Opportunity Description

Title of Research Opportunity: Interaction between cognitive and physical fatigue. Our recently published investigation provided evidence that a relationship between physical and cognitive performance may exist (Head et al., 2016; Head et al., 2017). In line with the Dismounted Soldier and Team Performance branch’s mission statement, we will examine the interaction between cognitive performance and physical fatigue in a control laboratory setting. Physiological measures (electrocardiogram and electromyography), blood markers (creatine kinase), cognitive performance (vigilance task), behavioral measures (body sway), and subjective-state questionnaires will be utilized to understand the relationship between physical fatigue and cognitive performance. We are seeking a research associate who can help with participant recruitment, phlebotomy, data collection, post processing and analyzing heart rate variability data. Potential candidates must be U.S. citizen and be experienced or willing to learn phlebotomy, and basic programming in R. References Head, J., Tenan, M. S., Tweedell, A. J., LaFiandra, M.
