Token Test
Please visit this website for more information about the instrument: Token Test.
Exploratory: Unruptured Cerebral Aneurysm and Subarachnoid Hemorrhage (SAH)
Short Description of Instrument
Purpose: The Token Test is used to assess auditory comprehension in persons with developmental and acquired disorders affecting language. The examinee provides a gestural response in response to a verbal command.

The Token Test is excellent for detecting mild auditory comprehension deficits, but less useful for assessing other aspects of auditory comprehension (such as semantic comprehension) or functional communication.

Scoring: The test is scored on a scale of 0–163. A sample of a Token test scoring sheet can be found on the web link provided above. The mean score for adults (and adolescent 14 years or older) is 161. Scores lower than 157 are virtually absent in a normal adult population.
