We have made significant progress since our last Annual Report. In addition to our 2017 published work, we have performed analyses on tasks assessing cognitive domains of selective attention, response inhibition, cognitive flexibility and task switching. We have replicated our published findings with respect to sleep duration using different tasks, have found that chronotype and task-time aligned with chronotype do not appear to markedly impact performance but that time-of-day has a strong relationship with performance level, and have identified compelling interactions between sleep duration, time-of-day and chronotype variables on cognitive performance. We have also found some interesting preliminary findings with respect to sleep and mood. We are preparing a follow-up manuscript based on new findings and are continuing to perform analyses on additional tasks for which our industry collaborator has collected datasets large enough for addressing ourresearch questions. While continuing to analyze data on task performance, we are progressing to our analyses with respect to the relationship of sleep and chronotype effects on change in performance i.e. learning. We are also currently preparing a DoD grant submission based on our findings to date.
