Mean (± SE) Visual Analogue Scale (VAS) scores for the subjective perception of alertness, calmness, contentment, speed-of-time-passing, and brightness of colors. Scores range from 1 to 100 with 50 indicating a neutral state. The lower the score, the more the subject identifies with the leftmost adjective of the 100 mm line (i.e. alert, calm, contented, time slowed, colors dull).
