When children are attacked, they either lash out or they withdraw. This goes for verbal attacks as well as physical. Since children are incapable of striking back at an adult, they tend to do so with peers. But aggression, whether verbal or physical, doesn't just injure the target. There are serious consequences for the aggressor as well, such as rejection from peers, higher levels of loneliness, depression, and negative self-perceptions. (Crick & Grotpeter, 1995)
This leads to peer problems. Children who either withdraw or lash out have trouble making friends. Guess what happens then? Children with peer problems begin to feel defective and less adequate, thereby attacking their self-esteem even more. The cycle of inadequacy escalates and continues.
Hypersensitivity is a common outcome in verbal abuse, because those who verbally abuse children generally do so out of habit, often without even realizing the extent to which their barbed remarks impact the child. More often than not, they don't consider the acts to be abusive. So children who are subjected to verbal abuse are usually done so repeatedly, and hypersensitivity develops as a result in almost every case.
This means that children become overly sensitive to any signs of rejection or disapproval. Hypersensitivity from verbal abuse is by far the most debilitating type of hypersensitivity there is, and it will hinder them for the rest of their lives or until they have it corrected. Criticism and measuring sticks are easy to come by in our society, so there is no shortage of activating events. You might as well double or triple their lifelong stress, because until it is corrected (and this is one of the harder issues to correct) they will be overly sensitive to any hint of inferiority or criticism, which will release a flood of Cortisol to stress out their brains.
In addition to the added stress, here are some other issues that hypersensitivity to ridicule causes:
