On Grammar vs. Language in Neurolinguistics Massimo Piattelli-Palmarini (University of Arizona, US) discusses grammar vs. language, the author making the following points: 1) Two styles of explaining the science of mind and behavior have been competing for as long as anyone cares to remember: empiricist, centering on habit formation, statistical learning, imitation and association; and rationalist, focusing on the projection of internally represented rules. Despite relentless effort, the former has delivered rather meager results, whereas the latter, with its pivotal concept of an internally represented grammar, has produced the solid "conceptual cognitive revolution". 2) For a rationalist cognitive scientist, a grammar is a finite mental object, systematically assigning abstract structures to all the well-formed expressions of a language --that is, to each member of a set that, for natural languages (such as Chinese or Italian), is infinite and discrete. Infinite, because every speaker of a language can produce and understand an unlimited number of new grammatical sentences. Discrete, because continuous modification of a sentence to change it into another is impossible. No sentence could be halfway between "It's a good car, but they don't sell it" and "It's a good car, but they don't tell it." 3) A grammar capable of generating complex structures for all well-formed sentences of a natural language must have recursive rules, because phrasal constituents can contain other phrasal constituents of the same or higher kinds ("The young doctor's three beautiful sisters" is a noun phrase containing another noun phrase; "The spy who came in from the cold" is a noun phrase containing a sentence). Moreover, structural rules of sentence formation can be applied recursively to embed relative clauses embedding other relative clauses, without limit (as in "This is the cat that killed the rat that ate the malt that lay in the house that Jack built"). Because such grammars are finite, whereas the languages they generate are infinite and contingently shaped by use, it is advantageous, and methodologically cogent, to consider the concept of grammar as primary, and that of language as derived. 4) Since the mid-1950s, powerful formal criteria, derived from analysis of the artificial languages of mathematics and computer programming, have been applied to the study of natural languages to determine principles by which a given class of grammars can generate a given target language. A universal ('Chomsky') hierarchy of grammars (automata) was established: the most powerful class contains as a subclass the immediately less powerful one, and so on. In tune with the dominant empiricist-inductivist tradition of the 1950s, the first grammars to be explored at the lowest level in the hierarchy were probabilistic and finite-state. From a very large corpus of ascertained utterances of the language, one can compute the conditional probability that a word (or string of words) will follow another. References: 1.

In the popular view, a language is merely a fixed stock of words. Purists worry about foreign loanwords; conservatives decry slang; and groundless claims that there are hundreds of Eskimo words for snow are constantly made in popular writing, as if nothing matters about languages but their lexicons. But the popular view cannot be right, because (as linguist Paul Postal has observed) membership in the word stock of a natural language is open. Consider this example: "GM's new Zabundra makes even the massive Ford Expedition look economical." If English had an antecedently given set of words, then this expression would not be an English sentence at all, because 'Zabundra' is not a word (we just invented it). Yet the sentence is not just grammatical English, it is readily interpretable (it clearly implies that the Zabundra is a large, fuel-hungry sports utility vehicle produced by General Motors). Similar points could be made regarding word borrowing, personal names, scientific nomenclature, onomatopoeisis, acronyms, loaned words, and so on; English is not a fixed set of words. A more fundamental reason that a language cannot just be a word stock is that expressions have syntactic structure. For example, in most languages, the order of words can be significant: "Mohammed will come to the mountain" contains the same words as "The mountain will come to Mohammed", but the expressions are very different.

Saffran et al (University of Wisconsin Madison, US) discuss the acquisition of language by children, the authors making the following points: 1) Before infants can begin to map words onto objects in the world, they must determine which sound sequences are words. To do so, infants must uncover at least some of the units that belong to their native language from a largely continuous stream of sounds in which words are seldom surrounded by pauses. Despite the difficulty of this reverse-engineering problem, infants successfully segment words from fluent speech from approximately 7 months of age. 2) How do infants learn the units of their native language so rapidly? One fruitful approach to answering this question has been to present infants with miniature artificial languages that embody specific aspects of natural language structure. Once an infant has been familiarized with a sample of this language, a new sample, or a sample from a different language, is presented to the infant. Subtle measures of surprise (e.g., duration of looking toward the new sounds) are then used to assess whether the infant perceives the new sample as more of the same or something different. In this fashion, we can ask what the infant extracted from the artificial language, which can lead to insights regarding the learning mechanisms underlying the earliest stages of language acquisition. 3) Syllables that are part of the same word tend to follow one another predictably, whereas syllables that span word boundaries do not. In a series of experiments, it has been found that infants can detect and use the statistical properties of syllable co-occurrence to segment novel words. More specifically, infants do not detect merely how frequently syllable pairs occur, but rather the probabilities with which one syllable predicts another. Thus, infants may find word boundaries by detecting syllable pairs with low transitional probabilities. What makes this finding astonishing is that infants as young as 8 months begin to perform these computations with as little as 2 minutes of exposure. By soaking up the statistical regularities of seemingly meaningless acoustic events, infants are able to rapidly structure linguistic input into relevant and ultimately meaningful units. Proc. Nat.

