Name  Wisconsin Card Sorting Test (WCST)-64
Purpose

 The purpose of this test to measure the abstract reasoning ability and the ability to shift cognitive set. WSCT can be considered a measure of executive function, requiring the ability to develop and maintain an appropriate problem solving strategy across changing stimulus conditions in order to achieve a future goal.

Population

 The test is administered on brain injury patients, neurodegenerative disease, or mental illness such as schizophrenia 6.5-89 years of age

Score There are three separate dimensions of this test:

a.       Color

Reliability

Among clinical populations with known or suspected brain dysfunction, these requirements may not be fully met. In such cases, the reliability and validity of the WCST data will depend on the clinical skill and expertise of the examiner.

Validity

Among clinical populations with known or suspected brain dysfunction, these requirements may not be fully met. In such cases, the reliability and validity of the WCST data will depend on the clinical skill and expertise of the examiner.

Norms

 Normative data derived from 899 normal children, adolescents, and adults.

Suggested Uses

 For adults and children the age and education is under consideration.
