I've taken a lot of psychedelics, and I don't think it's at all similar to dreaming. — Metaphysician Undercover
I can agree that this prediction process, is an important aspect of consciousness, but I do not really agree with the verification aspect you are suggesting. — Metaphysician Undercover
I think you have this reversed, the predictions require sense perception as the basis of the prediction, what the prediction is derived from. To know what comes next requires sensing what just happened. Therefore, when sense perception is not there, in the dream, predictions simply cannot be made. This implies that what is produced in the dream state is something other than predictions. — Metaphysician Undercover
In a dream, all of the so-called "conditions" are created by the dreaming mind. Therefore it is the brain generating the conditions directly, and the person dreaming believes them regardless of how scrambled they are. Verification is irrelevant, unless perhaps the person is lucid dreaming and has purposedly forced the desire for verification to become part of the dream. — Metaphysician Undercover
You are neglecting the fact that a stream of sensory data is required to produce a prediction in the first place. And this is not available to the dreamer. Therefore the dream does not consist of predictions. — Metaphysician Undercover
As explained above, dreams are not predictions, and verification is irrelevant. So I think the rest of your post is derived from false premises. — Metaphysician Undercover
In neuroscience, predictive coding (also known as predictive processing) is a theory of brain function which postulates that the brain is constantly generating and updating a "mental model" of the environment. According to the theory, such a mental model is used to predict input signals from the senses that are then compared with the actual input signals from those senses. Predictive coding is member of a wider set of theories that follow the Bayesian brain hypothesis. — Wiki
Aren't the perceptual functions and imaginative functions pretty much the same though? — Metaphysician Undercover
I don't think that the conscious mind has such a causal power at all. The conscious mind owes all its experiences to the subconscious mind. It has very limited memory so-called working memory. It can only work on a very limited scope because it does not have access to the memories that are stored in the subconscious mind. It is also not necessary to have access to all memory when it comes to a topic that is the subject of focus. When the conscious mind focuses on a topic it requires the related knowledge of what is experienced in the past. This knowledge is registered in the subconscious mind's memory. The conscious mind does not have direct access to this memory and this memory is delivered to the conscious mind by the subconscious mind.I think I explained this already. The conscious part of your mind must have the ability to cause the subconscious part to present things to it in a sensible, rational way, or else the subconscious would be doing it in a random way like when we dream. So it is the ability to think rationally, and in a more general sense the ability to stay awake, which is the conscious mind exercising causal power over the subconscious.
For instance, you say that what is learned is registered in the subconscious. Let's call this a memory, and we'll say that the subconscious has a whole lot of memories. When the conscious mind thinks in a rational way, it needs to recall memories from the subconscious which it uses in that activity. Therefore it must have causal power over the subconscious, to cause the subconscious to present these memories to it in a way which makes sense. If the conscious did not have causal power over the subconscious, the subconscious would be presenting things in a random way, like in a dream. — Metaphysician Undercover
Do you have access to all your memory at once? Sure not. A specific memory just pops into your conscious mind and this is due to the subconscious mind delivering this memory to you. Anyhow I was commenting on people who have memories of their past lives. I was arguing that such memory is not stored in the brain since such individuals do not own the same body. So I don't understand how your comment is related to what I was arguing.I consider "memorizing" to be an activity of the conscious mind, not the subconscious. It is a repetitive practise of recollection. — Metaphysician Undercover
That is not what I was saying. I said that the similarities are in how it disconnects or scramble the verification process in the brain. Making the brain trying to predict something it does not get a verification to ground the predictions into an easily navigational space. — Christoffer
It's part of predictive coding theory which is the current dominant theory in the science of consciousness. If you don't agree, you need to provide something else that explains how the predictions are structured into a consistent experience. — Christoffer
Why are you concluding it to be something else rather than unbound predictions based on the flow of memories? As I mentioned, in predictive coding, it's already stated that our sensory data grounds the predictive process, so you're simply wrong against the dominating theory. — Christoffer
Short term memory is a form of RAM memory bridge that is constantly feeding experiences into long term memory to restructure it for better predictions. — Christoffer
When we dream, it's our experience of this stream of sequences being consolidated into a restructuring of our predictive model. We experience our brain trying to predict reality based on the stream of sequences from our short term memory, but there's no sensory perception to ground that stream of experiences that's flushed out of our short term memory. So it predicts without solid footing and we experience this interplay between old and new memories as they're being consolidated into long term memories to later be used for future predictions when we wake up. — Christoffer
What is this "dreaming mind"? You're not describing an actual process here, just referring to some elusive conjecture called "the dreaming mind". — Christoffer
Our awareness of what is real and what is not has nothing to do with the prediction and verification process. — Christoffer
If your read what I'm saying, that's what I'm saying. Even though you're a bit off on the role of the sensory data (the sum experience of interplay between long term memory predictions and sensory data verifying it - is the thing that feeds the long term memory with alterations for how to predict the next moment), the concept is that without the sensory data to ground the prediction model, it can only use the short term memory's stored sequences from the last awaken state as its verification, which scrambles the experience as it's not raw data constantly grounding the predictions. — Christoffer
But this wouldn't really account for the behavior of dreams combining experiences of both present day and long term stored memories. That there's an interplay between new experiences we just had and memories we might consciously have forgotten about. The interplay between them is the brain looking for connections, neural paths that combine into a solid prediction before the next day. — Christoffer
