Assessment of Intellectual Functioning

Psychological testing -- also known as the psychological assessment -- is basically the foundation of how psychologists are able to get a better understanding a person and their behavior. It is a process of problem solving for many professionals -- to try and regulate the core components of a person's psychological or mental health difficulties, personality, IQ, or some other element. It is likewise some kind of process that aids and identifies not just flaws of a person, but also all of their strengths. Psychological testing are done to measure a person's performance at a particular point in time. Psychologists discuss about an individual's "present functioning" in expressions of their test data (Gonzalez-Gordon, & Romero, 2012). In order to fully investigate the history of intellectual assessment, this paper will talk about key historical figures and numerous theories and approaches of testing intelligence. The drive of intelligence testing is to get a better understanding regarding to the evolution of cognitive aptitudes in humans as compared to others in a provided population. As a result psychological tests are not able to predict future or distinctive potential. With that said, this paper will talk about assessment of Intellectual Functioning with a focus on Wechsler Adult Intelligence Scale and Stanford -- Binet Intelligence Scales.

Brief History

The study of cognitive abilities and intelligence go all the way back like centuries and is characterized by the worst and the best of science -- scholarly discussions and bitter rivalries, breakthroughs in research and academic deception, major assessment model shifts, and the birth of a commercial industry that produces hundreds of millions of dollars in yearly income. The assessment of intelligence began a long time ago in the BC period as time went by the development of intelligence testing had gone up and some are well respected (Arrigo, 2009). Intelligence tests are measures designed to assess the level of cognitive capabilities of an individual compared to other people in a population (Turk & Barber, 2004). Even though the different psychologist had different standpoint in regards to measure intelligence, they all made some kind of impact on intelligence testing in their era. Still dealing with unresolved issues going all the way back from its birth, the study of intelligence has seen as numerous bare periods in its growth as it has seen steps onward.

Your IQ

A person's IQ -- intellectual quotient -- is a theoretic concept of a measure of general intelligence. It is important to note that IQ tests do not actually measure actual intelligence -- they measure what we believe could be important parts of intelligence.

There are two primary type measures which are being utilized to test an individual's intellectual functions -- neuropsychological assessment and intelligence tests. Intelligence tests are the more usual kind administered and contain the Stanford-Binet and the Wechsler scales (Maeda, & Takeuchi, 2012). Neuropsychological assessments -- which can take up to about 2 days to direct -- is a far more broad form of evaluation. It is concentrated not just on testing for intelligence, but then again likewise on figuring out all of the cognitive strong point and deficits of the individual. Research shows that Neuropsychological assessment is most typically done with individuals who have suffered some sort of brain damage, dysfunction or some type of organic brain issue, just as having a brain hemorrhage (Gonzalez-Gordon,, 2012).

Wechsler Adult Intelligence Scale

In 1997 The Psychological Business introduced the newest form of their adult intelligence test, The Wechsler Adult Intelligence Scale-III (WAIS-III) (Arrigo, 2009). This instrument was first brought on the scene in 1939 and is at the time the most extensively utilized test of adult intelligence. The most ordinarily managed IQ test is called the Wechsler Adult Intelligence Scale -- Fourth Edition (WAIS-IV). It in general takes anyplace from an hour to an hour and a half to manage, and is suitable for any person aged 16 or even older to take. (Children can be given an IQ test particularly made for them which is called the Wechsler Intelligence Scale for Children -- Fourth Edition, or the WISC-IV.) (Emerson, Einfeld, & Stancliffe, 2010)

The WAIS-IV is basically apportioned into four major scales to attain at what is named a "full scale IQ." Every one of the scales are further divided into a number of optional and mandatory (also called supplemental) subtests. The mandatory subtests are essential to arrive at an individual's entire scale IQ. The supplemental subtests are what provide more valuable data in regards to a person's cognitive abilities.

Stanford -- Binet Intelligence Scales

The development of the Stanford -- Binet Intelligence Scales introduced the current field of intelligence analysis and was one of the first samples of an adaptive test. The test started in France, and then was brushed up a bit in the United States. However, the Stanford -- Binet test began with the French psychologist Alfred Binet, whom the government of France appointed with creating a method of identifying knowledgeably challenged children for their assignment in special education programs (Suwalska, Lojko, Janik, Palys, & Rybakowski, 2008). As Binet specified, case studies may be more helpful and detailed, but the time necessary to test numerous individuals would be extreme. In 1917, at Stanford University, Lewis Terman, the psychologist released an adjusted examination which became recognized as the "Stanford -- Binet test" (Williams, 2010).

Analysis of Wechsler Adult Intelligence and Stanford -- Binet Intelligence

Currently, in its third revision, the Wechsler Adult Intelligence Scale-III has a new factor type of structure. The theoretical construction of the new instrument is considered to be hierarchical in nature and also includes four first-order factors with a second-order factor located at the apex (Maeda, Kita, Miyawaki, & Takeuchi, 2012). Furthermore to the theoretical hierarchical factor structure of the new instrument, there is an understood factor structure that is utilized for scoring. This assumed format includes a Verbal IQ Index, Performance IQ Index Full and a Scale IQ Index. Experts show that there have been many studies that have investigated the construct validity of both the explicit and implied theoretical format of the instrument. The results show the WAIS-III gives an excellent evaluation of the four factor model and a general factor (Obi, Braun, Baio, & Drews-Botsch, 2011). A lot of the times, the data, on the other hand, did not upkeep the construct legitimacy of a Verbal IQ Index/Performance IQ Index dichotomy. These conclusions and practical inferences for the clinician utilizing the tool are talked about.

The simple format of the new tool is very comparable to the Wechsler Adult Intelligence Scale-Revised and its forerunner the Wechsler Adult Intelligence Scale (Arrigo, 2009). The issue format of WAIS-III is likewise similar to editions that were an earlier version. One vital feature of the new tool is the existence of a clear and understood first-order factor arrangement. The tool's explicit factor structure is hierarchical in description and encloses a second-order general factor at the apex and broad first-order factors (Weber, 2009). The four broad first-order factors are recognized as processes of perceptual organization verbal comprehension, processing speed and working memory. The inclusion additional broad first-order influences is more constant with modern theories of intelligence (Turk, Das, Howlin, & Barber, 2004)

When it comes to Stanford -- Binet Intelligence Scales they consist of 15 subtests, which are all grouped into the four area scores. Not every one of the subtests is given to each age group; but then again six subtests are managed to all age levels. The research shows that these subtests are: Comprehension, Pattern Analysis, Vocabulary, Bead Memory, Quantitative, and Memory for Sentences (Reichenberg, Weiser, & Rabinowitz, 2002). The amount of tests given and general test difficulty is altered based on the age of the test taker and performance on the sub-test that determines word knowledge. The subtest evaluating word knowledge is provided to all test takers and is the first subtest given to students.

The following is an analysis of the detailed cognitive abilities that the four area scores are measuring. The Verbal Reasoning part score measures understanding and verbal knowledge gotten from the school and home learning situation and imitates the capability to put on verbal skills to new circumstances (Arrigo, 2009). Examples of subtests including this factor measure skills which consist of: social judgment, awareness, word knowledge, and ability to separate the unsuitable feature in visual material and social intelligence, and the capacity to distinguish essential from non-essential aspect.
