The illiterate brain

Illiteracy due to social reasons is unfortunately still frequent in several countries. To study the anatomy and physiology of the brain of illiterate volunteers, it is important to understand how the brain adapts to reading and writing. We will review studies done in past years showing the differences between literate and illiterate subjects.

Alexandre Castro-Caldas

Alexandre Castro-Caldas is Full Professor in Neurology and Director of the Institute of Health Sciences at the Portuguese Catholic University in Lisbon. He is the former Director of the Department of Neurology of the Santa Maria Hospital in Lisbon, as well as former President of the Portuguese Society of Neurology and the International Neuropsychological Society. Alexandre Castro-Caldas' main research interests include the neuro-cognitive foundations of language and mental health, Portuguese Sign Language, and education in neuropsychology. He is the author of more than 200 articles in neuropsychology as well as books and edited volumes on the brain, cognition, learning, aphasia, creativity, Alzheimer disease, and computer-assisted rehabilitation. In 2000, he was awarded the Bial Award in Biomedicine.

Ape Gesture: Signaling and meaning from the ape perspective

Language appears to be the most complex system of animal communication described to date. However, its precursors were present in the communication of our evolutionary ancestors and are likely shared by our modern ape cousins. All great apes, including humans, employ a rich repertoire of vocalizations, facial expressions, and gestures. Great ape gestural repertoires are particularly elaborate, with ape species employing over 80 different gesture types intentionally: that is towards a recipient with a specific goal in mind. Intentional usage allows us to ask not only what information is encoded in ape gestures, but what do apes mean when they use them. I will discuss recent research on ape gesture, including work on human infants. I will also explore how we can define signals and meaning from the perspective of the ape signalers using them. By employing an ape-centric approach we may be better able to describe their communicative capacities.

Catherine Hobaiter is Lecturer in Primate Behavior at the Origins of Mind group in the Department of Psychology and Neuroscience, at the University of St Andrews in St Andrews, Scotland. She has spent the past 14-years studying wild primates across Africa, in particular the chimpanzees of the Budongo Forest in Uganda. Through long-term field studies she explores what the behavior of great apes living in their natural environment tells us about their minds, and about the evolutionary origins of our own behavior. Her research interests include communication, in particular gestural communication, and social learning. She recently established the Great Ape Dictionary, an online site allowing scientists from around the world to access video archives of wild ape behavior, and citizen scientists to participant in online research. She is the co-director of the Bugoma Primate Conservation Project, and the Vice President of Communications for the International Primatological Society.

The Middle Paleolithic revolution

By the later Upper Paleolithic, all continents were occupied, all ecosystems were exploited, and all aspects of hunter-gatherer culture amenable to preservation in the archaeological record are found. Prior to the Last Inter-glacial, such is not the case. In an evolutionary time scale, a “revolution” thus occurred, but it was not an Upper Paleolithic one, as we now know that body painting, personal ornamentation, object decoration and formal burial date back to ~120,000 years ago, and that European cave art begins >65,000 years ago, which implies Neanderthal authorship. Only historical- and social-based, not cognitive- or human taxonomy-based explanations are consistent with this Middle Paleolithic revolution, which is best understood as a protracted process of technological improvement and demographic growth, combined in a feedback loop with developments towards more sophisticated modes of communication and social organization that bespeak of the emergence of ethnicity and ethnic boundedness.

João Zilhão

João Zilhão is ICREA Research Professor in Archaeology at the Department of History and Archaeology of the University of Barcelona in Spain, and research fellow at UNIARQ, the Archaeological Center of the University of Lisbon. His main research interests include the Middle-to-Upper Paleolithic transition, the fate of the Neanderthals, and the origins of art. In Portugal, he was appointed by the government to set up the Côa Valley Archaeological Park and he contributed to the site acquiring UNESCO World Heritage status; he directed the salvage excavation of the Early Upper Paleolithic child burial of the Lagar Velho rock shelter; and he created and directed the Instituto Português de Arqueologia (IPA), a department of the Ministry of Culture for the supervision of archaeological activity. He has also contributed to a more accurate dating of the cave art paintings in Northern Spain (World Heritage properties of El Castillo, Altamira and Tito Bustillo), and he has been involved in excavating the Romanian Peștera cu Oase cave that to date is the oldest settlement of modern humans in Europe.

Klaus Zuberbühler

Primate Language

How did human communication transition from an ancestral, primate-like communication system to modern human language? 40 years of field studies on primate communication have produced considerable progress towards a general theory of how human language evolved. I will examine seminal and ongoing research on primate communication with relevance for the origins of the language faculty, including the origins of meaning, syntax and social awareness. For some components evolutionary continuities are clearly visible, for others there are perplexing discontinuities, possibly rooted in differences in social intelligence and mere vocal control.

