The WAIS-IV is a widely used and well-established intelligence test. When administered and interpreted correctly, it provides valuable insights into an individual's cognitive abilities. However, it is essential to consider the test's limitations and potential biases when using it in various settings.

, ranging from 40 to 160 [12, 15]. These subtests are grouped into four index scores: Verbal Comprehension Index (VCI): Measures the ability to listen to a question, draw upon learned information, and reason through a response [11, 17]. Subtests include Vocabulary, Similarities, and Information [14]. Perceptual Reasoning Index (PRI): Evaluates non-verbal and fluid reasoning [11]. It includes Visual Puzzles, Figure Weights, Matrix Reasoning, and Block Design [11, 14]. Working Memory Index (WMI): Assesses the capacity to retain and manipulate information in short-term memory [11, 17]. Key tasks include Digit Span and Arithmetic [14]. Processing Speed Index (PSI): Measures the speed and accuracy of visual identification and decision-making [11, 17]. It uses subtests like Symbol Search and Coding [14]. Clinical Utility and Applications Beyond just measuring "IQ," the WAIS-IV is a vital diagnostic tool in several fields: ADHD & Learning Disabilities: Research often shows that individuals with ADHD may score significantly lower (on average 5–9 points) on working memory and processing speed compared to their verbal or fluid reasoning. Neuropsychological Evaluation: It is frequently used in comprehensive batteries alongside tools like the
