Psychological mirror test

The famous mirror test in psychology helps us to prove the process of baby's self-awareness. In the mirror test, psychologists put a red dot on the baby's nose, and then let the baby look at himself in the mirror. If they are babies without self-awareness, they don't know who they are in the mirror, so they reach out and touch the red dot in the mirror. A self-conscious baby already knows that it is himself in the mirror and will reach out and touch the red dot on his nose. Experiments show that babies usually develop self-awareness from 15 to 24 months. With the development of self-awareness, the baby gradually began to feel the ownership of his own goods. Babies in this period begin to be very attached to their toys and articles and are unwilling to share their things with others.
