PSI

The Pediatric Speech Intelligibility Test is a test for children ages 3 to 6. It fits in two important auditory processing domains. It can be categorized as both a dichotic test and a monaural low-redundancy speech test (monaural separation closure-MSC) sensitive to low brainstem.

The importance of speech audiometry, especially where the test materials include both monosyllabic words and sentences, has been well established for adults. Experience with performance vs. intensity (PI) functions and message to competition ratio (MCR) functions with adults led to the development of an analogous test for children; the Pediatric Speech Intelligibility (PSI) test.

The PSI includes both monosyllabic words and sentences recorded in quiet and with competition (auditory figure ground). The test employs color plates with pictures of animals (animals were use to avoid ethnic biases) which represent either the sentences or the words. It is an extremely useful tool for the investigation of peripheral and auditory processing with children down to a language age of three or slightly younger.

The test includes: a) corresponding laminated color plates, b) audio test recording, and c) manual and score forms as printable pdf files. This extensive manual includes background, administration, and interpretation information including normative data for young children.

*What is the difference between the standard and basic version? Auditec recommends purchasing the PSI – Standard Version, which is the full test. It includes two sets of sentence materials which allows for re-testing without having to use the same sentences. However, Auditec also offers the PSI – Basic Version for those with budget restraints. The PSI – Basic Version includes only one set of sentences and should be used on patients who will be tested once.  (The PSI – Standard Version includes the PSI – Basic Version so it is unnecessary to buy both versions.)
