The Howard Hughes Medical Institute has joined forces with the Simons Foundation and the Bill & Melinda Gates Foundation to support a new grant program for early career scholars at eligible US institutions: the Faculty Scholars Program. “The competition is open to basic researchers and physician scientists at more than 220 eligible U.S. institutions. Applicants must be using molecular, genetic, computational or theoretical approaches to address fundamental biological or biomedical problems. Applicants must have more than four but fewer than 10 years of post-training professional experience.” The application to be submitted has some interesting components. For example, it asks for a statement of how the applicant’s work differs from that of his or her mentors and a statement about collaborative networks the applicant is part of. It’s also clear that in order to be successful with grants like this, an applicant has to have a well-articulated research program. I imagine that, in the area of language, it would not do to do experimental or field-based work on this or that semantic phenomenon. There would have to be a bigger theoretical question in the background that this work contributes to. I imagine that in the area of language, the question would have to be more specific than simply ‘language acquisition’ or ‘language processing’, but it would still have to be one that Bill or Melinda Gates might find fascinating and important. 

I hope that the SIAS Summer Institute that Manfred Krifka and I are convening this year at the Wissenschaftskolleg in Berlin and next year at the National Humanities Center in North Carolina may help participants to eventually be eligible for grants like this one. We are trying to foster collaborative projects centering around the major questions of linguistic meaning, supporting sophisticated formalized theories with all the evidence we can find for them, including evidence from neuroscience, cognitive psychology, cross-linguistic variation, language development, learnability theories, and language processing.

I once asked a physicist friend why Stephen Hawking had never won the Nobel Prize. He looked startled and said: “You know, Hawking’s theories are beautiful, but they haven’t been proven yet. Higgs only got a nobel prize once the Higgs boson was actually found.” In the area of quasicrystals, a nobel prize in chemistry was given to the person who discovered (a synthesized) one (Dan Shechtman), rather than to the people who provided the proof that quasicrystals were mathematically possible to begin with (Dov Levine & Paul Steinhardt).

The most interesting linguistic theories are about the human language faculty, hence about a biological phenomenon. If we want to sell our theories of linguistic meaning as biological theories, we have to connect them to a certain level of reality. We are not quite there yet. But the right kind of research is beginning to emerge. Jorie Koster-Hale’s 2014 PhD thesis is an example. To quote from the previous post, “the most exciting and creative parts of science are concerned with things that we are still struggling to understand. Wrong theories are not an impediment to the progress of science. They are a central part of the struggle.” This means that THEORIES are an important part of the struggle, but they are just a PART.  

The case for blunders

brilliant-blundersFrom the review of Livio’s book by Freeman Dyson in the New York Review of Books, March 6, 2014:

Brilliant Blunders by Mario Livio, is a lively account of five wrong theories proposed by five great scientists during the last two centuries. These examples give for nonexpert readers a good picture of the way science works. The inventor of a brilliant idea cannot tell whether it is right or wrong. Livio quotes the psychologist Daniel Kahneman describing how theories are born: “We can’t live in a state of perpetual doubt, so we make up the best story possible and we live as if the story were true.” A theory that began as a wild guess ends as a firm belief.”

“The essential point of Livio’s book is to show the passionate pursuit of wrong theories as a part of the normal development of science. Science is not concerned only with things that we understand. The most exciting and creative parts of science are concerned with things that we are still struggling to understand. Wrong theories are not an impediment to the progress of science. They are a central part of the struggle.”

Clever fish

Nature, 26 May 2015. Animal behavior: Inside the cunning, caring, and greedy minds of fish. This is an article describing the remarkable discoveries about fish intelligence made by behavioral ecologist Redouan Bshary.

“Primate chauvinism may now be poised to decline, thanks in large part to Bshary’s fish work,” says primatologist and ethologist Frans de Waal of Emory University in Atlanta, Georgia. “They now really do have to take on board that most species are going to have a type of smart intelligence.”

“Redouan has thrown down the gauntlet to us primatologists,” says Carel van Schaik, an expert in orang-utan culture at the University of Zurich in Switzerland. “He has made us realize that some of the explanations of primate intelligence that we have cherished don’t hold water anymore.”

The word “cooperation” covers a wide range of rather different behaviors, though. Here is a video on what human toddlers and chimps can do in the way of cooperation. I yet have to see a fish recognize what I am trying to do and come to my help.

Robert Stalnaker

Robert-Stalnaker-MIT_0

From MIT News Office

“While working in a famously esoteric field, MIT philosopher Robert Stalnaker has focused his career on thinking about real-world concerns — including the fundamental nature of speech, thought, and decision-making. In so doing, he has catalyzed and provided the underpinnings for new research in many other areas, such as game theory, linguistics, decision theory, and economics. In all these research areas, Stalnaker’s influence has been widespread and profound, but his impact on modern linguistics — a field that was just coming into its own in the 1970s — has been especially significant, providing the first clear understanding of what is going on in conditional sentences that are counterfactual.”

