Despite its advantages, discrete-trial instruction (DTI) has been criticized for producing rote responding. Although there is little research supporting this claim, if true, this may be problematic given the propensity of children with autism to engage in restricted and repetitive behavior. One feature that is common in DTI that may contribute to…

Although social-communication difficulties and repetitive behaviors are hallmark features of autism spectrum disorder (ASD) and persist across the lifespan, very few studies have compared age-related differences in these behaviors between youth with ASD and same-age typically developing (TD) peers. We examined this issue using SRS-2 (Social…

Kindergarten retention is a popular practice for children who are considered unready for primary school. However, past research has not yet succeeded to find consistent, strong empirical evidence supporting the practice. In the current study, kindergarten repeaters' development in nine psychosocial domains is compared with that of equally at risk…

Background: The prevalence of autism spectrum disorder (ASD) symptomatology is comparatively high in Cornelia de Lange syndrome (CdLS). However, the profile and developmental trajectories of these ASD characteristics are potentially different to those observed in individuals with idiopathic ASD. In this study we examine the ASD profile in CdLS in…

This longitudinal study investigates whether rural adolescents who transition to a new school in sixth grade have higher levels of risky behavior than adolescents who transition in seventh grade. Our findings indicate that later school transitions had little effect on problem behavior between sixth and ninth grades. Cross-sectional analyses found…

Mounting evidence suggests that being an old-for-grade student, as a result of grade retention or delayed school entry, is related to negative outcomes across various domains of functioning. No known study has examined the relations between old-for-grade status and specific childhood/adolescent bully and victim behaviors. The first purpose of this…

The authors investigated the relatively short-term and longer term effects of grade retention in 1st grade on the growth of mathematics and reading achievement over 4 years. The authors initially identified a large multiethnic sample (n = 784) of children who were below the median in literacy at school entrance. From this sample, the authors…

This study examines the effects of kindergarten retention on children's social-emotional development in the early, middle, and late elementary years. Previous studies have generated mixed results partly due to some major methodological challenges, including selection bias, measurement error, and divergent perceptions of multiple respondents in…

The authors examined the developmental pathways between high school graduates and dropouts. The authors obtained official school data via a random sample of 119 students enrolled across 4 cohorts. The authors postulated 2 research questions: (a) Do differences exist in the developmental pathways of high school graduates in comparison with high…

This study examines the demographic, academic, social, and behavioral differences between GED (General Educational Development) Tests candidates who were and were not retained in grade. Differences between candidates who were and were not retained in grade are examined with regard to factors such as demographics, delinquent behaviors, reasons for…

We evaluated contingent and noncontingent practice of an alternative behavior (appropriate play) as intervention for stereotypy that occurred with two play objects in a 5-year old boy with autism. Contingent practice was implemented as a consequence for stereotypy, and the rate of noncontingent practice was matched (yoked) to that schedule. On…

Compared children retained in kindergarten with matched samples of age and grade mates, using teacher ratings as an index of their social and academic skills. Found that retained children showed a reduction in behavior problems, specifically acting-out and shy-anxious behaviors, but only slightly increased competence for task orientation across…

As follow-up to an in-depth study of the District of Columbia's early learning programs and their impact, this study provided data on the transition of previously studied children from primary education to upper elementary grades. Academic progress of the original group of pre-kindergarten and Head Start children was studied during years 5 and 6…

This study investigated outcome data obtained from six samples of primary school students, four of which consisted of at-risk students. Participants were: (1) 46 students from a transitional first-grade, developmental, regular education school readiness program (SRP) for at-risk kindergartners; (2) 20 nonplaced kindergartners who were recommended…

Examined effects of time-limited welfare on children ages 5- to 17-years at a 4-year follow-up. Found that effects were moderated by families' risk of long-term welfare dependency. Found few effects for children of parents most likely to reach the welfare time limit. Found consistent negative effects for children of parents with the largest…
