The W-22 Ordered by Difficulty Short Interval© is a word recognition or speech discrimination test. It consists of four lists of 25 words each selected by D. Rose so that they are ordered from most likely to be missed to the least likely. If the first 10 items (or 9 of the 10) are heard correctly, the test is halted, since it is assumed that an individual with word recognition difficulty will be most likely to miss the most difficult items. Persons who miss more than one of the first ten items are given the entire 25-word list.
This short-interval version of the test gives the patient 2.5 seconds to respond instead of the standard four seconds. It is yet another way to effectively speed up administration time, but this version is not recommended for young children or the elderly. The administration time will vary from 2-15 minutes depending on how well the patient performs.
The W-22 Ordered by Difficulty Short Interval© includes a) audio recording, and b) word list. This product does not include instructions or normative data. It is assumed that purchasers of Auditec’s products are well trained in their use, purpose, and interpretation.