You essentially counter-argue with the same conclusion I've already made. Which implies you don't really understand what I'm talking about. And you're not really explaining anything, you're saying an opinion and then use that to form a conclusion. You need actual science and theories behind what you conclude, not just what you agree or don't agree with, otherwise it's just opiniated conjecture. — Christoffer
I think you need to read up on predictive coding and what that implies for this topic. Otherwise you're getting lost in what I'm talking about. — Christoffer
I don't think that the conscious mind has such a causal power at all. The conscious mind owes all its experiences to the subconscious mind. — MoK
The difference is that when a person is awake, his conscious mind experiences a simulation of reality that is the result of sensory inputs -- he also experiences thoughts, feelings, etc., whereas when he is asleep, he only experiences a simulation constructed by the subconscious mind.Then how would you account for the difference between awake experiences, and dream experiences? — Metaphysician Undercover
The difference between the two is that the conscious mind can only function properly when a person is awake, while the subconscious mind is always active. The conscious mind is also responsible for creating new thoughts based on what it perceives from the subconscious mind. These new thoughts then are registered in the subconscious mind's memory for further analysis in the future.If each is the subconscious presenting experience to the conscious, in the exact same way, why is there a difference between the two? — Metaphysician Undercover
Correct.We can't simply say that the senses are active in one case, and inactive in the other, because we need to account for whatever it is which activates the senses. — Metaphysician Undercover
Becoming awake is partly due to senses (from Google): People wake up at a certain time in the morning primarily due to their "circadian rhythm," which is essentially the body's internal clock located in the brain's hypothalamus, that regulates sleep-wake cycles by releasing hormones like melatonin based on light exposure, causing us to feel sleepy at night and alert in the morning when light hits our eyes; essentially signaling the body to wake up.The senses do not activate themselves. — Metaphysician Undercover
As I mentioned, the subconscious mind is always active otherwise it could not construct dreams.Nor does it appear like the subconscious activates the senses, or else they would be activated in dreams. — Metaphysician Undercover
Correct.But in most cases, when a sense is activated (a loud sound for instance), it coincides with waking up. — Metaphysician Undercover
The difference is that when a person is awake, his conscious mind experiences a simulation of reality that is the result of sensory inputs -- he also experiences thoughts, feelings, etc., whereas when he is asleep, he only experiences a simulation constructed by the subconscious mind. — MoK

I should have said: The conscious mind owes most of its experiences to the subconscious mind". This is now an accurate statement.This does not address the problem. You said: "The conscious mind owes all its experiences to the subconscious mind". This implies that in both dreaming and awake, the consciousness "only experiences a simulation constructed by the subconscious mind". — Metaphysician Undercover
I don't know the purpose of dreams. There is however a collaboration between the conscious mind and the subconscious mind and that is necessary. The conscious mind is fast but it has access to its memory which is very limited. The conscious mind works on its memory and can produce a thought for example if that is possible. When the thought is produced as a result of the work of the conscious mind then there is nothing to work on anymore so the conscious mind stays silent unless it receives the new input from the subconscious mind.Now you have simply asserted that in the awake condition the simulation is the result of sensory inputs, thoughts and feelings. But these are things experienced in the consciousness. And, you have in no way answered my question, which was how do you account for this difference. If the conscious mind owes all of its experiences to the subconscious, why, and how, would the subconscious be creating these two very distinct types of experience for the consciousness, the asleep experience, and the awake experience? — Metaphysician Undercover
Correct. Please see my first comment and thanks for your comment.You are being inconsistent. If the consciousness owes all of its experience to the subconscious, as you claim, then it is inconsistent to say that the conscious mind can create something itself (new thoughts). — Metaphysician Undercover
Correct. The conscious mind has the capacity to create thoughts when the person is awake. The subconscious mind can also create thought and it is intelligent as well but the most of thoughts are created by the conscious mind. The subconscious mind is intelligent because it knows what sort of input the conscious mind requires when the conscious mind focuses on a topic. The subconscious mind can create thoughts as well. It occurred to me on several occasions in my life that I was thinking about something very hard without reaching a conclusion. An idea then just popped up into my conscious mind when I was resting and the idea was very enlightening for what I was thinking. I think that such ideas are created by the subconscious mind.And if we allow that the conscious mind has such a creative capacity, then we need principles to distinguish between what is created by the conscious and what is created by the subconscious. — Metaphysician Undercover
I think I have discussed the responsibilities of the conscious and subconscious mind to a good extent by now.Without such principles, one could argue, as Cartesian skeptics do, that everything supposedly presented from the subconscious, along with sense data, are a creation of the conscious. — Metaphysician Undercover
I think it is both circadian rhythm and senses that are involved when we become awake.I don't understand what you are saying. You explain the circadian rhythm as something completely independent from the senses, yet you claim that being awake is partly due to the senses. — Metaphysician Undercover
Because the conscious mind needs to rest for a period of time, what we call sleeping.Again, this doesn't address the issue, which is the following. If the subconscious is always active, therefore always providing something for the consciousness, why would it at sometimes provide sense data, and at other times not? — Metaphysician Undercover
The conscious mind has control over things, such as the creation of thoughts, decisions, etc. when the person is awake.If things are as you say, that the subconscious is always in complete control over what the consciousness receives, and the consciousness has no causal influence over this, then how does the subconscious turn off and on the sense input, when it appears to be the opposite, because it is actually the consciousness which goes to sleep and wakes up? — Metaphysician Undercover
