Performance After Awakening at Different Times of Night

Abstract

Naval ratings were roused during the night and presented themselves, dressed, for testing in a nearby room with 4 minutes. During the next 11 minutes they were given tests of reaction time, calculation and muscular co- ordination and steadiness. In all three tests performance was well below the normal level achieved during the day. On different occasions the men were aroused at different times of night and this factor influenced which task was affected most. Reaction time, with its intermittent call for rapid response, was impaired most in the early part of the night; the adding and co-ordination, which demanded more continuous performance, were more affected later in the night.
