This 12-item test is a non-verbal screening of both odor discrimination and memory. It provides an overall score, as well as a test score, for each of the three delay intervals: 10, 30 & 60 seconds. Following the release of an inspection odor, four alternatives are presented after a given delay interval. The subject is required to identify which odor corresponds to the inspection odor. This test is highly reliable (test-retest r=0.80) and is useful in many research and clinical test situations. Minimum order 7 tests.
