Speech disorder
Some autistic children do not speak at all, while others are far behind their peers in speech development. Children under the age of 12 months do not walk, tend to repeat the same sounds (?), at 2 years old they have an extremely poor vocabulary (about 15 words), and by 3 years old they are almost unable to combine words. Other autistic children can repeat words and phrases heard somewhere like an echo, invent their own words (neologisms), while many do not use speech for communication. Autistic people refer to themselves in the third person and do not use titles or personal pronouns.
Lack of emotional connection
Lack of emotional connection with people, especially with parents. Toddlers with autism do not look people in the eyes, do not reach for their parents in their arms, do not smile. Autistic people often resist parents’ attempts to pick them up and caress them. From a behavioral perspective, such children are similar to the deaf or blind: they do not distinguish their parents from other people and they do not notice that someone is addressing them.
Problems in socialization
Being among others, a child with autism experiences severe discomfort, and over the years develops social anxiety. “Indigo children” (??) can run and hide if someone has actively addressed them. They do not know how to play with their peers, they cannot build friendships, because they do not understand the emotions of other people, unfamiliar with the rules of the game. Autistic people prefer solitude, which protects them from strong feelings about their inability to communicate.
Attacks of aggression
Any disorder, failure can cause a child to have an outburst of anger, provoke a tantrum or a physical attack. Aggression in autistic children can be directed at others and at themselves; the latter was recorded in 30% of patients.
Weak interest in toys
A child with autism does not know how to play with different objects, such as cars and dolls. Such children are usually uncapable of symbolic actions; in other words, they cannot depict some objects with the help of others, due to poorly developed abstract thinking.
Stereotypical behavior, fear of change
Autistic children tend to do the same things for a long time: repeating the same word, running in circles, swaying from side to side, looking at rotating objects, twirling something etc. They are characterized by adherence to certain rules and/or a routine. If this routine is violated, they are very worried, they resist change, and fall into aggression.
