Abstract

The results of this experiment were obtained from three subjects who went without sleep from the ordinary rising time one day until the ordinary retiring time the second night following, a period of from sixty to sixty-five hours. The subjects were given dynametric, reading, aiming, tapping, and mental multiplication tests once each day beginning several days before the period of insomnia and continuing four or five days after the insomnia. Qualitative effects from loss of sleep, such as nervousness, headache, dizziness, irritability, disturbance of speech, and the like, were more or less marked in all three O's. The quantitative data from the tests, however, were practically negative. In so far as the scores showed any positive effect, they showed a deleterious one. But with the exception of one or two cases the variations in performance during the period of insomnia were no wider than the variations preceding or following insomnia.
