Description of Research Report: Tangible Object Symbols: A Case Study with an Adult with Multiple Disabilities
For special educators and speech-language pathologists who work among adults with multiple disabilities, tangible object symbols may be an appropriate avenue for communication enhancement. Many of these adults use presymbolic communicative actions (Cascella, 2005), and these symbols may enable them to transition from presymbolic into symbolic communication. Collateral evidence for this transition comes from promising results of tangible symbol applications among children who also have presymbolic communication actions (Parker, Banda, Davidson, & Liu-Gitz, 2010; Rowland & Schweigert, 2000; Sigafoos et al., 2008; Trief, Cascella, & Bruce, 2013). Yet, there is a paucity of research on tangible symbol treatments among adults.
