Measuring Intelligence: Principles of test construction
Intelligence is how one of the many ways that individuals are different. One person may have the ability to understand more complex ideas than another. The first principle of test construction is age difference. Some who are older could be more wiser, but that is not always the case. Principle number two is general mental ability. Which measures only the general product of the various and distinct elements of the intelligence. The intellectual terms range from idiot, imbecile, and Moron.
The nature of intelligence: Cross cultural studies
psychologists do not agree about the basic nature of intelligence. They cannot decide whether it is a single, or general ability. The theories of intelligence involved controversy over the definition of the word. It is indecisive whether your intelligence should be measured by how high you score on your IQ test, or if it should be more broad. Charles Spearman believed it was a common factor or general mental capacity, and is at the core of different mental abilities. Louis L. Thurstone disagreed and concluded that there were seven different "primary mental abilities" . Such as verbal comprehension, numerical ability, reasoning, and perceptual speed. He thought it was more important to look at an individuals specific pattern of mental abilities.
Overall I have learned that intelligence is a the use of mental images and concepts, problem solving and decision making, and the use of language Most people just call it "book smarts" but there is far more to it than that.
