The image depicts a line graph titled Interaction Plot E E G Calm State by Time Slot and Environment Type. The x-axis shows Time Slot values 8:00 to 9:00, 9:00 to 10:00, 10:00 to 11:00, 11:00 to 12:00, 13:00 to 14:00, 14:00 to 15:00, 15:00 to 16:00, 16:00 to 17:00, and 18:00 to 19:00. The y-axis shows Calm state E E G value percent. Two lines represent Home and Office. Both start high around 63 percent and 67 percent at 8:00 to 9:00, decline around mid-morning, rise near 13:00 to 14:00 to about 61 percent and 64 percent, then decrease again in the afternoon with smaller fluctuations.Mean EEG Calmness (%) across time-of-day periods in home and office work environments
