Description

In order to improve the capability to monitor and evaluate the neurocognitive (NC) status of the International Space Station (ISS) astronauts, the Canadian Space Agency (CSA) initiated the development of a novel tool called Performance Readiness Evaluation and Training Tool (PRET). PRET is based on a 3D virtual reality Mars mission simulator that offers multi-task activities embedded with NC tests. This would permit the assessment of a user’s neuropsychological performance in areas such as processing speed, memory, attention, and response control. The initial prototype software (Version 1) was developed in 2010. The PRET prototype went through initial usability testing during the Russian Mars500 isolation study and the software was updated based on this experience, resulting in Version 2). Subsequently, the Carleton University Advanced Cognitive Engineering (ACE) Lab was contracted to perform further testing and evaluation of PRET in a controlled laboratory setting. This was done in four test phases (Phase 1, Phase 2, Phase 3 and Phase 3 Extension). After each phase, the PRET software was further refined and updated. The goal was to verify PRET’s robustness, usability, and ability to detect and predict the neurocognitive readiness of astronauts in performing critical mission tasks. Further testing on the ground is required before space application. The provided data contains participant neurocognitive performance results measured using the PRET software (versions 1.0, 2.0, 3.0, 4.0, and 5.0), standardized neurocognitive tests (D-KEFS, PASAT, PVT, TOVA, WAIS-IV, and WMS-I), and standard neurocognitive assessment tools DANA and WinSCAT.
