observation period Discriminative stimulus o A stimulus in the presence of which responses of some type have been reinforced and in the absence of which the same type of responses have occurred and not been reinforced; this history of differential reinforcement is the reason sD increases the momentary frequency of the behavior Maintaining contingencies o Behavior contracts o A mutually agreed upon document between parties that specifies a contingent relationship between the completion of specified behaviors and access to specified reinforcers Operational definition for behavior pg. 32 o an important part of prioritizing a target for intervention. A precise description of the behavior of concern. Meets 3 important criteria: 1. Be objective. Should include only observable and measurable characteristics of behavior.
