Investigates (1) the relationships between cognitive performance and cognitive styles and predictive possibilities and (2) performance differences by sex, school, grade, and income in 92 Indian adolescents. Assessment measures included Liquid Conservation, Islands, Goat-Lion, Hanoi-Tower, Rabbits (Piagetian); Block Design (WISC-R); Paper Cutting…

Examined development of concern and externalizing problems in children at three behavior problem levels. Found no group differences in concern at 4-5 years. Concern in children with clinical behavior problems decreased by 6-7 years. Greater concern at 4-5 or at 6-7 years predicted decreased stability and severity of externalizing problems by 6-7…

Examined extent to which demographics, students' personal resources, and family resources predicted stable or lowered educational expectations from eighth grade to 2 years post-high school. Found that predictors of lost talent or lowered expectations over time included low SES and racial group membership. External locus of control predicted lost…

Although maladaptive and compulsive behaviors are increasingly well-described in young persons with Prader-Willi syndrome, it is unclear how these problems manifest in older adults with this syndrome. In Part I, I compared maladaptive and compulsive behaviors in 45 older adults with Prader-Willi syndrome (ages 30 to 50 years) to 195 children,…

Heterogeneity of variance may be more than a statistical nuisance--it may be of direct interest as a result of individual differences. In studies of short-term fluctuation, individual differences may relate to the magnitude of within-person variation as well as to level of an outcome or its covariation with other processes. Although models for…

Schools and school systems throughout the nation are increasingly experimenting with using various instructional technologies to improve productivity and decrease costs, but evidence on both the effectiveness and the costs of education technology is limited. A recent report published by the Thomas B. Fordham Institute sets out to describe "the…

The purpose of this study was to investigate teacher practices of enabling factors in the implementation of technology-assisted PBL, in Tatweer schools in Jeddah, Saudi Arabia. This study also explored how the International Society for Technology in Education (ISTE) National Education Technology Standards for Teachers (NETS.T) were used in Tatweer…

At most colleges and universities, African American and Latino students are less likely than students from other racial and ethnic backgrounds to stay enrolled in college and are, therefore, less likely to earn a college degree. "The Digest of Educational Statistics" reports the following trends: in 2006 30% of Whites age 25 and older…

Nearly one-quarter of students in community colleges leave school during the first year of enrollment for reasons other than transfer or credential completion. Generally, nontraditional community college students drop out within their first year at higher rates than do traditional students. Using data from Achieving the Dream: Community Colleges…

This study considered whether sensitivity to speech rhythm can predict concurrent variance in reading attainment after individual differences in age, vocabulary, and phonological awareness have been controlled. Five- to six-year-old English-speaking children completed a battery of phonological processing assessments and reading assessments, along…

The current study was designed to investigate children's memory and suggestibility for events differing in valence (positive or negative) and veracity (true or false). A total of 82 3- and 5-year-olds were asked repeated questions about true and false events, either in a grouped order (i.e., all questions about a certain event asked consecutively)…

This study was a 3-year follow-up of 65 male and 138 female same-sex couples who had civil unions in Vermont during the 1st year of that legislation. These couples were compared with 23 male and 61 female same-sex couples in their friendship circles who did not have civil unions and with 55 heterosexual married couples (1 member of each was a…

Declines in support for the male breadwinner, female homemaker family model in recent decades have been thoroughly documented, but research into the way such attitudes change over the life course remains limited. Drawing on panel data and latent growth curve modeling techniques, the study identifies patterns and predictors of attitude change from…

This study investigated predictors of grandparent satisfaction. Participants were 149 non-custodial grandparents (100 grandmothers, 49 grandfathers) aged up to 80 years. They completed grandparent satisfaction, meaning, and generativity scales, and indicated levels of weekly childcare contact with grandchildren. As expected, increasing levels of…

Alcohol studies, like most psychological studies, have traditionally focused on males. Several psychosocial theories have been used to explain male alcoholism, including dependency, the power drive, and sex role theory. This latter stance may provide a theoretical framework for the etiology of drinking which will apply to both sexes; however,…
