Onset
The onset of directed attention fatigue can be triggered by a number of activities, all of which involve use of the brain’s inhibitory system. Activities that engage this system include multitasking, working in an environment with disruptive background noise or after a lack of sleep, and rapidly changing focus during a prolonged period of attention. DAF can also be brought about by performing concentration-intensive tasks such as puzzle solving or learning unfamiliar ideas. External factors such as stress resulting from emergencies, exams or work deadlines can also induce DAF. Any illness or injury to the brain that interrupts the brain circuits involved in maintaining attention and inhibiting external stimuli may also contribute to the development of directed attention fatigue.

Famous quotes containing the word onset:
“While the onset of puberty can vary by as much as six years, every adolescent wants to be right on the 50-yard line, right in the middle of the field. One is always too tall, too short, too thin, too fat, too hairy, too clear-skinned, too early, too late. Understandably, problems of self-image are rampant.”
—Joan Lipsitz (20th century)