The conscious mind does not receive any sense data when the person is asleep. It however receives hallucinations so-called dreams when the person is asleep. The situation is different when the person is awake.Since the consciousness is what goes to sleep and wakes up, it appears obvious that the consciousness itself turns off and on the sense data. — Metaphysician Undercover
I explained to you why "verification" is irrelevant. — Metaphysician Undercover
No, I do not have to provide something else. I demonstrated logically, from sound premises, why your "predictive coding theory" is false in its application to dreams. — Metaphysician Undercover
Unless there is something experienced as "the past", there is no grounds for any prediction of "the future". Anything predicted of the future must be derived from something already experienced of the past. When you say that predictions are based on the flow of memories you admit to this. So unless you provide another source for memories, you have not any principles to deny that prediction is based in, and requires sensation. — Metaphysician Undercover
You have provided no principles to support this speculation that the purpose of this "memory bridge" is "better predictions". You simply assume "prediction" as your principle, and you see that this "bridge" could produce better predictions, so you conclude therefore it's purpose is better predictions. That is not a valid conclusion. — Metaphysician Undercover
This makes no sense at all. If there is no sensory perception then there is no short term memory. — Metaphysician Undercover
The "dreaming mind" is a mind which is dreaming. Have you never actually had a dream before? If you have, then I'm sure you've experienced your mind to be dreaming, and you know exactly what I mean by "the dreaming mind". — Metaphysician Undercover
Then why present me with this theory of prediction and verification, if it has no bearing on what is expressed in the op? Are you admitting that your prediction theory is irrelevant here? — Metaphysician Undercover
This is clear evidence that your prediction model is incapable of accurately representing the reality of the situation. — Metaphysician Undercover
First, there is no separation between sensory data and short term memory, as. Sensory data is short term memory, as the thing sensed is in the past by the time sensation of it is recognized. — Metaphysician Undercover
So, without sensory data (short term memory) the mind must rely on long term memory. — Metaphysician Undercover
This is why dreams often consist of long ago acquaintances. — Metaphysician Undercover
Finally, when we visit long term memories we are reflecting, or trying to learn some general principles, we are not predicting. Predicting is when we apply such principles. — Metaphysician Undercover
So the dreaming mind, which is drawing on the long term memory, because the short term is incapacitated by sleep — Metaphysician Undercover
It has been widely accepted that sleep must support the formation of long-term memory, and generally increasing previous learning and experiences recalls. — Wiki
Let me present you with an example, my childhood recurring dream of falling. — Metaphysician Undercover
My dreams would progress through many stages, until they'd reach the point when I am falling. Then, with the "prediction" of hitting the ground, I would wake up instantaneously. Waking up was simultaneous with predicting. So we can see that there was no predicting within the dream itself, and the occurrence of prediction coincided with waking up, as being a feature of the mind in its awake condition, not its dreaming condition. — Metaphysician Undercover
I do not think that this is representative of common dreaming at all. My dreams practically never have present day experiences within them. They are almost always completely removed and distinct from what I was doing that day, having no relationship to that whatsoever. — Metaphysician Undercover
However, for the reason explained, and the logical argument I presented — Metaphysician Undercover
I believe that Predictive coding is not applicable to the dreaming mind (activity of a mind in the dreaming condition). — Metaphysician Undercover
I think that what is misleading you is that predictive coding is somewhat applicable to a mind under the influence of hallucinogens, and you seem to think that hallucinating is the same as dreaming. — Metaphysician Undercover
I should have said: The conscious mind owes most of its experiences to the subconscious mind". This is now an accurate statement. — MoK
The subconscious mind is intelligent because it knows what sort of input the conscious mind requires when the conscious mind focuses on a topic. — MoK
The subconscious mind can create thoughts as well. It occurred to me on several occasions in my life that I was thinking about something very hard without reaching a conclusion. — MoK
The conscious mind does not receive any sense data when the person is asleep. It however receives hallucinations so-called dreams when the person is asleep. The situation is different when the person is awake. — MoK
But you provide no support for that explanation. I'm referring to predictive coding which has experimental verification. — Christoffer
"My" predictive coding theory? Sorry, but if you're to reject an actual scientific theory that has experimental proof behind it, then I'm sorry, but you're not operating on a level enough for critical thinking around this subject. — Christoffer
If you are to object to it, provide references to other experimental data and theories that criticize it. There are some that do this, all thought today they're in a minority due to the experimental evidence backing predictive coding. — Christoffer
Predictions are based on past experiences, that's what I'm saying, but these predictions are similar to generative computation in which the generated predictions are chaotic and filled with errors. Sense data grounds this and verifies it in real-time. — Christoffer
No, you are using "the dreaming mind" as a elemental object in your rhetoric as if it was an object in support of your conclusions. The "dreaming mind" means nothing without the facts on how it operates and function and why we dream in the first place. I'm speaking of the mechanics behind it, which then informs the reason why we experience the belief in our dreams as they happen. You can't just say "the dreaming mind" as some illusive part of your argument and ignore the reasons why we dream. — Christoffer
Because it is part of understanding why it happens. When sensory verification gets cut off, people still believe the reality that is scrambled in their experience. Because there's no other system in the mind that operates as a form of separate perception of the experience able to deduce its validity or not, it's a holistic system in which the distortion of reality and the belief in that reality depends on how well the whole system is able to operate. A gradual process that at a certain point of distortion, distorts the whole process and in turn the ability to discern what's real and what's not based on our experience of verified reality.
