Numerous observations of emotional phenomena similar in principle have been recorded in the case of Miss B.[177] These observations included automatic facial expressions of pleasure, anger, and fear. These expressions could always be traced to subconscious processes and in this case to actual ideas of a coconscious personality. But the principle is the same. _Sometimes the affect linked to the process welled up into consciousness and sometimes it did not._ When, in the case of Miss B., the automatic phenomena were determined by coconscious ideas it was because the perceptions of the secondary subconscious personality had a humorous, angry, or fear setting, as the case might be. These particular observations are of especial interest because they allow us to clearly distinguish _at almost one and the same moment the different manifestations corresponding to the different settings with which the same idea may be clustered_. While, for instance, the personal consciousness of Miss B. perceived a person or situation with apprehension and manifested this apprehension in her facial expression as well as verbally, the subconscious perception of the same person or situation was one of joy which broke through Miss B.’s apprehensive feature in automatic smiles. In other words, two different perceptions (with opposite meanings) of one and the same object functioned at the same time. These observations, as interpreted, are of wider significance in that they allow us to understand the mechanism of many phenomena of everyday life. For instance, the _hysteria of crowds_ may be explained on the same principle; likewise the outbreak of emotional physical manifestations in a person whose attention is absorbed (abstraction and distraction) in reading or hearing something (e. g., at a play), which, it may be inferred, touches some inner emotional experience of his life. In the kind of instance I have in mind introspection fails to reveal the presence of conscious thoughts or sometimes even emotions which adequately explain the physical disturbance. When not abstracted by the reading or play, the same ideas he was attending to a moment before fail to excite these disturbances. As has been said, “everyone is a little hysterical,” meaning that under certain conditions—particularly those of stress and strain and strong emotion—the mind becomes a bit disintegrated, and unconscious complexes manifest themselves through what are called hysterical symptoms.
