Language Evolution at the UK Cognitive Linguistics Conference

The UK Cognitive Linguistics Conference will be hosted at the University of Birmingham next year, July 27 to 30. This interdisciplinary conference is focused on the intersection between language and cognition, and it accepts submissions from all areas of linguistics, including experimental and computational research on language evolution, language origins, iconicity, and cognitive and functional approaches to historical linguistics.
The plenary speakers for this conference include Adele Goldberg (Princeton University), Caroline Rowland (MPI Nijmegen), Mark Dingemanse (Radboud University) and Gabriella Vigliocco (University College London).

The call for papers is online, with a December 30 deadline for 500 word abstracts.

Besides submitting to the main session, the conference organizers welcome proposals for pre-conference workshops, which can be skills-based workshops lead by single researchers or teams of researchers, as well as series of talks by different researchers on specific topics.

Call for Contributions: Public Engagement in Language Evolution session

Next year at EvoLang, I’m doing a short session on public engagement in Language Evolution. As part of this, I have been given a small part of the poster session to have a little exhibition/discussion corner about public engagement initiatives. As such, I am now recruiting contributions that outline existing initiatives. Contributions will use the 2-page EvoLang template (available here: https://www.evolang.org/submissions). Contributions should outline the initiative and make clear:

  • The objective(s) for the public engagement initiative
  • Reflections on success and areas for improvement
  • Good practice to be learnt from these reflections

Contributions will be reviewed in relation to space constraints, but I hope to have a good diversity of examples. Please email contributions to hannah.little@uwe.ac.uk before January 3rd 2020. Questions to the same address.

More context of the session is below:

Public engagement has always been an important aspect of academia. Breaking the barrier between research and the public can foster knowledge, equality, trust and accountability. On a more pragmatic level, funders increasingly require impact statements and plans for public dissemination. However, language evolution as a field has unique difficulties meeting these demands.

Evolutionary linguistics is difficult to explain to those outside the field. Much research presented at EvoLang has implications for our knowledge of human origins, but the implications for current and future humans often remain unclear, creating a “relevance gap”. Further, the abstractness of research based on models (computational or experimental) and not referring to concrete artefacts, fossils or living examples, creates another barrier for explanation. Since EvoLang started, many researchers have undertaken public engagement initiatives that address this relevance gap in different ways. 

In this session, we will explore existing and future objectives for public engagement with language evolution research. We will discuss ways to frame language evolution to make it accessible to the public, and present examples of good practice, as well as lessons to be learnt, from previous and ongoing public engagement initiatives.

Initiatives will be split into 2 sections, mirroring two (non comprehensive) models for public engagement: deficit and participation (Trench, 2008).

The deficit model sees the public as having a knowledge deficit and seeks to fix that through one-way communication. Typical examples are documentaries (e.g. Through the Wormhole episode “How do Aliens Think”, Sayenga, 2013) and science journalism (e.g. Babel Magazine, Little, 2018). Discussion within the session will focus on good practice around creating relevant and intuitive explanations for concepts within language evolution.

The participation model works on the principle that all participants in a public engagement initiative can contribute, and that all have a stake in the outcome. Many public engagement initiatives in language evolution have recruited members of the public as participants in data-collection exercises at public events including festivals (e.g. Verhoef et al., 2015), science centres and museums (e.g. Cluskley, 2018; Raviv & Arnon, 2018), or as games (e.g. The Color Game, Morin et al., 2018). While involvement as an experimental participant is a contribution, it does not necessarily create a sense of having a stake in the outcome, or even understanding the outcome. Therefore one of the key aspects of the session will be discussing good practice for increasing public understanding around these initiatives.