It's hard to explain this when you seem to get lost in even the most basic explanation. — Christoffer
For the second time, it's not "my" theory, it's a scientific theory with experimental evidence. — Christoffer
While this process is constantly happening, it's when we sleep that we consolidate and flush our short term memory and produce stronger neurological pathways. — Christoffer
Predictive operation happens through the interplay between short term memory, long term memory and sense verification. Cutting out one of these out or distort it, will scramble the entire process, making the experience jarring for us, as we experience in hallucinations and dreams. — Christoffer
You do not visit long term memory. It's not a damn book store. — Christoffer
Wrong, memory consolidation and the processes of the mind are proven to be "on" even when we sleep. You are denying the science here, making shit up to support your own ideas. — Christoffer
Your experience is not evidence and proof of what you say. — Christoffer
Predictive coding at its core is not about you "consciously" predicting anything. What does this have to do with predictive coding? You're just confused. I recommend you read up on what you're arguing against before making up odd interpretations of what the prediction aspect is about. — Christoffer
Why don't you read up on actual sleep science and neuroscience instead? — Christoffer
Your belief is irrelevant when the science says otherwise. — Christoffer
No, as I repeatably have been saying, hallucinations and being under the influence, inflicts a disruption to the interplay in predictive coding, primarily sense perception verification, which makes our brain predicting unreliable and producing distortions to our experience. — Christoffer
Fundamentally, you ignore the science behind all of this. — Christoffer
Drawing on these, forming a holistic theory of what happens when the chain of operation is disrupted, either through chemical psychedelics and when we sleep. — Christoffer
I provided you a very good argument demonstrating that dreaming cannot possibly be a predictive process. This leaves verification, which is related to predictive process, as totally irrelevant. That was my support. — Metaphysician Undercover
So-called "scientific theory" is rejected when it is not consistent with empirical evidence. That is the nature of one form of critical thinking. — Metaphysician Undercover
I've provided you the argument which eliminates the possibility that dreaming is a predictive process. — Metaphysician Undercover
a "prediction" consists of extending the immediate past into the future, to predict what will happen. Without any sense data there is no immediate past upon which to base a prediction for the future, therefore prediction is impossible. A dream is not a predictive process. "Predictive process" theory applies only to a brain which is actively sensing — Metaphysician Undercover
Further, I provided personal evidence — Metaphysician Undercover
That is my "experimental data" — Metaphysician Undercover
It is you who is making "the dreaming mind" into an elemental object, through your false premise. You premise that thinking is fundamentally a predictive process, and then you view all mental activity from this perspective. This gives you a significantly biased perspective. — Metaphysician Undercover
Instead of viewing predictive capacity as a higher aspect proper only to a highly developed consciousness, with a highly developed intellectual capacity, you view predictive capacity as a fundamental aspect of any form of thinking. — Metaphysician Undercover
So when you look at the more base aspects of thinking, such as those demonstrated by dreaming, you improperly impose this highly developed aspect, predictive capacity, onto that base aspect, and conclude that the base aspect is carrying out the higher aspect to a lesser degree, which is chaotic and full of error. This robs you of the ability to properly understand the base capacity, for what it really is, and how it allowed for the development of the higher capacity, because all you can see is a lack of the higher capacity (chaotic and filled with errors), and you have no principles by which to understand what the base capacity really is. — Metaphysician Undercover
I agree that this is hard for you to explain to me. Your false premise makes "verification" irrelevant. — Metaphysician Undercover
It is your theory. You have adopted it, and support it. Therefore it is your theory, and it forms your bias, regardless of who invented it. — Metaphysician Undercover
This demonstrates clearly what your problem is. You characterize "the processes of the mind" as fundamentally predictive, and you take this as a primary premise. Then you admit evidence which demonstrates that the mind is active even when we are asleep. But instead of admitting the evidence which demonstrates that the activity while asleep is not predictive, thereby disproving your primary premise, you wrongly assert that the activity while one is asleep is predictive. — Metaphysician Undercover
That's what I'm doing, I'm claiming that your basic premise "thinking is a predictive process" is false. So you'll never get through to me by talking about verification, because I've already excluded verification as irrelevant by denying your basic premise. — Metaphysician Undercover
It is your theory. You have adopted it, and support it. Therefore it is your theory, and it forms your bias, regardless of who invented it. — Metaphysician Undercover
OK, let's look at this. Would you agree, that when we sleep, and we "consolidate and flush our short term memory and produce stronger neurological pathways", that this is not a predictive process? If so, then why would you think that dreaming, which is also what occurs when we sleep, is a predictive process? — Metaphysician Undercover
This is completely wrong, and misrepresentative. You are just making it up. — Metaphysician Undercover
If "predictive operation" requires three aspects, and one of them is removed, then we no longer have "predictive operation". That is simple logic. — Metaphysician Undercover
