Psychologists have debated a long time about whether a child’s upbringing can give it the ability to do outstandingly well. Some think that it is impossible to develop genius and say that it is simply something a person is born with. Others, however, argue that the potential for great achievement can be develop. The truth lies somewhere between these two extremes.

It seems very obvious that being born with the right qualities from gifted parents will increase a child’s ability to do well. However, this ability will be fully realized only with the right upbringing and opportunities. As one psychologist says, “To have a fast car, you need both a good engine and fuel”.

Scientists have recently assessed intelligence, achievement, and ability in 50 sets of identical twins that were separated shortly birth and brought up by different parents. They found that achievement was based on intelligence, and later influenced by the child’s environment.

One case involving very intelligent twins was quoted. One of the twins received a normal upbringing, and performed well. The other twin, however, was brought up by extremely supportive parents and given every

possible opportunity to develop its abilities. That twin, thought starting out with the same degree of intelligence as the other, performed even better.

This case reflects the general principle of intelligence and ability. The more favorable the environment, the more a child’s intelligence and ability are developed. However, there is no link between intelligence and socioeconomic level of a child’s family. In other words, it does not matter how poor or how rich a family is, as this does not affect the intelligence.

Gifted people cannot be created by supportive parents, but they can be developed by them. One professor of music said that outstanding musicians usually started two or three years earlier than ordinary performers, often because their parents had recognized their ability. These musicians then needed at least ten years’ hard work and training in order to reach the level they were capable of attaining.

People who want to have very gifted children are given the following advice: ·      Marry an intelligent person.

·      Allow children to follow their own interests rather than the interests of the parents.

·      Start a child’s education early but avoid pushing the child too hard.

·      Encourage children to play; for example, playing with musical instrument is essential for a child who wants to become an outstanding musician.

When scientists studied intelligence and ability in twins, they found that _______. 

A. ability depends mainly on intelligence and achievement 

B. intelligence and development are irrelevant to ability 

C. ability depends both on intelligence and environment 

D. different twins generally have different levels of ability

          Body language is a vital form of communication. In fact, it is believed that the various forms of body language contribute about 70 percent to our comprehension. It is important to note, however, that body languages varies in different cultures. Take for example, eye movement. In the USA a child is expected to look directly at a parent or teacher who is scolding him/her. In other cultures the opposite is true. Looking directly at a teacher or parent in such a situation is considered a sign of disrespect.

          Another form of body language that is used differently, depending on the culture, is distance. In North America people don’t generally stand as close to each other as in South America. Two North Americans who don’t know each other well will keep a distance of four feet between them, whereas South Americans in the same situation will stand two to three feet apart. North Americans will stand closer than two feet apart only if they are having a confidential conversation or if there is intimacy between them.

          Gestures are often used to communicate. We point a finger, raise an eyebrow, wave an arm – or move any other part of the body - to show what we want to say. However, this does not mean that people all over the world use the same gestures to express the same meanings. Very often we find that the same gestures can communicate different meanings, depending on the country. An example of a gesture that could be misinterpreted is sticking out the tongue. In many cultures it is a sign of making a mistake, but in some places it communicates ridicule.

          The dangers of misunderstanding one another are great. Obviously, it is not enough to learn the language of another culture. You must also learn its non-verbal signals if you want to communicate successfully.
