Effect of varying periods of sleep on nervous stability

Abstract

Tests were made on five subjects after varying periods of sleep. The Moss Wabblemeter Test was used. A close relation was found to exist between length of previous sleep period and nervous stability. Nervous stability is far less after two hours of sleep than at bedtime after a strenuous day. Nervous stability increases with increasing amounts of sleep. It is found to be at a maximum in the early afternoon, a warming-up period evidently being essential to greatest efficiency. (PsycInfo Database Record (c) 2025 APA, all rights reserved)
