1) Stereotype cognition:
A typical feature of autistic thinking is rigidity, and it has a strong obsession with some rules or the order of objects. For them, once something similar to habit is formed, what they should do cannot be changed. This is somewhat similar to what we usually call incomprehensible flexibility.
The thinking extraction of autistic people is mainly based on pictures, which is why it is much more effective to use pictures than words when communicating with autistic people. For example, if you give a picture of a dog, autism will present all the images related to dogs in your brain. However, the retrieval of ordinary people is often based on words, and the information presented is often some general things.
2) Independence and irrelevance in the process of thinking processing;
This mainly means that when presenting a group of objects to autistic children, in their eyes, there is no relationship between each object in this group, such as the scene of a family of three chatting together. For autistic children, the thinking process is not a whole picture, but an independent and irrelevant part, that is, there are fathers, mothers and children in this scene, and there is no relationship between them. For another example, if autistic children are presented with a set of pictures in turn, such as three pictures representing different steps of dressing (the first one: putting on sleeves, the second one: buttoning up, and the third one: tidying up collars). For them, the sequence of these three steps has no concept, except that three people with similar looks are doing three different things respectively.
3) De-emotionalization:
In the thinking process of autistic children, the received facial information will be expressed. Simply put, in the eyes of autistic children, everyone has only one expression, similar to a blank sheet of paper. They can't understand the emotions contained in expressions from the differences in expressions. This also exists in the language processing of autistic children, that is, they can't understand what others want to convey in their language, such as understanding rhetorical questions and stating tone.
4) single-threaded processing:
Strictly speaking, this is actually a rigid performance. Compared with ordinary people who can handle several different things at the same time, autistic children can only handle one thing at a time. This is because under the influence of rigid thinking, we must abide by some fixed rules or processes. If you deal with another thing at the same time, it is obviously contradictory to the established steps. For autistic children, this means that this thing has failed.
