BOREDOM--"In this age of semi-automation, when not only military personnel but also many industrial workers have little to do but keep a constant watch on instruments, the problem of human behavior in monotonous situations is becoming acute. In 1951 McGill University psychologist Donald O. Hebb obtained a grant from the Defense Research Board of Canada to make a systematic study. Prolonged exposure to a monotonous environment has definitely deleterious effects. The individual's thinking is impaired; he shows childish emotional responses; his visual perception becomes disturbed; he suffers from hallucinations; his brain-wave pattern changes."
