Consciousness Goes Deeper Than You Think (scientificamerican.com)

An anonymous reader shares a post from Scientific American, written by Bernardo Kastrup: 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. Yet, it is hard to think that there is nothing it feels like to be a newborn. 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, insisted that "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.

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.

      You're being too black and white when you say "babies are not conscious" (because of an inability to recognise themselves in a mirror). Consciousness is a spectrum of response involving reaction to a stimulus. At the extreme low end you could argue a simple automated greenhouse window opener was conscious - it reacts to the stimulus (temperature) by taking an action to control something (opening the window). Plankton, and plants, are a bit more conscious. Collectives (as in ants in an anthill or neurons in a brain) operate at a higher level of consciousness again. Higher animals reach such a degree of consciousness that we regard them as "sentient" (but while we might be able to define sentience, it seems impossible to sentience (or lack of) in every case. To a very few animals (humans, a few higher apes, arguably some birds) we ascribe the highest level of all: sapience.

      Babies are actually quite a good example because they progress through all these stages. At fertilisation they're barely conscious: I'm not sure if there are any stimuli that a fertilised egg responds to in order to attract it to the wall of the uterus or if it drifts there. However as the embryo develops it definitely begins to respond to stimuli and therefore "becomes conscious". Through gestation the degree of consciousness increases: by around week 24 it reaches the level where if you poke a baby through the mother's belly it will push back. My wife has noticed that if she sits in certain positions our baby gives her a good hard kick until she moves, in a response to feeling uncomfortable. That seems to pass the bar for sentience, given how it's applied to other animals. Newborns can already react to hot, cold, hunger, tiredness, wetness / poo-coveredness. At some point the baby becomes sapient: I expect that's normally some point in the first year or couple of years after birth.

    I'm an engineer. i can't not experiment with my kids.

    I watched my oldest daughter in "4d ultrasound" perform self-soothing by caressing her own cheek. After she was born and experiencing "the end of her previous universe", in the first week of life, I caressed the cheek the way she had, and she responded powerfully. It amazed her. It strongly supported bonding. Her eyes got wide, her pupils dilated, and she took a deep breath of surprise. She then leaned into it.

    I played pat-a-cake with my daughter when she was in the womb. I would feel my wife's belly for her hands, and then I would push in. When I pushed in once, she would push out once. When I pushed in twice, she would push out twice. There was a concept of time-series, number, or symmetry.

    I observed several signficant transitions (jumps) in capability to interact with the "universe", but her "her-ness", her personality, her character, and her mental acuity were consistent. The leaps were more about costs per level of interaction, but not the fundamentals.

    I taught her tongue-signs at 2 weeks old. She can nurse, which means she had basic control of her tongue and lips. It ended up being an indicator of if she had will, opinion, or particular desire long before she could hold her head up, and long long before should could crawl, walk, or drive the complexities of the human vocal apparatus. She was clearly able to indicate her desire for 1) a binkie, or 2) a bottle. There were times I tested this, and I gave her one insead of the other. I tried both ways, and each time, she would spit the undesired object out, and repeat the sign.

    My bottom line: she was always conscious. It was not that her consciousness changed, but the physical architecture, in terms of muscle control, methods of communication, energy levels, and emotionally coming to terms with the end of the world she had formerly known that had been the changes.

    I think people who do not rigorously watch, and experiment (with purpose of learning, such that learning informs empowerment of the child) have to question whether they are conscious after they are born.

    I suspect that evil people would use it as a way to create a new class of murder - if their mind is numbed just a little, then they aren't really conscious when they are killed, and it isn't "cruel or unusual punishment". Whether they apply this to execution of prisoners, to the enemy combatant on the battlefield, or to euthanasia of newborns, I think it is dangerous to provide answers to badly asked questions. I have a substantial problem with the false assumptions behind the question of when, after birth, conscious starts. My clear observations strongly support that it existed before birth, and doesn't go away.

    To some degree, this just sounds like playing word games, and coming up with new terms to sound like you've discovered something. Traditionally, there has been a distinction between sentience and consciousness. If you just want to say that babies feel and experience things, that's sentience and not necessarily consciousness. We can redefine the word "consciousness" to mean "sentience" and invent the word "meta-consciousness" to mean "consciousness", but you haven't really accomplished anything.

    The concept of consciousness has been explored and modified over the past few thousand years (at least, we have records of people writing about it that far back), and it's fair to want to modify it some more. However, I think there's been a general view for a while that newborns are sentient but don't have much consciousness, and then we develop consciousness as we grow up. There seem to be developmental periods where our brains become capable of understanding certain things, and debatably those constitute different levels of consciousness and awareness, but again, that debate will be as much about what terms you want to use as it will be about our actual understanding of human development.

Clearly there are gradients involved. How narrowly do we want to define this? A slime mold reacts to various stimuli, and so do we. On the other hand, most higher orders of life have the ability to process more complex stimuli and have a richer choice of decisions in most scenarios. But I've seen cats make strategic decisions when playing (as well as wild animals doing the same). Is a cat as conscious as an adult human? Probably not. But I submit that a cat is also more conscious than a typical lizard, which is more conscious than a typical insect, which is more conscious than a typical microbial colony.

      But if you think about it, consciousness has to be an emergent property partially related to complexity. We are aggregates of cells, none of which is conscious on its own; but then how does one determine how many cells are required to begin to define something as conscious? Until consciousness is far more clearly defined, a lot of the argument is going to be over the definition.
