In France, we have a famous pharmacist and psychologist, Emile Coué (1857 – 1926) whose name became known thanks to his method: “la méthode Coué”. Or Couséism as in the couscious autosuggestion.
I remember when I was younger my parents would tell me when I would struggle to learn to do something: “use the Coué method”. They were referring to the action of repeating things over and over again until they become part of you. It was not necessarily an accurate use of it but you get the idea.
