Query: Who developed the first IQ measurement?
Lewis Terman, developer of the Stanford–Binet Intelligence Scales, based his English-language Stanford–Binet IQ test on the French-language Binet–Simon test developed by Alfred Binet. Terman believed his test measured the "general intelligence" construct advocated by Charles Spearman (1904). Terman differed from Binet in reporting scores on his test in the form of intelligence quotient ("mental age" divided by chronological age) scores after the 1912 suggestion of German psychologist William Stern. Terman chose the category names for score levels on the Stanford–Binet test. When he first chose classification for score levels, he relied partly on the usage of earlier authors who wrote, before the existence of IQ tests, on topics such as individuals unable to care for themselves in independent adult life. Terman's first version of the Stanford–Binet was based on norming samples that included only white, American-born subjects, mostly from California, Nevada, and Oregon.
In 1939, David Wechsler realized the limitation of the Stanford-Binet and designed an intellect by tapping a diverse sample of capabilities. In earlier methods of assessment, Weschler devised the format that we currently known as the Wechsler scales, consisting of a collection of subsets. He believed in the unitary nature of intelligence but subscribed to the idea that intellect can be best measured through interdependent, qualitatively different abilities. Historical, the picture arrangement subsets of the Wechsler scales have been characterized repeatedly as being nonverbal and verbal measure of social competence. For this reason, clinicians interpret performance on the picture arrangement subsets as measures of social ability.
Although picture arrangement (PA) has been viewed as predictive of social intelligence, there has been considerable difficulty defining social intelligence, social functioning and/or social competence. Wechsler believed that general intelligence could be applied to all situations. Thus, “social” intelligence might best be conceptualized as one aspect of general intelligence.
However, the term became widely known with the publication of Goleman's book: "Emotional Intelligence – Why it can matter more than IQ" (1995). It is to this book's best-selling status that the term can attribute its popularity. Goleman has followed up with several further popular publications of a similar theme that reinforce use of the term.
To date, tests measuring EI have not replaced IQ tests as a standard metric of intelligence. Emotional Intelligence has also received criticism on its role in leadership and business success.
Following the Army Alpha and Army Beta tests for soldiers in World War I, mental testing became popular in the US, where it was soon applied to school children. The federally created National Intelligence Test was administered to 7 million children in the 1920s, and in 1926 the College Entrance Examination Board created the Scholastic Aptitude Test to standardize college admissions. The results of intelligence tests were used to argue for segregated schools and economic functions—i.e. the preferential training of Black Americans for manual labor. These practices were criticized by black intellectuals such a Horace Mann Bond and Allison Davis. Eugenicists used mental testing to justify and organize compulsory sterilization of individuals classified as mentally retarded. In the United States, tens of thousands of men and women were sterilized. Setting a precedent which has never been overturned, the U.S. Supreme Court affirmed the constitutionality of this practice in the 1907 case "Buck v. Bell".
Modern "Psychological evaluation" has been around for roughly 200 years, with roots that stem as far back as 2200 B.C. It started in China, and many psychologists throughout Europe worked to develop methods of testing into the 1900s. The first tests focused on aptitude. Eventually scientists tried to gauge mental processes in patients with brain damage, then children with special needs.
Some psychologists have recently pointed out that previous instruments used to measure openness actually assessed two distinctive aspects. The first is intellect, which reflects intellectual engagement and perceived intelligence and is marked by ideas, while the second is emotion, which reflects the artistic and contemplative qualities related to being engaged in sensation and perception and is marked by fantasy, aesthetics, feelings and actions. On this basis, intellect was found to be associated with the neural system of the working memory, which is related to "g", whereas openness was not. In addition, according to a study of genetic behaviour, intellect is genetically closer to intelligence than openness.
Emotional Intelligence: Why It Can Matter More Than IQ is a 1995 book by Daniel Goleman. In this book, Goleman posits that emotional intelligence is as important as IQ for success, including in academic, professional, social, and interpersonal aspects of one's life. Goleman says that emotional intelligence is a skill that can be taught and cultivated, and outlines methods for incorporating emotional skills training in school curricula.
