No one hits a ping-pong ball by seeing where it is or even by believing he sees it where it is. The delays in the physical motion of our muscles are just as long as the synaptic delay--on the order of magnitude of .1 second. He aims his paddle so that when it completes its planned motion it will be at the point where he also expects the ball to be. And both the planning of the motion of the arm he controls and the expectation of the motion of the paddle governed only by inertia, gravity and air pressure is derived from kinematic calculations. I suppose you could call that real-time simulation since it's a mental hologram, as it were, of the projected path of both the ball and the paddle. But I don't think it fits your definition of RTS because its performed to compensate for the delay in the motion of the arm, not the synaptic delay. Even though the timing and the result are roughly the same, the process is not. Also, it doesn't fit your definition of RTS because no advanced evolution was involved.
I have never defined the RTS, but I agree with most of this, except the "he aims his paddle" seems to ignore or greatly over simplify what is actually happening. In my POV a conscious "he" is only an observer/ perceiver of the action. A conscious "he" had nothing to do with planning how to hit the ball.
About 30 (or more?) years ago, Dr. Libbet demonstrated that our decision only appear to be made by "us." Actually they are made and then we learn of them and falsely think "we" made them. Libbet's technique was simple and clever: He had surface electrodes on the exposed brain of his alert patients, mainly in the pre-motor cortex as I recall. The patient would push a button at random interval, whenever “he” decided to do so. He also watched a clock, which had a much faster than normal sweep second hand, and reported the position of that sweeping second hand when he had decided to push the button, but the report was after the button was pushed (avoiding some possible confusing motor/motor interactions).
Libbet’s electrical records recorded the neural activity associated with the planning of the mussel commands needed for the button push up to a second prior to the reported decision making instant. Within the last few years, using MRI techniques, focused on activity in the frontal lobes, it has been shown that decision related activity may begin even 10 seconds prior to the subject deciding to push a button.
Even something as simple as pushing a button, which your finger is already resting on, is very complex, tightly scheduled, set of planned mussel commands, Some mussels must be relaxed while their counter posed mussels are contracted, all in an analog fashion for smooth motion. Walking is an extremely complex rhythmic cycle that does include corrections for even the transmission delays of neural impulses traveling down the long axons to the feet. It typically takes a year to learn how to walk – how complex that simple act is only became very clear when man tried to make a robot do it (even very poorly).
My point is that “I” have nothing to do with the complexities of a fast game of ping-pong. “I” only think “I” do.
I will try to define a little what I think is the RTS. It certainly includes both the correction for the synaptic delays of the sensor system AND all of the delay and complex sequential scheduling of the mussel commands for even the simplest actions, like reaching for a glass of water, which is an integrated eye/ hand feedback process. Thus, both the sensory sensations and my body’s movement activities are experienced by “me” in real time, but “I” am oblivious to the complexity actually taking place earlier. “I” only perceive the act and think “I” made it happen, but really my brain did and “I” only watched, like a passive observer. Libbet’s and the recent MRI experiments show this is the case.
“I” am only a very tiny component in the RTS. That “I” component is mainly supplied to the parietal RTS by and from the frontal cortex. – Much like the old Fortran “subroutine call routines” (I assume you remember Fortran.) “I” am very actively evolving in the frontal cortex, connected to my memories, emotion states, and beliefs, much like an active data set with constant processing by many different users occurring; however, “I” am oblivious to all this activity, which is actually changing “me.” “I” can ONLY perceive my current nature, the location of my limbs and their movements, in the real time model of my body and the external world, etc within the parietal RTS. “My” perceptions / experiences in this simulated world are “returned” to the frontal lobe, again much like the information returned to the subroutine of an old Fortran call.
I.e. although I am constantly evolving via frontal lobe activity (perhaps becoming happy or sad) “I” do not experience / perceive this frontal lobe activity. “I” find out or perceive the changes in “me” within the RTS, just as it is only there that “I” learn about the decisions made earlier by my brain but I believe “I” am playing a good game of ping-pong making the decision to try to put spin on the ball etc. but in reality, “I” am only a self deluded passive observer of what my body (brain included) have earlier done.
