Provide an example of two different behavior change strategies (e.g., – response cost, positive reinforcement, non-contingent reinforcement, negative punishment, etc.) where an unwanted behavior change might occur as a result of your treatment intervention. Using behavior analytic terms, discuss the specific tactic that was used, the target behavior, and the unwanted behavior change. How could you have planned for this differently? Are there any ethical, legal, practical, individual and/or social validity considerations to go along with each method of change which you described?
