1. The origins of intelligence tests begin with Alfred Binet who assessed intellectual abilities. He was doing this because a new law in France required French people to go to school. Binet thus put forward the idea of ​​a mental age, a chronological age which most typically corresponds to a given level of performance. This served to separate “boring” children with lower mental ages from “bright” children with higher mental ages. Eventually, Lewis Terman revised Binet's test and produced the widely used Stanford-Binet variant. William Stern calculated the intelligence quotient, which is mental age divided by chronological age multiplied by 100.2. Psychologists do not agree on a single definition of intelligence, but the common similarity between these definitions is that intelligence is the ability to learn from one's abilities, solve problems, and use one's knowledge to s adapt to new situations. To help learn more about the intelligence test, factor analysis is used. It is a statistical procedure that identifies groups of related items and uses them to identify different dimensions of performance that underlie an individual's total score. Spearman believed that everything about intelligence was affected by the ag factor, which is a general intelligence factor that he believed underlies specific mental abilities and is measured by each task on an intelligence test. intelligence. Others believe that intelligence is much more complex and has many specific abilities. This can be more easily seen in people with savant syndrome. They score low on intelligence tests, to the point of being mentally retarded, but they possess an astonishing specific skill that makes them seem like geniuses. Gardener believed that instead of a single intelligence, people have multiple intelligences...... middle of paper ...... this can be attributed to how they stay in school 30% of days more per year than us and also study mathematics outside. from school, when the average American would not. The quality of education plays a major role in the intelligence of an individual, thus demonstrating the importance of environment.11. Psychologists generally consider the SAT to be unbiased. There is no cultural bias because after many attempts, the SAT does not favor one group over another. Intelligence tests can be biased to the extent that if you grew up in a different cultural educational environment, the results will differ from culture to culture. People may perform worse under the pressure of stereotype threat, supporting the fear of being evaluated based on a negative stereotype. Minority students who are told to believe in their potential tend to have better grades and lower dropout rates..
