Science Report 2

Tonya Thompson Reporting

I performed 3 psychophysiological reading sessions on each crewmember today. Each session lasted 3 minutes.

The crewmember entered my stateroom, sat in a chair, placed finger sensors on their 3 middle fingers, and watched a white image projected onto a wall for 3 minutes. During that time, I recorded their heart rate variability (hrv) and skin conductance level (scl). The data for each session was saved to the hard drive of a desktop pc in my stateroom.

I also had each crewmember fill out a Cohen’s Perceived Stress Scale questionnaire at the end of the evening after dinner.
