Perseveration on Interests and Activities

Children with autism typically have a narrow range of interests (e.g. will only go to play in the block area of classroom). They may also engage in repetitive, stereotyped body movements such as hand flicking, spinning or rocking. They may insist on carrying certain objects around with them in the classroom to keep themselves from tantrumming or to help them feel secure. Perseverations might extend to food. A child with autism may have a preference or dislike certain colours, textures or temperatures of foods. Some individuals perseverate on certain topics. A child might remain intrigued with one or two topics, such as music or modes of transportation, and exhaust everyone who comes into contact with him about his knowledge in that area of interest.
