Symptoms
Extreme levels of mental fatigue lead to incompetence and irritability. Studies that require participants to carry out attention-demanding tasks under conditions of high distraction reveal how unpleasant a mentally fatigued person can be. After exposure to such an experience, individuals are less likely to help someone in need. They are also more aggressive, less tolerant, and less sensitive to socially important cues. Fatigue that is experienced by participants of these kinds of studies is induced by attention-intensive tasks, and the observed effects of such fatigue are correlated with decline in inhibitory control. Signs of Directed Attention Fatigue include temporarily feeling unusually distractible, impatient, forgetful, or cranky when there is no associated illness. In more severe forms, it can lead to bad judgment, apathy, or accidents, and can contribute to increased stress levels.
There are 6 major areas of mental processing that are affected during onset of DAF, which are as follows:
-
- Input- One may experience misperception and miss social cues.
- Thinking- One may experience feelings of restlessness, confusion, forgetfulness and/or decreased metacognition.
- Behavior- One may experience feelings of impulsiveness and recklessness, and may find that they have a diminished level of threshold between thoughts and actions. One may also act out-of-character.
- Executive Functioning- One may experience an inability to plan and make appropriate decisions, and may experience impaired judgment ability.
- Emotions- One may experience short-temperedness and feelings of unpleasantness.
- Social Interactions- One may experience heightened irritability and increased frequency of antisocial feelings.
Overlap of symptoms from the six above categories is highly indicative of Directed Attention Fatigue.

Famous quotes containing the word symptoms:
“There is one great fact, characteristic of this our nineteenth century, a fact which no party dares deny. On the one hand, there have started into life industrial and scientific forces which no epoch of former human history had ever suspected. On the other hand, there exist symptoms of decay, far surpassing the horrors recorded of the latter times of the Roman empire. In our days everything seems pregnant with its contrary.”
—Karl Marx (1818–1883)
“A certain kind of rich man afflicted with the symptoms of moral dandyism sooner or later comes to the conclusion that it isn’t enough merely to make money. He feels obliged to hold views, to espouse causes and elect Presidents, to explain to a trembling world how and why the world went wrong. The spectacle is nearly always comic.”
—Lewis H. Lapham (b. 1935)
“Murderous desire, hatred, distrust are nowadays the accompanying signs of physical illness: so thoroughly have we embodied our moral prejudices.—Perhaps cowardice and pity appear as symptoms of illness in savage ages. Perhaps even virtues might be symptoms.”
—Friedrich Nietzsche (1844–1900)
