The persistence of sleep problems in preschool children is examined against the matched comparison groups of children with developmental delay without autism and typically developing children. Objective and subjective measures of sleep problems of preschool-aged children were found to have produced varying results.

This study examines whether feeding infants formula supplemented with long-chain polyunsaturated fatty acids (LCPUFA) improves cognitive function of 9-month-olds. Participants included 229 infants from 3 randomized controlled trials. Children received either formula supplemented with docosahexaenoic acid and arachidonic acid, or a control formula…

Making connections between various representations is important in mathematics. In this article, the authors discuss the numeric, algebraic, and graphical representations of sums of absolute values of linear functions. The initial explanations are accessible to all students who have experience graphing and who understand that absolute value simply…

Guided by a family stress perspective, we examined the hypothesis that discussing money would be associated with the handling of marital conflict in the home. Analyses were based on dyadic hierarchical linear modeling of 100 husbands' and 100 wives' diary reports of 748 conflict instances. Contrary to findings from previous laboratory-based…

After years of growth and predictions that fund raising for higher education would escape the brunt of the economic crash, the recession has started to affect colleges' efforts to raise money, according to a survey by "The Chronicle" and Moody's Investors Service. Predictions are that 2009 may be an even tougher year for fund raisers, with…

Nationally, 15% of children younger than 5 years regularly attend more than 1 child-care arrangement. An association between arrangement multiplicity and children's behavior problems has been identified, but previous research may be susceptible to measurement or omitted variable bias. This study used within-child fixed effects models to examine…

In this volume, Furberg and Arnseth report on a study of genetics learning from a socio-cultural perspective, focusing on students' meaning making as they engage in collaborative problem solving. Throughout the paper, they criticize research on student understanding and conceptual change conducted from a cognitive/socio-cognitive perspective on…

This study provides evidence for intrinsic and extrinsic motivators for stereotypical and repetitive behavior in children with autism and intellectual disability and children with intellectual disability alone. We modified the Motivation Assessment Scale (MAS) (1988b); dividing it into intrinsic and extrinsic measures and adding items to assess…

Children's failure on equivalence problems (e.g., 5 + 4 = 7 + __) is believed to be the result of misunderstanding the equal sign and has been tested using symbolic problems (including "="). For Study 1 (N = 48), we designed a nonsymbolic method for presenting equivalence problems to determine whether Grade 2 children's difficulty is due…

Mandated teacher evaluations are of little use to educators for a variety of reasons, including lack of reliability and validity of evaluation instruments and methods, failure of evaluation systems to adhere to the Personnel Evaluation Standards (Joint Committee, 2008), and the inherent bias in using classroom observations as a method of…

This article reports that young inventors at a Maryland high school are not only learning scientific principles, but also teamwork and the tenets of patent law. Twice a week, 10 members of the Clarksburg High School's Coyote Inventors Club gather in a second-floor computer lab to peck away at building a deceptively simple device: a cable that…

School psychologists are interested in providing effective and efficient direct services to children. With a wide spectrum of psychological problems impacting children, group counseling represents one viable and valuable intervention. Given the complexity of group counseling, many schools and school psychologists are interested in legal and…

Choice between alternative response options has received much attention in both basic and applied research. However, there is limited study on the effects of choice of task order on responding. This study examined the effect of choice of task order on on-task behavior, duration to complete the tasks, and problem behaviors in 2 children with autism…

In recent years clinicians report a great deal of concern about definition, diagnostic assessment, and treatment modalities when dealing with what might be called out-of-control sexual behavior. Many terms have been used to describe the phenomenon of problematic sexual behavior. Many of these concepts overlap, some are no longer popular, and some…

A 3-week problem-solving practice phase was used to investigate concept-procedure interactions in children's addition and subtraction. A total of 72 7- and 8-year-olds completed a pretest and posttest in which their accuracy and procedures on randomly ordered problems were recorded along with their reports of using concept-based relations in…
