What a mess. That’ll teach me to write while hiking.
Here’s the edit:
The question of whether and to what extent there is awareness in comotose patients or those in non-rem sleep has not been settled. I would argue that there is a form of implicit consciousness , but it is so rudimentary in relation to what we typically demand of the term ‘conscious’ that we end up concluding that a complete lack of awareness is involved.
I think the issue of blindsight is a good example:
Laura Chivers writes 'Blindsight is seen clinically as a contrast between a lack of declarative knowledge about a stimulus and a high rate of correct answers to questions about the stimulus . People suffering from blindsight claim to see nothing, and are therefore unable to reach spontaneously for stimuli, cannot decide whether or not stimuli are present, and do not know what objects look like. In this sense, they are blind. However, they are able to give correct answers when asked to decide between given alternatives. Studies done with subjects who exhibit blindsight have shown that they are able to guess reliably only about certain features of stimuli having to do with motion, location and direction of stimuli. They are also able to discriminate simple forms, and can shape their hands in a way appropriate to grasping the object when asked to try. Some may show color discrimination as well . Subjects also show visual capacities, including reflexes (e.g. the pupil reacts to changes in light), implicit reactions and voluntary responses.
People suffering from blindsight are not "blind" because their eyes do not function. Rather they suffer from cortical blindness. People suffering from cortical blindness receive sensory information but do not process it correctly, usually due to damage in some part of the brain. The damage in blindsight patients has been shown to be in the striate cortex, which is part of the visual cortex. The striate cortex is often called the primary visual cortex , and is thought to be the primary locus of visual processing . Destruction or disconnection of the striate cortex produces a scotoma, or a region of blindness, in the part of the visual field that maps to the damaged area of the cortex . Depending on the extent of the lesion, vision can be absent in anywhere between a very small section of stimulus field and the entire field . The person is unable to process the sensory input to the striate cortex, and does not recognize having seen the object. '
Cognitive theorists conclude from clinical examples of blindsight that consciousness is only a part of what goes on in the brain, and that consciousness is not needed for behavior. To argue that blindsightedness is not an example of unconscious processing (experience occuring in parallel with, but independent of conscious awareness) requires a new and different sensitivity to content of experience, and to the understanding of awareness. If there is no 'feeling of seeing' in blindsightedness, as is claimed, then there is feeling of a different sort, a quality of meaning that is overlooked by contemporary approaches to cognition and affect because of its subtlety. Familiarization with Gendlin's focusing techniques is one way to develop sensitivity to what for most is a world they have never articulated. This is the important point; phenomena such as blindsightedness evince not unconscious but inarticulate experience. One would need , of course, to analyze the aspects of the experience in blindsightedness. One has before one a task involving an intention to see, which implies the involvement of a certain concept of vision that the perceiver expects to encounter.
If the claim for blindsightedness were simply that this experience involves a different aspect of what is involved in seeing than one normally expects of a visual situation, (for instance, if one expects contrast, color, perspective, one gets instead a vague or incipient meaning that is not recognizable as seeing even though it in fact is normally part of all visual experiences), then I would be in agreement. If, however, the claim is that whatever meaning or information is prompting the blindsighted behavior is independent of the conscious experience(conscious and unconscious events as independent, parallel meanings), then I disagree. My claim is that the experience mistakenly called blindsight is an incipient or intuitive feel that is consciously, intentionally-metaphorically continuous with the ongoing flow of awareness. Blindsightedness is not an illustration of the partial independence of psychological subsystems, but of the fact that the most primordial 'unit' of awareness is something other than , and more subtle, than either contentful cognitive or empty affective identities. Just because something is not articulated does not mean that it is not fully experienced.
The nature of the experience in blindsightedness would not be unlike the way that the 'same' object that one observes over the course of a few seconds or minutes continues to be the 'same' differently even though it is typically reported to be self-identical over that interval. A changing sense of a thing is not noticed until it becomes an intense affect, and then it is ossified as an abstract 'state'. From the perspective of awareness, cognitivism seems to order experiences hierarchically, privileging what is considered conceptual content over affectivity by virtue of its supposed repeatability, and valuing both of these over other events that are labeled unconscious because they are assumed to be devoid of any conscious content. Blindsight involves a barely discernable shift of sense in an ongoing experience of regularity. There would be not only blindsight, but deaf-hearing, numb-tactility and non-conceptual conceptuality. The test of consciousness of a thing:'Can one see that thing emerging from a field of perceived sameness?' is wrongheaded because it doesn't recognize that the field of supposed sameness is already a movement of changing meanings. The conscious-unconscious binary should be re-configured as a spectrum of meaningfulness)
