neuropsychological assessment designed to assess cognitive flexibility and conceptual thinking. This test includes a series of tasks in which the participant must classify a set of objects according to common characteristics or features. The test usually includes both verbal and non-verbal components that require the person to identify and group objects or concepts that have certain attributes. The categorization test in the booklet is often used to assess executive functions such as containment, switching, and conceptualization, and helps identify deficits in cognitive processing, especially in conditions such as dementia, traumatic brain injury, or psychiatric disorders. This test is useful for distinguishing between types of cognitive impairment and is often used in clinical practice and scientific research.
