This is the most memorable feature and if you were to describe the scene, that is what you would concentrate on. An autistic viewer might be struck equally by every single detail. The smoke and flames might be no more noteworthy than an unusual arrangement of roof tiles. It seems the autistic brain does not have an editor, so every bit of information is presented to the conscious mind. This is why autistic people tend to find new situations overwhelming.
Autism occurs in varying degrees.
At the mildest end are people with Asperger's Syndrome. They tend to be punctual, meticulous and often completely absorbed in a hobby such as model trains or computer programming. They have good memories and powers of concentration, but tend to be awkward in social situations whose unwritten rules they find incomprehensible. Difficulties with communication are a consistent feature of autism, although there is some evidence that autistic people may be able to communicate better with each other than with non-autistics. At the extreme end of the autistic spectrum are those who never learn to speak.
