Charles Spearman was a British psychologist who is known for his contributions to the field of intelligence and psychological testing. His most famous theory is known as the Two Factor Theory of Intelligence, which proposed that intelligence is composed of two distinct factors: a general factor (g) and specific factors (s).
According to Spearman's theory, the general factor (g) represents a person's overall intelligence, which is thought to be related to cognitive abilities such as problem-solving, critical thinking, and abstract reasoning. This general factor is thought to be highly correlated with a person's overall intelligence, and it is believed to be influenced by both genetic and environmental factors.
The specific factors (s), on the other hand, represent more narrow abilities that are specific to certain tasks or domains. For example, someone may have a specific ability for math, but not for language. These specific abilities are thought to be less correlated with overall intelligence than the general factor, and are believed to be more influenced by environmental factors.
Spearman's Two Factor Theory has been influential in the field of psychology, and it has been used to explain a wide range of phenomena related to intelligence and cognitive abilities. However, the theory has also been criticized for its lack of empirical support and its oversimplification of the complex nature of intelligence.
Despite these criticisms, Spearman's Two Factor Theory remains an important contribution to our understanding of intelligence and cognitive abilities. It has helped to shape the way that intelligence is measured and has provided a framework for further research in this area.
Charles Spearman Biography & Theory
Imagination, Cognition and Personality, 9 3 , 185-211. Among them, we find mechanical, verbal, numerical, and spatial activities. However, the scores of tests of cognitive ability do in fact produce a primary factor, g. The schools should organize various academics and sports activities to improve the specific abilities of the students. Spearman wanted to bring the scientific method to intelligence. THEORIES OF INTELLIGENCE INTRODUCTION Throughout history, numerous researchers have suggested different definitions regarding intelligence and that it is a single, general ability, while other researchers believed that the definition of intelligence includes a range of skills. Gardner 1983, 1987 initially proposed Gardner holds that most activities such as dancing will involve a combination of these multiple intelligences such as spatial and bodily-kinesthetic intelligences.
Above Image: WISC-IV Sample Test Question The Wechsler Adult Intelligence Scale WAIS , is an IQ test designed to measure cognitive ability in adults and older adolescents, including verbal comprehension, perceptual reasoning, working memory, and processing speed. In any collections of IQ tests, by definition the test that best measures g is the one that has the highest correlations with all the others. All the knowledge, skills, experiences, skills an individual has acquired throughout his or her life is called fluid intelligence, and the ability to correctly understand and utilize the information or knowledge, and learning new skills, is called fluid intelligence. The Binet-Simon scale of 1905 comprised 30 items designed to measure judgment, comprehension, and reasoning which Binet deemed the key characteristics of intelligence. In other words, there was a strong correlation between performing well in math and music, and Spearman then attributed this relationship to a central factor, that of general intelligence g. The most common approach has been to divide individuals into multiple ability groups using an observable proxy for their general intellectual ability, and then to either compare the average interrelation among the subtests across the different groups, or to compare the proportion of variation accounted for by a single common factor, in the different groups.
I feel that that definition is very specific and does not even cover a decent range of people. He proposed that intelligence consists of two factors, i. Peter Schönemann has also argued for the non-existence of g. This led Spearman to the conclusion that would lead to the theory of intelligence: that there must be one central factor that influences the cognitive abilities of each individual. E This eliminates bias in administering the test. The s factor is not something an individual is born with, but rather is acquired through experience as well as the environment. There is some debate about whether g represents a real thing or is just a sort of statistical average of test results.
As a result, he and his colleague, Theodore Simon, began to develop a specific set of questions that focused on areas such as memory and problem-solving skills. According to the American Psychological Association, a hierarchy of factors with g at its apex and group factors at successively lower levels is now the most widely accepted model of cognitive ability. Ne mund të përcaktojmë llojin e operacioneve mendore në të cilat ai luan një rol dominues në krahasim me faktorin tjetër ose specifik. Score from 110 to 119 are considered to be High Average. Spearman affirmed in 1923, with his bifactorial theory of intelligence, that the academic performance of some school-age children correlated with the results they obtained in some sensory tests that he himself chose and applied to them.
Charles Spearman's Theory of Intelligence Explained
Through observation and measurement, the theory of intelligence was born. Handbook of psychology, 21-45. However, the S factor refers to the more specific abilities that the individuals use to complete the different tasks. Analytical intelligence, also referred to as componential intelligence, refers to intelligence that is applied to analyze or evaluate problems and arrive at solutions. Towards an understanding of the Kiganda concept of intelligence.
He developed a model in which all variations in intelligence test scores are explained by two factors: first, a factor specific to an individual mental task: the individual abilities that would make a person more skilled at a specific cognitive task; and second a general factor g that governs performance on all cognitive tasks. The Abilities of Man: Their Nature and Measurement. Among them is Charles Spearman. What is your personal opinion of intelligence? Charles Spearman created the Spearman Rank Order Correlation statistical method to replace Pearson's method because sometimes Pearson's technique would underestimate the correlation that existed between two given variables. The performance by the person is decided by the G-factor and the S-factors. Later on Spearman propagated Three Factor Theory. If your mental age is equal to your chronological age, you will have an IQ of 100, or average.
A related study has reported that the correlation between brain size reported to have a heritability of 0. New England Journal of Medicine, 367 20 , 1921-1929. Michael Phelps would probably destroy Usain Bolt in swimming, just like Bolt would destroy Phelps in racing. Annals Of Dyslexia, 37, 19-35 Gignac, G. The G factor refers to the general cognitive abilities that are measured in individuals when completing different tasks. Controversy over whether the seven specific types of intelligences are actually intelligences or whether they are abilities such as musical, body-kinesthetic, interpersonal and intrapersonal.
Yet both are incredibly dominant in their specialization and that dominance would make them better than the average person taken from the street because they are more athletic than a person selected at random. Intelligence was often considered to be a philosophical concept. It would take him 9 years to earn his PhD, having been recalled to the military to serve in the Second Boer War. Which of the following psychologists would agree with this statement? Since then, Binet, Simon and Terman have all contributed to intelligence testing. According to Meunier 2003 , when adults are able to learn from their lives from multiple intelligence models, they are able to find liberation in inspecting potentials which were never developed or highlighted.
Fluid intelligence also refers to all the knowledge, skills, experiences, and talents that a person has learned over his or her life. Human Ability, Macmillan, London. Programs for self-development from hobbies, programs and courses can mainly re-integrate the native intelligences of an individual in a way that can be satisfying from personal perspective. What is notable about this observation is that a person cannot be trained to have a higher G-factor. For example, Tucker-Drob 2009 found that a general factor accounted for approximately 75% of the variation in seven different cognitive abilities among very low IQ adults, but only accounted for approximately 30% of the variation in the abilities among very high IQ adults. The total intelligence of the person is the sum total of the G-factor and the S-factors.

Thorndike: The International Examinations Inquiry Meetings 1931-1938": Correction to Deary, Lawn, and Bartholomew 2008 " PDF. They reported that for subtests of both the WAIS and the WISC, subtest intercorrelations decreased monotonically with ability group, ranging from approximately an average intercorrelation of. In drawing, it may be due to G+S3 and in social sciences; it may be due to G+S4 and so on. Spearman tried to find the ratio between 'g' and 'S' factor on the basis of his longitudinal studies. C It will be higher than the IQs of children who stay in disadvantaged settings only if adoptive parents have above-average IQs.
