Agoraphobia was the name given by Westphal (1871) to the fear of walking through streets and public places. The agoraphobic syndrome, which covers much else and includes fear of confined spaces, crowds, travelling and shopping, was carefully defined by Marks (1969). His full description and review revealed, perhaps surprisingly, that although the desire to escape rapidly from a feared situation has been clearly recognized in the literature, no detailed observation seems to have been made of the rate of locomotion in this condition.
A. Orwin (Thu,) studied this question.