Psychology was a branch of the domain of philosophy until the 1870s, when it developed as an independent scientific discipline in Germany and the United States. Psychology as a self-conscious field of experimental study began in 1879, in Leipzig Germany, when Wilhelm Wundt founded the first laboratory dedicated exclusively to psychological research in Germany. Wundt was also the first person to refer to himself as "a psychologist". Other important early contributors to the field include Hermann Ebbinghaus (a pioneer in the study of memory), William James (the American father of pragmatism), and Ivan Pavlov (who developed the procedures associated with classical conditioning).
Sternberg was born on December 8, 1949, to a Jewish family, in New Jersey. Sternberg suffered from test anxiety as a child. As a result, he became an inadequate test taker. This upset him and he reasoned that a test was not an adequate measurement of his true knowledge and academic abilities. When he later retook a test in a room that consisted of younger students, he felt more comfortable and his scores increased dramatically. The following year, he created the Sternberg Test of Mental Ability (STOMA), his first intelligence test. This problem of test taking is what sparked Sternberg's interest in psychology.
Wilhelm Maximilian Wundt (; ; 16 August 1832 – 31 August 1920) was a German physician, physiologist, philosopher, and professor, known today as one of the founding figures of modern psychology. Wundt, who noted psychology as a science apart from philosophy and biology, was the first person ever to call himself a psychologist. He is widely regarded as the "father of experimental psychology". In 1879, Wundt founded the first formal laboratory for psychological research at the University of Leipzig. This marked psychology as an independent field of study. By creating this laboratory he was able to establish psychology as a separate science from other disciplines. He also formed the first academic journal for psychological research, "Philosophische Studien" (from 1881 to 1902), set up to publish the Institute's research.
The history of mind-wandering research dates back to 18th century England. British philosophers struggled to determine whether mind-wandering occurred in the mind or if an outside source caused it. In 1921, Varendonck published "The Psychology of Day-Dreams", in which he traced his "'trains of thoughts' to identify their origins, most often irrelevant external influences". Wallas (1926) considered mind-wandering as an important aspect of his second stage of creative thought – incubation. It wasn't until the 1960s that the first documented studies were conducted on mind-wandering. John Antrobus and Jerome Singer developed a questionnaire and discussed the experience of mind-wandering. This questionnaire, known as the Imaginal Processes Inventory (IPI), provides a trait measure of mind-wandering and it assesses the experience on three dimensions: how vivid the person's thoughts are, how many of those thoughts are guilt- or fear-based, and how deep into the thought a person goes. As technology continues to develop, psychologists are starting to use functional magnetic resonance imaging to observe mind-wandering in the brain and reduce psychologists' reliance on verbal reports.
Ernst Heinrich Weber (24 June 1795 – 26 January 1878) was a German physician who is considered one of the founders of experimental psychology. He was an influential and important figure in the areas of physiology and psychology during his lifetime and beyond. His studies on sensation and touch, along with his emphasis on good experimental techniques gave way to new directions and areas of study for future psychologists, physiologists, and anatomists.
IQ and educational attainment are strongly correlated (estimates range form .40 to over .60.) There is controversy, however, as to whether education affects intelligence – it may be both a dependent and independent variable with regard to IQ. A study by Ceci illustrates the numerous ways in which education can affect intelligence. It was found that; IQ decreases during summer breaks from schooling, children with delayed school entry have lower IQ's, those who drop out of education earlier have lower IQ's and children of the same age but of one years less schooling have lower IQ scores. Thus it is difficult to unravel the interconnected relationship of IQ and education where both seem to affect one another.
