Phase II Procedures
Purpose: Learners are taught to gain the attention of a communication partner
using a single switch voice output device.
1. *Phase 1 and Phase 2 procedures are the same, except that now a switch is
introduced that needs to be taught. The purpose of the switch is so the
learner with VI can call a communication partner over to them, instead of
travelling to find a communication partner. This allows the intervention to
be accessible to learners who may not be independent travelers due to their
VI or a motor impairment that limits mobility.
2. *After the child reaches for the symbol or reinforcer, the prompter
immediately provides physical assistance, so the child activates the voice
output switch and then pick up the symbol, reach, and release. The prompter
should try to allow the child to complete the pick-up, reach, and release
independently if possible.
3. *As the learner demonstrates mastery of the new sequence, the CP will
begin increasing the distance between themselves and the learner, so they
learn to tolerate waiting for the CP to travel to them and complete the
exchange.
