Cognition is the mental act or process by which knowledge is acquired, including perception, intuition, and reasoning.

Domains of Cognitive Performance

When evaluating effects of spaceflight on cognitive performance, it is helpful to consider the broader context of measuring individual differences in performance and conditions that affect performance within individuals. Multiple measures have been developed by psychologists to assess performance on a wide range of domains, and selecting which to implement within time constrains of any specific project can be daunting. Traditional tests depend heavily on general intellectual abilities (“g factor”) as reflected in the “intelligence quotient” (IQ), and those targeting specific abilities that could be affected by spaceflight require large investment of time and instrumentation (Deary and Batty 2007). Traditional psychometric theory has generally divided cognitive abilities into language-mediated or “verbal” intelligence and...
