Social Positioning to Increase Communication of Adults With Extensive Support Needs.

Social positioning involves positioning individuals with extensive support needs (ESN) in proximity to and facing a communication partner, with access to a speech-generating device (SGD). We used a multiple probe design to evaluate if social positioning would increase the symbolic and nonsymbolic communication of 10 adults with ESN when they were out of their wheelchairs. Dependent variables included (a) SGD activations, (b) eye gaze, (c) vocalizations, and (d) reaching.