It appears like you are so wrapped up in your pseudo-science, and deceptive false premises — Metaphysician Undercover
When I want to think about something which occurred years ago, I "visit long term memory", just like if it was a conveniently located book store. — Metaphysician Undercover
I think it's you who needs to read up on "predictive coding". You are wrongly applying the science of the neurological activity which depends on sense perception (awake), to the neurological activity which occurs without sense perception (asleep). This has gotten you totally confused. — Metaphysician Undercover
...which postulates that the brain is constantly generating and updating a "mental model" of the environment. According to the theory, such a mental model is used to predict input signals from the senses that are then compared with the actual input signals from those senses. — Wiki
If experience is not evidence then you are not doing science. This is more evidence that what you present is pseudo-science. — Metaphysician Undercover
Personal experience is irrelevant to you, because you are a pseudo-scientist. A true scientist knows that verification relies on experience. — Metaphysician Undercover
Maybe we can get somewhere if you'll seriously consider this statement of yours. — Metaphysician Undercover
What I ignore is the pseudo-science which you are professing. — Metaphysician Undercover
I am waiting for you to respect the fact that when the disruption is complete, as in the case of sleeping, the operation, which is the predictive coding process, no longer occurs. Therefore we cannot apply predictive coding theory to the dreaming mind. — Metaphysician Undercover
I think the conscious mind and the subconscious mind collaborate. For example, without a conscious mind, no new thought is possible but new thought requires a constant exchange of information between the conscious mind and the subconscious mind. I think that even completing a sentence is not possible without this collaboration since the conscious mind has a very limited memory so-called working memory.Now, all you need to do is notice that the conscious mind has some causal power over the subconscious, and we'd be in agreement. From this agreement we could proceed to discuss the effect of this causal power, and the extent of it. Would you agree that what we call "will power" is an example of this causal power. — Metaphysician Undercover
I don't think that is the case. The subconscious mind is a part of the brain, that part is a neural net, therefore the subconscious mind is intelligent. I also think that all the memories stored in the subconscious mind are present to it at once otherwise we are dealing with a regress when we try to recall something.How do you know that this is not just an automatic type of action, like a computer? Maybe the conscious indicates to the subconscious what to do, and the subconscious does it, like a machine. — Metaphysician Undercover
The conscious mind's memory is very limited, so-called the working memory. From Google: "According to current research, the conscious mind's working memory size is generally considered to be around three to five items or "chunks" of information, meaning that you can actively hold and manipulate only a small amount of information in your conscious awareness at any given time." The rest of the memories are stored in the subconscious mind.You say that the conscious mind's access to memories is limited, and that's obvious from the fact that memory is not perfect, and degrades with time, but I think that this is generally a degradation of the subconscious part. — Metaphysician Undercover
All I can tell is that dream is constructed by the subconscious mind. It could be a supernatural phenomenon as well. Who knows!? Thinking to me, when we are awake is the byproduct of collaboration between the conscious mind and the subconscious mind as I illustrate above.This is obvious, in dreams, and that is the point of the op. It is the subconscious which creates those thoughts. And we must call them "thoughts", because they are not memories, but imaginative fictional experiences. But what I was arguing, is that in these instances where the subconscious is "thinking", without being directed by the conscious, the thoughts are very random and not logically consistent. — Metaphysician Undercover
An argument needs support in evidence, otherwise an argument is just an opinion. — Christoffer
You reject the actual science because it doesn't align with what you believe and therefore you believe that your own argument is more accurate than an argument based in the actual science. It's impossible to argue with someone who is so fundamentally entrenched in their own belief. — Christoffer
And what empirical evidence do you have that rejects predictive coding? — Christoffer
You don't understand what predictive coding is and how it works. You invent your own interpretation of it and then argue against it. — Christoffer
In neuroscience, predictive coding (also known as predictive processing) is a theory of brain function which postulates that the brain is constantly generating and updating a "mental model" of the environment. According to the theory, such a mental model is used to predict input signals from the senses that are then compared with the actual input signals from those senses. Predictive coding is member of a wider set of theories that follow the Bayesian brain hypothesis. — Wikipedia
What science are you drawing upon to make this counter-argument? — Christoffer
https://pubmed.ncbi.nlm.nih.gov/38097096/Predictive processing theories propose that these representations emerge from predicting or reconstructing sensory inputs. However, brains are known to generate virtual experiences, such as during imagination and dreaming, that go beyond previously experienced inputs. Here, we suggest that virtual experiences may be just as relevant as actual sensory inputs in shaping cortical representations.
