N2  - In a series of 216 reactions the time in the second half is five per cent. greater than in the first. This is scarcely referable to fatigue in the ordinary sense of the term, since the muscular activity involved is negligible, and there is a rest period of 11 seconds between the reactions. The introspections show that the slightly darkened room, the regularity of the responses, and the monotony of the whole procedure induce ennui tending toward somnolence. This seems to carry with it a slightly increasing refractoriness to the reaction stimulus. From Psych Bulletin 18:12:00650. (PsycINFO Database Record (c) 2012 APA, all rights reserved)<p />
