    Detailed Description+

    Assesses verbal working memory.
    One of the most important tasks performed by working memory is to maintain and update verbal material (visual material is assessed by the test N-Back non-verbal NBN). The test uses the N-back paradigm.
    The NBV makes demands on both (a) a specific function of verbal working memory, the updating of contents, and (b) the ability to operationalize verbal working memory “overall”. Disorders of working memory occur in a number of clinically relevant illnesses and injuries, such as Alzheimer's disease, Parkinson's disease and ADHD. The test is therefore used mainly in clinical neuropsychology.
