On Scientific American: Consciousness Goes Deeper Than You Think

Quote:An article on the neuroscience of infant consciousness, which attracted some interest a few years ago, asked: “When does your baby become conscious?” The premise, of course, was that babies aren’t born conscious but, instead, develop consciousness at some point. (According to the article, it is about five months of age). Yet, it is hard to think that there is nothing it feels like to be a newborn.[url=https://blogs.scientificamerican.com/observations/consciousness-goes-deeper-than-you-think/]
Newborns clearly seem to experience their own bodies, environment, the presence of their parents, etcetera—albeit in an unreflective, present-oriented manner. And if it always feels like something to be a baby, then babies don’t become conscious. Instead, they are conscious from the get-go.
The problem is that, somewhat alarmingly, the word “consciousness” is often used in the literature as if it entailed or implied more than just the qualities of experience. Dijksterhuis and Nordgren, for instance, insistedthat “it is very important to realize that attention is the key to distinguish between unconscious thought and conscious thought. Conscious thought is thought with attention.” This implies that if a thought escapes attention, then it is unconscious. But is the mere lack of attention enough to assert that a mental process lacks the qualities of experience? Couldn’t a process that escapes the focus of attention still feel like something?
Consider your breathing right now: the sensation of air flowing through your nostrils, the movements of your diaphragm, etcetera. Were you not experiencing these sensations a moment ago, before I directed your attention to them? Or were you just unaware that you were experiencing them all along? By directing your attention to these sensations, did I make them conscious or did I simply cause you to experience the extra quality of knowing that the sensations were conscious?
Indeed, Jonathan Schooler has established a clear distinction between conscious and meta-conscious processes. Whereas both types entail the qualities of experience, meta-conscious processes also entail what he called re-representation. “Periodically attention is directed towards explicitly assessing the contents of experience. The resulting meta-consciousness involves an explicit re-representation of consciousness in which one interprets, describes or otherwise characterizes the state of one’s mind.
So where attention plays an important role is in re-representation; that is, the conscious knowledge of an experience, which underlies introspection. Subjects cannot report—not even to themselves—experiences that aren’t re-represented. Nothing, however, stops conscious experience from occurring without re-representation: Dreams, for instance, have been shown to lack re-representation, despite the undeniable fact they are experienced in consciousness. This gap between reportability and the contents of consciousness has motivated the emergence of so-called “no-report paradigms” in the modern neuroscience of consciousness.
Clearly, the assumption that consciousness is limited to re-represented mental contents under the focus of attention mistakenly conflates meta-consciousness with consciousness proper. Yet, this conflation is disturbingly widespread. Consider Axel Cleeremans’s words: “Awareness…always seems to minimally entail the ability of knowing thatone knows. This ability, after all, forms the basis for the verbal reports we take to be the most direct indication of awareness. And when we observe the absence of such ability to report on the knowledge involved in our decisions, we rightfully conclude the decision was based on unconscious knowledge.”
'Historically, we may regard materialism as a system of dogma set up to combat orthodox dogma...Accordingly we find that, as ancient orthodoxies disintegrate, materialism more and more gives way to scepticism.'
