In the present study, using event-related functional magnetic resonance imaging, we investigated a group of participants on a grammaticality classification task after they had been exposed to well-formed consonant strings generated from an artificial regular grammar. We used an implicit acquisition paradigm in which the participants were exposed to positive examples. The objective of this studywas to investigate whether brain regions related to language processing overlap with the brain regions activated by the grammaticality classification task used in the present study. (...) Recent meta-analyses of functional neuroimaging studies indicate that syntactic processing is related to the left inferior frontal gyrus (Brodmann's areas 44 and 45) or Broca's region. In the present study, we observed that artificial grammaticality violations activated Broca's region in all participants. This observation lends some support to the suggestions that artificial grammar learning represents a model for investigating aspects of language learning in infants [TICS 4 (2000) 178] and adults [Proceedings of the National Academy of Sciences of United States of America 99 (2002) 529].

C HL is Noam Chomsky's shorthand for "Single Computational System of human language." C HL is that part of the faculty of language (FL) that integrates lexical information to form linguistic expressions at the interfaces where language interacts with other cognitive systems. In this paper, I am asking whether the elements of FL are dedicated to language alone, or whether significant parts of FL might apply beyond language. From a close examination of the properties of the principles of C HL (...) , I argue that they might well apply to a class of natural symbol systems that includes language and other cognitive systems. This issue of linguistic specificity differs from a similar issue raised recently by Chomsky. For Chomsky, while the "elements" of the linguistic system per se are drawn from all over nature, general principles of computational efficiency control the operation of the system. Currently, there is little empirical motivation for this vast generalization to all of nature. The more restricted generalization proposed here looks better suited to the current form of inquiry on language and related system. (shrink)

A cultural change occurred roughly 40,000 years ago. For the first time, there was evidence of belief in unseen agents and an afterlife. Before this time, humans did not show widespread evidence of being able to think about objects, persons, and other agents that they had not been in close contact with. I argue that one can explain this transition by appealing to a population increase resulting in greater exoteric (inter-group) communication. The increase in exoteric communication triggered the actualization of (...) a dormant potential for greater syntactic computational power; specifically it triggered syntactic movement. Syntactic movement, in turn, made possible variable binding, which crucially figures into cognition by description, a naturalistic analogue of Russell’s knowledge by description. Cognition by description made possible the ability to conceive of things one had never experienced, such as mythological beings, places only visited by the dead, and so forth. The Amazonian Pirahã provide some corroboration for this hypothesis, since they exhibit the combination of traits here attributed to Middle Paleolithic individuals, namely exclusively esoteric (intra-group) communication, evident lack of syntactic movement, and a limitation to knowledge (cognition) by acquaintance.
