A synthesis of results from 35 studies of the association between academic and occupational performance in various fields indicated that academic indicators such as grades and test scores account for only 2.4 percent of the variance in occupational performance criteria such as income, job satisfaction, and effectiveness ratings.

The fundamental question to which most clients want and deserve an answer is, "Am I going to get better (as a result of counseling)?" Although meta-analyses provide strong evidence supporting the efficacy of counseling in general, if one wants to make probabilistic statements about individual client outcomes--rather than about the more generalized…

The double-deficit hypothesis of developmental dyslexia proposes that deficits in phonological processing and naming speed represent independent sources of dysfunction in dyslexia. The present article is a review of the evidence for the double-deficit hypothesis, including a discussion of recent findings related to the hypothesis. Studies in this…

Whether or not there are sex differences in helping behavior is a question that has attracted interest from both theoretical and applied perspectives. A meta-analysis was conducted of 172 studies of helping behavior, coded for publication date, source, sex of author, sample size, setting, type of appeal for help, availability of other helpers, sex…

Discusses results of a meta-analysis which sought to identify those variables found in research as strongly correlated with responsible environmental behavior. Variables found significant were: knowledge of issues; knowledge of action strategies; locus of control; attitudes; verbal commitment; and sense of responsibility. Proposes a model of…

Research syntheses of individual bivariate studies of the effects of specific predictor variables on student outcomes are considered. Walberg's nine-factor model of educational productivity is used to organize the syntheses and to identify aptitudinal, instructional, and environmental variables linked with student achievement and learning.

Examined extent to which infant-mother attachment could be predicted by mother interactional variables and infant proneness to distress. Meta-analysis indicated that sensitive, responsive maternal interaction predicted the security of attachment in Ainsworth and Wittig's "strange situation." Proneness to distress, a temperamental variable,…

Presents the results of a meta-analysis of the predictors of female delinquency. Finds that most of the strong predictors of female delinquency are the same as those for males, including history of antisocial behavior, antisocial attitudes, antisocial peers, and antisocial personality. School and family relationships and a history of…

This article reports findings from a "meta-review" and synthesis of research on variables related to learning, including both cognitive and affective schooling outcomes. Results confirm that distal policy variables are less important to schooling outcomes than quantity and quality of instruction, home environment, or student characteristics. (IAH)

Meta-analysis of the A-not-B error was conducted, using logistic regression, on studies conducted before September 1997. Results replicated earlier findings, with exception that the number of trials at the A location was a significant predictor, and the number of locations was a significant predictor of the proportion of infants who searched…

Conducted meta-analysis of preschool and early elementary school self-esteem instruments, using reliability as criterion variable and different aspects of methodology used in testing an instrument as predictor variables. Found that reliability could be predicted by study setting, number of items in the scale, age of children being studied, method…

A meta-analysis was conducted on all studies of suicide mortality in follow-up studies of schizophrenic patients that presented data for male and female patients separately. The percentage of deaths from suicide was significantly greater for the male schizophrenic patients than for the female schizophrenic patients in studies where both sexes were…

A meta-analysis was conducted to investigate whether specific reading disorder (SRD) groups demonstrate a deficit in using phonological recoding strategies. Thirty-four studies were reviewed that had compared the nonword reading performances of SRD groups with reading-level matched (RL) control groups. The average nonword reading difference…

Published literature pertaining to the simultaneous prompting teaching procedure is reviewed. Purposes of this review are to (a) present an initial analysis of effectiveness of this emerging response prompting procedure, (b) discuss work that has been conducted to date, and (c) provide directions for future research. Data from all published…

This paper presents cross-section estimates of gross hourly wage premia on tertiary education. They are based on a unified framework for 21 OECD countries from the 1990s to the early 2000s and use international household surveys to maximise international comparability. The results of the "augmented" Mincerian wage equations point to an…
