title: Impact of PECS tablet computer app on receptive identification of pictures given a verbal stimulus.
abstract: OBJECTIVE
  The purpose of this brief report was to determine the effect on receptive identification of photos of a tablet computer-based augmentative and alternative communication (AAC) system with voice output.
  
  
  METHODS
  A multiple baseline single-case experimental design across vocabulary words was implemented. One participant, a preschool-aged boy with autism and little intelligible verbal language, was included in the study.
  
  
  RESULTS
  Although a functional relation between the intervention and the dependent variable was not established, the intervention did appear to result in mild improvement for two of the three vocabulary words selected.
  
  
  CONCLUSIONS
  The authors recommend further investigations of the collateral impacts of AAC on skills other than expressive language.
