유관적 택트 제공 절차가 자폐성장애 중학생의 음성 상동행동에 미치는 효과 = The Effects of Providing Contingent Tact Opportunities upon the Occurrence of Vocal Stereotypy for Two Middle School Students with ASD

다국어 초록 (Multilingual Abstract)

The experimenter examined the effects of applying a contingent tact opportunity procedure upon the emission of vocal stereotypy on the subsequent occurrence of mands, and tacts emitted in a non-instructional setting for two middle school aged participants diagnosed with an Autism Spectrum Disorder (ASD). The dependent variables of this current study were the rate of the frequency of vocal stereotypy, tacts, and mands emitted during experimental sessions conducted in non-instruction settings. The independent variable was the implementation of a contingent tact opportunity procedure in which tact opportunities were delivered contingent on instances of stereotypy. A time delayed multiple baseline across participants design was utilized to analyze the functional relationship between the dependent and independent variables. The results showed that the contingent tact opportunity procedure effectively decreased stereotypy for both participants, and for one participant, showed more independent tacts and mands. These results provide evidence that skill developing procedures can effectively treat stereotypy.
