Arbib/From monkey-like action recognition to human language: BBS Call for Commentators

by Behavioral & Brain Sciences

Below please find the abstract, keywords, and a link to the full text of the forthcoming BBS target article: From monkey-like action recognition to human language: An evolutionary framework for neurolinguistics Michael A. Arbib This article has been accepted for publication in Behavioral and Brain Sciences (BBS), an international, interdisciplinary journal providing Open Peer Commentary on important and controversial current research in the biobehavioral and cognitive sciences. Commentators must be BBS Associates or suggested by a BBS Associate. To be considered as a commentator for this article, to suggest other appropriate commentators, or for information about how to become a BBS Associate, please reply by EMAIL within three (3) weeks to: calls(a)bbsonline.org The Calls are sent to 10,000 BBS Associates, so there is no expectation (indeed, it would be calamitous) that each recipient should comment on every occasion! Hence there is no need to reply except if you wish to comment, or to suggest someone to comment. If you are not a BBS Associate, please approach a current BBS Associate (there are currently over 10,000 worldwide) who is familiar with your work to nominate you. All past BBS authors, referees and commentators are eligible to become BBS Associates. An electronic list of current BBS Associates is available at this location to help you select a name: http://www.bbsonline.org/Instructions/assoclist.html If no current BBS Associate knows your work, please send us your Curriculum Vitae and BBS will circulate it to appropriate Associates to ask whether they would be prepared to nominate you.

Arbib ABSTRACT: The article analyzes the neural and functional grounding of language skills as well as their emergence in hominid evolution, hypothesizing stages leading from abilities known to exist in monkeys and apes and presumed to exist in our hominid ancestors right through to modern spoken and signed languages. The starting point is the observation that both premotor area F5 in monkeys and Broca's area in humans contain a "mirror system" active for both execution and observation of manual actions, and that F5 and Brocas area are homologous brain regions. This grounded the Mirror System Hypothesis of Rizzolatti & Arbib (1998) which offers the mirror system for grasping as a key neural "missing link" between the abilities of our non-human ancestors of 20 million years ago and modern human language, with manual gestures rather than a system for vocal communication providing the initial seed for this evolutionary process. The present article, however, goes "beyond the mirror" to offer hypotheses on evolutionary changes within and outside the mirror systems which may have occurred to equip Homo sapiens with a language-ready brain. Crucial to the early stages of this progression is the mirror system for grasping and its extension to permit imitation. Imitation is seen as evolving via a so-called "simple" system such as that found in chimpanzees (which allows imitation of complex "objectoriented" sequences but only as the result of extensive practice) to a so-called "complex" system found in humans (which allows rapid imitation even of complex sequences, under appropriate conditions) which supports pantomime. This is hypothesized to provide the substrate for the development of protosign, a combinatorially open repertoire of manual gestures, which then provides the scaffolding for the emergence of protospeech (which thus owes little to non-human vocalizations), with protosign and protospeech then developing in an expanding spiral. It is argued that these stages involve biological evolution of both brain and body. By contrast, it is argued that the progression from protosign and protospeech to languages with full-blown syntax and compositional semantics was a historical phenomenon in the development of Homo sapiens, involving few if any further biological changes.

Cognitive lecture at ELTE

by Lorincz, Andras

Hasonloan a Cognitive Center holland diakoknak (angolul) tartott eloadasaahoz egy eloadas lesz az ELTE-n is. Mindenkit szeretettel varok. Lorincz Andras http://people.inf.elte.hu/lorincz Cim: Is neocortical encoding of sensory information intelligent? Eloado: Lorincz, Andras Abstract: The theory of computational complexity is used to underpin a recent model of neocortical sensory processing. We argue that encoding into reconstruction networks is appealing for communicating agents using Hebbian learning and working on hard combinatorial problems, which are easy to verify. The model allows us to provide a computational definition for the concept of intelligence. Simulations illustrate the idea. Motivation for reconstruction network models: According to one view , intelligent agents learn by developing categories (Harnad, 2003). For example, mushroom-categories could be learned in two different ways: (1) by sensorimotor toil, that is, by trial-and-error learning with feedback from the consequences of errors, or (2) by communication, called linguistic theft, that is, by learning from overhearing the category described. Our point is that case (2) requires mental verification: Without mental verification trial-by-error learning is still a necessity. In our model, 'mental verification' shall play a central role for constructing the subsystems, our agents. Idopont es hely: Date: 16 April, 2004 Time: 10:00-12:00 A.M. Place: Room 0-823 (Kitaibel Room, ground level) West side of the South Building of ELTE (Danube is on the East side) Pazmany Peter setany 1/C