Now discredited, eugenic beliefs played a small role at the hospital. Dr. Henry H. Goddard established an intelligence testing program on Ellis Island during 1913. Doctors would use metal calipers to measure the circumference of immigrants’ heads, and immigrants of “superior racial stock” were often favored when entering the United States. Additionally, many immigrants were detained at Ellis Island for mental illness and placed in the hospital's psychiatric ward. Some of the contemporary clinical classifications for mental illness are now archaic: idiot, imbecile, moron, or feeble-minded. It is likely that many of these immigrants were not actually mentally ill, but that cultural differences and a language barrier, as well as the immigrants’ anxiety about a new country, made them appear mentally ill. More objective testing methods were developed by Dr. Howard Andrew Knox to determine with increased accuracy whether an emigrant was mentally deficient. The Knox tests were effective in that they did not require specific cultural knowledge for successful performance. The Daughters of the American Revolution provided a robust occupational therapy program for immigrants detained at Ellis Island. They also worked with U. S. servicemen, merchant seamen, and members of the U.S. Coast Guard. Some were suffering from shell shock.
In 1714 Dutch scientist and inventor Daniel Gabriel Fahrenheit invented the first reliable thermometer, using mercury instead of alcohol and water mixtures. In 1724 he proposed a temperature scale which now (slightly adjusted) bears his name. He could do this because he manufactured thermometers, using mercury (which has a high coefficient of expansion) for the first time and the quality of his production could provide a finer scale and greater reproducibility, leading to its general adoption. In 1742, Anders Celsius (1701–1744) proposed a scale with zero at the boiling point and 100 degrees at the freezing point of water, though the scale which now bears his name has them the other way around. French entomologist René Antoine Ferchault de Réaumur invented an alcohol thermometer and temperature scale in 1730 that ultimately proved to be less reliable than Fahrenheit's mercury thermometer.
Standardized testing has been a part of American education since the 1800s, but the widespread reliance on standardized is largely a 20th-century phenomenon. For instance the College Entrance Examination Board did not begin standardized testing in connection to higher education until 1900. The College Entrance Examination Board was established and in 1901, the first examinations were administered around the country in nine subjects. This test was implemented with the idea of creating standardized admissions for the United States in northeastern elite universities. Originally, the test was also meant for top boarding school in order to standardize curriculum. With origins in World War I the Army Alpha and Beta tests developed by Robert Yerkes and colleagues. Before then, immigration in the mid-19th century contributed to the growth of standardized tests in the United States. Standardized tests were used in immigration when people first came over to test social roles and find social power and status.
The variables studied were "intelligibility" and "fidelity". Intelligibility was a measure of how "understandable" the sentence was, and was measured on a scale of 1–9. Fidelity was a measure of how much information the translated sentence retained compared to the original, and was measured on a scale of 0–9. Each point on the scale was associated with a textual description. For example, 3 on the intelligibility scale was described as "Generally unintelligible; it tends to read like nonsense but, with a considerable amount of reflection and study, one can at least hypothesize the idea intended by the sentence".
Abstract algebra was developed in the 19th century, deriving from the interest in solving equations, initially focusing on what is now called Galois theory, and on constructibility issues. George Peacock was the founder of axiomatic thinking in arithmetic and algebra. Augustus De Morgan discovered relation algebra in his "Syllabus of a Proposed System of Logic". Josiah Willard Gibbs developed an algebra of vectors in three-dimensional space, and Arthur Cayley developed an algebra of matrices (this is a noncommutative algebra).
The terms were coined in 1954 by linguist Kenneth Pike, who argued that the tools developed for describing linguistic behaviors could be adapted to the description of any human social behavior. As Pike noted, social scientists have long debated whether their knowledge is objective or subjective. Pike's innovation was to turn away from an epistemological debate, and turn instead to a methodological solution. "Emic" and "etic" are derived from the linguistic terms phonemic and phonetic respectively, which are in turn derived from Greek roots. The possibility of a truly objective description was discounted by Pike himself in his original work; he proposed the emic/etic dichotomy in anthropology as a way around philosophic issues about the very nature of objectivity.
