Psychological tests are standardized assessments designed to measure various aspects of a person's mental functions, behaviors, and personality traits. These tests can help psychologists and other professionals understand an individual's cognitive abilities, emotional state, and social skills. Common types of psychological tests include intelligence tests, personality assessments, and neuropsychological evaluations. The results from psychological tests can be used for various purposes, such as diagnosing mental health conditions, guiding treatment plans, or assessing an individual's suitability for a job. They are typically administered in a controlled environment and analyzed using established scoring systems to ensure reliability and validity.
