Children with frequent or severe repetitive behaviors may be more likely to have poor sensory responses than other children with autism.

This pilot study was designed to see if children who do the same movement or behavior over and over again (repetitive behavior) are more likely to have a poor sensory response. The data were taken from parent reports. The authors found that children with frequent/severe repetitive behavior and/or interests are more likely to have poor sensory response. This was the case for children with high as well as low IQ. These children are also more likely to receive drug therapy.
