We review comparative studies of infant habituation and dishabituation performance focusing on preterm infants. Habituation refers to cognitive encoding, and dishabituation refers to discrimination and memory. If habituation and dishabituation constitute basic information-processing skills, and preterm infants suffer cognitive disadvantages, then…

The bulk of personality research has been built from self-report measures of personality. However, collecting personality ratings from other-raters, such as family, friends, and even strangers, is a dramatically underutilized method that allows better explanation and prediction of personality's role in many domains of psychology. Drawing…

The present meta-analysis integrates results of 21 controlled couple-focused interventions with expectant and new parents. The interventions had, on average, small effects on couple communication (d = 0.28 standard deviation units) and psychological well-being (d = 0.21), as well as very small effects on couple adjustment (d = 0.09). Stronger…

A recent large-scale meta-analysis of twin and adoption studies indicated that shared environmental influences make important contributions to most forms of child and adolescent psychopathology (Burt, 2009b). The sole exception to this robust pattern of results was observed for attention-deficit/hyperactivity disorder (ADHD), which appeared to be…

Burt (2009) recently published a meta-analysis of twin studies on behaviors associated with childhood psychopathologies, concluding that the finding that traits associated with attention-deficit/hyperactivity disorder (ADHD) were the only behaviors that did not show a significant influence of shared environment (C) was surprising. We agree,…

Social cognitive career theory (SCCT; Lent, Brown, & Hackett, 1994) seeks to explain the factors that shape educational and vocational interests and choices. We used meta-analytic path analyses to synthesize data (from 1981 to 2008) relevant to SCCT's interest and choice hypotheses, organizing the literature according to Holland's (1997) broad…

Most of the statistical procedures in meta-analysis are based on the estimation of average effect sizes from a set of primary studies. The optimal weight for averaging a set of independent effect sizes is the inverse variance of each effect size, but in practice these weights have to be estimated, being affected by sampling error. When assuming a…

In this meta-analysis study, a total of thirty-one studies related to strategy use of students in Taiwan in a web-based English context were identified, collected, and analysed. Three criteria for selecting the appropriate studies are (a) they must have applied web-based instruction; (b) they must be related to English learning; and (c) they had…

The purpose of this study is to examine the effects of morphological instruction on language and literacy outcomes by synthesizing 92 standardized mean differences (d) from 30 independent studies. Findings show a moderate overall effect of morphological instruction ([d-bar] = 0.32), suggesting that children receiving morphological instruction…

Background: Educational and skills-based interventions are often used to prevent relationship and dating violence among young people. Objectives: To assess the efficacy of educational and skills-based interventions designed to prevent relationship and dating violence in adolescents and young adults. Search Methods: We searched the Cochrane Central…

This meta-analysis summarizes research on the effects of a comprehensive, interactive web-based software (AXXX) on the development of reading competencies among kindergarteners and elementary students. Findings from seven randomized control trials and quasi-experimental studies undertaken in a variety of contexts across Canada, Australia and Kenya…

Positive attitudes held by general classroom teachers toward the principles of inclusion and toward students with disabilities are central in ensuring the successful progress of the inclusive movement. To underline the critical nature of teacher attitudes, this comparative study draws on a sample of the literature from western nations implementing…

The focus and purpose of this research is to examine the benefits, limitations, and implications of Individual Participant Data (IPD) meta-analysis in education. Comprehensive research reviews in education have been limited to the use of aggregated data (AD) meta- analysis, techniques based on quantitatively combining information from studies on…

Information and communication technologies (ICT) have an essential role in today's organizations and ever-changing dynamic environments. ICT has substantial tangible and intangible impact on organizations not only in usual environments, but also in extreme environments. This dissertation is composed of three essays on the impact of ICT in…

"Professional Development Schools: Researching Lessons from the Field" provides a comprehensive analysis of PDS research that can aid PDS stakeholders in designing and sustaining meaningful research in their partnerships. Breault and Breault used an extensive qualitative meta-synthesis to examine the research over the past 20 years. Their…
