Baudouin I4 distinguishes in heterosuggestion between acceptivity, the ease with which a suggestion is received from another person, and suggestibility > the capacity of a person for realizing an idea whatever has been its origin. He states that acceptivity is an undesirable factor, but that without an exaggerated acceptivity a high degree of suggestibility is a source of strength and is to be desired. It is, of course, suggestibility in this restricted sense and not acceptivity that is brought into play in autosuggestion.
He also distinguishes between spontaneous autosuggestions, in which the matter of the suggestions has caught the attention of the subject and been realized by him spontaneously, that is, without conscious intention ; and reflective autosuggestions in which the same process is deliberately initiated.
