Describe two separate behaviors that would be good candidates for the use of an antecedent intervention through either the use of Non-Contingent Reinforcement (NCR) or the High Probability Request Sequence (HPRS). For each behavior, discuss the specifics of how you would use the antecedent intervention to change the behavior, and include details regarding whether or not the method of change which you selected used either abolishing operations or establishing operations, and why. Finally, describe how unintended consequences may arise when using antecedent interventions, any ethical, legal, individual, practical and/or social validity considerations that are unique to these approaches to behavior change, and why these methods of change are often combined with other intervention strategies.
