Extinction (EXT)

Extinction is a behavioral principle that can be used to decrease or eliminate an interfering behavior by withholding the consequences that are maintaining it.

What Will I Learn?

The AFIRM model guides the learner through four lessons to facilitate:

  • Learning basic knowledge about extinction (EXT).
  • Applying EXT in activity based scenarios that promote real-world application.

The EXT module will take approximately 1.5 to 2 hours to complete. However, the module is broken into individual lessons to help guide your learning:

Lesson Time to Complete
A Case for EXT 10 minutes
Lesson 1: Basics of EXT 20 minutes
Lesson 2: Planning for EXT 25 minutes
Lesson 3: Using EXT 45 minutes
Lesson 4: Monitoring EXT 25 minutes
