Spearman's hypothesis and the arguments that invoke it have received multiple criticisms, including criticisms of Jensen's method of correlated vectors, of the inference that the first formulation of Spearman's hypothesis supports the second, and of genetic and biological arguments made on the basis of Spearman's hypothesis.
Spearman's two-factor theory proposes that intelligence has two components: general intelligence ("g") and specific ability ("s"). [7] To explain the differences in performance on different tasks, Spearman hypothesized that the "s" component was specific to a certain aspect of intelligence.
Chief amongst these achievements was the discovery of the general factor in human intelligence, [4] and his subsequent development of a theory of "g" [8] and synthesis of empirical work on ability. [9] Spearman was strongly influenced by the work of Francis Galton.
More specifically, the theory does not explain the influence of parental nurture and social interactions on human development. Domain-specific learning is a theory in developmental psychology that says the development of one set of skills is independent from the development of other types of skills.
The g Factor was reviewed favorably by Canadian psychologist J. Philippe Rushton, who called it "an awesome and monumental exposition of the case for the reality of g." [3] Robert Sternberg was more critical in his review, writing that "there is a great deal of evidence of various kinds that the general factor does not do what Jensen claims."
The PASS theory provides the theoretical framework for a measurement instrument called the Das-Naglieri Cognitive Assessment System (CAS), published in 1997. [6] This test, now in a Second Edition (CAS2; 2014, Naglieri, Das & Gold-stein) is designed to provide an assessment of intellectual functioning redefined as four brain-based cognitive processes (Planning, Attention, Simultaneous and ...
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.
Spearman appears first in this formula before Brown because he is a more prestigious scholar than Brown. [16] For example, Spearman established the first theory of reliability [15] and is called "the father of classical reliability theory." [17] This is an example of Matthew Effect or Stigler's law of eponymy.
