Effects of alternative reinforcement sources: A reevaluation

Effects of alternative reinforcement sources: A reevaluation.

The effects of two alternative sources of food delivery on the key-peck responding of pigeons were examined. Pecking was maintained by a variable-interval 3-min schedule. In the presence of this schedule in different conditions, either a variable-time 3-min schedule delivering food independently of responding or an equivalent schedule that required a minimum 2-s pause between a key peck and foo...

Effects of alternative responses on behavior exposed to noncontingent reinforcement.

Noncontingent reinforcement (NCR) may decrease the frequency of behavior by either inducing satiation or terminating the response-reinforcer contingency (extinction). Another possibility is that the target behavior is replaced by other behaviors maintained by preexisting contingencies. We conducted 2 experiments in which we allowed access to a target response and several alternatives. In Experi...

Running Head: DIFFERENTIAL REINFORCEMENT OF ALTERNATIVE BEHAVIOR An Investigation of the Effects of Differential Reinforcement of Alternative Behavior On Students with Mild/Moderate Disabilities In a School Classroom

Effects of treatment integrity failures during differential reinforcement of alternative behavior: a translational model.

Differential reinforcement of alternative behavior (DRA) is used frequently as a treatment for problem behavior. Previous studies on treatment integrity failures during DRA suggest that the intervention is robust, but research has not yet investigated the effects of different types of integrity failures. We examined the effects of two types of integrity failures on DRA, starting with a human op...
