Autism Spectrum Disorder (ASD)

Social interaction - Problems engaging in reciprocal social interactions The severely affected child will seem aloof and uninterested in people where as a child less affected passively accepts social contact, even showing some pleasure in it, though he/she will not make spontaneous approaches.

Social communication -
A significant proportion of children people fail to develop useful speech. If language is used, there is a failure to understand the various uses of communication. Some will communicate for their own needs but will have difficulty in talking about feelings or thoughts and in understanding the emotions, ideas and beliefs of other people.

Social imagination -
Inability to play imaginatively with objects/toys and children/adults. Pretend play can be absent or repetitive in children with autism. A tendency to pay focused attention to minor or trivial aspects of things in the environment instead of an imaginative understanding of the meaning of the whole scene is often found. E.g. the child may spend long hours looking at the wheels of a car without actually playing with the car. Some imaginative activities may be displayed but these are usually copied, for example from TV programs (cartoons). This play may seem complex, but careful observation shows its rigidity and stereotyped nature.
