Description
This popular measure of intellectual ability and impairment has been used with millions of individuals 14 years of age and older. The Scale is composed of two brief subtests: (1) a 40-item Vocabulary Test that requires the respondent to choose which of four listed words “means the same or nearly the same” as a specified target word; and (2) a 20-item Abstract Thinking Test, which requires the respondent to fill in numbers or letters that logically complete a given sequence. The Shipley measures the discrepancy between vocabulary and abstract concept formation, providing a useful measure of cognitive impairment. In addition, it is widely used as a convenient intelligence measure because it is self-administering and brief and can be individually or group administered.
