Autism Therapy: interspersal procedure

Sensory-based activities may help some children with autism stay focused on a task.

Children with autism may have sensory integration problems that make it hard to focus on school work and come up with the right answer. Some therapists use sensory activities that may help children with these problems. For example, children may swing slowly on a swing or bounce quickly on an exercise ball. Usually the children enjoy the sensory activities very much. The researchers wanted to find out if a reward system would motivate children to give correct answers to some questions. Three children (ages 6-7) were offered a choice of sensory activities to do before a session. That activity would then be their reward for answering 12 correct answers. The session started when the therapist asked the child to open their workbook. As their task, children were then asked to identify pictures of community helpers and safety. The children earned a token for every correct answer. They needed to earn 12 tokens in order to get the reward of going on the swing or the exercise ball. The researchers added an interspersal procedure by mixing questions that the child clearly knew the answer to with others that they might need to learn the answer to. The sensory activities as rewards helped two of the three children give correct answers when asked to identify what was in the picture. The interspersal procedure also helped motivate children to give the correct answers.
