A minimum of 350 words required with references. Please answer all questions.

Part 1: Based upon a functional assessment, you have chosen to use habit reversal procedures to decrease the thumb sucking behavior of a 7-year-old child. Explain how you would implement all four components of habit reversal with this child, including a specific competing response. Provide a description of why habit reversal procedures work to reduce habit behaviors (include the applicable behavioral principles).
