Nowadays, some small stores or toy stores often sell some hideous-looking monsters, ugly monsters and other toys. As children like, some parents are also happy to buy for their children to play. In fact, let young children play with ugly toys, may have a negative impact on the physical and mental health of children. The reason is that the formation of children’s values and aesthetics is always closely related to the things and objects they are exposed to from childhood. Because children have limited ability to discriminate, if we provide children with toys that are ugly, or with violent or bloody overtones, then children will naturally assume that this is an adult-approved way of behaving, and they are likely to imitate it up in their daily lives, consciously or unconsciously, to produce some aggressive behavior. Studies have shown that often let children play with some “cathartic toys” (refers to the toys can be used as a catharsis of the inner psychological tension of young children) will indeed enhance the child’s aggressiveness. For example: parents to buy boys simulation pistols, swords, swords and other toys, children are prone to use these “weapons” in the game against their peers; some made into ugly animal toys, the children see the disgust, fear, and more like to grunt to knock hard on these toys. This “animal cruelty” behavior, children may have the desire to bully the weak from an early age, planting the “seeds of hatred”, but also easy to develop a child’s aggressive, aggressive behavior. Studies have also found that children who are withdrawn and do not get along seem to be more likely to become obsessed with such toys, which can contribute to their withdrawn and introverted personalities and can have a negative impact on their mental health.
