Abstract:
Skinner’s theory of verbal behaviour, particularly the assertion of unique controlling conditions for each verbal operant, has allowed for the investigation of possible functions of verbal responses. Research by Lerman, Parten, Addison, Vorndran, Volkert and Kodak (2005) used functional analysis methods to assess the elementary functions (mand, tact, intraverbal, echoic) of emerging language in children with developmental disabilities.
