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.

Test forms+

S1: 2 back standard form
S2: 2 back parallel form

Task+

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.

Scoring+

The following main variable is scored:

Correct: Measure of the ability to recall memory representations from short- and long-term memory, store them in the short term and continuously update them.

The subsidiary variables Mean time “correct”/”incorrect” function as a measure of working speed and reaction speed; they are independent of the quality of the respondent’s answers.
