The Repetitive Behavior Scale-Revised: Independent Validation in Individuals with Autism Spectrum Disorders
A key feature of autism is restricted repetitive behavior (RRB). Despite the significance of RRBs, little is known about their phenomenology, assessment, and treatment. The Repetitive Behavior Scale-Revised (RBS-R) is a recently-developed questionnaire that captures the breadth of RRB in autism. To validate the RBS-R in an independent sample, we conducted a survey within the […]
The Influence of Upcoming Food-Pellet Delivery on Subjects’ Responding for 1% Sucrose Reinforcement Delivered by Concurrent Random-Interval Schedules
Researchers have demonstrated that rats’ rates of operant responding that are maintained by 1% liquid-sucrose reinforcement will increase if food-pellet reinforcement is upcoming within the same session. The authors investigated whether a similar induction effect would be observed when rats pressed a lever for 1% sucrose that was delivered by concurrent random-interval schedules of reinforcement. […]