"Random" is not equal to "uniforrmly random", >thus one can find broadbrush patterns in random phenomena. > > Looking at the Eonix page where I read: At a time when theories of evolution are undergoing renewed controversy, discussion is hampered by the remoteness of the phenomenon of evolution, and the use of indirect inference to speculate about natural selection in processes that have never been observed. Adherents of Darwinism often defend textbook versions of the theory that have, in any case, often been held in question. The assumption that evolution occurs, and must occur, by random mutation and (non-random) natural selection is the crux of the dispute, and one unreasonably confused with issues of religion and secularization. The demonstration of non-random evolution in the eonic effect must severely caution Darwin's incomplete theory. I realize I have to expand what I wrote. It is best explained via equations. Let f(t) be some function of time, and r(t) be a random function of time. Then if y(t)= r(t)*f(t) and x(t)=r(t)+f(t), both x(t), and y(t) are random processes. This is due simply to definition of randomness. To apply directly to evolution, let the "evolution" of something very simple be given by the equation dz(t)/dt + a(t)*z(t) = f(t) This is the simplest, first-order, linear, ordinary differential equation and has a solution in the most general case i.e. a(t) is a function of time (not constant). Here, a(t) is a coefficient of the DE, and f(t) is known as the "forcing function" or "source term". The reason for it is physical. The DE can be solved without f(t) and that is known as the homogeneous solution. It is an exponentially decaying solution, that is, it goes to zero as time goes to infinity. However, if f(t), say, is sin(t), then this sinusoidal function "drives" the system (e.g. the value of z(t)) in the sense that it does not go to zero. That is why f(t) is also known as "forcing". It forces the system to behave in a way that it would not behave if left alone. In other words, without f(t) the equation describes the behavior of the system itself, and f(t) is then considered external to the system but which obviously affects the behavior of the system. Rewrite it as L(t)z(t)=f(t) where L(t) is a (linear) operator. Obviously, L(t) is nothing more that d/dt + a(t). This "operates" on the system (i.e. z(t)). To generalize, suppose z(t) is now a vector. It is a set of variables. This particular way of looking at a system is that z(t) is a set of variables that describes the system, and at any time the specific values of these variables is the "state" of the system. So, we can think of evolutionary states in similar ways. For example, it could be 30,000 dimensions for humans. That is the state of each gene. Or better yet, let the state of the system be 30,000*N where N is the number of humans in the world. Then the "state" is the set of all genes of all humans. So then if a(t) (which is also a vector) is random, then the operator L(t) now generates random mutations in the gene pool of humanity. And here is the crux of the matter: the f(t) now determines which direction evolution moves by forcing the system state to some direction. So mathematically we now have a description. Caveats: 1. It is linear and simple. Real evolution is likely not. But the mathematical description can be extended to nonlinearity easily. 2. Both mutation (a(t)) and environment (f(t)) are now part of the description. 3. Because the solution is a function of both f(t), and a(t) it is still random. 4. We see that f(t) models environment, however, nobody can predict the environment. As Bohr quipped "prediction is difficult, especially the future". So unfortunately, f(t) must also be thought of as a random variable. The effects of f(t) at any time is direct, but knowing what it is or will be, mathematically it must be modeled as a random variable. The difference is this: a(t) acts on a fast scale, but f(t) acts on a slower scale. ---<><><><><><><><><><><><>----Language----<><><><><><><><><><><><><> Copyrights/"Fair Use": http://www.templetons.com/brad/copymyths.html The "fair use" exemption to copyright law was created to allow things such as commentary, parody, news reporting, research and education about copyrighted works without the permission of the author.

And soon I will be working on "population genetics" models with a colleague whose specialty is dynamics (in fact, population dynamics) and we will be working on language evolution. To add more, the partial differential equations for the pdf (prob density function) of random processes are the so-called diffusion models, and I have already done work in this field and understand it reasonably well. You can also read about them in both of these books: Hubey, H.M. 1999, Mathematical Foundations of Linguistics, Lincom Europa Hubey, H.M. 1994 Mathematical and Computational Linguistics, Mir Domu Tvoemu, Moscow (this later published by Lincom Europa in 1999). Longer and more detailed versions of these books (with examples and exercises suitable for teaching) will be eventually published. >Consider finally a puzzle.

It is exactly because it is so difficult to explain that so much precision and detail are needed. There are tons of mathematical materials on probability theory, stochastic processes, plausible reasoning (See Jaynes' book), etc. It is a very rich field and also very powerful. Today most of datamining, model-building, search for patterns, knowledge discovery are all tied together within the view point of probability theory, namely Bayesian reasoning. See the book by Hastie, Tibshirani, and Feldman for the last 30 years of research in this field. >------------------------ > >Date: Tue, 22 Oct 2002 08:02:18 EDT >From: Nemonemini at aol.com >Subject: Re: 13.2721, Disc: Darwinism & Evolution of Lang > >Re: Linguist 13.2721 > > > >>It is best explained via equations.

