Sponsor's own description
The project will contribute with new knowledge concerning how short rest periods between two consecutive shifts (\<11h, often defined as a Quick Return (QR)) affects sleep and cognitive performance. The study will further examine whether individual differences in personality traits and genotypes may explain individual differences in performance and sleep. Data will be collected with a randomized cross-over design, in an experimental laboratory setting.
