~ auditecinfo ~ 4 Comments

The Dichotic Digits-Standard© test is an auditory processing disorder test using verbal stimuli. It is considered a dichotic test for binaural integration sensitive to brainstem, cortical, and corpus callosal lesions.

This established test assesses the ability to process different materials arriving at the ears simultaneously. Fifty sets of digits, one through nine (except seven, having two syllables) are presented either in single pairs or double pairs. The digits begin and end simultaneously. Administration time is approximately ten minutes.

Dichotic Digits-Standard© includes a) audio recording, and b) instructions and score forms as printable pdf files. The one-page instructions consist of administration, scoring, and interpretation information. Normative data¹ for double digits is included; however, it is only available for ages 11 and up.

Dichotic Digits-Musiek©

~ auditecinfo ~ 3 Comments

The Dichotic Digits test is an auditory processing disorder test for ages 7 and up using verbal stimuli. It is considered a dichotic test for binaural integration sensitive to brainstem, cortical, and corpus callosal lesions.

Dichotic Digits – Musiek© is a test by Dr. Frank Musiek. This version is similar to the Dichotic Digits standard version.  That is, digits from one to ten are presented dichotically.  One set is single pair; the second is double pair.  Usually, the single pair set is for practice. Dichotic Digits-Musiek version includes the digit “seven.” In contrast, the standard version does not include the digit “seven” since it is a two syllable word in contrast to the other nine digits. The Musiek version includes age-specific normative data on double digits for ages 7 and up. The standard version includes normative data on double digits for ages 11 and up.

Is the Musiek version or standard version better? Neither version is considered better. Both versions are popular and widely used. Decisions are mainly based on which version the audiologist was originally trained in or by personal preference. Due to the similarities between the standard and Musiek versions, it is usually unnecessary to purchase both versions.

Dichotic Digits-Musiek© includes a) audio recording, and b) instructions and score form as printable pdf files.  The two-page instructions consist of administration, scoring, and interpretation information. It includes age-specific normative data on double digits for ages 7 and up.

Pediatric Speech Intelligibility©

~ auditecinfo ~ 5 Comments

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 and two sets of sentences recorded in quiet and with competition (auditory figure ground). The test employs color plates with pictures of animals (animals were used 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.

Competing Sentences©

~ auditecinfo ~ 7 Comments

The Competing Sentences© is popular with both psychologists and audiologists. It is an auditory processing disorder test and is considered a dichotic sentence test for binaural separation sensitive to neuromaturation and language processing. It uses verbal stimuli and is appropriate for ages 5 and older. It consists of 30 pairs of sentences with similar subject matter within each sentence pair. These sentences were recorded so that each pair begins and ends simultaneously. Administration time is approximately 7 minutes.

Competing Sentences© includes: a) audio recording, and b) instructions and sentence list. The two-page instructions encompass format, procedure, and interpretation. Normative data for ages 5, 6, 7, 8, 9, and 10. At age 10, normal scores are 100% in both ears so it can be assumed that normal patients over age 10 would achieve similar results.

Dichotic Word Listening Test©

~ auditecinfo ~ 8 Comments

The Dichotic Word Listening Test© (DWLT) is popular with audiologists and psychologists. It is often considered an auditory processing disorder test. It was developed specifically to demonstrate relative unilateral extinction or suppressions in neurologic patients with focal electrophysiological lesions, neuropsychiatric patients whose symptoms are presumed to be associated with underlying electrophysiological dysfunction and patients with so-called “subclinical” EEG abnormalities following closed head injury. Since observations indicate that multiple neuropathological processes impair dichotic listening performance, the DWLT may prove relevant to investigation of brainstem disorders, subcortical lesions, etc.

The DWLT stimuli are common words varying in length from one to three syllables.  The test is in two equivalent parts with 10 practice items and 30 test items in each part.

The Dichotic Word Listening Test© includes a) audio recording, b) instructions and score forms as printable pdf files. The five-page instructions consist of background, administration, scoring, and interpretation. The instructions include grade-specific normative data for kindergarten, 2nd, 4th, and sixth grades as well as adults.
