This cluster shows how a child's behavior can suddenly change when the rules of the game switch. If a child gets lots of praise in one room but none in the next, they may work harder or give up, depending on what is coming. BCBAs use these findings to set up smooth transitions between tasks and keep motivation steady. Knowing how contrast works helps prevent unwanted drops or jumps in behavior during therapy.
Common questions from BCBAs and RBTs
It is a change in response rate in one part of a session caused by a change in reinforcement in a different part. If reinforcement drops in one activity, behavior in the next activity can unexpectedly increase or decrease.
Keep each schedule component long enough before switching activities, use clear signals that tell the client what to expect next, and avoid rapid transitions between richly and thinly reinforced tasks.
Yes. What looks like a skill breakthrough may actually be positive contrast from a lean schedule that just ended. Review your schedule design before assuming the improvement reflects genuine skill acquisition.
Research shows that colored card signals that predict reinforcement availability can cut excessive manding and problem behavior within a few sessions by giving the client a way to predict what is coming.
Yes. Shorter components produce stronger contrast effects. Longer durations between transitions smooth out the motivational swings and reduce the magnitude of behavioral contrast.
