The g factor, or "general factor", is a construct developed in psychometrics to determine cognitive abilities. It is a variable that summarizes positive correlations among various cognitive tasks, which demonstrate an individual's performance at one type of cognitive task tends to be comparable to his or her performance at other kinds of cognitive tasks. The g factor typically accounts for 40 to 50 percent of the variance in IQ test performance, and IQ scores are frequently regarded as estimates of an individual's g factor rating (Kamphaus et al. 2005). The terms IQ, general intelligence, general cognitive ability, general mental ability, or simply intelligence, are often used interchangeably to refer to the common core shared by …show more content…
These include the Wason selection task, computerized games governed by difficult rules, pragmatic reasoning schemes, analogical reasoning tasks, class-inclusion, scientific reasoning tasks, and categorization tasks. These factors explain why non-verbal tests are often referred to as culture-free, and almost necessary for easing assimilation.
Acquiring relevant background knowledge - which will be closely associated with social class - is important in psychometric tests, in addition to non-cognitive sources. Jensen seems to be unaware or at least avoid potential stressful effects relating to negative social evaluation and systematic prejudice, which many children experience every day. Superficial factors like dialect, facial appearance, and self-presentation all play major roles. These have significant effects on the way we see and evaluate ourselves. Bandura et al (1996) have shown how limited confidence in cognitive-based tests acquired by parents are inherited by their children, resulting in fear and apathy in many intellectual tasks. Here, g is not a general ability variable, rather it's a measure of intellectual self-esteem.
Limited exposure to middle-class cultural tools and low cognitive self-esteem will, undoubtedly, lessen one's self-confidence, and cause anxiety in testing situations. There is a well-known association between IQ test performance and test-anxiety. In his meta-analysis of 562 studies, Hembree (1988) found that subjects who feel