Other species, felids in particular but also many or most of the advanced primates, are very adept at kinematic calculation.
Homo sapiens likely prevailed because the ice age the Neanderthals were better adapted for was ending. Anomalies in the DNA of Europeans suggest that they assimilated the surviving small population of Neanderthals by interbreeding. You might consider adopting Jungian terminology for clarity--not to mention ease of punctuation.
His terms include the "conscious," "unconscious" and "dream ego."
I have read only a little of Jung. Not sure I accept his “collective conscious” POV but I do think humans come with some archetypes. Even most primates do. For example, a monkey born and raised for years in captivity will instinctively flee from the first snake it sees but most other animals are attractions for it – things to play with or torment. As Freud is so much better known and also uses many of the same terms, I try not to use any of them (except “conscious” in the sense of “aware of”) . I do not want the prior concepts, but try to define my ideas without them.
As you like birds, you probably know that the Baltimore Orel makes a distinct hanging nest. I think it was Florida where none are found that there was a large aviary with many other bird types. Some Baltimore Orel eggs were hatched there in it. When they were mature, they built their characteristic nest although they were not raised in one and never saw one. All animals, humans included, have strong built-in behavior dispositions and concepts (archetypes, if you like). The existence of some greater power (God) is probably one, but it may just be the sequence of transfers from the initially omnipotent mother to a postulated God when she is discovered to be lacking, as Freud suggested. I liked
The Economist discussion of why these, even the psychological attitude, archetypes evolved. See it at:
http://www.economist.com/science/displaystory.cfm?story_id=12795581
IMHO, it is one of the best articles they have publised in last several issues. I think you will like reading it if you have not.
With the above discussion of the separate frontal lobe unconscious processing of “me” perhaps I can make clear what I think is the difference between human and many animals’ RTSs, including birds. I am nearly certain that birds have a RTS also as flying thru a ticket with many tiny branches at high speed does not seem to be possible without a real time understanding or where its wings are wrt the multitude of branches and twigs. I suspect, however, that the bird does not have any “I.” I.e. I think birds are very sophisticated biological machines. Some of the higher primates, and probably the Neanderthals, have/ had an “I,” but not as complex as that of the early humans. I.e. were not as “constructively conscious” but perhaps mainly “passively conscious.”
I think it was Humphrey who first advance a plausible reason why humans have an “I”/ are “constructively conscious,”* not just “passively conscious.” – We could just be biological robots too. (Concept referred to in this context as “zombies” but totally distinct for the “living dead” of Haiti etc.) As Humphrey put it: The function of consciousness, (or the existence of an “I,” I add) is to let our hypotheses die instead of us. – I.e. “We” can and do consider ourselves and the probably consequence of various alternative acts before doing one.)
I doubt dogs have any significant “I” because of an experiment done long ago (Pre-Human Society days.):
There were about 20 “pound dogs” which had been held the require time, unclaimed. They were tied by short leash to stakes spaced uniformly around a small circle and had not been feed that day yet. The pound keeper, who normally feed them, was in the center of the circle with a club. Systematically he approached one dog and clubbed it to death and then returned to the center of the circle before doing the same to the next dog. As he approached the next dog (and even the very last one still alive later) it exhibited “happiness signs” (tail wagging, advancing towards its approaching killer as far as the short leash would allow.) Not one dog seemed to understand that it was about to be clubbed to death but behaved as if it expected to finally be feed that day’s meal, by the man who normally did so.
-----------------
*As explained earlier, much of human “constructive consciousness” is unconscious activity in the frontal lobes that “we” become conscious of later when the results are available in the RTS. This is NOT to say that no “thinking” occurs within the RTS. – Yes we can consciously, especially via the use of language, consider various alternative acts.
Feral children (without language) however, I suspect do not think consciously but they surely do “think” in the sense of evaluate various alternatives and transfer one to the RTS to use and become aware of. – This is just speculation, of course. Based on what I read years ago about a feral child a German doctor tried to teach language to, tried to “civilize” etc.
