In general fatigue is introspectively describable in terms of kinaesthetic relaxation and low attentive ebb of ideas with an affective aspect of indifference, sometimes bordering on mild pleasantness. Galvanic responses taken by both the Hathaway apparatus and a highly sensitive D'Arsonval galvanometer show marked individual differences with a general tendency toward lower bodily resistance under fatigue. Two types of fatigue are distinguished: cognitive fatigue and bodily or physical fatigue. Under some experimental conditions both types may be combined. The galvanometric response varies with each type. Muscular fatigue, due probably to continued residual twitchings and tremblings, tends to show increased response, while cognitive fatigue usually shows diminished response. The technique and results are given in detail.
