Behavioral Cusp

Behavioral Cusp means a behavior that opens access to new environments, reinforcers, or learning opportunities, leading to larger developmental changes.

Application in ABA and RBT Practice
RBTs prioritize skills that create the biggest impact, such as communication, mobility, or social interaction. These cusps accelerate learning by expanding what the learner can access.

Examples
• Learning to walk opens opportunities to explore and play.
• Learning to read signs increases independence in the community.

Why It Matters
Focusing on cusps makes treatment efficient and future-oriented rather than just short-term.

Common Mistakes
Confusing a cusp with any new skill; cusps must unlock broader opportunities, not just isolated changes.
