Nella descrizione delle componenti di sistema degli stati di coscienza Tart, dopo aver introdotto le prime due - consapevolezza ed energia - descrive la terza: le strutture.

Structures

The mind, from which consciousness arises, consists of myriad structures. A psychological structure refers to a relatively stable organization of component parts that perform one or more related psychological functions. We infer (from outside) the existence of a particular structure by observing that a certain kind of input information reliably results in specific transformed output information under typical conditions. For example, we ask someone, "How much is fourteen divided by seven?" and he answers, "Two." After repeating this process, with variations, we infer the existence of a special structure or related set of structures we can call arithmetical skills. Experientially, we infer (from inside) the existence of a particular structure when, given certain classes experienced input information, we experience certain transformed classes of output/response information. Thus, when I overhear the question about fourteen divided by seven and observe that some part of me automatically responds with the correct answer, I infer an arithmetical skills structure as part of my own mind. We hypothesize that structures generally continue to exist even when they are not active, since they operate again when appropriate activating information is present. I again know that fourteen divided by seven equals two, even though I stopped thinking about it for a while. The emphasis here is on the structure forming something that has a recognizable shape, pattern, function, and process that endure over time. Ordinarily we are interested in the structure's overall properties as a complete structure, as a structured system, rather than in the workings of its component parts. Insofar as any structure can be broken down into substructures and sub-substructures, finer analyses are possible ad infinitum. The arithmetical skill structure can be broken down into adding, subtracting, multiplying, or dividing substructures. Such microscopic analyses, however, may not always be relevant to an understanding of the properties of the overall system, such as the state of consciousness, that one is working with. the most obvious thing that characterizes an automobile as a system is its ability to move passengers along roads at high speed; a metallurgical analyses of its spark plugs is not relevant to an understanding of its primary functioning and nature. Our concern, then, is with the psychological structures that show functions useful to our understanding of consciousness. Such structures can be given names—sexual needs, social coping mechanisms, language abilities. Note that some structures may be so complex that we are unable to recognize them as structures. We see only component parts and never understand how they all work together. A psychological structure may vary in the intensity and/or the quality of its activity, both overall and in terms of its component parts, but still retain its basic patterns (gestalt qualities) and so remain recognizably the same. A car is usefully referred to as a car whether it is moving at five or twenty-five miles an hour, whether it is red or blue, whether the original spark plugs have been replaced by spark plugs of a different brand. We anticipate an understanding of a state of consciousness as a system here. Some structures are essentially permanent. The important aspects of their functioning cannot be modified in any significant way; they are biological/physiological givens. They are the hardware of our mental system. To use an analogy from computer programming, they are fixed programs, functions built into the machinery of the nervous system. Some structures are mainly or totally given by an individual's particular developmental history; they are created by, programmed by, learning, conditioning, and enculturation processes that the individual undergoes. This is the software of the human biocomputer. Because of the immense programmability of human beings, most of the structures that interest us, that we consider particularly human, are in this software category. Permanent structures create limits on, and add qualities to, what can be done with programmable structures: the hardware puts some constraints on what the software can be. The physiological parameters constituting a human being place some limits on his particular mental experience and his possible range of programming. Our interest in relatively permanent structures, one that are around long enough for us conveniently to observe, experience and study. But all the theoretical ideas in this book should be applicable to structures that are not long-lasting, even though investigation may be more difficult. Structure, for the outside investigator, are hypothesized explanatory entities based on experiential, behavioral, or psychological data. They are also hypothesized explanatory concepts for each of us in looking at his own experience: I know that fourteen divided by two equals seven, but I do not experience the arithmetical skills structure directly; I only know that when I need that kind of knowledge, it appears and functions. Since I need not hold on consciously to that knowledge all the time, I readily believe or hypothesize that it is stored in some kind of structure, someplace "in" my mind.