Where's your foundation? What are the corner stones of your logic? — Christoffer
And since the brain is active during sleep, so is the predictive coding process. — Christoffer
On what basis do you form that conclusion? In what way does not the science support what I say? Please provide that in order to reject it, your opinion of it is totally irrelevant. — Christoffer
A system of individual parts operating with each other does not mean that if one of the systems fails then all other systems immediately fail as well. — Christoffer
If you distort one of the systems, the experience will alter, but it wouldn't shut off the entire system. — Christoffer
If sense information is disrupted or cut off, the mental model is still trying to predict, but getting no input signals and when comparing, is biased towards the prediction. — Christoffer
I don't think that is the case. The subconscious mind is a part of the brain, that part is a neural net, therefore the subconscious mind is intelligent. I also think that all the memories stored in the subconscious mind are present to it at once otherwise we are dealing with a regress when we try to recall something. — MoK
The rest of the memories are stored in the subconscious mind. — MoK
I said that all memories stored in the subconscious mind are present to it at once. If not, then there must be many subconscious minds each knowing a certain memory at once. There are however two problems here which depend on how the memories are stored in the brain: 1) Either the memories are stored in different subconscious minds independently or 2) The memories are stored in different subconscious minds hierarchically, tree likes.How could it be that all memories which a person has could be present to a mind (subconsciously) at the same time? — Metaphysician Undercover
Not at all. We cannot function very quickly at all otherwise. Please see above.Wouldn't this be amazingly confusing for that subconscious mind? — Metaphysician Undercover
The memories are mainly stored in a part of the brain, what I call the subconscious mind.Do you think that the memories are actually "stored" in the subconscious? — Metaphysician Undercover
The process of recalling is a subconscious activity.Or is it a subconscious activity which brings the memories to the attention of the conscious mind, and the memory itself is not actually stored anywhere? — Metaphysician Undercover
I provided the evidence. Were you not paying attention? — Metaphysician Undercover
I think it's fine in its application to the mental activity of an awake human being. — Metaphysician Undercover
The brain is a prediction machine that continually minimizes free energy—a process that persists even during sleep, when it can update its internal generative models without external sensory input. — Karl Friston
Atienza et al. (2001) reported results where MMN vanished after the subjects fell asleep but
reappeared in phases of REM sleep (Loewy, Campbell, Lugt, Elton, & Kok, 2000; Nittono,
Momose, & Hori, 2001). In this stage, amplitudes were smaller and short-lasting compared to
wakefulness which was hypothesized to result from missing contributions of frontal brain areas
to the responses as well as from unstable, brief representations (Loewy, Campbell, & Bastien,
1996; Nashida et al., 2000). — Lisa Reisinger
Phenomenological aspects of dream experiences were studied in the PC framework (26–28). During sleep, the balance between top-down and bottom-up influences changes; sensory stimuli processing during sleep is attenuated, and attention is directed away from sensory afferents toward internally generated cognitive processes (26, 29), especially during phasic REM sleep (when the most intense forms of dreaming take place) (30). Attenuated precision on lower-level priors shifts the system toward top-down processes, and prediction errors are minimized mainly by higher-order predictions (more abstract, middle- to high-level priors), in contrast to wakefulness when perception is also constrained by sensory afferents (26, 28). Moreover, even if low-level prediction errors occur, they may not reach supramodal frontal and parietal cortices as these regions are relatively quiescent during REM sleep (31–34).Low precision assigned to sensory inputs leads to the dynamic creation of novel predictions to fit rapidly changing neural activations during dreaming (30). Given the lack of external constraints (feedbacks from sensorium), the brain will jump from one prediction to another, leading to bizarre, fragmented, and discontinuous dream narratives with vague, uncertain perceptual qualities (26). — Péter Simor, Tamás Bogdány and Philippe Peigneux
I reject, as pseudo-science, your attempt to apply the theory to dream activity. — Metaphysician Undercover
The evidence is clear and obvious, sensing does not occur in the dream state. Further, sensing is an essential feature of predictive coding. Those two premises are well supported by evidence. Therefore the conclusion, that predictive coding is not applicable to dream activity is well supported by evidence. — Metaphysician Undercover
Notice that the "model is used to predict input signals from the senses that are then compared with the actual input signals from those senses." If you really believe that the theory has been scientifically proven to apply to the dream state, then please explain the science. And don't simply refer to supposed chaotic and erroneous predictions that occur without sense input. — Metaphysician Undercover

Are you familiar with theories of adversarial dreaming? Such theories use the concept of general adversarial networks, they focus on the creative capacity of dreams, and are completely distinct from predictive coding theory:
https://pmc.ncbi.nlm.nih.gov/articles/PMC9071267 — Metaphysician Undercover
In the predictive processing literature, it is generally assumed that *at every layer* feedback forms an effective generative model of that layer. In the hierarchical model here, there is no relation between the intermediate activations in the feedforward path to those in the feedback path. This prevents the integration of top–down information in intermediate sensory areas and makes the model unrealistic.
