Final answer:
Shaping, prompting, and chaining are evidenced based practices in ABA that help someone learn a new skill step by step.
Step-by-step explanation:
- Shaping is an evidenced based practice in ABA that helps someone learn a new skill step by step. It involves breaking down a complex behavior into small, achievable steps and reinforcing each step.
- Prompting is another evidenced based practice in ABA that involves providing cues or hints to help someone perform a desired behavior.
- Chaining is another method used in ABA to teach a complex behavior or a chain of behaviors by breaking them down into smaller components and teaching each component separately.
- Modeling, on the other hand, is a part of observational learning but not specifically an evidenced based practice in ABA that helps someone learn a new skill step by step.
