This week’s Reading will center on considerations in measuring treatment effectiveness through analyzing graphs and evaluation of reversal designs. The Reading also highlights ethical considerations as they pertain to the use of reversal designs.Read the following chapters in your Applied Behavior Analysis text:Chapter 6: “Constructing and Interpreting Graphic Displays of Behavioral Data” (pp. 126–132)Chapter 8: “Reversal and Alternating Treatment Designs” (pp. 176–187)Read the following chapter in your Ethics for Behavior Analysts text:Chapter 16: “Conducting a Risk-Benefit Analysis”Data Analysis and Evaluation-250 words book reference onlyScenario: Recall the scenario from the Unit 4 Learning Activity. To recap, Sherry is a 15-year-old girl diagnosed with autism and severe intellectual disabilities. Her IEP team met to discuss significant behavior problems in the form of hand biting that has resulted in significant tissue damage requiring medical attention. Prior interventions attempted by the school staff were response blocking, physical restraint, and mechanical restraint (arm splints). An initial functional behavioral assessment conducted by the consulting BCBA revealed that the apparent function of hand biting was negative reinforcement in the form of escape from task demands. Based on this assessment, the BCBA developed a differential reinforcement of alternative behavior (DRA) intervention in which Sherry was taught to use her hand to squeeze a stress ball when non-preferred demands were presented. The teacher and other individuals involved with Sherry were trained to allow immediate escape whenever Sherry squeezed the stress ball during instruction. In addition, instructional material was altered so that the learning tasks were easier with the goal of gradually increasing difficulty. Baseline data (pre-intervention) had already been taken for 10 days and the DRA intervention was implemented on day 11. On day 21, the BCBA employed a reversal design in which the intervention was stopped to verify that it was indeed the intervention that was responsible for the behavior change. Please review the graph, which represents Sherry’s overall response to intervention, and answer the following questions:According to your readings, what are the six primary benefits of using graphs as a tool to measure the effectiveness of interventions, and why are they important? Discuss two of the benefits that you feel are most relevant to the current case and explain your reasons for your choicesBased on your observation of the data represented in the graph, what is your impression of the effectiveness of the DRA intervention? Discuss the purpose of the reversal design and indicate the type of reversal design indicated in the graph. What are some of the potential risks and benefits of using the reversal design in the current scenario? (Indicate at least one ethical issue in your discussion.)part 2- Complete the templatehttps://kapextmediassl-a.akamaihd.net/artsSCi/PS38…For this Learning Activity, please review The Use of Reversal Designs for Functional Analysis video.
