Dopo l'estero-interocezione, il processamento degli input e la memoria Charles T. Tart introduce il quarto sottosistema del sistema della coscienza, il subconscio:
Subsystems
Subconscious
The Subconscious is usually defined as representing mental processes or phenomena that occur outside conscious awareness and that ordinarily cannot become conscious. They are part of the mind, but not conscious. How do we know they exist if we cannot be consciously aware of them? We infer their existence we observe certain aspects of our own and others' functioning that cannot be adequately explained on the basis of our or their immediately available conscious experiences, and we infer that forces or phenomena outside consciousness are affecting it—from behind the scenes, as it were. Thus, from the viewpoint of our ordinary d-SoC, the Subconscious subsystem is a hypothesis, an inferential construct needed to explain conscious behavior. A psychoanalyst, for example, observes that a patient becomes pale and trembles every time he speaks of his brother, yet when questioned about him says they have a good relationship. The psychoanalyst hypothesizes that in the patient's Subconscious there is a good deal of unresolved anxiety and anger toward the brother.
The emphasis here is that subconscious processes occur outside awareness from the viewpoint of the ordinary d-SoC. What is subconscious from the reference point of the ordinary d-SoC may become conscious in d-ASCs.
I deliberately use the term subconscious rather than the more commonly employed unconscious to avoid the strictly psychoanalytic connotations of unconscious mind. The classical, Freudian unconscious (the sexual and aggressive instincts and their sublimations and repressions) is included in the Subconscious subsystem described here. The Subconscious also include creative processes, the kinds of things we vaguely call intuition and hunches, tender and loving feelings that may be just as inhibited in their expression as sexual and aggressive ones, and other factors influencing conscious behavior. All these things are mysterious and poorly understood by our conscious minds.
Also included as subconscious processes for many of us are the kinds of thinking that are now called right hemisphere modalities of thinking. The type of thinking associated with the right hemisphere seems holistic rather than analytic, atemporal rather than sequential in time, more concerned with patterns than with details. But for many of us in whom intellectual, sequential, rational development has been overstressed and this other mode inhibited or ignored, this right hemisphere thinking is largely subconscious.
D-ASCs may alter the relationship between what is conscious and what is subconscious.
Figure 8-2 expresses this idea. In the ordinary d-SoC, it is convenient to think of the conscious part of the mind as the part that is in the full focus of consciousness or is readily available to such consciousness, to think of a preconscious part that is ordinarily not in the full focus of consciousness but can be made so with little effort, and a Subconscious subsystem that is ordinarily completely cut off from conscious awareness even though special techniques, such as psychoanalytic ones, give inferential information about it. I have followed the general psychoanalytic conventions (1) of showing the Subconscious as the largest part of the mind, to indicate that the largest portion of experience and behavior is probably governed by subconscious forces we are not aware of, and (2) of showing the conscious and preconscious parts of the mind as about equal in size. The barrier between conscious and preconscious has many "holes" in it while the Subconscious is relatively inaccessible. For example, if you dislike someone and I ask you to think about why you dislike him, a little thought may show that the reasons behind your immediate dislike result from a synthesis of the person's appearance and some unpleasant experiences you previously have had with people of that appearance. These reasons might actually be based on deeply buried subconscious feelings that all people of the same sex are rivals for mother's affection, things you ordinarily cannot become aware of without special therapeutic techniques.
Preconscious and subconscious contents may be more or less readily available in a d-ASC, depending on the d-ASC. In d-ASC 1 in Figure 8-2, more other mind and preconscious material are directly in consciousness and less are in the Subconscious subsystem. This, incidentally, is one of the danger of experiencing a d-ASC: a person may be overwhelmed by emotionally charged material, normally subconscious, that he is not ready to handle. This can happen with marijuana intoxication or other psychedelic-drug-induced states, as well as with meditative states or hypnosis. In all these states things that are ordinarily preconscious or subconscious may become conscious.
D-ASC 2 illustrates the kind of state in which things that are ordinarily conscious may become preconscious or subconscious. Certain drug-induced states or other d-ASCs that tend toward stupor might fit in this category, where consciousness feels quite restricted and dull, even though the subject's behavior suggests that previously conscious material is still affecting him. The alcoholic blackout state is interesting in this context, for the person seems to behave "normally" in many ways, indicating that much ordinarily conscious knowledge is still present, even though this is a blackout in terms of later recall.
D-ASC 3 represents various d-ASCs in which much subconscious material might become preconscious: it will not necessarily well up by itself, but it is much more readily available than ordinarily. Thus the potential for exploring the mind is greater, but effort must still be exerted. Marijuana intoxication can do this.
In terms of overall system functioning, I have shown a direct information flow arrow from Input-Processing to the Subconscious, and a feedback control arrow from the Subconscious to Input-Processing. Processed input information may reach the Subconscious and have effects even when it does not reach awareness. To use again the example of scanning the crowd, even though you are consciously looking for your friend's face, the impact of another face may trigger subconscious processes because of resemblance to someone emotionally meaningful to you, and may produce later effects on you even though you were not consciously aware of seeing that particular person.
The feedback control arrow from Subconscious to Input-Processing indicates that the Subconscious subsystem may have a major control over perception. Our likes and dislikes, needs and fears, can affect what we see. This kind of selectivity in perception is discussed in relation to the Input-Processing subsystem. I bring it up here to indicate a distinction between relatively permanent, learned selectivities of perception that are inherent in Input-Processing itself, such as ability to recognize words, and selectivities that are more dependent on the current emotional state of the Subconscious subsystem, and so may show more variation from time to time. For example, we have many permanent learnings that are part of Input-Processing and that enable us to distinguish men from women at a glance. But we have sexual needs that peak from time to time, and these may be partially or wholly in the Subconscious subsystem because of cultural repressive pressures. As these repressed needs vary, they affect Input-Processing and change our current perceptions of people of the opposite sex: they can become much more attractive when we are aroused. We should also briefly note the possibility of the activation of archetypes from the Collective Unconscious during d-ASCs. The terms archetypes and Collective Unconscious are used in Carl Jung's sense. The Collective Unconscious refers to a large body of biologically inherited psychological structures,, most of which remains latent human potentials. Particular structures are archetypes, innate patterns that can emerge and dominate consciousness because of the high psychic energy residing in them if the right stimuli for activation occur. Myths of heroic quests, demons, gods, energies, God, Christ, are held by Jung to be particular archetypes from the Collective Unconscious, which express themselves at various times in human history. It would take far too much space here to give them adequate consideration; the interested reader should refer to the collected works of Carl Jung. It should be noted, however, that some d-ASCs frequently facilitate the emergence of archetypes.
