What did Louis Leon thurstone?

L. L. Thurstone, in full Louis Leon Thurstone, (born May 29, 1887, Chicago, Illinois, U.S.—died September 29, 1955, Chapel Hill, North Carolina), American psychologist who was instrumental in the development of psychometrics, the science that measures mental functions, and who developed statistical techniques for …

How was thurstone’s theory similar to Gardner’s theory?

Thurstone believed that the nine factors he identified, when taken together, make up intelligence. Gardner, on the other hand, proposes that the seven different intelligences are independent of each other. believes that different kinds of intelligence all work together.

What did thurstone and Spearman eventually come to agree on?

Thurstone who argued his own experiments showed that intelligence formed seven primary categories: numerical, reasoning, spatial, perceptual, memory, verbal fluency and verbal comprehension. Thurstone ultimately agreed with Spearman that there was a general factor among ability measures.

What is Spearman’s theory?

Spearman’s two-factor theory proposes that intelligence has two components: general intelligence (“g”) and specific ability (“s”). To explain the differences in performance on different tasks, Spearman hypothesized that the “s” component was specific to a certain aspect of intelligence.

What is Thurstone theory?

Using his new approach to factor analysis, Thurstone found that intelligent behavior does not arise from a general factor, but rather emerges from seven independent factors that he called primary abilities: word fluency, verbal comprehension, spatial visualization, number facility, associative memory, reasoning, and …

What are the 7 primary mental abilities?

The seven primary mental abilities in Thurstone’s model were verbal comprehension, word fluency, number facility, spatial visualization, associative memory, perceptual speed, and reasoning.

What is G in IQ?

The terms IQ, general intelligence, general cognitive ability, general mental ability, and simply intelligence are often used interchangeably to refer to this common core shared by cognitive tests. The g factor targets a particular measure of general intelligence.

What are the 5 primary mental abilities?

Primary Mental Abilities

  • Verbal comprehension.
  • Spatial orientation.
  • Inductive reasoning.
  • Number facility.
  • Word fluency.
  • Associative memory.
  • Perceptual speed.

What does G mean in intelligence?

General intelligence
General intelligence, also known as g factor, refers to the existence of a broad mental capacity that influences performance on cognitive ability measures.

What was the impact of Thurstone’s theory of intelligence?

Thurstone’s contributions to methods of factor analysis have proved invaluable in establishing and verifying later psychometric factor structures, and has influenced the hierarchical models of intelligence in use in intelligence tests such as: WAIS and the modern Stanford-Binet IQ test.

What was Thurstone’s contribution to psychometric factor analysis?

Thurstone’s contributions to methods of factor analysis have proved invaluable in establishing and verifying later psychometric factor structures, and has influenced the hierarchical models of intelligence in use in intelligence tests such as WAIS and the modern Stanford-Binet IQ test.

How many mental abilities are there in Thurston’s theory?

It is also the basis for many contemporary group tests of intelligence. Thurstone (1938) analyzed the data from 56 different tests of mental abilities and concluded that to the extent that there is a general factor of intelligence, it is unimportant and possibly epiphenomenal. From this point of view there are seven primary mental abilities:
