Spaceflight Standard Measures: Cognition (SSM_Cognition)
Principal Investigator
Research Area:
Behavior and performance
Species Studied
Scientific Name: Homo sapiens Species: Human


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.
