The Nonsense Syllable Test (NST) (also known as the Edgerton-Danhauer Nonsense Syllable Test) is considered similar to a word recognition or speech discrimination test. It was developed because of negative clinical and research experiences with traditional word test materials. These traditional tests lack the sensitivity and reliability desired of them, especially when used with hearing-impaired patients as the sole measures of word recognition ability.
Several advantages of nonsense syllable materials over words include: increased analytic accuracy, less contamination by memory effects, less susceptibility to word familiarity effects, easier test construction and more sensitivity to the presence of auditory pathology.
These advantages have been known for some time, but there has been a reluctance to use nonsense syllable tests because of so-called difficulties in administration and scoring. However, with few exceptions, all the data collected on the NST have shown that it is as easy to administer and score these as most of the traditional tests. The NST consists of two 25-element lists in six randomizations. It is considered suitable for both children and adults.
The Nonsense Syllable Test includes a) audio recording, and b) instructions and score form as printable pdf files. The nine-page instructions include background, scoring, and interpretation information. Normative data is included, but it is not age-specific because the test developer observed little or no age effects. Call 1-800-669-9065 (from US) or 314-416-1050 (outside the US) to order.
