Autism spectrum disorders (ASD) are associated with cognitive dysfunctions, including mental time travel (MTT). However, findings on diminished MTT ability may be confounded by a number of factors, including the individuals' language ability, factors related to the MTT task and the demographic factors of participants. The present study provided a…

School start times for adolescents in the United States are typically too early to be healthy for this age group. There is significant evidence from the research literature that early starts have serious negative impacts on students. In particular, early education start times in adolescence cause chronic sleep deprivation, which damages both…

To date, researchers have frequently investigated students' attitudes toward courses supported by problem-based learning. There are several studies with different results in the literature. It is necessary to combine and interpret the findings of these studies through a meta-analysis method. This method aims to combine different results of similar…

Communication partners who efficiently use augmentative and alternative communication (AAC) are essential interaction partners for children learning to communicate using AAC. This systematic review examines studies targeting interventions designed to help communication partners support children with complex communication needs who use AAC.…

This research synthesis examines whether the association between print exposure and components of reading grows stronger across development. We meta-analyzed 99 studies (N = 7,669) that focused on leisure time reading of (a) preschoolers and kindergartners, (b) children attending Grades 1-12, and (c) college and university students. For all…

In this study, we meta-analyzed empirical research of the effectiveness of intelligent tutoring systems (ITS) on K-12 students' mathematical learning. A total of 26 reports containing 34 independent samples met study inclusion criteria. The reports appeared between 1997 and 2010. The majority of included studies compared the effectiveness of ITS…

The purpose of the present study is to provide a historical account and metasynthesis of which statistical techniques are most frequently used in the fields of education and psychology. Six articles reviewing the "American Educational Research Journal" from 1969 to 1997 and five articles reviewing the psychological literature from 1948 to 2001…

The authors reviewed article and author patterns for articles published in the "Journal of Employment Counseling (JEC)" from 1994 through 2009. Author demographic characteristics assessed included sex of lead and all authors, lead author domicile, employment setting of lead and all authors, and individuals and universities contributing most…

A meta-analytic review of empirical studies that have investigated incubation effects on problem solving is reported. Although some researchers have reported increased solution rates after an incubation period (i.e., a period of time in which a problem is set aside prior to further attempts to solve), others have failed to find effects. The…

This author became intrigued by the idea that her generation, who had grown up reaping the benefits of second-wave feminism, might differ from previous generations in their attitudes toward women. What was unclear was how this period of progress might have combined with feminist backlash in affecting subsequent generations' responses to typical…

Describes analyses based on 35 studies on effectiveness of Grief Therapy. Clients with no-treatment control groups showed little improvement, possibly because of the relatively long delay between loss and treatment. Client selection procedures appear to contribute strongly to variability in effect size (ESs). The majority of studies involving…
