Consideration of Developmental Level in Applied Behavior Analysis Interventions

Terra is an 11-year-old girl with a moderate intellectual disability and Down’s syndrome. She lives with her Father, Mr. Q. Mr. Q is frustrated because Terra comes to breakfast each morning in her pajamas, with her hair uncombed despite Mr. Q’s laying out her clothes the night before and leaving her brush on the sink. Terra does get her teeth brushed on her own and will wash her face when reminded. Mr. Q states that he has to get to work and Terra’s not getting her clothes on and combing her hair is resulting in his being late to work three or more times per week.

Using the readings this week and any other additional sources you need, design an intervention that will assist Terra and her father. Discuss how Terra’s developmental level must be considered in order to plan and implement your intervention successfully.
