Discrete-trial training performance of behavior interventionists with autism spectrum disorder: A systematic replication and extension.

Further research is needed on strategies to improve employment outcomes for individuals with autism spectrum disorder (ASD). We replicated and extended prior research by examining the acquisition, maintenance, and generalization of discrete-trial training (DTT) performance of adults with ASD who were interested in careers as behavior technicians. Three participants received training on how to implement DTT with children and we assessed the maintenance and generalization of DTT performance in the absence of feedback.

Teaching social play skills to adults and children with autism as an approach to building rapport.

Adults with autism spectrum disorder (ASD) and no intellectual disabilities were taught to increase the social play skills of children with ASD as part of a vocational training program. Participants included 3 adults, aged 21 to 27 years, and 6 children with ASD. Probes conducted throughout the study evaluated whether play skills training affected a measure of rapport between the adult and child.

Adults with autism spectrum disorder as behavior technicians for young children with autism: Outcomes of a behavioral skills training program.

Adults with autism spectrum disorder (ASD), who were interested in working as behavior technicians for young children with autism, participated in 2 experiments. Participants included 5 adults with Asperger syndrome or pervasive developmental disorder not otherwise specified, 19 to 23 years old, and 11 children with autism, 3 to 7 years old. In Experiment 1, training of the adults focused on the implementation of mand training via incidental teaching.

Naloxone and rimonabant reduce the reinforcing properties of exercise in rats.

Naloxone and rimonabant block neurotransmitter action of some drugs of abuse (such as ethanol, opiates, and nicotine), and thereby reduce drug seeking and self-administration by suppressing the drugs' reinforcing properties. The present study represents an attempt to elucidate whether these drugs may also reduce rewarding properties of other events, in this case, activity-based reinforcement. In Experiment 1, 10 obese and 10 lean Zucker rats pressed a locked door under a progressive ratio schedule of reinforcement that, when unlocked, provided access to a running wheel for 2-min intervals.

Demand for sucrose in the genetically obese Zucker (fa/fa) rat.

Obese Zucker rats (fa/fa) eat more food than lean controls in free-feeding conditions, which strongly influences their phenotypic expression. Few studies, however, characterize their food consumption in environments that are more representative of foraging conditions, e.g.
