Informational Stress: Discussion Paper [PDF]

open access: yesJournal of the Royal Society of Medicine, 1990
Stress can be caused by a multitude of factors requiring the capacity for adaption by the organism. As well as physical, chemical and biological factors, information may also become a stressor in certain circumstances. Stress may be induced just as well by too little as by too much information, and by the quality of the information.
