Construct Developed in Psychometrics to Determine...

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 individuals 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 individuals 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 ex plain 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 its a measure of intellectual self-esteem. Limited exposure to middle-class cultural tools and low cognitive self-esteem will, undoubtedly, lessen ones 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 feelShow MoreRelatedHow Two Impulsivity Measures Are Used For Human Behavior Exist1982 Words   |  8 Pagesprimary characteristic of impulsivity by its author. This review also explores whether these impulsivity measures are correctly used for the intended purpose. The conclusion suggests further collection of psychometric data for the discussed behavioural measure to further clarify which constructs of impulsivity it intends to measure. Impulsivity is a primary human instinctual behaviour, and yet there is little similarity and agreement in the definition and measurement of the psychologicalRead MoreTherapeutic Psychology2809 Words   |  12 Pagesculture Gradidge and De Jager (2011) evaluated the psychometric properties of the Wellness Questionnaire for Higher Education. The Cronbach’s Alpha coefficients ranged between 0.80 and 0.96 for the seven subscales of the questionnaire and the test-retest coefficients ranged between -0.04 and 0.71 for the seven subscales. Critically evaluate these findings by answering questions 3 and 4. A uniquely indigenous South African measure, the WQHE was developed for the assessment of wellness among higher educationRead MoreThe Construct Of Empathy, By Great Thinkers From Various Disciplines1669 Words   |  7 Pages The construct of empathy attracts the interest of academics from various fields of study, particularly in subfields of psychology. Its function and associated processes in moral development have been discussed for centuries by great thinkers from various disciplines. Hoffman (1982) defines empathy as â€Å"an affective response more appropriate to another’s situation than one’s own†. Nonetheless, the notion of empathy has always been a complex concept, and the lack of uniformity in the usage and understandingRead MoreEssay on The Stanford-Binet Intelligence Scale1012 Words   |  5 Pagesfurther in the 21st century by major corporations who use the Stanford-Binet intelligence scale as a major tool during the hiring process and to determine a person’s IQ. Historical Significance The field of psychology owes the† notion of intelligence to the French psychologist Alfred Binet, who developed the Binet - Simon scale together with his student Theodore Simon in 1904† (Rosati, 2004).

On basis of these components Chu and Choi have divided the procrastinators into active and passive procrastinators. An active procrastinator deliberately decides to delay the work, possesses the ability to deliver it on the deadline but prefers a time pressure, and remains content with the result (Choi Moran, 2009). A passive procrastinator does not want to delay the task but eventually postpones it because of weak decision making and failure toRead MoreRelationship Between Culture and the Clinical Practice of Psychological Assessment8526 Words   |  35 Pagespeople. According to Armour-Thomas and Gopaul-McNicol (1998), tests are not culturally biased because of at least three categories or assumptions: tests are culturally fair and items do not favor a particular cultural group; the tasks assess the cognitive abilities underlying intellectual behavior for all groups; and the tests accurately predict performance for all groups. But there are counter propositions that these ideas differ from.

Test developers must have an understanding of how to develop reliable measures to assess specific constructs while factoring in things like the guidelines of administration to keeping up with necessary revisions and accommodations.
