What is IQ

IQ stands for Intelligence Quotient and is a measure of your reasoning and problem solving abilities. A set of standardized tests exists for which a score of 100 is the average score. If you score above 100, your intelligence is considered higher than average and a score below 100 indicates an intelligence below the average. A complete IQ test includes a structured test with clinical assessments, unlike the many tests available online that may not be completea. Psychologists are not very likely to administer an IQ test just for curiosity.

Why do an IQ test?

What does an IQ test comprise of?

IQ tests are specifically designed to check your memory, both long-term and short-term. It also checks your ability to solve puzzles of increasing complexity as well as how fast a person is able to solve the questions. It therefore measures verbal comprehension, perpetual reasoning, working memory and processing speed. The verbal comprehension portion tests reading, writing and communication abilities. The test questions include picture identification and definition words.

The working memory portion of the test includes questions to test both long-term and short-term memory. It requires the ability to remember and process information as well as sequencing abilities.

The perceptual reasoning part of the test assesses the ability to solve spatial problems. It includes the skills of visual perception and organization. The processing speed part of the test assesses the speed to process and react to information.

IQ tests are good in clinical practice and education but we have to remember that an IQ score does not tell the complete picture. A poor IQ score does not mean the person will not be successful in life and likewise a high IQ score does not take into account how the person will perform under stress, motivation, opportunity etc.
