James McKeen Cattell was a pioneering psychologist who made significant contributions to the field of psychology, particularly in the areas of intelligence testing and the study of individual differences. His theory of intelligence, which he referred to as the "measurement of mental ability," was based on the belief that intelligence is a general mental ability that can be measured and quantified.
Cattell's theory of intelligence was based on his research on the relationship between mental ability and various measures of cognitive performance. He believed that mental ability was a product of both inherited and environmental factors, and that it could be measured through a variety of cognitive tasks and tests. Cattell's theory was influential in the development of the concept of "g," or general intelligence, which refers to the general mental ability that underlies specific cognitive abilities.
Cattell also made significant contributions to the study of individual differences in intelligence and personality. He believed that individual differences were largely due to inherited differences in mental ability, and that these differences could be measured through the use of standardized tests. Cattell's work on individual differences laid the foundation for the study of personality and intelligence, and his contributions to the field continue to be recognized and influential today.
In addition to his work on intelligence and individual differences, Cattell was also interested in the measurement of psychological traits and abilities. He developed a number of tests and techniques for measuring psychological traits, including his famous "16 Personality Factors" test, which is still widely used today.
Overall, James McKeen Cattell's theory of intelligence and his contributions to the study of individual differences have had a lasting impact on the field of psychology and continue to be influential in the study of intelligence and personality.
Human Intelligence: James McKeen Cattell
Administered through the James McKeen Cattell Fund at Duke University, these awards unique from the Here are the receivers of the 2022— 2023 James McKeen Cattell Fund Fellowship: Kenneth Bollen Kenneth Bollen University of North Carolina APS Fellow Kenneth Bollen is the H. We have no zero point from which we can measure psychological merit. German physiologist Hermann von Helmholtz 1821—1894 measured the speed of the neural impulses and explored the physiology of hearing and vision. But the brain changes which are excited from within are less likely to result in motor discharges than those which form parts of sensori-motor area. Incidentally, Cattell's father was both.
The corporation was one of the largest creators and administrators of mental tests. If the range of ability is the same in each science and if the difficulty of assigning the order in each science is the same, then the figures in the lower third of the table should tend to be the same in the different sciences. Typical but extreme cases are the epileptic fit — a violent explosion followed by coma — or mania followed by dementia. Psychology is a required subject in the undergraduate curriculum. The increase in the size of the probable errors is irregular, it being more difficult to assign a position to some men than to others. When he became aware of Galton's anthropometric laboratory, he began to correspond with him, and designed a series of 50 psychophysical tests based on Galton's earlier work.
Brock University is not responsible for its content. This, indeed, I regard as the most important result of this paper, as science is advanced chiefly by the extension of quantitative methods, and it might not have been foreseen that it would be possible to measure degrees of scientific merit. As a man falls asleep, he becomes passive, 581 he does not look or listen, and gradually his imagery becomes visions and dreams. At the time of his doctoral dissertation, Wissler was one of Cattell's graduate students at Columbia University. The organic sensations give us no knowledge of the extra-bodily world and but little of what happens within the body, but the hedonic elements are constant may be intense. Even though Cattell's tests were later proven ineffective, he helped to lay the groundwork for further study in intelligence testing.
Four Scholars Pursue Diverse Research Through Cattell Sabbatical Awards
It is possible that it requires more ability to be an astronomer than to be a psychologist, and it is equally possible that, in view of the larger endowments, longer history and more conventional problems, less ability will suffice for the astronomer. Lesson Summary James McKeen Cattell was a scientist and psychologist who helped to legitimize the field of psychology, which was once viewed as being akin to philosophy and phrenology. The grade of the astronomer who stands third is 4. By testing for knowledge, memory, and other individual factors, psychologists sought a formula that could determine how well a given individual's mental processes worked. Our reactions as a rule work and are useful, giving rise to new perceptions and new reactions, which also work, and thus the material world becomes real for us.

Is it possible to determine, by some concrete method, how intelligent an individual is? This view was somewhat controversial, especially in light of the dissertation research of Cattell's use of statistical methods and quantification of data helped in the development of American psychology as an experimental science. In the case of the emotions the cerebral commotion, as James has so brilliantly argued, is probably chiefly due to the excitation of bodily changes id the object and the discharges to the brain from the bodily excitation. Lloyd Gordon Ward retired , who is responsible for its content. A perception may, as a rule. It is only a mad cat that may jump at an imaginary mouse, and for it the jumped-at mouse becomes real.
In savage rites and religious manias we have these in a crude form. Senator for New Jersey. Description A Brief History of Modern Psychology offers a concise account of the evolution of this dynamic field—from early pioneers of psychological theory to cutting-edge contemporary applications. In 1896 Albert von Schrenck-Notzing stated that pretrial coverage regarding court cases Albert von Schrenck-Notzing clouds the minds of witnesses memories due to their inability to separate their own original accounts with the press reports. This experience is, however, such that it leads us to live in the world of common sense and perhaps later in the world of natural science. Even research studies are much more tough. Today forensic scientists are brought to court in order to aid the jury and judge in their final verdicts.
When the actual physical stimulus is explained to observers, some of them see it as before, others quite differently. If some one speaks to me, I am in the habit of answering ; if I imagine the voice, I do not answer audibly if at all. American Journal of Psychology, 14, 310-328. Will open in new window. This is especially true of the body known by kinesthetic and organic sensations ; the seen body, which alters its relation to the visual world, is more likely to be regarded as part of it. How forensic psychology began and flourished.
. Our own future work and that of others must proceed in two directions. We are told that physiologically considered the whole neural mechanism is a machine for converting stimuli into reactions, and one of the most original applications of the fact that objects excite bodily changes by preorganized mechanism is made in the explanation of the emotions, I venture to take this occasion to propose a thesis, which in certain aspects is analogous to the James theory of the emotions. I know that in the retinal image two of the angles are acute and two are obtuse, but I hesitate and make a geometrical construction before I know which is which. Progress here will be blocked until there are psychologists who are mathematicians or mathematicians who are psychologists. What can we learn from the tests of elementary traits regarding the higher intellectual and emotional life? Experiments of my own, which I described several years ago, give a somewhat striking demonstration of the extent to which perceptions are shaped by the requirements of motor response. In the first and second groups are included one tenth of those in each science, and in the remaining groups one fifth.