Klaus Zuberbühler is Professor in Biology at the Department of Comparative Cognition in the Institute of Biology at the University Neuchâtel in Neuchâtel, Switzerland; and Professor at the School of Psychology and Neuroscience of the University of St Andrews, UK. He is Scientific Director of the Budongo Conservation Field Station in Uganda; Co-director of the Tai Monkey Project in the Ivory Coast; and Director of the Biology Master Course at the University of Neuchâtel. His main research interests include the evolution of primate intelligence, combinatorial capacities, object manipulation, and intentional communication. He is on the Scientific Advisory Board of the Max Planck Institute for Evolutionary Anthropology, member of the International Primatological Society, fellow of the Wissenschaftskolleg Berlin, and Fellow of the Royal Society of Edinburgh.

A model for the emergence of recursive syntax

Why and how have human languages come to exploit recursive hierarchical structures? This is one of the key puzzles in the origins of language and it has given rise to enormous debate. Several competing theories have been put forward, including an appeal to genetics and explanations based on the presence of a learning bottleneck in cultural transmission. Here I argue that hierarchical structures get introduced by speakers in order to minimize the combinatorial complexity in semantic interpretation and avoid misunderstanding by hearers. Recursive hierarchical structure naturally emerges without any additional cognitive complexity when meanings containing objects are themselves used to introduce other objects (as in 'the block next to the ball left of the pyramid'). I will report on a minimal agent-based model that explores this hypothesis. The model proposes detailed mechanisms for the learning, invention, and processing of lexicons and grammars. Agents endowed with these mechanisms then play language games in a blocks world setting and expand, learn and align their grammars in consecutive language games. I will show that recursive grammars indeed emerge when the right cognitive mechanisms are chosen.

Luc Steels

Luc Steels is ICREA Research Professor in Artificial Intelligence at the Institute for Evolutionary Biology at the Universitat Pompeu Fabra in Barcelona, Spain. His main research interests include agent-based modeling of language emergence and evolution. With his team he has done a large series of experiments on the emergence of lexicons of perceptually grounded categories, in particular color, emergence of spatial terms and perspective, action terms, case grammar, agreement systems, and constituent structure. This work has resulted in a large number of publications (H-index = 69) and more than 15 edited volumes including the Talking Heads Experiment, Design Patterns and Computational Issues in Fluid Construction Grammar (the world’s most advanced computational platform for exploring constructional language processing), and Experiments in Cultural Language Evolution. He is the founding director of the Sony Computer Science Laboratory in Paris, co-founder of the European AI Association as well as co-founder and former president of the Belgian AI Association and the Evolutionary Linguistics Association.

Rafael Núñez

Biological enculturation: The primacy of symbolic reference in language evolution

Many ubiquitous abilities present in the recent history of humanity such as writing and reading, or piano playing and snowboarding, require the support of biologically evolved preconditions (BEPs)— e.g., visual or hearing acuity, finger movement differentiation, or a vestibular system that supports balance. These BEPs are neither precursors of such abilities, nor are they domain-specific. For these abilities to manifest, individual learning in ontogeny must occur in specific eco-historical niches that are heavily supported by cultural preoccupations, intentional social scaffolding, and material culture (pencils, pianos, snow gear). All of this largely unfolds outside of biological evolution, and could not occur without the crucial role of symbolic reference, which lacks both the natural associations and trans-generational reproductive consequences that would make such references biologically evolvable (Deacon, 2011). In this talk I will discuss the biological enculturation hypothesis, which states that the enculturation process underlying the above (and many other) abilities requires the guided recruitment and support of BEPs mediated by symbolic reference. I will analyze the crucial role that symbolic reference plays in taking BEPs to entire new (and perhaps discontinuous) levels in human evolution and focus on numerical cognition, temporal concepts, and declarative pointing and their relevance for understanding language evolution.

Rafael Núñez is Professor at the Department of Cognitive Sciences of the University of California, San Diego. Born and raised in Chile, he obtained his doctoral degree in Switzerland, and completed his post-doctoral work at Stanford and UC Berkeley. He investigates the development and evolution of everyday and technical cognition —especially conceptual systems, symbolization, and abstraction— and their biologically enculturated underpinnings. His multidisciplinary approach uses methods such as psycholinguistic experiments, gesture studies, brain imaging, and field research with isolated indigenous groups. His 2001 best-selling book, Where Mathematics Comes From: How the Embodied Mind Brings Mathematics into Being, and co-authored with UC Berkeley linguist George Lakoff, presents a new theoretical framework for understanding the human bio-cultural nature of mathematics and its foundations. Rafael Núñez is on the Scientific Advisory Board of the Australian Centre of Excellence for the Dynamics of Language, an active faculty member of the Center for Academic Research and Training in Anthropogeny (CARTA) devoted to promote transdisciplinary research into human origins, and fellow of the Wissenschaftskolleg Berlin.

