“…Because aberrant and/or idiosyncratic behaviors evidently differ from pre-linguistic forms of communication, which constitute precursors of linguistic forms of reference and communication in typical speech-language acquisition, they should perhaps be labeled and treated differently and more tentatively interpreted as forms of communication. Thus, when it comes to describing the socio-pragmatic functions of individuals with such extreme communicative restrictions, it may be best to refer to such behaviors as “potential communicative acts” (as suggested by Sigafoos, Woodyatt, Keen, et al, 2000 ) instead of non-symbolic or pre-linguistic forms of communication ( Didden et al, 2010; Siegel-Causey & Guess, 1989; von Tetzchner et al, 1996 ).…”
