Detailed Description+

Assesses visual working memory.
One of the most important tasks performed by working memory is to maintain and update visual material (verbal material is assessed by the test N-Back verbal NBV). In NBN the item material is difficult to verbalize: this ensures that apart from the central executive only the visual components of working memory are involved. The item design involves consistent implementation of the 2-back or 3-back paradigm. Disorders of working memory are well documented in a number of neurological and mental illnesses, such as Parkinson's disease, Huntington's chorea, ADHD and Alzheimer's disease. The test is therefore used mainly in clinical neuropsychology.

Test forms+

Task+

Highly abstract figures are presented one by one. The respondent’s task is to state whether the figure 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 variables are scored:

  • Correct and omissions: Measure of the ability to maintain and constantly update visual memory representations.
  • Incorrect: Misjudgments – Measure of the executive abilities in goal management.

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.
