In order to explain and examine the emergence of self-recognition in infants, various studies such as the research described below have been carried out for many years. Therefore, there is a general consensus that babies at 15 months of age and babies at 24 months of age can react to their images using mirrors (Anderson, 2005). Studies have shown that there are various self-recognition reactions and self-labeling. This shows that infants recognize themselves in the second year, but further research is needed to verify their effectiveness.
When a child is a baby and a child, it builds the foundation for self-awareness. At these stages, children learn "what is me" and "what is not me". Infants are sensitive to the feelings of the surrounding adults and begin to imitate the behavior of adults. By the time they become two years old, children will recognize and explore the differences in the body. They are also learning the color names and they are beginning to apply them to the skin tones. Natural curiosity may lead to doubts about differences. Preschool children (3 years and 4 years old). Children of this age are more adept at noticing people's differences. They learned to classify and they tend to classify by color and size. They are still confused about the ethnic group's name and the actual color of the skin as they can not handle multiple classifications yet. They want to know why two people with different skin colors are considered as members of the same ethnic group.
Abused children are often cautious about their environment and others' feelings. They are focusing on the appearance rather than typical young children (they are very self-centered) and can not separate themselves into individuals or can not consider themselves to be different creatures maybe. In this way, abused children can not concentrate on work in front of others because they are too worried about the reactions of others. They are not playing with toys, they are not interested in exploring and they do not seem to be able to enjoy life either. They may accept losses with little response and may have knowledge of sexual and sexual relations not suitable for age. Finally, young children begin to reflect their parents' behavior regardless of whether they are abused or not. As a result, an abused infant may mimic abuse while playing with a doll or "playhouse".
