Quick Answer: What did Arthur Jensen believe?

Jensen claimed, on the basis of his research, that general cognitive ability is essentially an inherited trait, determined predominantly by genetic factors rather than by environmental conditions.

What is Jensen theory?

The Jensen’s measure, or Jensen’s alpha, is a risk-adjusted performance measure that represents the average return on a portfolio or investment, above or below that predicted by the capital asset pricing model (CAPM), given the portfolio’s or investment’s beta and the average market return.

Who is Arthur Jensen in psychology?

Arthur R. Jensen, an educational psychologist who ignited an international firestorm with a 1969 article suggesting that the gap in intelligence-test scores between black and white students might be rooted in genetic differences between the races, died on Oct. 22 at his home in Kelseyville, Calif. He was 89.

What did Arthur Jensen believe?

Dr. Jensen asserted that IQ tests were valid measures of intelligence that did not discriminate against blacks or other minorities. This was the subject of his 1980 book, “Bias in Mental Testing,” which Flynn called a classic in the field of psychological measurement.

How does Arthur Jensen explain concept of intelligence?

Arthur Jensen proposed a hierarchical model of intelligence consisting of abilities operating at two levels, called Level I and Level II. Level I is the associative learning in which output is more or less similar to the input (e.g., rote learning and memory).

What is thurstone’s theory of intelligence?

Louis Leon Thurstone proposed theory in 1930’s that intelligence is composed of several different factors. 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 did Arthur Jensen conclude about intelligence based on his research?

Jensen concluded from his research that Level I abilities are equally-distributed among the races, whereas white and Asian students demonstrate advantages in tests of Level II abilities.

What is the most controversial conclusion made by Arthur Jensen?

Jensen’s most controversial conclusion was that Level II intelligence is prevalent among Asians, then Caucasians, then African Americans. Robert Williams was among those who called out racial bias in Jensen’s results (Williams, 1970).

What is Spearman’s theory of intelligence?

Spearman’s two-factor theory proposes that intelligence has two components: general intelligence (“g”) and specific ability (“s”). He claimed that g was not made up of one single ability, but rather two genetically influenced, unique abilities working together. He called these abilities “eductive” and “reproductive”.

What are intelligence theories?

The theories are grouped into four major theory types: (1) psychometric theories; (2) cognitive theories; (3) cognitive-contextual theories; and (4) biological theories. Cognitive-contextual theories emphasize processes that demonstrate intelligence within a particular context (such as a cultural environment).

Who developed the IQ test most widely used today?

The most widely used intelligence tests include the Stanford-Binet Intelligence Scale and the Wechsler scales. The Stanford-Binet is the American adaptation of the original French Binet-Simon intelligence test; it was first introduced in 1916 by Lewis Terman, a psychologist at Stanford University.

How does the Triarchic theory help us to understand intelligence?

According to Sternberg, intelligence is an ability to adapt, to shape and select environment to accomplish ones goals and those of ones society and culture. This theory attempts to understand the cognitive processes involved in problem solving.

What is sampling theory of intelligence?

Theory of Intelligence # 3. Sampling Theory of Godfrey Thomson: Thomson’s theory is known as the sampling theory. According to the sampling theory, every test samples a certain range of the elementary human abilities; some with a wide range, some with a narrow range.

Who gave the theory of intelligence?

Charles Spearman, an English psychologist, established the two-factor theory of intelligence back in 1904 (Spearman, 1904). To arrive at this theory, Spearman used a technique known as factor analysis.
