In the No Child Left Behind Act and the What Works Clearinghouse, the federal government has attempted to establish guidelines for the type of education research that U.S. schools should consider in selecting instructional programs and resources. The government's clear preference for the medical model--a powerful research design in such fields as…

The notion of item context effects implies that psychometric properties of an item or scale are altered by the presentation format, for example, blocked versus randomized. In an experimental study with high school students, the experimental group (n = 407) answered a four-dimensional academic self-concept questionnaire, in which the items were…

A peer support intervention was developed to support aging caregivers and adults with developmental disabilities in planning for the future. The intervention consisted of a legal/financial training session followed by five additional small-group workshops. Pretest and 1-year follow-up surveys were conducted with 29 families participating in the…

This study sought to assess the effectiveness of a marital distress prevention program for couples by examining how marital quality, especially marital competencies such as dyadic coping, could be improved by means of a prevention program focusing on the enhancement of coping resources (Couples Coping Enhancement Training). The study consisted of…

This study evaluated the effectiveness of a new career development program designed to help adolescents explore their interest in enterprise as a career option. Using a person-oriented approach, pre- and post-test measurements of enterprising interests in an intervention (n=321) and a control group (n=302) of adolescents aged 16.5 years on average…

University students report significantly worse sleep quality than the general population. Sleep problems are related to increased health concerns, irritability, depression, fatigue, and attention and concentration difficulties, along with poor academic performance. Clinical research indicates that psychoeducational interventions are among the most…

The present work investigated the development of an explicit understanding of pretend play actions. Study 1 revealed a long decalage between earlier implicit understanding of pretence as an intentional activity and a later more explicit understanding. Study 2 was a training study. It tested for two factors--systematic pretence experience and…

Purpose: Preschoolers with language impairment have difficulties with both literal and inferential language, both of which are critical to later reading comprehension. Because these children are known to be at risk for later reading comprehension difficulties, it is important to design and test interventions that foster both literal and…

Background: Delay aversion, the motivation to escape or avoid delay, results in preference for small immediate over large delayed rewards. Delay aversion has been proposed as one distinctive psychological process that may underlie the behavioural symptoms and cognitive deficits of attention deficit/hyperactivity disorder (ADHD). Furthermore, the…

Background: Children with pervasive developmental disorder (PDD) show behavioral abnormalities in gaze and face processing, but recent studies have indicated that normal activation of face-specific brain areas in response to faces is possible in this group. It is not clear whether the brain activity related to gaze processing is also normal in…

Background: The goal of this study was to evaluate the interactions of mothers with normative or high levels of depressive symptomatology on the Center for Epidemiologic Studies-Depression Scale (CES-D) and their 3-month-old infants. Although successful mutual regulation of affect is critical to children's socio-emotional development, little is…

Background: WILSTAAR comprises a programme for identifying and treating 8-10-month-old infants who are at risk of language and cognitive difficulties. It has been adopted by health trusts, and included in Sure Start intervention schemes, throughout the UK. This study addresses one of the main queries raised by critics of the programme, by…

Background: Despite findings that parent depression increases children's risk for internalizing and externalizing problems, little is known about other factors that combine with parent depression to contribute to behavior problems. Methods: As part of a longitudinal, interdisciplinary study on childhood-onset depression (COD), we examined the…

How verbal information is processed and recalled appears to be influenced by the structure of the information presented (e.g., unrelated sentences vs. narratives) and the processes the listener uses to encode the information (e.g., verbatim encoding vs. gist extraction). Twenty adults, half with a history of learning disabilities (HLD) and half…

Several evaluations of private school voucher programs in the United States have reported achievement gains for voucher users, particularly African Americans. These studies tend to be structured as Randomized Field Trials (RFTs) in which participants are assigned to treatment (offered a voucher) and control (not offered a voucher) groups by…
