Neurocognitive performance using the Windows spaceflight cognitive assessment tool (WinSCAT) in human spaceflight simulations

Data from the first 8 months of the Mars500 experiment (a 520-day simulation of a spaceflight mission to Mars, conducted in a chamber with 6 crewmembers) was collected using the WinSCAT computerized neurocognitive battery. Different hypotheses regarding reaction time, attention, and cognitive performance were analyzed, focusing on age-dependent differences and differences between language groups (Russian/other). The WinSCAT battery was able to detect differences in reaction time and accuracy. These results suggest future directions and implications for cognitive performance and neuropsychological assessment tools in human spaceflight.
