Category Test (CT)

The Category Test (CT) is a psychological assessment tool used to evaluate an individual’s cognitive flexibility and abstract reasoning abilities. It is often used in neuropsychological testing and research to assess brain dysfunction or cognitive impairments.

Objective of the Test

The objective of the Category Test is to measure an individual’s ability to categorize and shift their cognitive focus efficiently. It assesses their capacity to flexibly switch between different categories, adapt to changing rules, and apply abstract reasoning skills in problem-solving tasks.

Test Administration

The Category Test usually involves presenting the participant with a series of stimuli, such as images, shapes, or words, that can be classified into different categories based on specific rules. The individual is then required to sort the stimuli into appropriate categories, demonstrating their cognitive flexibility and ability to recognize abstract concepts.

Interpreting the Results

The results of the Category Test provide valuable insights into an individual’s cognitive abilities and potential cognitive impairments. A thorough analysis of the participant’s categorization patterns, response times, and error rates helps identify deficits in cognitive flexibility, concept formation, and problem-solving strategies.

Applications of the Category Test

The Category Test is widely used in clinical neuropsychology, educational psychology, and cognitive research. It assists in diagnosing conditions such as brain injuries, attention-deficit/hyperactivity disorder (ADHD), learning disabilities, and age-related cognitive decline. The CT also helps evaluate the effectiveness of interventions or treatments aiming to improve cognitive functioning.
