title: Teaching the Conditional Use of Communicative Requests to Two School-Age Children With Severe Developmental Disabilities.
abstract: OBJECTIVE
  Two boys with severe developmental disabilities were taught to conditionally use requests to obtain desired snack items.
  
  
  METHODS
  When items were in the possession of another person (teacher, peer) or proximally distant, learners were taught to emit communicative requests. When items were proximally near, learners engaged in a self-selecting response.
  
  
  RESULTS
  Results suggest that the conditional discriminations were established quickly. Both learners generalized their conditional discriminations to other contexts within the classroom.
  
  
  CONCLUSIONS
  This study demonstrates the importance of attending to conditional discriminations when teaching communication requests.
