Multiple Method Validation Study of Facilitated Communication: II. Individual Differences and Subgroup Results.
Peer reviewed Peer reviewed
Bebko, James M.; And Others – Journal of Autism and Developmental Disorders, 1996
Potential individual variations in the effectiveness of facilitated communication (FC) were examined with 20 students with autism and related disorders. Use of multiple methods (including auditory or visual input, simple point responses, and typing) provided no clear support for validity of FC over students' independent communication. Increased…
