Three Stratum Theory
The three-stratum theory is a theory of cognitive ability proposed by the American psychologist John Carroll in 1993.J. B. Carroll (1997), "The three-stratum theory of cognitive abilities" in D. P. Flanagan, J. L. Genshaft et al., ''Contemporary intellectual assessment: Theories, tests, and issues'', Guilford Press, New York, NY, USA, pp. 122-130. It is based on a factor-analytic study of the correlation of individual-difference variables from data such as psychological tests, school marks and competence ratings from more than 460 datasets. These analyses suggested a three-layered model where each layer accounts for the variations in the correlations within the previous layer. The three layers (strata) are defined as representing narrow, broad, and general cognitive ability. The factors describe stable and observable differences among individuals in the performance of tasks. Carroll argues further that they are not mere artifacts of a mathematical process, but likely reflect ph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cognition
Cognition refers to "the mental action or process of acquiring knowledge and understanding through thought, experience, and the senses". It encompasses all aspects of intellectual functions and processes such as: perception, attention, thought, intelligence, the formation of knowledge, memory and working memory, judgment and evaluation, reasoning and computation, problem solving and decision making, comprehension and production of language. Imagination is also a cognitive process, it is considered as such because it involves thinking about possibilities. Cognitive processes use existing knowledge and discover new knowledge. Cognitive processes are analyzed from different perspectives within different contexts, notably in the fields of linguistics, musicology, anesthesia, neuroscience, psychiatry, psychology, education, philosophy, anthropology, biology, systemics, logic, and computer science. These and other approaches to the analysis of cognition (such as embodied ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psychologist
A psychologist is a professional who practices psychology and studies mental states, perceptual Perception () is the organization, identification, and interpretation of sensory information in order to represent and understand the presented information or environment. All perception involves signals that go through the nervous syste ..., cognitive, emotional, and social processes and behavior. Their work often involves the experimentation, observation, and interpretation of how individuals relate to each other and to their environments. Psychologists usually acquire a bachelor's degree in psychology, followed by a master's degree or doctorate in psychology. Unlike psychiatrist, psychiatric physicians and psychiatric nurse-practitioners, psychologists usually cannot prescribe medication, but depending on the jurisdiction, some psychologists with additional training can be licensed to prescribe medications; qualification requirements may be different from a bachelor's d ...

John Bissell Carroll
John Bissell Carroll (June 5, 1916 – July 1, 2003) was an American psychologist known for his contributions to psychology, linguistics and psychometrics.Stansfield, Charles W. “Carroll, John Bissell.” ''Concise Encyclopedia of Educational Linguistics''. Ed. B. Spolsky. Amsterdam; New York: Elsevier, 1999. Early years Carroll was born in Hartford, Connecticut. Early in his life, Carroll became interested in music and language. His interest in language was further sparked by becoming friends with Benjamin Lee Whorf at the age of thirteen and discussing Whorf's ideas about a close connection between culture and language. Carroll also helped to edit and publish Whorf's ''Language, Thought and Reality'' in 1956. Education Carroll studied at Wesleyan University, majoring in Classics and graduating summa cum laude in 1937. He attended the University of Minnesota to earn a doctoral degree in Psychology. At the University of Minnesota, Carroll began studying under B. F. Ski ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Factor Analysis
Factor analysis is a statistical method used to describe variability among observed, correlated variables in terms of a potentially lower number of unobserved variables called factors. For example, it is possible that variations in six observed variables mainly reflect the variations in two unobserved (underlying) variables. Factor analysis searches for such joint variations in response to unobserved latent variables. The observed variables are modelled as linear combinations of the potential factors plus " error" terms, hence factor analysis can be thought of as a special case of errors-in-variables models. Simply put, the factor loading of a variable quantifies the extent to which the variable is related to a given factor. A common rationale behind factor analytic methods is that the information gained about the interdependencies between observed variables can be used later to reduce the set of variables in a dataset. Factor analysis is commonly used in psychometrics, perso ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Correlation
In statistics, correlation or dependence is any statistical relationship, whether causal or not, between two random variables or bivariate data. Although in the broadest sense, "correlation" may indicate any type of association, in statistics it usually refers to the degree to which a pair of variables are ''linearly'' related. Familiar examples of dependent phenomena include the correlation between the height of parents and their offspring, and the correlation between the price of a good and the quantity the consumers are willing to purchase, as it is depicted in the so-called demand curve. Correlations are useful because they can indicate a predictive relationship that can be exploited in practice. For example, an electrical utility may produce less power on a mild day based on the correlation between electricity demand and weather. In this example, there is a causal relationship, because extreme weather causes people to use more electricity for heating or cooling. Howev ...

