Many people become quiet and tense when they first meet someone they do not know, or when they face a new situation. They become(36)worried, or even afraid. Their hearts beat more quickly. They begin to(37)sweat. They may have some trouble breathing(38)normally. They have(39)difficulty thinking of what to say. They even may forget the name of the person they just met. We say these people are shy. Many doctors use the word "inhibited". About 40 percent of persons questioned in one study(40)described themselves as shy. They said the shyness is so severe that it(41)interferes with their school, work or social life. Doctors believe that(42)generally people become shy as children. Children learn from their parents to be especially(43)careful in situations that might have dangers. Some children may be born shy. Psychiatrist Stella Chess studied a group of children from birth.(44)She found major differences in the way babies deal with new situations. Some accept changes very easily. Others have great trouble with any new event.(45)Another scientist says it appears that about ten percent of American babies are naturally very brave, and another ten percent seem to be naturally very fearful, very shy. All children seem to react in similar ways when they are afraid. One part of the brain sends signals to different parts of the body. These signals tell the heart to beat faster, make muscles tense. Shyness can be overcome.(46)Parents can gently help their children meet other persons and enjoy new events and situations.
