Intelligence Testing ( Calculate your IQ)

What Is IQ and How It Is Calculated?

IQ (Intelligence Quotient) is the measure of human intelligence expressed by a number resulting from a standardized test, related to chronological age. The vast majority of people are somewhere around 100 (between 90 and 110), with an average intelligence. A value over 120 is considered superior intelligence, and from 130 onwards we are talking about cognitive endowment. Conversely, an IQ of 75-85 expresses a "limiting intellect," while an IQ below 70 shows a delay in cognitive functioning.

Although, according to the recent definition of intelligence, IQ does not only reflect the cognitive dimension of a person's intelligence, its value provides a fairly good prediction of the academic and professional performance of the person being evaluated. Inherited intelligence potential or native intelligence

Every human being is born with a potential for intelligence genetically inherited from his predecessors. It is about native intelligence, also called fluid intelligence. It is measured by non-verbal intelligence tests that involve operating with abstract images and symbols, without the use of verbal concepts.

Activities that require native intelligence:

•  Completing a series of pictures or numbers
• Identifying a pattern (a logical structure) in a set of elements
• Fluid intelligence is fairly stable over time and is perhaps the most important component of total intelligence, making a significant contribution to a person's overall performance.
• Crystallized intelligence although it is generally agreed that human intelligence potential is genetically inherited, the influence of environmental factors is also important, and can either diminish or increase the innate potential. Thus, exposure to a living environment rich in various experiences in early childhood, but also social relationships have a major role in the development of intelligence. Intelligence gained through education, called crystallized intelligence, is measured by intelligence tests that involve operating with different verbal concepts. For example, it measures:
• The richness of a person's vocabulary
• His ability to understand and use words or expressions with a high degree of abstraction
• Ability to make verbal reasoning.
• Understanding and reacting correctly to social situations, of "common sense"

In properly assessing a person's intelligence, both components are important - both non-verbal and verbal intelligence.

How is IQ measured?

Although standardized intelligence tests can measure IQ from the age of approximately 3 years to the age of 90, a complex and valuable assessment of cognitive abilities (both verbal and nonverbal) can be made after the age of Six years. In order to make the right decisions about a child's educational plan, it is very important to evaluate the two major components of intelligence: non-verbal (fluid intelligence, genetically inherited) and verbal (crystallized intelligence, gained through education).
