Stress Vs. Mental Fatigue
The concept of stress is used in many situations that would be described as mental fatigue, but two concepts are distinctly different. Stress involves preparation for an anticipated event that has been evaluated as being threatening or harmful. Though mental fatigue may well result from such circumstances, it also arises out of hard work on a project one enjoys. In such cases, there is no anticipation involved and no threat of harm is present. Characteristic of mental fatigue is difficulty focusing. For a mentally fatigued person, paying attention to something uninteresting is burdensome, even though focusing on something of great interest poses no particular challenge. Hence, there are two types of attention, distinguished in terms of the effort involved in their use and their changes in attentional shift:
-
- Involuntary attention refers to attention that requires no effort at all, as when something exciting or interesting happens.
- Voluntary attention, or directed attention, refers to attention that requires a great deal of effort, as when something is monotonous or boring.

“Like all weak men he laid an exaggerated stress on not changing one’s mind.”
—W. Somerset Maugham (1874–1966)
“It was at a particular moment in the history of my own rages that I saw the Western world conditioned by the images of Marx, Darwin and Freud; and Marx, Darwin and Freud are the three most crashing bores of the Western world. The simplistic popularization of their ideas has thrust our world into a mental straitjacket from which we can only escape by the most anarchic violence.”
—William Golding (b. 1911)
“He is asleep. He knows no longer the fatigue of the work of deciding, the work to finish. He sleeps, he has no longer to strain, to force himself, to require of himself that which he cannot do. He no longer bears the cross of that interior life which proscribes rest, distraction, weaknesshe sleeps and thinks no longer, he has no more duties or chores, no, no, and I, old and tired, oh! I envy that he sleeps and will soon die.”
—Albert Camus (1913–1960)
