Individuals who are dually diagnosed with Down Syndrome (DS) and autism spectrum disorders (ASD) frequently engage in vocal stereotypy that can interfere with learning, impede socially appropriate behavior, and disrupt others. Response interruption and redirection (RIRD) is an intervention that blocks and redirects stereotypy to reduce behavior.…

The purpose of this mixed methods study was to determine if the RIRD intervention is effective in reducing vocal stereotypy in an individual with an autism spectrum disorder in the natural classroom setting with and without immediate reinforcement. The RRBs displayed by individuals with ASD may have a negative effect on the individual's ability to…

Considerable evidence has shown that physical exercise could be an effective treatment in reducing stereotypical autism spectrum disorder (ASD) behaviors in children. The present study seeks to examine the underlying mechanism by considering the theoretical operant nature of stereotypy. Children with ASD (n = 30) who exhibited hand-flapping and…

Children with autism spectrum disorder (ASD) display social-communication deficits and present with rigid and repetitive patterns of behavior and/or interests (RRBIs). Compared to interventions for social-communication skills, less attention has been given to RRBIs, especially with regard to interventions for young children. We surveyed 128…

This study uses geocoded address data and information about parents' economic behavior and children's development from four random-assignment welfare and anti-poverty experiments conducted during the 1990s. We find that the impacts of these welfare and anti-poverty programs on boys' and girls' developmental outcomes during the transition to early…

Critics of Head Start contend that many programs spend too much money on programs extraneous to children. On the other hand, Head Start advocates argue that the families of severely disadvantaged children need a broad range of services. Given the available evidence, it has been impossible to assess the validity of these claims. In this study, we…

This follow-up study examined effects (in grades two through five) of a two-year parent-child education program for low-income Mexican-American families of children ages one through three. There were no program effects on school grades, retention, or referrals, but program children achieved significantly higher on tests of reading, language, and…

The result of a collaboration between the El Paso, Texas, school district and community agencies, the Focus on First Graders program provides early intervention and prevention using a comprehensive approach to providing a variety of services at the school to at-risk first graders from low income families. Teachers and parents were surveyed to…
