Love, affection, acceptance, and companionship to children, these are just some of the benefits of a service dog for children. Yet there is much that these remarkable animals can do. From opening doors for children with cerebral palsy to warning a child with diabetes of low blood sugar, the abilities of a properly trained service dog are wide and…

We summarize a series of bidirectional research studies that demonstrate the persistence-strengthening effects of differential reinforcement of alternative behavior on problem behavior. We model a possible solution to this problem with rats followed by replication with a human clinical population. The importance of coordinated basic and applied…

There is a very substantial literature over the past 50 years on the advantages of early detection and intervention on the cognitive, communicative, and social-emotional development of infants and toddlers at risk for developmental delay due to premature birth or social disadvantage. Most of these studies excluded children with severe delays or…

Each year the members of the Interagency Autism Coordinating Committee identify recent research findings that made the most impact on the field. For the 2009 Summary of Advances, the IACC selected and summarized 20 studies that gave significant insight into the prevalence of autism spectrum disorder (ASD), the biology of the disorder, potential…

"Science Briefs" summarize the findings and implications of a recent study in basic science or clinical research. This Brief summarizes the findings and implications of "Exposure to Repetitive versus Varied Stress during Prenatal Development Generates Two Distinct Enxiogenic and Veuroendocrine Profiles in Adulthood" (H. N. Richardson; E. P.…

Peter B. Dews played a significant role in shaping the distinctive characteristics and defining the underlying principles of the discipline of behavioral pharmacology. His early and sophisticated use of schedules of reinforcement in the 1950s, incorporated from research in the experimental analysis of behavior and integrated into the discipline of…

A model of conditional discrimination performance (Davison & Nevin, 1999) is combined with the notion that unmeasured attending to the sample and comparison stimuli, in the steady state and during disruption, depends on reinforcement in the same way as predicted for overt free-operant responding by behavioral momentum theory (Nevin & Grace, 2000).…

Environmental restriction or deprivation early in development can induce social, cognitive, affective, and motor abnormalities similar to those associated with autism. Conversely, rearing animals in larger, more complex environments results in enhanced brain structure and function, including increased brain weight, dendritic branching,…
