Problem: Write appropriate experimental questions for the proposed research study.
Scenario: You are a BCBA working with Hanna, a 27-year-old diagnosed with a traumatic brain injury.
During periods of instruction (lasting 60 min in length), Hanna will become aggressive (a variety of topographies are exhibited) when she is having difficulty with a task or has decided she no longer wants to complete it. Based on a functional behavior assessment, you have determined the aggression is maintained by escape. The interdisciplinary team you work with believes escape extinction is not the best option for Hannah and would like to implement an antecedent-based intervention combined with reinforcement for compliance and task completion to reduce aggression. You are unsure which antecedent-intervention may be best; however, you would like to implement both activity choice and noncontingent escape and see which reduces aggression more. To see which works best, each procedure will be conducted in a different treatment room (activity choice in the blue room and noncontingent escape in the yellow room) so there is a clear way for Hannah to discriminate the procedures. During activity choice, Hanna will be given choices about the types of activities that will be conducted that day along with the stimuli used during the activities. During noncontingent escape, Hanna will be given a 2-min break after
