The next few pages will be devoted to an examination of the mental situations from which anger develops as found in the results of the introspections. About six hundred introspections from the various observers have been used for this study. _Feelings of Irritation._ One of the characteristic mental situations from which anger arises is that connected with feelings of irritation. These feelings are described as unpleasant nervous tension with a tendency to motor activity. Awareness of the feeling may be present while attention is directed elsewhere. It may or may not be referred to any particular incident. C.—“It is a sort of diffused unpleasant consciousness that things in general are going wrong.” Irritation in connection with pain or illness is a condition from which anger may develop. From this a trivial incident may give rise to anger. A note from E.’s records says, “I had a severe headache to-day and felt irritable. When X. would try to sympathize with me, the irritation would increase and I tended to be angry.” G, who has relatively few emotions of anger, introspected upon ten cases of anger, arising from a fore-period of irritation during a day’s illness. Subject I. states with reference to pain, “While the pain was on I felt as though I wanted to be angry at somebody or something, X. spoke to me and at once I was angry.” Feelings of irritation may increase, gradually, accompanying the increased intensity of pain. A. states, “Irritableness at the first beginning of the pain increased to intense anger at the moment the pain was most severe. There was a strong motor tension in the hands and face muscles with the impulse to look about, vaguely aware that I was trying to find something to refer the anger to.... A decrease of the pain was accompanied by a decrease of the anger to a feeling of irritation again.”
