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
Applying EXT 10 minutes

If you leave the module prior to finishing, your place within the module will be saved. From your My Account page, look in the My Modules tab and select the last page viewed to resume this module.
