“Jumping Frenchman of Maine disorder” is an extremely rare condition which entails an exaggerated “startle reflex”. The condition earned its name in Northern parts of Maine, 1878, when an unusually high amount of French Canadian lumberjacks were observed screaming in high-pitched tones at the slightest provocation.
Along with the over-sensitive “startle reflex”, sufferers experience a heightened state of suggestibility. George Miller Beard, who first observed the condition, found that yelling a sudden command to a person suffering from the disorder would cause them to immediately obey that command, even if the command was to hit a spouse.
The condition is extremely rare today and psychologists are still unsure if the disorder is psychological or neurological.
