- Visual impairment
- Lack of social interaction
- Delayed development of speech
- Stereotypic movements
Show Solution
The Correct Option is A
Solution and Explanation
Autism is best held in mind as a three-part definition: social deficits, communication and speech delay, and repetitive stereotyped behaviour. The except question simply asks which option falls outside that triad.
Run the choices through it. $Lack\ of\ social\ interaction$ is the heart of the social impairment. Delayed speech development is the communication/language strand. Stereotypic movements such as rocking and hand-flapping make up the repetitive-behaviour strand. All three are genuine, defining features.
Visual impairment is the outlier. It is a disorder of the eye or visual pathway and has no place in the core definition of autism. Autistic children typically see normally; what looks like avoidance of eye contact is a social-relatedness problem, not poor eyesight.
The feature that does not characterise autism is therefore visual impairment.
\[\boxed{Visual\ impairment}\]
