Association for Behavior Analysis International

This symposium contains three presentations regarding improving social functioning for children with autism by teaching them important skills. The first paper involves teaching basic skills of understanding perspective taking. The second presentation is teaching the identification of false-belief tasks, which are commonly used by developmental/cognitive psychologist to test the ability of "theory of mind." The third presentation uses an evaluation form along with video modeling to train parents how to teach their children with autism.

Previous research has reported that the inability of children with autism to discriminate between the reality and non-reality of events may contribute to their difficulties in understanding others perspectives. The purpose of this study is to use behavior analytic approach to teach children with autism to tact mental vs. physical state of verb. A seven year-old child with autism, who had advanced speaker and listener repertoires, participated in this study. A multiple probe across three behaviors design was used. Three target behaviors included (a) discrimination of physical and mental states of events (e.g., Tony takes a train in his hands. Kevin is thinking about the train. Who has the train?) (b) discrimination of reality and imagination (e.g., Mary locked the door. Tim wanted to lock the door. Who indeed lock the door?), and (c) discrimination of reality with and without evidence (e.g., John saw the candy on the table. Helen heard that the candy is on the table and believes the candy is on the table. Who can get the candy for sure?) Multiple exemplar teaching strategy with picture stimuli along with verbal instructions were used during training. Data showed that the rate of correct responses was increased after training. The skills were also generalized to novel scenarios.

Children with autism often have difficulty taking others' perspective--a developmental capacity commonly observed in typically developing children, termed the theory-of-mind (ToM). Teaching the children to tact other's belief is the fundamental skill in ToM. The purpose of this study is to use behavior analytic approach to teach children with autism to identify false-belief tasks. Two children, age 6-7 diagnosed with autism, who had advanced speaker repertoires, participated in this study. A combination of multiple probes across subjects and behaviors was used. Ten scenarios with pictures illustrating the stories were created as instruction materials. The teaching procedure included showing the scenario with drawn pictures, and asking questions regarding the belief of each person. Two target behaviors included:(a) tacting other's belief, (e.g., John is looking for his pencil box. Pencil box may be on the shelf or dining table. John thinks that it should be on the shelf. Where is John going to find his pencil box? Why?) (b) tacting other's false belief (e.g., John is looking for his pencil box that he left on the dinning table. Mary has put John's pencil box on the shelf. Where is John going to find his pencil box? Why?) Both children showed positive results for the acquisition and generalization of the tasks.

The study was conducted in an Early Intensive Behavioral Intervention (EIBI) program of a public children's hospital in the Seoul city. Three mothers whose children were receiving the EIBI service participated in the study. A multiple baseline across participants design was used in the study. During the baseline, a behavioral skill training package was implemented in which lecture, written instruction, modeling, coaching, role-playing, and feedback were provided to the parent during DTT sessions. During the intervention phase, parents were required to watch their performance video scoring their own performance with TPRA forms. Percent of trials which were delivered without errors and rate of delivery of correct trials were measured using TPRA, and overall performance during DTT were evaluated using "Performance Checklist" throughout the study. The results showed that video self-monitoring using TPRA forms were effective in improving parents' performance during DTT with their children with ASD. The improved performance of parents during DTT was maintained during follow-up sessions.
