Charles Spearman was an English psychologist who is best known for his work on intelligence and statistical methods. He is credited with the development of the concept of "general intelligence," also known as the g factor.
Spearman's work on intelligence began in the late 19th century, when he was studying the performance of soldiers in the British army. He noticed that some soldiers seemed to excel in all areas of training, while others struggled in multiple areas. This led him to believe that there might be a general factor that underlies all intellectual abilities, which he referred to as the g factor.
To test this hypothesis, Spearman conducted a series of statistical analyses on data from intelligence tests. He found that there was a strong correlation between scores on different tests, suggesting that there was indeed a general factor that influenced performance across a variety of tasks. This g factor was later identified as being closely related to cognitive abilities such as problem-solving, critical thinking, and abstract reasoning.
Spearman's work on the g factor had a significant impact on the field of psychology, and it remains a central concept in the study of intelligence. However, it has also been the subject of controversy, with some researchers arguing that it oversimplifies the complexity of intelligence and fails to account for cultural and environmental influences on cognitive abilities.
Despite these criticisms, Spearman's concept of general intelligence continues to be an important theoretical framework for understanding the nature of intellectual abilities. It has contributed to our understanding of how intelligence is related to other psychological constructs such as personality and motivation, and it has informed the development of modern intelligence tests and educational interventions.
In conclusion, Charles Spearman's concept of general intelligence has had a lasting impact on the field of psychology and continues to be a valuable tool for understanding the nature of intellectual abilities.
Charles Spearman and his two
Using factor analysis, Spearman was able to prove the theory of general intelligence. The truth is that this theory laid the foundations for a whole new study approach. The Pearson Correlation was named for its inventor, another British academic, Karl Pearson. Do some internet research and write two to three paragraphs on what you find. It was designed to show whether one aspect of human ability was related to another by mathematically plotting the results from one test against the results of another test. The former term comes from the Latin root "educere" — which means to "draw out" and thus refers to the ability to make meaning out of confusion.
This means anyone who can perform well on one test should be able to perform well on other tests because of their generalized intelligence. There is also evidence for specific intelligences s , which are measures of specific skills in narrow domains, including creativity and practical intelligence. If a child did well in one subject, they generally also did well in another subject, and vice versa. Cattell felt that general intelligence is in fact split into two further groups, fluid and crystallized. Fighting for perceived glory on the battlefield was not enough for Charles Spearman. Conversely, you may feel more aligned with Gardner's theory of multiple intelligences because you feel that you have high intellectual ability in some areas and low intellectual ability in others. S stands for specific knowledge.
Charles Spearman's Theory of Intelligence Explained
Statistical Analysis and Tests of Mental Variables When Spearman became involved, the psychological testing movement was already underway. Although modern-day psychologists do not all agree on his theories, he is revered for being one of the earliest pioneer psychologists while working with ''The Father of Psychology'' Wilhelm Wundt at his laboratory in Germany. What physiological correlates of intelligence can you find in your research? Today intelligence is usually understood as a hierarchy: smaller factors manifest in the ability to do highly specific tasks, but those factors can be arranged into broader intermediary categories which in turn are encompassed within the most general factor, g. However, Charles Spearman was skeptical and invented his Spearman Rank Order Correlation statistical technique to replace Pearson's technique. He claimed that g was not made up of one single ability, but rather two genetically influenced, unique abilities working together. When psychologists attempted to correlate the results of these tests to one another, they didn't have much luck. This theory has been tested and found wanting by Roberts et al.
. Spearman was able to show that Pearson's statistic greatly underestimated the strength of relationships between the results of two tests. The Spearman g factor is something an individual is born with and those with higher amounts may be predisposed to succeed in their careers. Intelligence testing measuring the g factor has been studied recently to re-explore Spearman's law of diminishing returns. The g factor measures intelligence but does not include the five senses, physical skills, and human memory processes. He also spoke of a neural phenomenon g. Charles Spearman attended the University of Leipzig, which is one of the oldest universities in the world Charles Spearman's Personal Life Charles Spearman married a woman named Fanny Aikman on September 4, 1901.
Spearman felt that though g could be detected in any sufficiently-broad set of cognitive measures, he felt that the tests from which his g had emerged "had no place in schools" because they "deflected" teachers', pupils', parents' and politicians' attention from the business of education which, as the Latin root of the word implies, should be concerned with "drawing out" whatever talents a student may have. More specifically, SLDR predicts that the the g factor will account for a smaller proportion of individual differences in cognitive tests scores at higher scores on the g factor. He called these abilities "eductive" and "reproductive". Spearman wanted to learn more about psychophysiology, or how the mind interacts with the body. We have different types of intelligence that we recognize today, but it was Charles Spearman who brought science into the study of intelligence. What is your personal opinion of intelligence? American Journal of Psychology. It can serve as an alternative to a high school education requirement.
Retrieved 27 November 2022. Therefore Spearman and others have regarded g as the perhaps genetically determined real essence of intelligence. To fix that problem, Spearman invented a new statistical technique that became known as the Spearman Rank Order Correlation. 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. It is a guide or a reference tool to help people consider their options. Spearman began to wonder if there was something wrong with the methods his colleagues were using to determine whether relationships existed or not.
The g factor is still frequently studied in current research. Psychology: Ninth Edition in Modules. Research on differences in g between ethnic groups see race and intelligence has often sparked public controversy. Research shows that although g factor differently, it has been found that it is affected if influenced early in life, rather than adulthood where there is little to no impact. Charles Spearman's Biography Charles Spearman is known for being an experimental psychologist who studied theories related to intelligence. Another esteemed thinker by the name of Karl Pearson invented the Pearson Product Moment Correlation.
Spearman Theory of Intelligence and What It Reveals
His many published papers cover a wide field, but he is especially distinguished by his pioneer work in the application of mathematical methods to the analysis of the human mind, and his original studies of correlation in this sphere. Reaction time correlates strongly with g, while movement time correlates less strongly. Some research has found the g completely mediates the relation between IQ and cortical thickness. For thousands of years before Spearman, intellectuals and philosophers worked to understand the concept. While g is robustly observed in Western populations, it is questionable whether g is manifested in cognitive data from other cultural groups. Some psychometricians regard g as a statistical artifact.
If so, you might ask, 'Does evidence of intellectual ability increase as overall health increases? Both he and his opponents are agreed that there are Specific Factors peculiar to individual tests, both he and his opponents agree that there are Group Factors which run through some but not all tests. It would take him 9 years to earn his PhD, having been recalled to the military to serve in the Second Boer War. G means a particular quantity derived from statistical operations. His studies provided a great deal of information and ideas for those who came after him. When Spearman went back through the data, he noticed that people who did well in one area of the factor analysis test would also score higher in all other areas as well compared to those who did not perform well in one area. For somebut not alltheorists, g is defined as general intelligence. Most of these g-loaded tests typically involve some form of abstract reasoning.
Charles Spearman: Theory of Intelligence & Overview
Intelligence was often considered to be a philosophical concept. Charles Edward Spearman was born on September 10, 1863, in London, England. However, his critics have responded that we think of something like athletic skill as just that — a skill and not strictly intelligence. What is an example of analytical intelligence? Intelligence has always been an important component in the study of psychology. Spearman then would plot the results in a manner similar to Pearson to see the correlation, or lack of correlation, on graphs.
