Circadian rhythms are biological cycles that control the timing of various processes within living organisms. Particularly, circadian rhythms and the light influence sleep/wake processes. We explored whether factors other than circadian rhythms or light influenced waking time in humans. On a chair located near the bed of the experimenter was placed an analogue alarm clock face up, separated by a screen. The experimenter inspired himself to wake up, if possible, at certain “exact” moments (target points) 00 min, 15 min, 30 min, and 45 min during any hour, with recording the time of waking up. In the first stage of the investigation (the Experiment 1), the alarm clock showed the correct time. The second stage of research (the Experiment 2) wa...
