Make an Upate: Find an example of an intelligence test, and explain how it works. Analyze its strengths and weaknesses as a form of assessment.

A vast majority of the so called intelligence tests found online are not scientifically valid or standardized.

http://www.iq-brain.com/ is a site dedicated to IQ tests. Test results are based on psychometrics, which is a measure of cognitive abilities and reasoning. The tests are based on Cattell, RPM (Raven’s Progressive Matrices) and the Mensa-administered Figure Reasoning Test (FRT).

These tests do not favor individuals with higher education and can thus be classified as being culturally-fair.

Culture-fair also means that tests are completely uninfluenced by any particular culture and there is no gender-bias as well . (https://www.iq-brain.com/about/). This also means the test doesn't rely on general knowledge or fluency in a particular language. It is very difficult to keep these tests absolutely free of any cultural influence. For example, it is said that the Cattell test is not completely free of culture influence.

The IQ-Brain test results are accepted by these societies:

EPL High IQ Society
The Secret High IQ Society (SIQS).
TenIQ high IQ Society
Canadian High IQ Society (CHIQS)

After going through the test, I found that this was mostly testing nonverbal reasoning, simultaneous processing, spatial visualization synthesis, and visual processing. These are hallmarks of the mind's fluid intelligence (Gf).

General Intelligence (G) or cognitive ability can be divided into two types: Fluid Gf and Crystallized intelligence (Gc).

Fluid intelligence or simultaneous processing, is believed to be inborn (the raw processing power of the brain) and Gc is acquired intelligence that happens through acculturation. Verbal and language-based reasoning, know-hows, and concepts arising from long term exposure to general education (formal and informal life experiences) shape the Gc in an individual.

The goal of the test was to find out an individual's fluid reasoning, visual processing, cognitive processing speed, decision-reaction speed and it intentionally ignored other metrics such as verbal, quantitative knowledge or long/short term memory.

The tests are not for children, according to the site, only for adults.
