Why does my autistic son cover his ears? it has nothing to do with loud sounds. he usually does it while watching tv even if the sound is low.

Over stimulated: As kids have sensory guarding. Their perception of the verbal/auditory world is different and heightened. Mannerisms of coping often deteriorate into self stimulation activity. This happens with taste and touch as well (licking, smelling, tasting all manner of things). But does not usually happen in the visual realm, which is their strength.

See below: People with pervasive developmental disorders such as autism can engage in repetitive, stereotyped behaviors that don't appear to be related to their external world (eg sound level). These behaviors can be relatively complex such as covering one's ears. This may represent an inflexible routine associated with sitting in front of the television. Consider reviewing further with a doctor.

Although not in DSM : Criteria for autistic disorder, over- or under-reacting to any of the 5 senses is an atypical behavior seen in children with ad, as are lack of theory of mind (understanding that others can have a different point of view than his) & lack of facial recognition ("reading" facial expressions). Use screen time only as a reward for eye contact, compliance, turn-taking, or joint attention, max. 2 hrs/d.
