Theories of Intelligence
What is intelligence? There are plenty of theories out there, yet psychologists still do not agree on a standard definition of intelligence. Some thinkers have suggested that intelligence can be viewed as a general mental ability while others propose that there are actually different types of intelligence.
Learn more in this overview of some of the best-known theories of intelligence.
Factors That Impact Intelligence
Is intelligence a product of genetics, experience or the interaction of both? Psychologists not only disagree about exactly what constitutes intelligence, they also continue to disagree about the various factors that influence an individual's intelligence.
Today, most agree that nature and nurture both have an impact, but the degree to which genetics and environment influence intelligence remains a matter of considerable debate. Learn more about some of the major influences on intelligence.
The Development of Intelligence Tests
The measurement of intelligence has been a controversial subject ever since psychologist Alfred Binet developed the first formal IQ test. Today, many modern intelligence tests are still based upon Binet's original assessment. In addition to debating how to measure intelligence, concerns are also centered on exactly how these results are put to use. Learn more in this overview of the history of intelligence testing.
Fluid and Crystallized Intelligence
Psychologist Raymond Cattell suggested that there are two different types of intelligence: fluid intelligence and crystallized intelligence. Learn more about the differences between fluid and crystallized intelligence .
Multiple Intelligences
