The majority of the participants' communication modalities was identified as oral or verbal (Arnold & Trembly 1979;Bobzien, et al, 2013;Brackett & Henniges, 1976;Brown, Prescott, Rickards, & Peterson, 1997;O'Connor, 1994;Darbyshire, 1977;Deluzio & Girolametta, 2011;Esposito & Koorland, 1989;Gatty, 1990;Higginbotham & Baker, 1981;Kretschmer, 1972;Levy-Shiff & Hoffman, 1985;Mann, 1984;Messenheimer-Young & Kretschmer, 1994;Minnett, et al, 1994 Another communication modality reported in the studies of play of children who are deaf play was sign language (Casby & McCormack 1985;Chapel, 2005;Pataki, Metz, & Metz, 2014;Quittner et al, 2016;Schirmer, 1989;Bilir & Bal, 1995). Some students had opportunities to use either signing or oral communication depending on the play context and play partners (Brunnberg, 2005;Cornelius & Hornett, 1990).…”
