Electronic books (e-books) are a prevalent method for integrating technology in preschool and elementary classrooms; however, there is a lack of consensus concerning the extent to which e-books increase literacy skills in the domains of comprehension and decoding. This article assesses the efficacy of e-books with a comprehensive review method,…

Objective: To examine the results of prison privatization. Method: In an effort to provide an empirical base from which decisions about privatization might be made, we conducted a meta-analysis of reports on head-to-head comparisons between an identifiable privately managed and publicly managed prison(s). Results: Our search identified 12 studies.…

Theoretical models of addiction suggest that attentional bias for substance-related cues should be associated with self-reported craving. The authors evaluated the strength of the association by performing a meta-analysis on 68 independent data sets from which correlation coefficients between subjective craving and attentional bias indices were…

The efficacy of cognitive-behavioral therapy (CBT) for anxiety in adults is well established. In the present study, the authors examined whether CBT tested under well-controlled conditions generalizes to less-controlled, real-world circumstances. Fifty-six effectiveness studies of CBT for adult anxiety disorders were located and synthesized.…

While much has been written about the implications for "literacy" of practices surrounding digital technologies, there has been surprisingly little research investigating new literacies in primary classrooms. This review examines the kinds of understandings that have been generated through studies of primary literacy and technology…

Background: This meta-analysis of interventions with challenging behaviour in children with disabilities updates a comprehensive meta-analysis that previously addressed reported standards of practice and effectiveness of different strategies. Method: Four effect-size algorithms were calculated for published intervention cases, and results analysed…

Objective: This article is a review of outcome studies focusing on three social work fields of service--health, substance abuse, and mental health--in which Latinos were significantly represented in the sample and interventions developed to attend to cultural factors. Method: Data were collected from a search of several English language social…

This is Part 2 of a three-part summary of selected articles from the journals of the American Association of School Librarians (AASL) over a period of thirty-five years from 1972 to 2007. This three-part series in the April, May, and June (2009) issues of "School Library Media Activities Monthly" ("SLMAM") will illustrate the evolution in…

A meta-analysis was undertaken, including 41 studies to determine the influence of Catholic and Protestant schools. The analysis examined studies undertaken at both the elementary and secondary school level. The results indicate that both Catholic and Protestant school students do better than their counterparts in public schools. In addition,…

Evidence indicates that experience-dependent cortical plasticity underlies post-stroke motor recovery of the impaired upper extremity. Motor skill learning in neurologically intact individuals is thought to involve the primary motor cortex, and the majority of studies in the animal literature have studied changes in the primary sensorimotor cortex…

A meta-analysis of 41 studies examined the effect of choice on intrinsic motivation and related outcomes in a variety of settings with both child and adult samples. Results indicated that providing choice enhanced intrinsic motivation, effort, task performance, and perceived competence, among other outcomes. Moderator tests revealed the effect…

Do differences in individualism and collectivism influence values, self-concept content, relational assumptions, and cognitive style? On the one hand, the cross-national literature provides an impressively consistent picture of the predicted systematic differences; on the other hand, the nature of the evidence is inconclusive. Cross-national…

Theory of mind is claimed to develop universally among humans across cultures with vastly different folk psychologies. However, in the attempt to test and confirm a claim of universality, individual studies have been limited by small sample sizes, sample specificities, and an overwhelming focus on Anglo-European children. The current meta-analysis…

In this comment on C. F. Bond and B. M. DePaulo, the authors raise methodological concerns about the approach used to analyze the data. The authors suggest further refinement of the procedures used, and they compare the approach taken by Bond and DePaulo with standard methods for meta-analysis. (Contains 1 table and 2 figures.)

An integrative social identity model of collective action (SIMCA) is developed that incorporates 3 socio-psychological perspectives on collective action. Three meta-analyses synthesized a total of 182 effects of perceived injustice, efficacy, and identity on collective action (corresponding to these socio-psychological perspectives). Results…
