The Cognition test battery is one of nine Spaceflight Standard Measures conducted on International Space Station (ISS) crewmembers. Spaceflight Standard Measures are a set of core measurements, representative of many of the risks experienced by astronauts before, during, and after spaceflight. The purpose of this project is to populate a repository with data that enables high-level monitoring of countermeasure effectiveness and meaningful interpretation of health and performance outcomes. These standard measures will support future, hypothesis-driven research that enables planetary missions by providing an optimized minimal set of measures captured from all ISS crewmembers until the end of the ISS program. These measures will be available to other studies under data sharing agreements as well as undergo analysis for trends in the astronaut population.
The Cognition test battery is used to analyze and provide a streamlined way of evaluating focus in different aspects of cognitive function, such as, visual object learning, memory, attention, abstraction, spatial orientation, emotion recognition, abstract reasoning, complex scanning and visual tracking, risk decision making, sensorimotor ability, and vigilant attention. To initialize this, a software-based combination of 10 brief tests will be conducted.
The participant will complete a battery of tests designed to assess cognitive performance using the Cognition software. The subject will be given an overview of the Cognition software and will complete a practice test on laptop provided by lab personnel. The Cognition test battery will be preceded by a short list of questions about sleep time/duration, caffeine/alcoholic beverage, medication consumption, and alertness level.
During the mission, the subject should perform the Cognition tests on the same computer each time in order to provide accurate feedback and to ensure sequential completion of tests. Collection will occur pre-, in- and post-flight under three mission scenarios: short duration (up to 105 days flight days), standard duration (between 105 to 240 flight days), and long duration (greater than 240 days).
For the Cognition session, the scheduled days of collection will be as follows:
Short Duration Mission:
Standard Duration Mission:
Long Duration Mission:
The Spaceflight Standard Measures project is not a hypothesis-driven study, but rather a project to create a collection of ISS data made available to future researchers and for trend analysis. As such, there are no specific hypotheses, outcome measures, or statistical analyses associated with the skeleton of the project. The project will capture a "snapshot" of optimized data that can be investigated by researchers in the future.
