The Effects of Extinction on Human Performance Following Exposure to Fixed Ratio Schedules of Reinforcement

Description: This experiment examined the effects of extinction on rate of responding and several topographical and temporal measures in adult humans. Three college students were trained to type the sequence 1•5•3 on a numeric keypad on a computer. The subjects were exposed to different fixed-ratio schedules of reinforcement (FR1, FR 5, and FR10 respectively) and extinction. Subjects displayed typical schedule performances during the maintenance phase of the experiment. During extinction the performances we… more

Training Siblings of Children with Autism to Instruct Play: Acquisition, Generalization, and Indirect Effects

Description: A multiple baseline design was employed to evaluate the effectiveness of a sibling training package including modeling, role-play, and feedback on play and engagement between children with autism and their siblings. The results of two experiments suggest that, following training, siblings of children with autism correctly implemented all trained interaction components. Additionally, Experiment II assessed and programmed generalization to other materials and a non-training setting. The results s… more
