Post #2: Language Domains: Why We Need Each One in AAC

A typically-developing 18- to 24-month old child is an amazing being. At this stage, children begin to combine words (“Daddy up,” “Mama home,” “Want juice”), and then their language skills explode. They use the social skills they have been building since they were infants to map an ever-increasing vocabulary onto the sentences they are learning to use. That is, the four language domains are expanding and integrating at this stage:·

  • Pragmatics: social skills such as commenting, rejecting, socializing, and requesting
  • Semantics: vocabulary skills, including a range of parts of speech such as verbs, adjectives, adverbs, and articles
  • Syntax: sentence forms such as agent-action-object (“Rover lick face”),attribute-entity (“Big bowl”), and recurrence (“More juice”)
  • Morphology: word endings such as -ing (running), -ed (walked), and plural -s (apples)

All four of these domains are present in a simple sentence of a 19-month-old toddler. For example, if a child looks at his mother, points, and says, “Mommy’s cup!”, he has made a comment (pragmatics), used two different vocabulary words (semantics), indicated the relationship between those words (syntax), and used a grammatical marker to clearly indicate this relationship (morphology).

What about AAC?

Using and playing with language in these ways is crucial to the development of an intact language system. Determining how to mirror this process with children who need AAC is undeniably challenging, but we strongly believe there is no better model for supporting language development than by doing exactly that. Therefore, in our posts over the next two weeks, we will attempt to:

  1. (a) share some of our thoughts on how to consider using normal language development as a model for AAC service delivery,
  2. (b) explore the ways in which common AAC approaches currently are – and are not – adhering to this model, and
  3. (c) explore some ways to bring missing language
