What does each subtest of CNS Vital Signs measure?
The CNS Vital Signs neurocognitive assessment captures an objective view of five basic mental functions: memory, psychomotor speed, reaction time, complex attention and cognitive flexibility. The battery consists of seven subtests which in different combinations compose the above five cognitive domains. CNS Vital Signs includes parallel tests of verbal memory (word list learning) and visual memory (figure learning). The tests are virtually identical, but one uses words as stimuli, the other, geometric shapes. The Finger Tapping Test generates relevant data about fine motor control, which is based on motor speed as well as kinesthetic and visual-motor ability. The Symbol Digit Coding Test generates data included in a composite score for psychomotor speed. The Stroop Test gives important data about reaction time, or, to be more precise, information processing speed. The Shifting Attention Test measures the subjects ability to shift from one instruction set to another quickly and accurate
