Visual targets will be presented to subjects via laptop for evaluations based on 5, 12, and 38 second intervals. Crew will give their best estimates for the duration of time in which a blue square is displayed on the screen. Minutes, hours, and days will be evaluated using a questionnaire. A standard reaction time test is also used to assess alertness and fatigue. The visual target testing, questionnaire, and reaction time test will be repeated for 3 preflight, 6 inflight, and 3 postflight sessions for comparison.
Information will be collected and evaluated to determine the relationship between:Duration production and reproduction
Single tasks and dual tasks
Preflight and inflight measurements
Inflight measurements and various durations of microgravity exposure
Early and late postflight measurements
Results for this investigation are unavailable. This is an international experiment. NASA does not currently have an agreement with international space partners to archive their data in the LSDA.
