Increasing Cognition Administration Order Flexibility (NCC958NBPF00012)
Principal Investigator
Research Area:
Species Studied
Scientific Name: Homo sapiens Species: Human

The study will provide regression estimates that adjust for the effects of both administration order such as practice effects and difficulty of stimulus sets which vary between batteries. These can be used to make all Cognition administration regimens comparable. This study will also show whether practice effects differ depending on the interval between Cognition administrations, which will inform pre- and in-flight testing schedules.

This study has the following specific aims:

  1. Disentangle practice effects and stimulus set difficulty effects to make Cognition administration more flexible.
  2. Investigate the effects of administration rate of the Cognition test battery on practice effects.

Human Research Program (HRP) Human Research Roadmap (HRR) Information
Crew health and performance is critical to successful human exploration beyond low Earth orbit. The Human Research Program (HRP) investigates and mitigates the highest risks to human health and performance, providing essential countermeasures and technologies for human space exploration. Risks include physiological and performance effects from hazards such as radiation, altered gravity, and hostile environments, as well as unique challenges in medical support, human factors, and behavioral health support. The HRP utilizes an Integrated Research Plan (IRP) to identify the approach and research activities planned to address these risks, which are assigned to specific Elements within the program. The Human Research Roadmap is the web-based tool for communicating the IRP content.
