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.
S1: 2 back standard form S2: 2 back parallel form S3: 3 back standard form S4: 3 back parallel form
Consonants are presented one after the other. The respondent’s task is to state whether the consonant currently displayed is identical to the one shown two places back (2-back paradigm) or three places back (3-back paradigm). If it is, the respondent presses a button as quickly as he can.
