His research not only led him to develop the concept of the g factor of general intelligence, but also the s factor of specific intellectual abilities. [2] L. Thurstone , Howard Gardner , and Robert Sternberg also researched the structure of intelligence, and in analyzing their data, concluded that a single underlying factor was influencing the ...
Intelligence testing has long been an important branch of quantitative psychology. The nineteenth-century English statistician Francis Galton, a pioneer in psychometrics, was the first to create a standardized test of intelligence, and he was among the first to apply statistical methods to the study of human differences and their inheritance.
For example, a logarithm of base 2 8 = 256 will produce a measurement in bytes per symbol, and a logarithm of base 10 will produce a measurement in decimal digits (or hartleys) per symbol. Intuitively, the entropy H X of a discrete random variable X is a measure of the amount of uncertainty associated with the value of X when only its ...
The g factor [a] 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 assertion 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.
Intelligence analysis is the application of individual and collective cognitive methods to weigh data and test hypotheses within a secret socio-cultural context. [1] The descriptions are drawn from what may only be available in the form of deliberately deceptive information; the analyst must correlate the similarities among deceptions and extract a common truth.
An intelligence quotient (IQ) is a total score derived from a set of standardized tests or subtests designed to assess human intelligence. [1] Originally, IQ was a score obtained by dividing a person's mental age score, obtained by administering an intelligence test, by the person's chronological age, both expressed in terms of years and months.
While empirical research often supports a general intelligence factor (g-factor), [5] Gardner contends that his model offers a more nuanced understanding of human cognitive abilities. [6] This difference in defining and interpreting "intelligence" has fueled ongoing discussions about the theory's scientific robustness.
Thorndike (1920) described social intelligence as the ability to understand others and "act wisely in human relations". He proposed that social intelligence was itself an aspect of a person's IQ. More recent authors within the intelligence literature have also attempted to define social intelligence but have not succeeded in clarifying the ...
