Strategies to Sustain and Enhance Performance in Stressful Environments

Abstract

This report contains the five manuscripts (one published, two in- press, one in-review, and one in-preparation) and six published abstracts completed during the three year grant period. These include descriptions of the four original research projects completed during the grant period. STUDY 1 was designed to test the Effects of illumination on human nocturnal serum melatonin levels and performance. Results indicate that overnight exposure to 300, 1500, or 3000 lux of light significantly diminished serum melatonin levels in a dose- dependent manner. Performance on vigilance, reaction time, and other tasks deteriorated throughout the night, consistent with known circadian variations in these parameters, but independent of ambient light intensity and circulating melatonin levels.
