We have made significant progress since our last Annual Report. In addition to our 2017 published work, we have submitted a manuscript which is now under peer review. 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 strongrelationship with performance level, and have identified compelling interactions between age, type of task, 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. Our second manuscript is under review in a high-tier sleep research journal. We have applied for and been awarded a no-cost extensionto continue our work through 12312019. While continuing to analyze data on task performance, we are now analyzing sleep and chronotype effects on change in performance i.e. learning. We are submitting a letter of intent to apply for a DoD expansion award to build on our findings from this Discovery Award.