As a result of the submissions, a collaborative review paper of initiatives and best practice for public engagement in language evolution may be produced for submission to the Journal of Language Evolution. If you’d like to contribute to this, but cannot contribute to the session, please email me on hannah.little@uwe.ac.uk

Four positions at the School of Collective Intelligence

Recently I was fortunate enough to go out to Morocco for the launch of a brand new school of Collective Intelligence:

If the launch was anything to go by, it’s going to be a pretty awesome to place to live and work, which brings me to four exciting opportunities for potential professors in data science, social computing, developmental psychology, and cognitive science:

The University Mohammed VI Polytechnic (Ben Guerir, Morocco) is recruiting one to three professors of cognitive sciences for October 2019 (at the earliest) […]

The recruited professors will divide their time between teaching (max. 3 courses per year), basic research, and applied research, in varying proportions depending on the position. Teaching will be in English or French.

Below are links to each of the positions (.docx) with more information.

Post-doc position at the Mint lab (Max Planck for the Science of Human History)

A new post-doc position has opened up at the Minds and Traditions research group in Jena, Germany (deadline: September 10th 2019). There are two possible projects (see links for more detailed descriptions):

  • How to value cultural diversity cultural diversity (link: https://www.dropbox.com/sh/eqfd9hmekoq0nav/AABWk1LCd_xkUh4mSE-8BTKqa?dl=0&preview=MintCultDivPostodc.pdf)
  • Measuring the distinctiveness of graphic symbols (link: https://www.dropbox.com/sh/eqfd9hmekoq0nav/AABWk1LCd_xkUh4mSE-8BTKqa?dl=0&preview=MintSymbolsPostDoc.pdf)

Having been here for the past four years I can vouch that the Mint is a pretty awesome place to work at.

New positions (PhD and Postdoc) at VUB AI Lab

Bart de Boer at the VUB A.I. Lab is looking for a new PhD student to work on agent based models:

The PhD work will consist of building an agent-based simulation in which we can investigate emergence of behavior in a cognitively realistic setting. This means that the agents are not fully rational and that they show behavior similar to that of humans, and that interests of agents are not necessarily always aligned. The modeling will primarily focus on emergence of speech, but the simulation should be general enough that it can be easily adapted to other areas, such as traffic or economic interactions.

More details and how to apply here: https://ai.vub.ac.be/node/1688

He’s also recruiting a visiting post-doc:

The work should consist of agent-based simulation, or of experiments to investigate emergence of behavior in a cognitively realistic setting. This means that in a computer simulation, the agents are not fully rational and that they show behavior similar to that of humans, and that interests of agents are not necessarily always aligned. Experiments should focus on factors that are typical for human settings, but that are generally idealized away, such as altruism, conflicts of interests and other “non-rational” behaviors. We are most interested in modeling emergence of speech, but we welcome applications proposing other areas, such as traffic or economic interactions.

Evolution: Is sex really even sexual?

This is a guest post by Angarika Deb.

Sexual Selection theory, though much celebrated, has faced criticism since its inception. A new model now proposes sexual reproduction and reproductive social behaviour to be cooperative instead of competitive, as was initially advocated earlier by Darwin.

After the sensational theory of natural selection, Darwin outlined the theory of sexual selection in his book, The Origin of Species (Darwin, 1869) and developed it in The Descent of Man and Selection in Relation to Sex (Darwin, 1871). This was in an effort to explain the structural and behavioural peculiarities in animals that did not make complete sense under the light of natural selection, for example ornamented plumage, mate signalling under predation risk etc. Natural selection is dependent on a struggle for enhancing individual survival; whereas sexual selection advocates a struggle between the sexes (intersexual competition) and amongst them (intrasexual competition) for rearing maximum progeny. ‘The result is not death to the unsuccessful competitor, but few or no offspring’, as explained by Darwin (1871). Heritable traits that are deemed detrimental to survival, were explained by sexual selection as conferring an advantage in intrasexual competition for finding mates and intersexual competition between mates to increase their own future reproductive fitness.

CfP: New directions in language evolution research (Special Issue of “Language Dynamics and Change”)

A couple of months ago, Peeter Tinits, Jonas Nölle and I organized a theme session with the fairly generic title “New directions in language evolution research” at the SLE conference in Tartu. Now we are planning a Special Issue of the journal “Language Dynamics and Change” (LDC) that covers the topics addressed at the workshop (and perhaps a few more). Our goal is to emphasize the “New Directions” aspect, i.e. to gather really innovative approaches to the evolution of language. We would like to open up the CfP beyond the circle of workshop participants – so everybody interested is invited to submit an abstract, on the basis of which we will make a first selection and invite full papers. Note that if we can’t include your paper in the Special Issue, you can of course still submit it as a regular paper to LDC. If you are interested in contributing, please send an abstract to newdir.langev@gmail.com until December 15th.