First, we would like to clarify that the generative pathway in our model generates activities across all layers during both NREM and REM sleep. Second, we agree that our implementation contrasts with the traditional view of the visual cortex where all bottom-up and top-down activities are merged at every layer. From a computational perspective of representation learning, such an architecture can be challenging to train, due to information shortcuts, e.g., V1 → V2 → V1, which would prevent information (at least during reconstruction learning) to propagate to higher areas (e.g., Inferior-Temporal cortex) where compressed representations should be learned. Naturally, this issue would also arise in predictive processing models (unless explicitly or implicitly prevented) as these information shortcuts are a property of the underlying graphical model and not of a particular implementation thereof.
Predictive processing theories propose that these representations emerge from predicting or reconstructing sensory inputs. However, brains are known to generate virtual experiences, such as during imagination and dreaming, that go beyond previously experienced inputs. Here, we suggest that virtual experiences may be just as relevant as actual sensory inputs in shaping cortical representations.

According to your referenced material, the predictive coding process operates with the use of "signals from the senses", which are noticeably absent from the dreaming process. Therefore, predictive coding is absent from the brain process occurring during sleep. — Metaphysician Undercover
Sure, but the way you describe predictive coding all three parts are required for it, as essential aspects. If one part is missing, then the process cannot be called predictive coding. Clearly, "signals from the senses" is an essential aspect of predictive coding, which is missing from the dream activity. Therefore the dream activity cannot be represented as predictive coding. — Metaphysician Undercover
This is not a case of distorting one of the systems, it is a case of one being absent. That's why I very intentionally stressed the point that hallucinating is not the same as dreaming, when you first engaged me. — Metaphysician Undercover
If you are so convinced by "the science", then I assume you can produce the science which shows that the predictive coding model is applicable to brain activity which occurs, with no signals from the senses. I'll be waiting. — Metaphysician Undercover
I said that all memories stored in the subconscious mind are present to it at once. If not, then there must be many subconscious minds each knowing a certain memory at once. There are however two problems here which depend on how the memories are stored in the brain: 1) Either the memories are stored in different subconscious minds independently or 2) The memories are stored in different subconscious minds hierarchically, tree likes. — MoK
It becomes impossible to even show you why you are wrong, where you are wrong and how, — Christoffer
You aren't just calling what I argue about, pseudo-science, you actively point at these studies I've referenced and the science overall, calling it pseudo-science. — Christoffer
And in what way does any evidence of that argue against what I'm saying? — Christoffer
What I argue for is aligned with this; that when sleeping, sensory input is cut off, but the predictive operation continues, forming predictions from long term memory to test against experiences in our short term memory. — Christoffer
The adversarial process is just a layer that grounds this experience through virtual sensations. — Christoffer
And for imagination and creativity when we are awake, it's the same thing, a decoupling of sensory verification using virtual verification to direct predictions from merely operating on reality. — Christoffer
None of this is a rejection of predictive coding, it's just expanding on details. — Christoffer
I'm constantly mentioning how the senses are cut off or scrambled and how it's this very fact that makes predictions unreliable and responsible for the surreal experience. I don't know why you don't get this simple fact and constantly try to change what I say to being that the process is relying on the senses and "have to include it". It's only relying on sense input for us to operating normally when we are awake through grounding the mental predictions. But I've said, numerous times, and it's the damn main point in my argument, that distortion of sense input or a complete lack of it scrambles the prediction ability; generating an experience we can either have as hallucinations or dreams. Just because the grounding data is distorted or gone doesn't mean the brain stops trying to predict in order to reach a state of normal operation. — Christoffer
All three parts are essential for the normal operation when we are awake. — Christoffer
When our sense data is scrambled through drugs, or during sleep... — Christoffer
so it grounds it in something else; the stored experiences in our short term memory as that's where our conscious experience has been stored when awake. — Christoffer
That you say that it can't be called predictive coding if one part isn't working, is just some odd straw-man attempt to render the theory invalid because what exactly? — Christoffer
While when we sleep they're cut off or effectively subdued, and predictions must rely on something else for grounding. — Christoffer
I didn't deny that.What if memory is like I suggested, a pattern of neural activity which is repeated? — Metaphysician Undercover
No, I call the part of the brain where the main part of memories, long-time memories, is held as the subconscious mind.If it is the case, then memories are not things stored in the subconscious, and your post is pretty much irrelevant. — Metaphysician Undercover
