Gender IQ
- IQ is a measure which indicates the human’s intelligence.
- It is generally believed that the higher IQs people have, the more success they achieve.
- There are many factors affecting intellectual abilities.
- Some of them are heredity and environment.
- First, hereditary factor plays an important role in the human’s intelligence.
- Most researchers believe that heredity’s influence on intelligence is between 60 percent and 80 percent.
- Through hereditary process, mental and physical characteristics are passed from parents to their children.
- Francis Galton (1885) – an English psychologist demonstrated convincingly that intelligence is mostly inherited.
- His researches pointed out that children whose parents have high IQs are more intelligent than ones whose parents have lower IQs.
- Besides, if parents have special abilities, their children will also have them.
- Moreover, according to Adoption studies, the adopted children somewhat are similar with their adoptive parents in intelligence.
- Apart from looking at the parents IQs, twin’s intelligence also contributes to the genetic debate.
- Studies about intelligence of Arthur Jensen - a professor of educational psychology at the University of California showed that the IQ levels of identical twins are 32% more similar than the IQ levels of fraternal twins.
- He also found that the IQ levels of identical twins reared together are just 11% more similar than the IQ levels of identical twins reared apart.
- Second, environmental effects leave a consequence in human IQ.
- They contain many factors such as family, community and education.
- The environment provides human with knowledge and experience for intellectual development.
- People live and grow in their own environment that obviously creates distinctions in their abilities.
- For example, Lewis Terman (1877-1956) – an famous American psychologist, known as president of the American Psychological Association figured out that children who live in a happy family and be well-educated tend to have higher IQs than homeless children because the environment affects their emotions, motivations and beliefs, which are closely related to intellectual competence.
- In conclusion, it is evident that human IQs depend on variety of factors.
- Parents should have more positive effects to improve their children’s intelligence. Nana
