What is the neurobiological basis of Spearman general factor of intelligence?

What are the main factors in Spearman’s theory of intelligence?

He proposed that intelligence consists of two factors, i.e., the ”g” factor (general ability) and the ”s” factor (specific ability), where the ”g” factor is involved in every general mental ability task of the person, and the ”s” factor is responsible for only the specific intellectual abilities of the person.

What is the neurobiology of intelligence?

Neuroscience and intelligence refers to the various neurological factors that are partly responsible for the variation of intelligence within species or between different species. A large amount of research in this area has been focused on the neural basis of human intelligence.

What is the g factor in general intelligence?

The g factor (also known as general intelligence, general mental ability or general intelligence factor) is a construct developed in psychometric investigations of cognitive abilities and human intelligence.

What is the g factor according to Spearman?

The g-factor theory or general factor theory states that intelligence is composed of general intelligence. The g factor refers to the broad spectrum of mental faculties that influences the performance on a wide variety of cognitive abilities.

What is intelligence according to Thorndike?

Thorndike defines intelligence as “one’s capacity to deal effectively with situations”. For Jean Piaget, ‘intelligence is the ability to adapt to one’s surroundings’.

What is Sternberg’s theory of intelligence which includes creative analytical and practical intelligences?

Triarchic Theory of Intelligence Key Takeaways

Sternberg, contends that there are three types of intelligence: practical (the ability to get along in different contexts), creative (the ability to come up with new ideas), and analytical (the ability to evaluate information and solve problems).

Does brain size correlate with intelligence?

In healthy volunteers, total brain volume weakly correlates with intelligence, with a correlation value between 0.3 and 0.4 out of a possible 1.0. In other words, brain size accounts for between 9 and 16 percent of the overall variability in general intelligence.

Does head circumference correlate with intelligence?

scale and verbal IQ scores at 8 years of age and current head circumference. Full-scale IQ increased an average of 1.27 points (95% CI: 0.08–2.47 points) and verbal IQ increased an average of 1.45 points (95% CI: 0.21–2.69 points) for each 1-SD increase in current head circum- ference, after multivariate adjustment.

What is the correlation between brain size and intelligence quizlet?

Recent studies indicate some correlation (about +. 40) between brain size and intelligence. As brain size decreases with age, scores on verbal intelligence tests also decrease.

Who told about the general and specific factor of intelligence?

Charles Spearman

Charles Spearman proposed this theory in the year 1923. According to his theory, intelligence consists of two factors: ‘g’ and ‘s’, where ‘g’ stands for generalized factor and ‘s’ stands for the specific factor.

When did Spearman proposed two factor theory of intelligence?


The English psychologist, Charles Spearman (1863-1945), in 1904 proposed his theory of intelligence called two-factor theory. According to him intellectual abilities are comprised of two factors, namely; the general ability known as G-factor and specific Abilities known as S-factors.

What factors contribute to generalized intelligence?

The five factors being tested are knowledge, quantitative reasoning, visual-spatial processing, working memory, and fluid reasoning [1]. Wechsler Adult Intelligence Scale (WAIS) is a test designed to measure intelligence in adults and older adolescents.

What did Charles Spearman believe about intelligence?

British psychologist Charles Spearman believed intelligence consisted of one general factor, called g, which could be measured and compared among individuals. Spearman focused on the commonalities among various intellectual abilities and deemphasized what made each unique.

How does Spearman’s general intelligence apply to school experiences?

Using statistical factor analysis Spearman identified g, a single underlying intelligence factor he believed accounted for the variety of observable abilities. Spearman noticed that children’s grades across all school subjects tended to be highly correlated.

What is the difference between general and specific intelligence?

Psychologists believe that there is a construct, known as general intelligence (g), that accounts for the overall differences in intelligence among people. There is also evidence for specific intelligences (s), which are measures of specific skills in narrow domains, including creativity and practical intelligence.

What is the theory of general intelligence?

The Theory of General Intelligence proposes that there is only one intelligence, measured by a single ‘g factor’ that underlies performance in all cognitive domains. Performance in different cognitive tasks are interrelated, all hinging on the single ‘g factor’.

What is the difference between general intelligence and multiple intelligences?

The general intelligence proponents believe that there is one factor from which all intelligence is derived; the multiple intelligences proponents believe that there are different kinds of intelligence.

The General Intelligence and Reasoning section contains 25% weightage of the SSC CGL Tier-I 2022 Exam. Around 66% of the section is covered by Verbal Reasoning and 34% is about Non-Verbal Reasoning.

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.

What did Charles Spearman suggest around the turn of the 20th century?

Spearman, in full Charles Edward Spearman, (born September 10, 1863, London, England—died September 17, 1945, London), British psychologist who theorized that a general factor of intelligence, g, is present in varying degrees in different human abilities.

How many types of general intelligence are there?

Research has proposed two types of general intelligence. Crystallized-type intelligence is acquired knowledge, such as vocabulary or mathematics. Fluid-type intelligence is the ability to solve unfamiliar visual and verbal reasoning problems.
