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. Available from Auditec, Inc.
