Abnormal Sensory Responsiveness
Abnormal Sensory Responsiveness
Studies suggest that many children with ASD show difficulty with sensory modulation. Further, some parents report that abnormal sensory responsiveness in their children affect their children's social, cognitive, and sensorimotor development.
Types of behaviors
Auditory stimuli
Both hyper-responsiveness to specific noises and under-responsiveness to noise has been reported in those with autism. Better than normal pitch has also been seen, and one study reported that there were disturbances in cognitive evoked potentials where subjects must give a specific response to a target stimulus and ignore another unusual stimulus in those with ASD. These disturbances suggested that there were alterations in attentional processing and auditory processing and identification. Some researchers suggest that atypical responses to auditory stimuli may lead some with ASD to behavior inappropriately.