Here’s the description of our theme session again:

Research on language evolution is undoubtedly among the fastest-growing topics in linguistics. This is not a coincidence: While scholars have always been interested in the origin and evolution of language, it is only now that many questions can be addressed empirically drawing on a wealth of data and a multitude of methodological approaches developed in the different disciplines that try to find answers to what has been called “the hardest problem in science” (Christiansen & Kirby 2003). Importantly, any theory of how language may have emerged requires a solid understanding of how language and other communication systems work. As such, the questions in language evolution research are manifold and interface in multiple ways with key open questions in historical and theoretical linguistics: What exactly makes human language unique compared to animal communication systems? How do cognition, communication and transmission shape grammar? Which factors can explain linguistic diversity? How and why do languages change? To what extent is thestructure of language(s) shaped by extra-linguistic, environmental factors?

Over the last 20 years or so, evolutionary linguistics has set out to find answers to these and many more questions. As, e.g., Dediu & De Boer (2016) have noted, the field of language evolution research is currently coming of age, and it has developed a rich toolkit of widely-adopted methods both for comparative research, which investigates the commonalities and differences between human language and animal communication systems, and for studying the cumulative cultural evolution of sign systems in experimental settings, including both computational and behavioral approaches (see e.g. Tallerman & Gibson 2012; Fitch 2017). In addition, large-scale typological studies have gained importance in recent research on language evolution (e.g. Evans 2010).

The goal of this workshop is to discuss innovative theoretical and methodological approaches that go beyond the current state of the art by proposing and empirically testing new hypotheses, by developing new or refining existing methods for thestudy of language evolution, and/or by reinterpreting the available evidence inthe light of innovative theoretical frameworks. In this vein, our workshop aims at bringing together researchers from multiple disciplines and theoretical backgrounds to discuss the latest developments in language evolution research. Topics include

– experimental approaches investigating the emergence and/or development of sign systems in frameworks such as experimental semiotics (e.g. Galantucci & Garrod 2010) or artificial language learning (e.g. Kirby et al. 2014);

– empirical research on non-human communication systems as well as comparative research on animal cognition with respect to its relevance for the evolution of cognitive prerequisites for fully-fledged human language (Kirby 2017);

– approaches using computational modelling and robotics (Steels 2011) in order to investigate problems like the grounding of symbol systems in non-symbolic representations (Harnad 1990), the emergence of the particular features that make human language unique (Kirby2017, Smith 2014), or the question to what extent these features are domain-specific, i.e. evolved by natural selection for a specifically linguistic function (Culbertson & Kirby 2016);

– research that explicitly combines expertise from multiple different disciplines, e.g. typology and neurolinguistics (Bickel et al. 2015); genomics, archaeology, and linguistics (Pakendorf 2014, Theofanopoulou et al. 2017); comparative biology and philosophy of language (Moore 2016); and many more.

This latter trend to cross disciplinary boundaries is also evident in the proposed workshop contributions listed below. For instance, many of them approach long-standing questions from historical-typological linguistics from an evolutionary point of view by combining analyses of large typological databases with computational modelling, focusing on the emergence of (near-)universal patterns or the much-discussed topic of a potential connection between group size andlinguistic complexity. Others draw on insights from biology to discuss how thehuman capacity for language came about. What all have in common, however, is that they combine multiple perspectives to shed new light on the question of how language evolved and continues to evolve.

Why are we standing naked?

This is a guest post by Angarika Deb.

In a lineage of ancestors, humans are the only species left without a coat of body hair. Keeping in mind thermoregulation of bare skin, we speculate conditions for evolution of nakedness. Can it be coupled with bipedality?

The modifiers of evolution itself, are we Homo sapiens any closer to understanding our own emergence yet?

