Eckhard H Hess b. 1916
Eckhard Hess was a professor of behavioural science and a
leading authority on imprinting, a psychological phenomenon by which an
animal's early experience permanently determines its subsequent behaviour, and
a pioneer in pupillometrics, a field of psychology based on thoughts and
emotions as revealed through the eye. The pupil, according to Hess, is the
body's natural lie detector and a type of window to the brain. He found that
changes in attitude can be detected by measuring changes in pupil size, and that
the enlarged or constricted pupils can also affect the attitude and responses
of the person who observes them.
