Water-Loading Test in Mental Diseases

Archives of Neurology And Psychiatry, 1959
Water metabolism in mental diseases is an interesting problem. Earlier findings have been summarized by Altschule 1 in 1953. He recalled the widely divergent factors complicating this matter. Emotional experiences have a profound influence on water metabolism. 2 Both emotional and physical stimuli can inhibit diuresis by releasing antidiuretic hormone.

Sinus Arrhythmia as a Measure of Mental Load

Ergonomics, 1974
This experiment examines the proposition that sinus arrhythmia is a measure of mental load. The experiment involved a subtraction task in which the physical and mental loads could be varied independently. The results indicate that sinus arrhythmia does decrease with on increase in mental load.
