The October 11, ASHA Leader offers a synopsis of findings from the attached Review of Literature (link to Leader):

     "In the studies, individuals were taught to use speech-generating devices (SGDs), picture exchange (PE) systems, and/or manual signs. Sixty-seven percent of participants demonstrated some degree (≥55%) of preference for using SGDs; 33% demonstrated some degree (≥55%) of preference for PE. The results indicate that individuals with developmental disabilities may show a preference for different AAC options, and that incorporating these preferences may enable individuals to exert self-determination with respect to AAC intervention."
