A person who practices or believes in autosuggestion, or a psychologist who specializes in studying or using autosuggestion therapeutically.
From 'autosuggestion' plus '-ist,' denoting a person who practices or advocates for something. The term emerged in early 20th-century psychology with the rise of autosuggestion therapy.
Émile Coué, the most famous autosuggestionist, had patients repeat affirmations hundreds of times daily—and it worked so well that his clinic in Nancy, France became packed with people from across Europe seeking his cures.