Differential Psychology
Differential psychology studies the ways in which individuals differ in their behavior and the processes that underlie it. This is a discipline that develops classifications (taxonomies) of psychological individual differences. This is distinguished from other aspects of psychology in that although psychology is ostensibly a study of individuals, modern psychologists often study groups, or attempt to discover general psychological processes that apply to all individuals. This particular area of psychology was first named and still retains the name of "differential psychology" by William Stern in his book (1900). While prominent psychologists, including Stern, have been widely credited for the concept of individual differences, historical records show that it was Charles Darwin (1859) who first spurred the scientific interest in the study of individual differences. His interest was further pursued by his half-cousin Francis Galton in his attempt to quantify individual differences ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
G Factor (psychometrics)
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. It is a variable that summarizes positive correlations among different cognitive tasks, reflecting the fact that an individual's performance on one type of cognitive task tends to be comparable to that person's performance on other kinds of cognitive tasks. The ''g'' factor typically accounts for 40 to 50 percent of the between-individual performance differences on a given cognitive test, and composite scores ("IQ scores") based on many tests are frequently regarded as estimates of individuals' standing on the ''g'' factor.Kamphaus et al. 2005 The terms '' IQ, general intelligence, general cognitive ability, general mental ability'', and simply ''intelligence'' are often used interchangeably to refer to this common core shared by cognitive tests.Deary et al. 2010 Howeve ...

Cattell–Horn–Carroll Theory
The Cattell–Horn–Carroll theory (commonly abbreviated to CHC), is a psychological theory on the structure of human cognitive abilities. Based on the work of three psychologists, Raymond B. Cattell, John L. Horn and John B. Carroll, the Cattell–Horn–Carroll theory is regarded as an important theory in the study of human intelligence. Based on a large body of research, spanning over 70 years, Carroll's Three Stratum theory was developed using the psychometric approach, the objective measurement of individual differences in abilities, and the application of factor analysis, a statistical technique which uncovers relationships between variables and the underlying structure of concepts such as 'intelligence' (Keith & Reynolds, 2010). The psychometric approach has consistently facilitated the development of reliable and valid measurement tools and continues to dominate the field of intelligence research (Neisser, 1996). The Cattell–Horn–Carroll theory is an integration of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
G-VPR Model
The g-VPR model is a model of human intelligence published in 2005 by psychology professors Wendy Johnson and Thomas J. Bouchard Jr. (Johnson & Bouchard, 2005) They developed the model by analyzing Gf-Gc theory, John Carroll’s Three-stratum theory and Vernon’s verbal-perceptual model. The g-VPR model is a four stratum model: # First stratum: Primary traits. # Second stratum: Broader than stratum I, but still narrow abilities. # Third stratum: Verbal, perceptual and rotation factors. # Fourth stratum: g factor. Why Johnson and Bouchard claim the g-VPR model is better Johnson and Bouchard made comparisons between Gf-Gc, three-stratum and verbal-spatial model. They found that Vernon's verbal-perceptual model got better modeling-fit results than the other two, but still did not fit very well. Then, based on the verbal-spatial model, Johnson and Bouchard "began by adding a memory factor (labeled content memory to distinguish it from the memory factor in the fluid-crystallized ...
