The Western Aphasia Battery or WAB is an instrument for assessing the language function of adults, able to discern the presence, degree, and type of aphasia. Another such test is the Boston Diagnostic Aphasia Examination. The aphasia quotient (AQ) is the summary score that indicates overall severity of language impairment.
The WAB–R, a full battery of 8 subtests (32 short tasks), maintains the structure and overall content and clinical value of the current measure while creating these improvements:
- Two new supplementary tasks (reading and writing of irregular and non-words) will aid the clinician in distinguishing between surface, deep (phonological), and visual dyslexia.
- Revision of approximately 15 items
- Bedside WAB–R – provides a quick look at patient’s functioning
- Examiner’s manual with technical/psychometric properties information, test interpretation relevant to aphasic populations, historical evidence of reliability and validity, and information about the unique aspects of assessing the language ability of individuals with dementia
- Spiral-bound stimulus book replacing loose stimulus cards
- Revised administration directions – more user-friendly with directions to the examinee for all subtests
- Expanded scoring guidelines for clarity
- It helps classification of Aphasia into different types.

“It is the place where all the aspirations of the Western World meet to form one vast master aspiration, as powerful as the suction of a steam dredge. It is the icing on the pie called Christian civilization.”
