Aims:

Specific aims of this project are twofold: (1) develop a methodology to assess cognitive and emotional state “at a distance” through spontaneous verbal output in real-time communications and (2) produce a real-time assessment tool to detect cognitive performance deficits, stress, fatigue, anxiety, and depression in the spaceflight operational setting. Primary tasks for the first year include: (1) the development of a working model of cognitive performance deficits, stress, fatigue and anxiety in spaceflight and (2) the generation of a lexicon (in American English) indicative of these constructs. Second and third years of the project will focus on the validation of the lexical methodology through a multi-level empirical research. The primary tasks include: (1) validation via archival analysis of previously collected data, (2) validation studies conducted with representative and analogue populations, and (3) delivery of a transparent system which allows for real-time assessment and graphical display of stress processes drawn from ongoing verbal or textual communications. These tasks will afford an investigation of the topography of shifts in lexicon word use over the course of individual and team performance, examine lexicon word use to gauge stress effects, cognitive load, anxiety, etc., and predict individual and team performance outcomes.

Mappings
RiskRisk of Adverse Cognitive or Behavioral Conditions and Psychiatric Disorders
GapBMed-101: We need to identify, quantify, and validate the key selection factors for astronaut cognitive and behavioral strengths (e.g., resiliency) and operationally-relevant performance threats for increasingly Earth independent, long-duration, autonomous, and/or long-distance exploration missions.
GapBMed-102: Given exposures to spaceflight hazards (space radiation, isolation), how do we identify individual susceptibility, monitor molecular/biomarkers and acceptable thresholds, and validate behavioral health and CNS/neurological/neuropsychological performance measures and domains of relevance to exploration class missions?
GapBMed-108: Given each crewmember will experience multiple spaceflight hazards simultaneously, we need to identify and characterize the potential additive, antagonistic, or synergistic impacts of multiple stressors (e.g., space radiation, altered gravity, isolation, altered immune, altered sleep) on crew health and/or CNS/ cognitive functioning to develop threshold limits and validate countermeasures for any identified adverse crew health and/or operationally-relevant performance outcomes.