The memories are stored in the synapses. Synapses are the junctions between nerve cells. They change when we memorize something new.But if memories are simply neural activity, then they are not "held" anywhere. — Metaphysician Undercover
What do you mean with the mind here? If by the mind you mean a substance, rather than physical, that ideas, such as thoughts, feelings, psychological time, etc. are present to it then I have to say there is a mind with the ability to experience the ideas. The ideas are however the manifestation of the neutrals' activities.They are something which happens, and it happens only when the memory is present to the mind. — Metaphysician Undercover
The memories are stored in the synapses. — MoK

IMO, the boat amazing part of it is that, in my dreams, I am entirely surprised by everything. The scenery. What I find when I walk into a room. Who I run into. What others do. Events like the weather. I, obviously, created everything in my dream. Yet I chose to hide things from myself, and am somehow sble to do so. How do I make a character in my dream do and say everything it does and says, and still be surprised by everything it does and says? — Patterner
It is accurate.I don't think that's accurate. — Metaphysician Undercover
No. The synapses only change when a new thing is memorized or learned.Memory is attributed to synapse regulation, which works through synapse plasticity. — Metaphysician Undercover
No, memory is only a feature of synapses.So memory is a feature of this plasticity, which is a feature of synapse regulation, not the synapse itself. — Metaphysician Undercover
Well, without synapse plasticity we just cannot memorize a new thing.To understand memory is to understand how synapse plasticity is regulated. — Metaphysician Undercover

The synapses only change when a new thing is memorized or learned. — MoK
Well, without synapse plasticity we just cannot memorize a new thing. — MoK
So, the synapses change accordingly to allow for memorizing things in time.Things are being learned and memorized at every moment in time. — Metaphysician Undercover
Do you disagree that memorizing requires synapse plasticity?Memorizing is not a one time thing. Each time a person recollects, and memorizes, one does this in a new situation, under new conditions, therefore a new thing is memorized each time. Notice that to memorize something requires repeating the same thing over and over in the mind. The strength of the memory is dependent on the quality of the repetition. Whenever repetition is done under different conditions it is not really "the same thing" which is repeated. because of the new conditions. Plasticity allows that the memory can be strengthened or altered depending on the conditions of the repetition. — Metaphysician Undercover
So, the synapses change accordingly to allow for memorizing things in time. — MoK
Do you disagree that memorizing requires synapse plasticity? — MoK
Sure, I think that the synapses change all the time. The memory however is stored in a chunk of synapses so it is a collective thing. Any neural net however has a capacity for memorizing things. If you enforce a neural net with limited capacity to learn new things which is beyond its limit then a part of memory is erased as a result.Don't you think so? — Metaphysician Undercover
No, any memory is stored in a chunk of synapsics. Changing one synapse does not necessarily remove the memory but if you insist on changing more synapses then there is a point at which changing one more synapse destroys the memory.I think I was arguing the opposite. What I was saying is that despite talking about memories as if they are fixed objects, stored somewhere, they are never truly fixed. The plasticity means that they are always changing with each recollection. — Metaphysician Undercover
Thank you for your response. I'm understanding it a little more with each reading. But I'm not understanding this:.My way of explaining this is that it is not that you (i.e., that I-ness) which is the agential first-person point of view (i.e., which is the conscious intellect during waking states) that devises the given dream which one as first-person point of view experiences – no more than it is you as an agential first-person point of view which produces that which you see, smell, hear, etc. during waking states. Rather, it is that you (that I-ness) which consists of one’s total self or being (more specifically: one’s total mind, the unconscious aspects of it included) which produces the REM dream which is experienced by you as a first-person point of view during sleep. Just as its your unconscious mind which produces that which you are conscious of during waking states.
But this gets bound up in the philosophy or else psychology of what a self is constituted of. To use William James' basic dichotomy, which mirrors that of Kant’s and of Husserl’s, the first-person point of view is the “pure ego” which is that I-ness that experiences and thereby knows the phenomenal aspects of one’s total self; i.e., the “I” as knower of the experienced self; e.g., I see; I choose, I remember, etc. All aspects of selfhood that are experienced by this same pure ego is then broadly classified as the “empirical ego”; i.e., the “I” as the self which is known via experience (this by the pure ego); e.g. I am tall/short (or: I have two hands); I am stupid/smart in relation to some topic (or: I have an unconscious mind); I am of this or that nationality, etc. The first consciously experiences phenomena; the second is constituted of the phenomena experienced. So, during a dream, the agential first-person point of view (the pure ego) can well be surprised by that which agencies of its total unconscious mind present to it. To further complicate matters, the pure ego can in certain dreams hold an empirical ego quite distinct from its empirical ego during waking states. But this is a very broad and possibly very different topic. — javra