Moving beyond Big Data

“The National Science Foundation has announced that the University of Maryland’s Language Science Center (LSC) will (again!) receive a $3M grant for innovative research and graduate training, this time as part of the first cohort of awards made through its new NSF Research Traineeship (NRT) program. This 5-year award will support a model of interdisciplinary graduate training that prepares students to be adaptable scientists in multiple settings and career paths. The project will connect research on humans and machines, via a focus on how to succeed when Big Data is not available. The project is led by faculty and students from 10 departments across the entire university.”

“I’m excited by the research theme, which takes a “Beyond Big Data” approach,” says Colin Phillips, program PI and LSC Director. “We’re interested in how humans and machines can learn more efficiently from ‘multi-scale data’. Everybody’s talking these days about Big Data, but the current frontier in language science involves how to do more with less, you could call it ‘medium data’ or ‘small data’. It’s important for building better language technology, and it’s important for improving language learning outcomes in children and adults. Current language technologies like Google Translate and Apple’s Siri rely on a Big Data approach that stores billions of utterances. But that approach won’t generalize to the vast majority of the world’s 7000 languages. And human children easily outperform the best current technology, though they learn language from far less data. Child brains somehow learn the language around them more efficiently. But we all know that learning a new language as an adult is much harder. And we’re learning more and more about how children who experience ‘language poverty’, growing up with smaller amounts of quality language interaction, face negative consequences that last a lifetime. We want to understand why some learners fare better than others.” A key venue for exploring the program’s research goals will be yearly “Summer Camps”, intensive research-only workshops that will bring together students and faculty from UMD and beyond.”

Thomas Ede Zimmermann

From the Linguist List: “Becoming a semanticist back in the 1970s was quite different from what it is in the days of Heim & Kratzer (incidentally, two of my old Konstanz friends). The field had not been established as a sub-discipline of linguistics, and despite some serious integrative attempts (thanks to Barbara Partee), it was still perceived as an esoteric pastime of a small community of logicians, philosophers of language, and (few) linguists. In Germany, this community was particularly strong, with enough funding to have spectacular conferences bringing together some of the best researchers in the field. I attended quite a few of them, though rarely presenting anything, during the time I worked on my dissertation, which was supposed to be about the interface between logical and lexical semantics. I never finished that dissertation, for at least two reasons. The first was that I kept changing my mind over the very subject area: my original strategy had been to formulate model-theoretic constraints on meaning postulates to keep them from overgenerating (a serious issue at the time, and still), but the more I worked on it, the less confident I became that model theory is the right framework for natural language semantics. The other reason was that I was easily distracted, working on a lot of other problems at the same time, and with more success (in terms of publications). One of my favourite topics was Groenendijk’s and Stokhof’s fascinating partition semantics of interrogatives. When investigating its logical underpinnings, I found that one of Montague’s implicit hypotheses about semantic analysis – that his intensional type logic provides a restrictive framework of compositional semantics – was not quite right. I wrote a short article about this and showed it to my would-be supervisor Arnim von Stechow, who saw to it that I would submit it as my dissertation. In the event it was accepted by him (and the co-promoters) and also got published in a logic journal. Rather than being proud of these 13 pages in print, I have always felt a bit ashamed for never having written a proper dissertation; but in the meantime I got used to being introduced as the guy who must have written the shortest linguistics dissertation ever.”

The amazing University of Konstanz

konstanz-conference-1978_Page_01

In 1978, semanticists at the University of Konstanz organized a memorable interdisciplinary conference “Semantics from Different Points of View”, bringing together linguists, psychologists, philosophers, and computer scientists in a joint conference on the various ways of studying linguistic meaning. The photograph has Barbara Partee right in the middle (with unicorn shirt). Behind her are Ede Zimmermann and David Lewis. I am on the very left in the first row, next to Max Cresswell, who is next to Arnim von Stechow. In the last row, you see Irene Heim, who was then a graduate student at UMass Amherst, but had been a student of Arnim von Stechow’s in Konstanz before that. Next to Irene Heim is Hans Kamp. Among the other participants are Manfred Pinkal, Renate Bartsch, Dieter Wunderlich, Wolfgang Klein, Urs Egli, Josef Bayer, Rainer Bäuerle, Veronika Ehrich, Eckehard König, Joachim Ballweg, Roland Hausser, and Wolfgang Sternefeld.

I received all of my degrees from the University of Konstanz (MA and Dr. phil – there was no BA in Germany at the time). When I was a student and young researcher in Konstanz in the 1970s, this was an absolutely amazing place, and much of my success in my profession has its roots there. To mention just a few things: even though I was only in my 3rd year of university studies when I arrived in Konstanz (I would have been a mere undergraduate in the US), I was collaborating on a (long-forgotten) 2-volume book on mathematical linguistics after just one year there, and even became (undeservedly) the book’s first author. This wasn’t anything special about me: this was Konstanz in the 1970s. Roughly at the same time, I became one of three members of the Executive Committee running the Konstanz Linguistics department. I was the student member, but my voice had equal weight. I was also a member of the University’s Ausschuss für Lehrfragen (University Committee for Matters of Teaching) – half of the members of this committee were students, the other half were tenured and untenured faculty. The committee was in charge of all important issues relating to teaching. I have been grateful for the education I received in Konstanz ever since – it was pure Utopia – something that wasn’t available anywhere else in Germany (or in the world).  

