“…Taylor, Hughes, and Richard (2004) taught teenagers with autism to respond to a vibrating pager when lost by going to the nearest adult and handing over a card requesting assistance. Other experimenters taught persons with autism or moderate cognitive disabilities to use mobile phones to obtain assistance when lost (Hoch, Taylor, & Rodriguez, 2009; Taber, Alberto, Hughes, & Seltzer, 2002; Taber, Alberto, Seltzer, & Hughes, 2003). The use of mobile phones and pagers is promising, but both strategies depend on the availability and proper use of technology, which may not be viable in all circumstances.…”
