A mental ability test to establish categories and switch concepts.
Designed to examine the ability of adults with brain injury or psychiatric illness to establish categories and switch conceptual sets.
The test uses plastic utensils that can be sorted according to size, color and utensil type. The test emphasizes qualitative aspects of performance and is based on dynamic interactional principles of testing. Detailed and systematic guidelines for facilitating performance through the use of cues are provided. The extent to which performance can be modified with cues provides information that can be directly used to choose and design an intervention program. The test has been piloted with people with brain injury and schizophrenia, ages 18 to 86. It is easy to transport and can be administered at bedside in 15 to 25 minutes. A detailed manual is included. Published studies are available upon request.