A new approach to assessing the value of Basque as a tool for interpreting European prehistory

The talk brings forward a new approach to testing the validity of the assumption that the Basque language is a linguistic isolate and, more specifically, that it cannot shed light on the prehistory of languages classed as Indo-European. Researchers have stressed the structural stability of Basque, namely, that there is virtually no observable tendency for Indo-European morphological features to be transferred into Basque. What has not been tested is whether morphological features found in Basque have counterparts classed as Proto-Indo-European (PIE) morphemes. In the talk two sets of data are compared, one found in Basque and the other comprised of morphemes classed as PIE which are extensively attested across Indo-European languages.

Roslyn Frank

Roslyn M. Frank is Professor Emeritus in Spanish and Portuguese Linguistics at the University of Iowa, USA and Treasurer of SEAC, the European Society for Astronomy in Culture. Her research areas include cultural, cognitive, and historical linguistics as well as ethnography with a special emphasis on the Basque language and culture. She has also published extensively in the areas of ethnomathematics and ethnoastronomy. Over the past twenty years her publications have brought together ethnographic and linguistic evidence pointing to the existence of an archaic European belief, namely, that humans descended from bears, a belief retained by the Basques into the 20th century and reflected in a panoply of similar European folk-beliefs, ritual performances and practices.

On the structure of early language: Analytic vs holistic language processing and grammaticalization

Linguistic and neuroanatomical evidence indicates the existence of two modes of processing in linguistic discourse, namely an analytic mode and a holistic mode. Competent language users know many linguistic entities in two ways: holistically and analytically, and can move between the two. The analytic mode is concerned with propositional language processing based on the compositional format of sentences, clauses, phrases and their hierarchical organization, while the holistic mode surfaces in unanalyzable, formulaic expressions, e.g. in speech act formulas such as interjections (wow, ouch), ideophones (bang, splish-splash), formulae of social exchange (hello, sorry). Research on the reconstruction of earlier stages of language evolution has for the most part been restricted to the analytic mode, and grammaticalization theory played an important role in this research. The talk will demonstrate that a complementary analysis of holistic ways of processing can contribute to a more comprehensive understanding of how human languages may have evolved.

Tania Kuteva is Professor in English Linguistics at the Institute for English and American Studies in the English Linguistics Department at the Heinrich-Heine University in Düsseldorf, Germany, and a Professorial Research Associate of the Linguistics Department of SOAS, University of London, UK. Her main research interests include grammaticalization, language contact, discourse grammar, linguistic typology and the evolution of language. She is an Expert Assessor for the European Research Council (ERC) within the Framework Program for Research and Innovation (Horizon 2020), and Member of the Cognitive Linguistics Society, the German Society of Linguistics, the Association for Linguistic Typology, and the Linguistic Society of America.

Evolution of the human mind viewed from the study of chimpanzees

Humans and chimpanzees are similar at early developmental stages, however, there remain several crucial differences. Young chimpanzees possess exceptional working-memory capacities superior to those of human adults. But their ability to learn the meaning of symbols is relatively poor. In comparison to humans, chimpanzees are also poor in social-referencing abilities and they rarely engage in general imitation and active teaching. Based on parallel efforts in the field and laboratory, I present possible evolutionary and ontogenetic explanations for aspects of cognition that are uniquely human. The human neonate is characterized by a stable supine-posture that enables face-to-face communication via facial expressions, vocal exchange, gestures, and object manipulation. This is called the “Cognitive Tradeoff hypothesis”, that investigates the tradeoff between language and memory.

Tetsuro Matsuzawa

Tetsuro Matsuzawa is Distinguished Professor at the Institute of Advanced Study at the Kyoto University in Japan and General Director of the Japan Monkey Centre in Inuyama, Aichi, Japan. His main research interests include chimpanzee intelligence both in the laboratory and in the wild. The laboratory work is known as the “Ai-project” and it has been conducted since 1976 at the Primate Research Institute of Kyoto University. He has also been studying tool use in wild chimpanzees at Bossou-Nimba, Guinea, West Africa, since 1986. Matsuzawa tries to synthesize the field and the lab work to understand the nature of chimpanzees.
