Abstract
17 college students (13 men, 4 women) went without sleep for 100 hours. 18 standardized psychological tests (reaction-time, A.C.E. psychological examination, tapping, visual acuity, color zones, hand steadiness, memory, etc.) and 6 measures of physiological functioning (blood pressure, temperature, patellar reflex, etc.) were given before and after, as well as during the sleepless period. 10 control S''s also took the tests. Results obtained corroborate those of earlier investigators. Physiological functioning appeared unaffected. In the psychological tests some S''s maintained the level of their performance, even after 72 or 96 hours without sleep, but at the expense of tremendous effort. Static ataxia increased for most S''s and showed large and definite effects of loss of sleep. From 11-30 abnormal symptoms (dizziness, inattention, hallucinations, headache, etc.) appeared in all S''s. Women did as well as the men. In general, the stronger and more athletic men suffered the most.This publication has 1 reference indexed in Scilit:
