a brief interaction with a mental health professional via written electronic communication. Web consulting services have proved popular, but there is controversy regarding the efficacy of such brief interventions to address problems and enable service users to access other forms of counseling. University students are…

The treatment outcome of a high-intensity inpatient sex offender treatment program was evaluated by comparing the sexual recidivism rates of 472 treated and 282 untreated sex offenders. The program is designed for moderate- to high-risk sex offenders and follows the principles of effective correctional treatment. The current investigation is an…

Clinical judgment is foundational to psychological practice. Accurate judgment forms the basis for establishing reasonable goals and selecting appropriate treatments, which in turn are essential in achieving positive therapeutic outcomes. Therefore, Spengler and colleagues' meta-analytic finding--clinical judgment accuracy improves marginally with…

Objective: To characterize the relationship between IQ and attention deficits in children with ADHD and to estimate the inattention-related mean influence on IQ when children are tested before stimulant drug treatment has been initiated. Method: Studies of various methodologies are reviewed. Results: Correlation studies show mostly weak…

One influential hypothesis for what makes teachers effective contends that the best teachers share a particular set of values about education, such as commitment, caring, or persistence. To translate affective beliefs, attitudes, and values into practicable teacher selection, many schools have turned to commercial teacher hiring instruments. This…

Health education researchers have called for research articles in health education to adhere to the recommendations of American Psychological Association and the American Medical Association regarding the reporting and use of effect sizes and confidence intervals (CIs). This article expands on the recommendations by (a) providing an overview of…

Delay discounting (DD), the tendency to prefer smaller, sooner rewards to larger, later ones, is an important indicator of self-control. Assessments of DD superficially require individuals to make choices based on motivational processes. However, several lines of evidence suggest that DD may be systematically related to cognitive ability. We…

This meta-analysis synthesized 102 effect sizes reflecting the relation between specific moods and creativity. Effect sizes overall revealed that positive moods produce more creativity than mood-neutral controls (r = 0.15), but no significant differences between negative moods and mood-neutral controls (r = -0.03) or between positive and negative…

In this meta-analytic study, the authors examined the efficacy of marriage and relationship education (MRE) on 2 common outcomes: relationship quality and communication skills. A thorough search produced 86 codable reports that yielded 117 studies and more than 500 effect sizes. The effect sizes for relationship quality for experimental studies…

Method: A meta-analysis was conducted of 33 observational studies comparing parent-child interactions in families where parents have a documented history of…

A meta-analysis of the stability of low IQ (IQ less than 80) was performed on IQ tests that have been commonly used--tests that were derived by D. Wechsler (1949, 1955, 1974, 1981, 1991, 1997) and those based on the Binet scales (L. M. Terman, 1960; L. M. Terman & Merrill, 1972). Weighted-mean stability coefficients of 0.77 and 0.78 were found…