Mind-reading neurons

From MGH News:

“A study by Massachusetts General Hospital (MGH) investigators has discovered two groups of neurons that play key roles in social interactions between primates – one that is activated when deciding whether to cooperate with another individual and another group involved in predicting what the other will do.  Their findings appear in the March 12 issue of Cell.”

In this study, pairs of Rhesus monkeys repeatedly played a version of the Prisoner’s Dilemma game. The most remarkable result of the study is that the ‘predictor neurons’ of monkey A predicted the choices of monkey B as accurately as a ‘rational’ algorithm that tried to predict the choices of monkey B based on his/her prior choices. Here is a beautiful article on the Prisoner’s Dilemma and its role in Evolutionary Biology from Quanta Magazine

The Latin American School for Education, Cognitive and Neural Sciences (LASchool)

LA School

From the website of the 5th instantiation of the LASchool: LASchool is a meeting that brings together students and faculties from all over the world in Latin America “to build new bridges between Education, Cognitive and Neural Sciences. Each year, LASchool’s participants work together for two weeks to generate project proposals potentially relevant for the development, design and implementation of effective science-based educational practices. LASchool series have been inspired by the ideas raised in The Santiago Declaration, in 2007.”

“Previous LASchools took place in Atacama, Chile (2011), Patagonia, Argentina (2012), Bahia, Brazil (2013), and Punta del Este, Uruguay (2014). All these experiences have brought together more than 150 researchers and 200 students in a continuing effort to promote the scientific work at the interface between Education and Science.”

This 5th version of the LASchool is organized by the Cognitive Neuroscience Laboratory at Pontificia Universidad Católica de Chile and will take place in San Pedro de Atacama. The LASchool will develop several issues such as the transition from informal to formal education, how brain systems change through development and education, and how social programs may impact education.”

Logic and Grammar

botticelli

Sandro Botticelli: A Young Man Being Introduced to the Seven Liberal Arts

Why do I make my semantics students learn logic? I ask them to work through both volumes of the Gamut textbook, even though Gamut doesn’t speak the language of linguistics. It is written in the language of logic. Why should semantics students have to learn how to talk and reason in this way? There is a simple answer: In an interdisciplinary field everyone from any participating field has to speak the language of the other fields. That’s your entrance ticket for success in an interdisciplinary enterprise. You have to understand where the practitioners of other fields are coming from. As a relatively new interdisciplinary field, formal semantics has been a success. It is the result of the marriage of two highly formalized and abstract theories: Logic, which provides theories of the human notion of what a valid piece of reasoning is, and Syntax, which contributes theories of how hierarchical syntactic structures are computed in natural languages. The marriage is solid and has been going strong for almost 50 years. Many young linguists, logicians, and philosophers are fluent in three disciplines, and collaborate in joint research institutions, journals, and conferences.

You may have heard people say that theories of logic can’t be cognitive theories because people make logical mistakes. Yes, we all do make logical mistakes. What is important, though, is that, when we do, we can be convinced that we were wrong. How come? There must be a notion of what a valid piece of reasoning is that is the same for all human beings. Imagine what the world would be like if people all had different notions of what follows from what and what is or isn’t consistent. Mathematics would be impossible, science would be impossible, laws and contracts would be impossible, social institutions would be impossible, … For more than 2000 years, logicians have been designing theories of universally shared patterns of valid human reasoning. The resulting theories are among the most sophisticated theories science has produced to date. And they are the most sophisticated formal theories in cognitive science. One of the key insights of the early logicians was the discovery that little words like notandorsomeallmustmay, and so on are the main players in patterns of valid reasoning. That is, those patterns are created by properties of the functional (that is, logical) vocabularies of human languages. It’s precisely those vocabularies that also provide the scaffolding for syntactic structures. Syntax is about the hierarchical structures projected from the functional vocabularies of natural languages, Logic provides the models of how to study the meanings of those vocabularies and how to explain their role in reasoning. In formal semantics, those two disciplines have come together.

Contemporary modern semantics was born when the traditional perspectives of logic merged with the modern enterprise of generative syntax, as initiated by Noam Chomsky. The first worked out formal semantic system in this tradition was David Lewis’ 1970 paper General Semantics, one of the most beautiful and enjoyable articles in semantics to the present day. Lewis made an explicit connection with Chomsky’s Aspects model, the generative syntax model of the time. In contrast to Lewis, Richard Montague was outspokenly hostile to Chomsky’s work. He was not interested in Chomsky’s call for an explanatory syntax. It was only after Montague’s death that linguists like David Dowty, Lauri Karttunen, Barbara Partee, Stanley Peters, and Robert Wall made Montague’s works accessible to linguistic audiences.
