What is IQ?

Intelligence Quotient (IQ) is a score that represents a person's cognitive abilities compared to others of the same age. IQ scores have been linked to educational attainment, job performance, and personal income. Research has shown that IQ is a strong predictor of success in education and work.

What is an IQ Test?

IQ tests are standardized tests designed to measure cognitive abilities, focusing on various related skills and attributes, such as visual perception, abstract reasoning, pattern recognition, spatial orientation, and analytical thinking. The first IQ test was developed by French psychologist Alfred Binet in 1905, designed to measure a child's intelligence and compare it to what their intelligence "should be," related to their actual age. Since then, several individually administered IQ tests have been developed and updated. Researchers consider IQ tests to be among the most accurate and reliable of all psychological tests and assessments.

What do IQ Tests Measure?

IQ tests measure an individual's learning capacity and ability to solve complex problems of analytical nature. The CAI's cognitive assessment plan measures five distinct aspects of human intelligence - visual perception, abstract reasoning, pattern recognition, spatial orientation, and analytical thinking.

How is IQ Assessed?

IQ tests consist of a set of questions designed to measure various cognitive abilities, and the results are compared to a standardized population. Normalizing means that the average IQ score is 100, and scores above or below this indicate above-average or below-average intelligence, respectively. IQ scores follow a normal distribution of statistical data, and approximately 95% of the world's population has scores within two standard deviations of the mean. The CAI's cognitive assessment tools compare results to peers of the same age group, providing a normalized score that indicates where an individual stands compared to others of their age.

Can IQ Increase?

Recent research indicates that cognitive training can improve intelligence, suggesting that an individual's IQ score can change. The humanbrain's plasticity allows for new synapses to form and for cognitive skills to be improved through practice. The CAI's cognitive assessment tools can identify an individual's cognitive strengths and weaknesses, providing insights on areas to improve and potentially increase IQ scores.
