Background: There is a need to systematically compare and contrast mortality predictors and disparities in people with intellectual disabilities (ID) for global prevention strategy development. Method: Bibliographic databases and grey literature were searched using systematic review methodology and the machine learning tool "Abstrackr."…

Teachers are increasingly using social networks, including social media and other Internet applications, to look for educational resources. This study shares results from a survey examining patterns of social network application use among K-12 teachers in the United States. A sample of 154 teachers (18 males, 136 females) in the United States…

This meta-analysis used hierarchical linear modeling to examine 115 single-case studies with 343 participants that examined the effectiveness of social skills interventions for individuals with autism spectrum disorder (ASD). The average effect size of the included studies was 1.40 (SD = 0.43, 95% CL = 1.32-1.48, N = 115). In the further, several…

In this article, the authors clarify and provide additional tests of the key elements of their age-period-cohort analysis of non-marital birth rates in this March 2009 issue of "Social Forces." Where Steve Martin, in his commentary, has suggested specific alternative specifications or interpretations of their findings, the authors have…

Analogous thinking has been commonly discussed as being an inherent and distinguishing characteristic of human cognition (e.g., Gentner, 2010; Goldstone, Day, & Son, 2010; Holyoak, in press; Rittle-Johnson & Star, in press). Gentner (2003) has argued that as part of the human cognitive toolbox, comparison accompanied by the relational language to…

The longitudinal relationships between depression, anxiety, conduct problems, and inattention were investigated. The present study attempted to overcome the methodological limitations of prior research on childhood co-occurring syndromes by using continuous measures of constructs, controlling for multiple symptoms at baseline, and considering the…

An important but too infrequently considered methodology that can be used in research, especially research focusing on Pearson's "r" (B. Walsh, 1996) or the multiple "R" (see B. Thompson, 1992) involves testing for moderator or mediator variable effects. As explained by M. Gall, W. Borg, and J. Gall (1996), moderator analysis…

This paper provides a brief overview of what is currently known about families of children with Down syndrome. In addition, it highlights a number of issues that require further research if we are to have a thorough understanding of the impact of a child with Down syndrome on families as a system and on the individuals who make up that system.…

Recent research in linguistic theory and language acquisition theory has progressed to the point where more detailed hypotheses can be made about the interaction of language learning and linguistic theory. These hypotheses can be used to make more precise predictions about prerequisite knowledge for learning a particular construction and the…

Findings in a study of 94 children in nursery school and day care who completed landmark placement, mental rotation, and map tasks suggested the existence of 2 different, age-related strategies of map use. Younger and older map users may make different tradeoffs between encoding and updating. (RH)

To investigate the causes of variation in cloze-comprehension test correlations, a reanalysis was conducted of the influential J.R. Bormuth study (1962), which reported correlations between nine cloze and nine comprehension tests administered to 50 subjects in grades 4, 5, and 6. Two separate renalayses were completed in the present study, the…

The evidence for possible negative effects of first-name characteristics on personal functioning is equivocal. Two studies were conducted that avoided previous methodological problems of measurement, sampling, and statistical control. Results indicated that children's social competence and school achievement were unrelated to the frequency or…

Illustrates the use of a Piagetian-influenced research strategy in overcoming existing methodological problems in human experience research and presents illustrative data on human early experience research which has so far yielded inconsistent data. (GO)

Data from the National Science Foundation Fellowship applicant records and the NRC Office of Scientific Personnel Doctorate Records File were utilized to evaluate the potential of GRE Aptitude and Advanced Tests as predictors of whether or not the candidate attained the doctorate within a period of from seven to ten years. In addition, the study…
