There are things we cannot explain like how there are smaller groups who are gepgraphically remote from each other and yet share common features in the in languages. There is the theory that some of out langiage ability is somehow hard wired.

(Sorry about the time it...Thanks for your comment. (Sorry about the time it took to show up, my available time and access to on-line activity are spotty.)<br /><br />First I should mention that I strongly suspect that there are many different modes of representing "concepts" in the brain, some of which are probably very stable, changing typically over a time-frame of years (in humans). Others probably change more quickly.<br /><br />The basic (slowly changing) concept representations probably are used in more abstract thinking, while the more fluid one(s) lie closer to the instantiation and interpretation end of the spectrum.<br /><br />For me, the best representation of a "primitive concept" is that of picking up something off the ground in (<i>e.g.</i> Rhesus) monkeys. It's known that there are several functions within the monkey's brain that act very similarly both when the monkey takes such an action, and when it sees another monkey take the action.<br /><br />Picking something up off the ground would be a fairly abstract concept, with more concrete representations involving specific items, specific locations, and specific social consequences, the latter being partly determined by which other monkeys are present to see the action. (Note that monkeys in general don't seem to have an awareness of other monkeys' points of view (how much they can see of the action), but great apes have been (probably) shown to have such abilities.)<br /><br />Another good example would be grasping a branch during brachiating travel. This would be closer to your discussion of variability, but again at some level the "concept" would have to be very stable, so as to encode valuable knowledge about how branches in general behave when grasped by a moving animal. This fits well with the high level of connectivity between the pre-frontal lobe and the cerebellum.<br /><br />In general, I suspect the fluidity you mention is more a matter of neural firing patterns, while the stability I'm talking about is in the behavior that produces any immediate firing pattern.<br /><br />As for bio, I prefer what I say to stand on its own merits.AKhttps://www.blogger.com/profile/10905636789614137068noreply@blogger.comtag:blogger.com,1999:blog-7994102333633449677.post-82557768187379619952010-07-13T10:51:01.962-05:002010-07-13T10:51:01.962-05:00Hi,

Tuesday, July 14,...Hi,<br /><br />I v. much like your post :<br /><br />Tuesday, July 14, 2009<br />Concepts, Cognition, and Anthropomorphism <br /><br />wh. deals with some extremely important stuff. I too think - if i understand you - that concepts are represented in some kind of outline/ideogram mode in the brain.<br /><br />However, as I understand you, you seem to think that these outlines are relatively fixed:<br /><br />"it's a good guess that those neurons occupy a specific location in some n-dimensional "concept space" that corresponds to the specific act involved."<br /><br />I however believe that those concept outlines in the brain must be extremely rough and **fluid**. Bear in mind for a start that the concepts often are derived from moving objects.<br /><br />They are there IMO to be fleshed in - in extremely flexible fashion, according to the situation - and particular application of the concept.<br /><br />I am v. grateful to you for linking concepts to direct physical action, as you do. This is clearly an essential way of approaching concepts - as opposed to beginning with v. airy abstract concepts, (such as "ideas","politics").<br /><br />And physical actions demonstrate the need for extremely fluid concept outlines. We think both proactively and reactively, for example in terms of "hold the cup", "eat/ chew your food", "catch the book", "step on the ball" etc etc.<br /><br />The concept outline for "hold" must be capable of being instantiated in a virtually infinite diversity of hand forms according to the object held. Ditto physical actions like "eating"/"chewing"/ "catching" will have to take vastly diverse physical, muscular forms according to their relevant objects. Stepping on a ball will be radically different to stepping on an ordinary stone step. <br /><br />P.S. Who are you? I can't find any bio details.mike t.noreply@blogger.com
