Terrific talk. Current theories of consciousness focus on 'sentience' and "qualia' and ignore function. Wild, untamed philosophy. This approach makes much more sense.
Thank you for this presentation. I'm in a different field but have been making this argument for about ten years. So credible explanation from within the field will help other fields that require this explanation in order to disabuse others of their ... shall we say, philosophical or pseudoscientific priors.
Consciousness as part of a process of encoding experience would be the more precise way of expressing this notion. "consciousness as a memory system" seems to imply that memory is the end result or objective, but encoded experiences act as templates for future actions or as comparisons to current experience. The process is for extracting/adjusting our causal understanding to use as templates in future instances. In the process of extracting/adjusting/encoding the bound synchronous activation through the ensembles is experienced as consciousness. We know that recalling a memory is actually rewriting the template. This is an effortful process!
This talk is enlightening; sheds so much light into consciousness and our internal unconscious processes and how the mind and mindfulness practices can train our unconscious; light on subconscious and unconscious communication that can be happening outside our awareness, but that we can however train... Super empowering...
ridiculously underrated. amazingly free.

Mind blowing
I would love to further discuss your findings with regard to trauma and childhood adaptivity to adversity. I believe this could be linked with Vagal theory to help explain a child's innate resilience, also what could also be a great contributor to dissociation, psychosis and/or schizoaffective disorders.
This seems to agree with all of the examples used in Robert Sapolsky's argument against free will.
Dementia’s positives are, at least at the beginning of the illness, under rated! You only need one book and one movie and one beautiful spot to visit! Every time it is a new experience! Not to mention the selective amnesia about people who you should not have known in the first place. Eviction time!
I get your point. My sister is very forgetful. She doesn’t have dementia but she forgets when i tell her jokes or stories. I keep telling her the same stuff and she enjoys it every time
Maybe she doesn't want to hurt your feelings, and thinks you're stupid because you keep telling the same stories over and over again.:-)
@@andrewowens5653 nope. I ask her about the plot and she doesn’t remember
Interested to see how the variance between neurotypical and autistic saccadic suppression would impact these sensorimotor delays. The overactive amygdala may excessively interpret incoming data due to differing frame rates.
This lecture is tainted by the false idea of the primacy of consciousness, i.e., that the mind creates parts or the whole of its objects. The logical gap in argumentation is very clear: direct perception is delayed perception; delay does not mean that the mind fabricates percepts, as the implication of the talk goes. Obviously, nothing happens in an instant, and recent perception does condition later perception in all sorts of ways. But this does not mean that perception is indirect. It is direct *and* delayed, and that's not a contradiction. The process that forms perceptions does not temper with the content - the 'what am I perceiving' - it just grasps it *through* a short duration of activity of sense organs and the nerve system. The issue of models, ideas, and expectations is truly bizarre and taken straight out of Kant. How on earth can you move from perception taking time to perception depends on prior concepts? That's a gigantic illogical leap. Our conceptual knowledge is activated very quickly when we perceive and is applied to the percepts, but it does not change the perceptions. Think, for example, of a doctor: he sees certain symptoms, and his mind immediately concludes that this man has scurvy. I see the same person in approximately the same manner, but I don't conclude that about him because I am ignorant of medicine. You see? Same perceptions, different conceptual awareness. We both *perceive* the same thing, but we have different concepts. So, concepts can not participate in the mechanics of perception. The latter is physiological. I think this comes from a basic equivocation found all over this talk: you equivocate memory with delayed effects on consciousness. That can't be right. A stimulus can be registered in the body and only form finished awareness after a short while, but that can be something like the hysteresis of the system. For example: at the turn of the switch, the car is not yet running. But this does not mean that the car has memory in a literal sense in the state of being able to be driven of the switch being turned. It's just that the turning of the switch came to fruition only sometime after in the state of the car. Memory is more than this kind of delayed response and registration. It is more complex and psychological. This is why you took a Kantiam turn in your talk: you equate falsely memories that do involve concepts (in humans) with this kind of time-taking perception of motion and change etc.
That is the question. Relationship.
Thank you for this. Felt like something wasn't correct. The question about the trolley problem really exposed it. This explanation you have written seems to explain the discrepancy between the they presented and personal experience/contemplation/logic. Will endeavour to interpret.
Whole "view" of my (and all) mind(s) destroyed and can't make a new view. Now completely LOST, thanks doc!
Understanding existence eludes me
None of the actions described at 22:14 can be done if one is not physically conscious and able to move. For a person who is unconscious only vital organs like heart, lungs keep working for some time which can be pretty long. But that person, even if dehydrating, cannot do all the necessary chores to quench his his/her thirst. Doing of those actions might look automatic because one has done that many many times. I teach Physics. I can write board after board deriving equations from first principles and drawing graphs etc. without looking at a piece of paper. I can only do that as second nature because I have been doing such for forty years. I cannot even write F = ma if and when I faint. It has happened to me several times. F = ma was not erased from my memory. I just could not access my memory when physically unconscious
The term "unconscious" is not being used in the way you are referring. Rather it is confusingly meant to describe brain processes that one is unaware of and that are quick and intuitive.
A lot of this is obvious to musicians. When you play music on say the piano there’s no way you can be consciously aware of the keys you are hitting. Matter of fact if you think about the next note then you are likely to get lost since you are not playing with your conscious mind, something else, maybe your soul.
Not as obvious as one would image. As Daniel Kahneman described them, System 2 is required to learn how to play piano and requires much practice before it becomes a System 1 type or intuitive of process. These lecture does not touch on these aspects of S1 & S2.
Amnesia patients aren't "conscious?"
The real problem of consciousness is how one defines it. Does consciousness mean an awake state of being where one is experiencing (as opposed to being sedated or in a coma)? In this case, an amnesia patient would be described as "conscious" if they are alert and can answer questions, even if their memories are unavailable.
10:37 dos tipos de qualia: sensibles y volitivos .. y entre medias, la memoria?
Here is what Budson does not explain:
Interaction with the Subconscious
Both System 1 and System 2 interact with the subconscious, albeit in different ways. System 1 heavily relies on the subconscious, drawing from stored memories, experiences, and learned patterns to make quick, intuitive decisions without conscious effort. This subconscious processing allows for rapid responses to familiar situations and the ability to recognize patterns and emotions almost instantaneously. On the other hand, while System 2 is primarily engaged in conscious, deliberate thought, it also taps into the subconscious for information and insights that support its analytical processes. For instance, when solving a complex problem, System 2 might subconsciously retrieve relevant information and past experiences to inform its reasoning. Thus, the subconscious plays a crucial role in both systems, underpinning the fast, automatic responses of System 1 and the more deliberate, reflective processes of System 2.
38:15 crazy.... your conscious mind thinks of its itself as the conscious part but you mostly do the unconscious stuff
Agree with all of the set-up, but by 14 min he is talking about the theory of why, and it's wrong. Self-awareness is a side effect of our ability to communicate abstract ideas. Consciousness is not some grand thing, just a grand term that invites grand explenations (that fail).
Square peg in round hole... there is no "backwards in time." Thats just a strange conclusion based on a flawed assumption.
