“…There are many descriptions of children using alternative communication in either segregated, partly segregated or nonsegregated educational settings (e.g., Basil & Soro-Camats, 1996;Baumgart, Johnson, & Helmstetter, 1990;Brekke & von Tetzchner, 2003;Buzolich, King, & Baroody, 1991;Calculator & Jorgensen, 1991;Campbell, 2002;Carter & Maxwell, 1998;Johnson, Baumgart, Helmstetter, & Curry, 1996;Light, 1985;McNaughton, 2003;Romski & Sevcik, 1996), but comparisons of children's development in different settings are lacking. To our knowledge, there are no published studies that compare the communicative interactions of children using alternative communication forms in segregated and non-segregated preschools and schools.…”
