  • Assessment/Diagnosis
    • Assessment Areas
      • Speech & Language
        • AAC - Grammar skills should be assessed in individuals using augmentative and alternative communication.
  • Treatment
    • Language
      • Speech & Language
        • General Findings - A number of interventions used with individuals with language disorders can be adapted for individuals with SSPI (e.g., models, contingent queries, recast expansion, forced choice alternative questions, correction of incorrect form and explanations of grammatical rules).
        • AAC - The findings suggest that some individuals using augmentative and alternative communication may have grammar deficits and intervention techniques focusing on grammar may be warranted.
