During Discrete Trial Training (DTT) integrated with PECS, what is the PRIMARY purpose of systematically fading prompts?

The primary purpose of systematically fading prompts during Discrete Trial Training (DTT) integrated with Picture Exchange Communication System (PECS) is to promote the learner's independence in requesting items and communicating effectively without ongoing assistance. Let's break down each component to understand this fully. DTT is a structured teaching method used in Applied Behavior Analysis (ABA) to teach specific skills by breaking them down into small, manageable steps. Each 'trial' involves a clear instruction, a learner response, and immediate feedback. PECS is an augmentative and alternative communication (AAC) system where individuals use pictures to communicate their wants and needs.
