This scenario describes a classic example of behavior contrast and the professional responsibility to anticipate and address it Behavior Contrast This phenomenon occurs when the rate of a behavior changes in one setting in the opposite direction from the change in rate of the same behavior in another setting In this case the rate of manding has increased at home due to the introduction of reinforcement token economy In the school setting where no such reinforcement is provided or potentially where the baseline level of reinforcement for manding remains unchanged or even becomes relatively less appealing compared to home the rate of manding for the client is likely to decrease This is because the value or effectiveness of reinforcement for manding at school is reduced relative to the richer reinforcement schedule available at home Immediate Action The BCBAs immediate action should be to inform the school staff about this potential phenomenon Proactive communication is essential for continuity of care and preventing unintended behavioral effects Warning the school allows them to be prepared monitor the behavior and potentially begin planning for an intervention to generalize the manding behavior to the school setting or prevent its decrease Why other options are incorrect Extinction burst Immediately inform the school that manding may temporarily increase as the client attempts to access reinforcement An extinction burst occurs when reinforcement for a previously reinforced behavior is withheld leading to a temporary increase in the rate intensity or variability of the behavior In this scenario reinforcement for manding is not being withheld at school rather there is just no new intervention and the behavior is being highly reinforced at home Therefore an extinction burst is not the expected outcome Spontaneous recovery Advise the school to monitor for a sudden reemergence of previous inappropriate mands after a period of absence Spontaneous recovery refers to the reappearance of an extinguished behavior after a period during which the behavior has not been possible or has not occurred This is not applicable here as the focus is on the current state of appropriate manding not the reemergence of a previously extinguished inappropriate behavior Response generalization Inform the school that appropriate mands are likely to spontaneously appear there without any intervention Response generalization refers to the spread of a behavior change to untrained responses that are functionally similar to the trained response While generalization to other settings is a goal it rarely occurs spontaneously without some level of planning or programming for generalization across environments especially when a strong differential reinforcement contingency is established in one setting but not another Behavior contrast is a more likely initial outcome in this situation
