S​‌‍‍‍‌‍‍‌‍‌‌‍‍‍‌‍‌‌‌‍​etting the Scene: Freddie is a 7-year old second grader. He was diagnosed with autism when he was 2 years old. Freddie has a loving family that consists of his mother, father, and two older brothers. Recently, Freddie woke up in the middle of the night in terrible pain — it was a severe toothache. His parents took him to a pediatric dentist, Dr. Jim, who told them that Freddie had an abscess of his second molar of the right upper jaw. Thankfully, this was a baby tooth and would have been lost by, at the latest, 12 years of age. The parents explained that Freddie is very resistant to brushing his teeth, or even having his parents brush his teeth. They expressed great concern about his health and the impact his oral hygiene would have. Dr. Jim told Freddie’s parents that he had seen many cases just like Freddie’s and that he always refers his patients who have this “resistance” to a BCBA who designs individualized skill acquisition programs to increase independence in brushing teeth, as well as reduce the resistance. Freddie’s parents were thrilled to learn that there is this type of help available to them — for Freddie’s oral hygiene and other activities of daily life with which Freddie struggles. This could help Freddie in so many ways! PROPOSED CHAINING First when it comes to producing a chainin​‌‍‍‍‌‍‍‌‍‌‌‍‍‍‌‍‌‌‌‍​g for Freddie to learn how to brush his teeth. We will conduct a task analysis to where we identify all the individual behaviors that we would be doing in order to complete the ultimate task of brushing his teeth. 1. Remove cap from toothpaste 2. Grab toothbrush and toothpaste. 3. Squeeze small amount of paste onto toothbrush 4. Dampen the bristles of brush with water 5. Place brush in mouth 6. Brush all teeth 7. Spit foam into sink 8. Rinse toothbrush in sink I feel like the best type of chaining procedure to be using with this type of skill or task would be forward chaining. so, we’ll start from one by teaching them how to perform that behavior by using prompting and fading. We’ll be using positive reinforcement either through verbally, small little prizes, or certain reinforcers that Freddie would prefer as he masters each behavior. we’ll do this until he is able to complete all 8 behaviors independently. we need to make sure that when we’re doing this that we involve fading to where Freddie won’t need any more prompts as well as generalization so it becomes a general task for him to do. NOW: Respond to the proposed above plan by choosing a chaining procedure that is different from the one they chose to train teeth brushing, and explain the process of chaining using the task analysis that the peer descr​‌‍‍‍‌‍‍‌‍‌‌‍‍‍‌‍‌‌‌‍​ibed.
