Purpose: IQ tests are designed to assess various cognitive abilities including problem-solving, logical reasoning, pattern recognition, and memory. They are often used for educational placements, evaluating intellectual disabilities or giftedness, and in research studies to understand cognitive strengths and weaknesses.
Limitations: While IQ tests can provide insights into certain aspects of cognitive function, they do not measure creativity, emotional intelligence, practical skills, or social intelligence. Cultural, socioeconomic, and educational factors can influence performance, and factors like test anxiety or unfamiliarity with the test format can also affect the results. Thus, IQ scores should be interpreted as one component of a broader assessment of an individual's abilities.