More specifically, infants do not detect merely how frequently syllable pairs occur, but rather the probabilities with which one syllable predicts another. Thus, infants may find word boundaries by detecting syllable pairs with low transitional probabilities. What makes this finding astonishing is that infants as young as 8 months begin to perform these computations with as little as 2 minutes of exposure. By soaking up the statistical regularities of seemingly meaningless acoustic events, infants are able to rapidly structure linguistic input into relevant and ultimately meaningful units. Proc. Nat.

Adherents of Darwinism often defend textbook versions of the theory that have, in any case, often been held in question. The assumption that evolution occurs, and must occur, by random mutation and (non-random) natural selection is the crux of the dispute, and one unreasonably confused with issues of religion and secularization. The demonstration of non-random evolution in the eonic effect must severely caution Darwin's incomplete theory. I realize I have to expand what I wrote. It is best explained via equations. Let f(t) be some function of time, and r(t) be a random function of time. Then if y(t)= r(t)*f(t) and x(t)=r(t)+f(t), both x(t), and y(t) are random processes. This is due simply to definition of randomness. To apply directly to evolution, let the "evolution" of something very simple be given by the equation dz(t)/dt + a(t)*z(t) = f(t) This is the simplest, first-order, linear, ordinary differential equation and has a solution in the most general case i.e. a(t) is a function of time (not constant). Here, a(t) is a coefficient of the DE, and f(t) is known as the "forcing function" or "source term". The reason for it is physical. The DE can be solved without f(t) and that is known as the homogeneous solution. It is an exponentially decaying solution, that is, it goes to zero as time goes to infinity. However, if f(t), say, is sin(t), then this sinusoidal function "drives" the system (e.g. the value of z(t)) in the sense that it does not go to zero. That is why f(t) is also known as "forcing". It forces the system to behave in a way that it would not behave if left alone. In other words, without f(t) the equation describes the behavior of the system itself, and f(t) is then considered external to the system but which obviously affects the behavior of the system. Rewrite it as L(t)z(t)=f(t) where L(t) is a (linear) operator. Obviously, L(t) is nothing more that d/dt + a(t). This "operates" on the system (i.e. z(t)). To generalize, suppose z(t) is now a vector. It is a set of variables. This particular way of looking at a system is that z(t) is a set of variables that describes the system, and at any time the specific values of these variables is the "state" of the system. So, we can think of evolutionary states in similar ways. For example, it could be 30,000 dimensions for humans. That is the state of each gene. Or better yet, let the state of the system be 30,000*N where N is the number of humans in the world. Then the "state" is the set of all genes of all humans. So then if a(t) (which is also a vector) is random, then the operator L(t) now generates random mutations in the gene pool of humanity. And here is the crux of the matter: the f(t) now determines which direction evolution moves by forcing the system state to some direction. So mathematically we now have a description. Caveats: 1. It is linear and simple. Real evolution is likely not. But the mathematical description can be extended to nonlinearity easily. 2. Both mutation (a(t)) and environment (f(t)) are now part of the description. 3. Because the solution is a function of both f(t), and a(t) it is still random. 4. We see that f(t) models environment, however, nobody can predict the environment. As Bohr quipped "prediction is difficult, especially the future". So unfortunately, f(t) must also be thought of as a random variable. The effects of f(t) at any time is direct, but knowing what it is or will be, mathematically it must be modeled as a random variable. The difference is this: a(t) acts on a fast scale, but f(t) acts on a slower scale. ---<><><><><><><><><><><><>----Language----<><><><><><><><><><><><><> Copyrights/"Fair Use": http://www.templetons.com/brad/copymyths.html The "fair use" exemption to copyright law was created to allow things such as commentary, parody, news reporting, research and education about copyrighted works without the permission of the author.

And soon I will be working on "population genetics" models with a colleague whose specialty is dynamics (in fact, population dynamics) and we will be working on language evolution. To add more, the partial differential equations for the pdf (prob density function) of random processes are the so-called diffusion models, and I have already done work in this field and understand it reasonably well. You can also read about them in both of these books: Hubey, H.M. 1999, Mathematical Foundations of Linguistics, Lincom Europa Hubey, H.M. 1994 Mathematical and Computational Linguistics, Mir Domu Tvoemu, Moscow (this later published by Lincom Europa in 1999). Longer and more detailed versions of these books (with examples and exercises suitable for teaching) will be eventually published. >Consider finally a puzzle.

It is exactly because it is so difficult to explain that so much precision and detail are needed. There are tons of mathematical materials on probability theory, stochastic processes, plausible reasoning (See Jaynes' book), etc. It is a very rich field and also very powerful. Today most of datamining, model-building, search for patterns, knowledge discovery are all tied together within the view point of probability theory, namely Bayesian reasoning. See the book by Hastie, Tibshirani, and Feldman for the last 30 years of research in this field. >------------------------ > >Date: Tue, 22 Oct 2002 08:02:18 EDT >From: Nemonemini at aol.com >Subject: Re: 13.2721, Disc: Darwinism & Evolution of Lang > >Re: Linguist 13.2721 > > > >>It is best explained via equations.
