Acceptability of the Cognition Test Battery in Astronaut and Astronaut-Surrogate Populations.

Background: Sustained high levels of astronaut cognitive performance are a prerequisite for mission success. A neuropsychological battery of 10 brief cognitive tests (Cognition) covering a range of cognitive domains was specifically developed for high performing astronauts to objectively assess cognitive performance. Extended mission durations require repeated cognitive testing and thus high acceptability of the Cognition software to the astronaut population.

Cognition Test Battery Performance Is Associated with Simulated 6df Spacecraft Docking Performance.

Environmental and operational stressors commonly encountered in spaceflight can affect astronaut cognitive performance. It is currently unclear how performance decrements on test batteries that assess individual cognitive domains translate to complex operational performance. 30 healthy adults (mean SD age 33.

Cognition test battery: Adjusting for practice and stimulus set effects for varying administration intervals in high performing individuals.

Introduction: Practice effects associated with the repeated administration of cognitive tests often confound true therapeutic or experimental effects. Alternate test forms help reduce practice effects, but generating stimulus sets with identical properties can be difficult. The main objective of this study was to disentangle practice and stimulus set effects for , a battery of 10 brief cognitive tests specifically designed for high-performing populations with 15 unique versions for repeated testing.

Cognitive Performance During Confinement and Sleep Restriction in NASA's Human Exploration Research Analog (HERA).

Maintaining optimal cognitive performance in astronauts during spaceflight is critical to crewmember safety and mission success. To investigate the combined effects of confinement, isolation, and sleep deprivation on cognitive performance during spaceflight, we administered the computerized neurobehavioral test battery "Cognition" to crew members of simulated spaceflight missions as part of NASA's ground-based Human Exploration Research Analog project. Cognition was administered to = 32 astronaut-like subjects in four 1-week missions (campaign 1) and four 2 weeks missions (campaign 2), with four crewmembers per mission.

Effects of acute exposures to carbon dioxide on decision making and cognition in astronaut-like subjects.

Acute exposure to carbon dioxide (CO) concentrations below those found on the International Space Station are reported to deteriorate complex decision-making. Effective decision-making is critical to human spaceflight, especially during an emergency response. Therefore, effects of acutely elevated CO on decision-making competency and various cognitive domains were assessed in astronaut-like subjects by the (SMS) and test batteries.
