When did Spearman measure general intelligence?
1904
Spearman’s attempt to establish general, fundamental laws of psychology was based on his statistical work in determining correlations among mental abilities, reflected in his classic paper, “ ‘General Intelligence,’ Objectively Determined and Measured” (1904).
What is a measure of general intelligence?
The intelligence quotient (IQ) is a measure of intelligence that is adjusted for age. The Wechsler Adult lntelligence Scale (WAIS) is the most widely used IQ test for adults. Brain volume, speed of neural transmission, and working memory capacity are related to IQ.
What did Charles Spearman do?
Charles Edward Spearman (September 10, 1863 – September 7, 1945) was an English psychologist known for work in statistics, as a pioneer of factor analysis, and for Spearman’s rank correlation coefficient. He also did seminal work on human intelligence, including the discovery of the g factor.
What did Spearman do psychology?
Charles Spearman was well known as the pioneer of factor analysis as a statistical technique to reduce and interpret data. He was the first psychologist who used the application of mathematical models for analyzing and interpreting the complexities present in human mind.
What did David Wechsler develop?
He developed the Wechsler-Bellevue Intelligence Scale, which quickly became the most widely used adult intelligence test in the United States.
What is an example of general intelligence?
For example, researchers might find that people who score well on questions that measure vocabulary also perform better on questions related to reading comprehension. In 1904, he suggested that this g factor was responsible for overall performance on mental ability tests.