One of the salient features of the Mammals group is possession of body hair. Well, most of them at least. But we stand living proof against that. How, where and why did our body hair disappear and nakedness evolve? While Darwin argued that nakedness evolved for sexual ornamental purposes, Andersson[3] disagrees on the premise that, if sexual traits like a shiny plumage are indicative of good health, skin devoid of hair would convey poor health and won’t attract mates. It is important to determine the initial step of this denudation. A coat of body hair prevents too much heat reaching the body in daytime as well as shielding from cold at night. Protection from wind, wounds, bites, and UV radiation also feature in the advantages. Why then, did Homo sapiens end up losing one great layer of protection? If one believes in ‘Survival of the Fittest’, the benefits stemming from near disappearance of human body hair must surely be great enough to outweigh the costs of these protective functions. The repository of hypotheses trying to explain this step of evolution is still growing.

The EvoLang Causal Graph Challenge

This year at EvoLang, I’m releasing CHIELD: The Causal Hypotheses in Evolutionary Linguistics Database.  It’s a collection of theories about the evolution of language, expressed as causal graphs.  The aim of CHIELD is to build a comprehensive overview of evolutionary approaches to language.  Hopefully it’ll help us find competing and supporting evidence, link hypotheses together into bigger theories and generally help make our ideas more transparent. You can access CHIELD right now, but hang around for details of the challenges.

The first thing that CHIELD can help express is the (sometimes unexpected) causal complexity of theories.  For example, Dunbar (2004) suggests that gossip replaced physical grooming in humans to support increasingly complicated social interactions in larger groups.  However, the whole theory is actually composed of 29 links, involving predation risk, endorphins and resource density:

The graph above might seem very complicated, but it was actually constructed just by going through the text of Dunbar (2004) and recording each claim about variables that were causally linked.  By dividing the theory into individual links it becomes easier to think about each part.

Second, CHIELD also helps find other theories that intersect with this one through variables like theory of mind, population size or the problem of freeriders, so you can also use CHIELD to explore multiple documents at once.  For example, here are all the connections that link population size and morphological complexity (9 papers so far in the database):

The first thing to notice is that there are multiple hypotheses about how population size and morphological complexity are linked.  We can also see at a glance that there are different types of evidence for each link.  Some are supported from multiple studies and methods, while others are currently just hypotheses without direct evidence.

However, CHIELD won’t work without your help!  CHIELD has built-in tools for you – yes YOU – to contribute.  You can edit data, discuss problems and add your own hypotheses.  It’s far from perfect and of course there will be disagreements.  But hopefully it will lead to productive discussions and a more cohesive field.

Which brings us to the challenges …

The EvoLang Causal Graph challenge: Contribute your own hypotheses

You can add data to CHIELD using the web interface.  The challenge is to draw your EvoLang paper as a causal graph.  It’s fun!  The first two papers to be contributed will become part of my poster at EvoLang.

Here are some tips:

  • Break down your hypothesis into individual causal links.
  • Try to use existing variable names, so that your hypothesis connects to other work.  You can find a list of variables here, or the web interface will suggest some.  But don’t be afraid to add new variables.
  • Try to add direct quotes from the paper to the “Notes” field to support the link.
  • If your paper is already included, do you agree about the interpretation? If not, you can raise an issue or edit the data yourself.

More help is available here.  Click here to add data now!  Your data will become available on CHIELD, and your name will be added to the list of contributors.

Bonus Challenge: Contribute 5 papers, become a co-author!

I’ll be writing an article about the database and some initial findings for the Journal of Language Evolution.  If you contribute 5 papers or more, then you’ll be added as a co-author.  As an incentive to contribute further, co-authors will be ordered by the number of papers they contribute.  This offer is open to anyone studying evolutionary linguistics, not just people presenting at EvoLang.  You should check first whether the paper you want to add has already been included.

Bonus Challenge: Contribute some code, become a co-author!

CHIELD is open source.  The GitHub repository for CHIELD has some outstanding issues. If you contribute some programming to address them, you’ll become a co-author on the journal article.
