The Cognitive Function Scanner (CFS) is a Neuropsychological test battery originally developed by Peter Laursen, DMedSci, DPsySci, and Thomas Sams, PhD, for the Danish National Institute of Occupational Health in the early 1980s. It is a computer-aided cognitive assessment system consisting of a battery of neuropsychological tests, administered to subjects using computer screen, a dedicated keyboard and a graphics tablet as stimulus and response media, respectively. The nine tests in CFS examine various areas of cognitive function, including:
- Short-term and long-term verbal memory (words and numbers)
- Short-term and long-term visual memory (faces)
- Working memory (numbers)
- Visuomotor function (continuous and discrete for each hand)
- Visuospatial function
- Reaction time and
- Vigilance (visual and auditory).
The CFS takes advantage of the precision and rigor of computer technology, whilst retaining the wide range of ability measures demanded from a neuropsychological battery. In contrast to other cognitive test batteries and in addition to its psychometric measures, the later versions of CFS includes detailed recording of every step of the full response process in all tests (collection of qualitative data to support interpretation of every psychometric outcome). Cognitive Function Scanner was one of the first psychological test methods to include an artificial neural network for scoring a test. The CFS is suitable for subjects aged 10+. Norms standardized on age, gender and education are based on a sample of 1,026 of the general Danish population, with an age range of 25–75 years. The CFS aims to be culture and language independent through the use of non-verbal stimuli in all tests, except the Word Learning and Memory Tests.
