-
Blocking of stimulus control and the conditioning of new reinforcers
How can social consequences be established as conditioned reinforcers in children with autism, and what can challenge the establishing?
-
Subjective discounting of delayed rewards
The project examines preference for immediate versus delayed rewards in animal models and in humans to identify variables that control choice.
Completed research projects
-
Effects of reinforcement on behavioral variability
The effect of reinforcement and extinction on behavioral variability and the effects reinforcement and punishment have on rule-governed insensitivity.
-
Pro-social behavior in rats
We studied pro-social and empathetic behavior in rats by having one rat restrained in a plastic tube and a cagemate that could release the rat.
