These SIG 12 Perspectives articles provide information on current issues associated with visual processing of augmentative and alternative communication (AAC) displays for people with traumatic brain injury, assessment of the expressive language abilities of Spanish-speaking children who rely on AAC, and culturally sensitive approaches to aided language modeling. Readers will be more adept at designing effective AAC displays for adults with traumatic brain injury and at providing AAC services to children from multilingual and multicultural backgrounds.

You will be able to:

• explain how adults with traumatic brain injury attend to and visually process grid displays
• describe methods used to assess the expressive language of Spanishspeaking children who use aided AAC
• discuss the effects of aided modeling on language expression of children from multilingual and multicultural backgrounds