Please distribute this to anyone who might be interested. Yours sincerely, Paul Vogt This text is also available at http://www.tilburguniversity.nl/employees/cml/vacancies/8100406.html. Tilburg University is a specialized institute of learning and research, with emphasis on social sciences and the humanities. It employs more than 1600 people and has a student body of around 10,000. There are 19 colleges and 10 research institutes, which provide (postgraduate) tuition and research of outstanding quality. *Faculty of Arts* In its education and research programme, the Faculty of Arts addresses socially relevant domains in the field of language, communication, information and literary culture. Important areas of interest are business communication and digital media, discourse studies, multilingualism in a multicultural society, culture and literature, linguistics and artificial intelligence. The section Computational Linguistics at Tilburg University (The Netherlands) has, subject to the availability of financial resources, a position available for a: *RESEARCHER ON LANGUAGE EVOLUTION AND COMPUTATION (POSTDOC)* (m/f, 38 hours a week, vacancy number 810.04.06) *Project information* The section Computational Linguistics at Tilburg University might receive funding for 3 years for a postdoctoral researcher, starting 1 June 2004. The funding is part of a project entitled 'New and Emergent World Models Through Individual, Evolutionary, and Social Learning' (NEW TIES). This project is funded by the European Commission and is a joint project with researchers from the Vrije Universiteit Amsterdam (The Netherlands), Napier University (Edinburgh, UK), University of Surrey (UK), Eotvos Lorand University (Budapest, Hungary) and Tilburg University. See http://www.cs.vu.nl/~gusz/newties/newties.html <http://www.cs.vu.nl/%7Egusz/newties/newties.html> for the project home-page. NEW TIES is a highly ambitious project that aims at simulating the evolution of cultures in large populations of multi-agent systems through indivudual and social learning of, e.g., behavioural skills and language. The experiments will be set in a large computer network based on peer-to-peer technology and another part of the project will focus on monitoring how the culture (including language) evolves. Central to this project is the part that studies evolution of communication, language and cooperation in a large scale multi-agent society. The researcher in Tilburg will be responsible for implementing this central part. *Main tasks* The researcher's task will focus on the design of computational experiments concerning the origins and evolution of communication, language and cooperation. These experiments will have to be carried out both as a stand alone experiment and integrated with the contribution of the other partners in the project. Important areas within the research are scalability, the symbol grounding problem, the emergence of communication as such and the origins of grammatical structures as described in workpackage 3 of the project proposal (http://www.cs.vu.nl/~gusz/newties/newties.html <http://www.cs.vu.nl/%7Egusz/newties/newties.html>). Part of the research will be carried out in Edinburgh. In addition, the researcher will be responsible for the local organisation of the computer network (not necessarily the computer support). *Profile* The ideal candidate is an enthousiastic instigator and has a strong background in language evolution and computation, modelling multi-agent systems (preferably language models), evolutionary computation, machine learning, linguistics and/or psycholinguistics. Java programming skills are a further advantage. The candidate should have finished (or is about to finish) his/her Ph.D. in the field of artificial intelligence, artificial life, computational linguistics or another relevant area with the cognitive sciences. *Terms of employment* The collective labour agreement of Tilburg University applies. The selected candidate will get a three years contract (full-time). Pay classification is according to level of experience and expertise, with a minimum of 2.179,-- and a maximum of 3.453,-- euro per month (salary scale 10). Furthermore, the usual facilities (desk, computer, some travel money) are offered, as well as support with housing, immigrations, etc. *Information* For further information, please contact Dr. Paul Vogt email: p.a.vogt(a)uvt.nl <mailto:p.a.vogt@uvt.nl>, http://www.ling.ed.ac.uk/~paulv <http://www.ling.ed.ac.uk/%7Epaulv> or consult the project's home page http://www.cs.vu.nl/~gusz/newties/newties.html <http://www.cs.vu.nl/%7Egusz/newties/newties.html> *Applications* Interested candidates should send in their application and CV before 26 April 2004 to: Tilburg University, Faculty of Arts, O.M.

Depue and Jeannine V. Morrone-Strupinsky ABSTRACT: Because little is known about the human trait of affiliation, we provide a novel neurobehavioral model of affiliative bonding. Discussion is organized around processes of reward and memory formation that occur during approach and consummatory phases of affiliation. Appetitive and consummatory reward processes are mediated independently by the activity of the ventral tegmental area (VTA) dopamine (DA)nucleus accumbens shell (NAS) pathway and the central corticolimbic projections of the u-opiate system of the medial basal arcuate nucleus, respectively, although these two projection systems functionally interact across time. We next explicate the manner in which DA and glutamate interact in both the VTA and NAS to form incentive-encoded contextual memory ensembles that are predictive of reward derived from affiliative objects. Affiliative stimuli, in particular, are incorporated within contextual ensembles predictive of affiliative reward via a) the binding of affiliative stimuli in the rostral circuit of the medial extended amygdala and subsequent transmission to the NAS shell; b) affiliative stimulus-induced opiate potentiation of DA processes in the VTA and NAS; and c) permissive or facilitatory effects of gonadal steroids, oxytocin (in interaction with DA), and vasopressin on (i) sensory, perceptual, and attentional processing of affiliative stimuli and (ii) formation of social memories. Among these various processes, we propose that the capacity to experience affiliative reward via opiate functioning has a disproportionate weight in determing individual differences in affiliation. We delineate sources of these individual differences, and provide the first human data that support an association between opiate functioning and variation in trait affiliation. KEYWORDS: affiliation, social bonds, social memory, personality, appetitive reward, consummatory reward, dopamine, u-opiates, oxytocin, vasopressin, corticolimbic-striatal networks FULL TEXT: http://www.bbsonline.org/Preprints/Depue-07232002/Referees/ ======================================================================= ======================================================================= *** SUPPLEMENTARY ANNOUNCEMENT *** (1) Call for Book Nominations for BBS Multiple Book Review In the past, Behavioral and Brain Sciences (BBS) had only been able to do 1-2 BBS multiple book treatments per year, because of our limited annual page quota.
