| description | From a psychometric point of view, cognitive performance in humans has to be examined as a multidimensional quantitative construct. Models of memory and intelligence may serve to describe the complex interactions of cognitive functioning. Based on memory research and reliable psychometric methods a three-dimensional model including
“Primary Memory”, “Secondary Memory” and a
“Speed factor” is proposed. Using models of intelligence
“Fluid Intelligence” and
“Crystallized Intelligence” are outlined as separate performance factors.
“Cognitive Speed” is demonstrated as a market variable of
“Fluid Intelligence”. It is shown, that
“Cognitive Speed” is clearly age-associated and constitutes a key function for other cognitive domains and for activities-of-daily-living. Furthermore
“Cognitive Speed” is a crucial cognitive domain to separate normal from pathological aging. As an example to assess “Cognitive Speed”, the Zahlen-Verbindungs-Test G (1), a modified trail-making test, is discussed to diagnose beginning and ongoing dementias. |
