Field of Application+

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.