A second committee was formed and headed by Nicholas Hobbs. This 8-member committee was responsible for the creation of the first document. The committee used contributions from over 2,000 psychologists to create the first principles. The committee reviewed the situations submitted by psychologists to the first committee and attempted to organize the situations into themes. Themes that emerged reflected many of the political and social issues of the time including racial segregation, post-war politics, and the testing industry. The first version of the Ethical Standards of Psychologists was adopted in 1952 and published in 1953 by the American Psychological Association (APA). The document was over 170 pages in length. The first version contained many ethical dilemmas that psychologists had written about and submitted to the first committee as case examples.
The term "cognitive science" was coined by Christopher Longuet-Higgins in his 1973 commentary on the Lighthill report, which concerned the then-current state of Artificial Intelligence research. In the same decade, the journal "Cognitive Science" and the Cognitive Science Society were founded. The founding meeting of the Cognitive Science Society was held at the University of California, San Diego in 1979, which resulted in cognitive science becoming an internationally visible enterprise. In 1972, Hampshire College started the first undergraduate education program in Cognitive Science, led by Neil Stillings. In 1982, with assistance from Professor Stillings, Vassar College became the first institution in the world to grant an undergraduate degree in Cognitive Science. In 1986, the first Cognitive Science Department in the world was founded at the University of California, San Diego.
The Wechsler intelligence scales were originally developed from earlier intelligence scales by David Wechsler. The first Wechsler test published was the Wechsler–Bellevue Scale in 1939. The Wechsler IQ tests for children and for adults are the most frequently used individual IQ tests in the English-speaking world and in their translated versions are perhaps the most widely used IQ tests worldwide. The Wechsler tests have long been regarded as the "gold standard" in IQ testing. The Wechsler Adult Intelligence Scale—Fourth Edition (WAIS–IV) was published in 2008 by The Psychological Corporation. The Wechsler Intelligence Scale for Children—Fifth Edition (WISC–V) was published in 2014 by The Psychological Corporation, and the Wechsler Preschool and Primary Scale of Intelligence—Fourth Edition (WPPSI–IV) was published in 2012 by The Psychological Corporation. Like all current IQ tests, the Wechsler tests report a "deviation IQ" as the standard score for the full-scale IQ, with the norming sample median raw score defined as IQ 100 and a score one standard deviation higher defined as IQ 115 (and one deviation lower defined as IQ 85).
In the 2002 book "IQ and the Wealth of Nations", and "IQ and Global Inequality" in 2006, Richard Lynn and Tatu Vanhanen created estimates of average IQs for 113 nations. They estimated IQs of 79 other nations based on neighboring nations or by other methods. They also created an estimate of "quality of human conditions" for each nation based on gross national product per capita, adult literacy rate, fraction of the population to enroll in secondary education, life expectancy, and rate of democratization. Lynn and Vanhanen found a substantial correlation between the national IQ scores they created and these various socioeconomic factors. They conclude that national IQ influences these measures of well-being, and that national differences in IQ are heavily influenced by genetics, although they also allow for some environmental contributions to it. They regard nutrition as the most important environmental factor, and education a secondary factor.
David Wechsler, developer of the Wechsler–Bellevue Scale of 1939 (which was later developed into the Wechsler Adult Intelligence Scale) popularized the use of "deviation IQs" as standard scores of IQ tests rather than the "quotient IQs" ("mental age" divided by "chronological age") then used for the Stanford–Binet test. He devoted a whole chapter in his book "The Measurement of Adult Intelligence" to the topic of IQ classification and proposed different category names from those used by Lewis Terman. Wechsler also criticized the practice of earlier authors who published IQ classification tables without specifying which IQ test was used to obtain the scores reported in the tables.
Frances Galton established the first tests in London for measuring IQ. He tested thousands of people, examining their physical characteristics as a basis for his results and many of the records remain today. James Cattell studied with him, and eventually worked on his own with brass instruments for evaluation. His studies led to his paper "Mental Tests and Measurements" ,one of the most famous writings on psychological evaluation. He also coined the term ""mental test"" in this paper.
