This video shows how to do Phase 3 intervention for individuals with non-verbal autism or little to no functional speech when using the SPEAKall! app for iPad. During this phase, the participant learns to discriminate between various graphic symbols. This is video #3 from a series of five videos demonstrating one possible instructional approach to use with the SPEAKall! app. The approach shown here is derived from exchange-based communication such as the Picture Exchange Communication System.
