Description

 

The idea that complexity plays a role in explaining why language is the way it is has a long history in linguistics. The relationship between complexity and explanation will be the focus of this seminar. Complexity is often suspected of being responsible for aspects of typological variation (e.g. universals, quasi-universals, implicational universals, asymmetries and gaps), constraints on rules of grammar, language change, the course of language development, and language processing. In order to make such an approach to explanation work, it is necessary to formulate a notion of complexity with some precision. Doing so then allows us to ask whether it is possible to attain a genuine explanation of some phenomenon, and whether the same notion of complexity is applicable to a range of different cases.

 

This seminar will survey the potential role of grammatical complexity in explaining why languages have certain properties and not others. The goal will be to understand what factors contribute to grammatical complexity and how complexity might explain why certain aspects of language are universal or almost universal, why certain aspects are relatively rare, and why many logical possibilities do not occur at all.

 

The research that relates to this issue comes from many areas, including grammatical theory, language processing, language acquisition, computation, and typology. It will be very exciting to try to determine to what extent it is possible to tie these things together in order to understand how things work.

 

One theme will be the role of complexity in accounting for universals, variation and change. Our goal will be to understand what the factors are that might contribute to grammatical complexity and how complexity may explain why certain aspects of language are universal, why certain aspects are relatively rare, and why many logical possibilities do not occur at all.

 

Another theme will be linguistic constructions. Intuitively, specialized constructions are more complex than fully regular constructions (which sometimes are characterized in terms of rules). Where do they come from, and what happens to them over time? We will consider the extent to which the properties of constructions can be accounted for in terms of general principles, how they are acquired, their status vis-à-vis rules, how they change over time, their status in a formal grammar, and how their complexity can be measured.

 

A third theme will be the role of complexity in accounting for the unacceptability of otherwise well-formed expressions of a language. There is a long history of research along these lines for center-embedding and similar cases that are intuitively difficult to process. We will see to what extent such an approach can be extended to novel cases.

 

Anyone who is interested in exploring explanations for grammatical phenomena from any of these perspectives will be very welcome. Students who are doing research on grammatical description, the architecture of the grammar, grammatical processing, contact or grammatical change are encouraged to participate in this seminar and explore the questions that we will be addressing with respect to their own work. Students who are working in phonology may also want to consider participating, to the extent that they see the opportunity to relate some of the issues that we will be looking at to their own work.

                        Expectations

Students will be expected to actively participate in the discussion and research carried out in the seminar. As explained below, students will be required to facilitate discussions and post questions on the readings in advance. Students will either initiate a research project that deals with some aspect of complexity and explanation in grammatical theory, or for students already working on a related topic, related these issues to their own research (and vice versa).

                        Prerequisites

 

Contrary to the generic course description, the prerequisite for this seminar is Ling 602.01, not Ling 602.02, or permission of the instructor.

 

                        Carmen

 

We’ll use Carmen to post questions and provoke discussion. Most of the readings will reside on Carmen, as well, in order to guarantee uniform access to them.

 

Requirements

                        Class participation (20%)

I would like for us to have a seminar in which everyone participates in a lively and constructive discussion of the readings. Thus, I plan on taking a page from Mike White and Erhard Hinrichs playbook, who took a page from Eric Fosler-Lussier's playbook, as follows. Everyone will be required to post at least one question to the discussion list on Carmen by 8 p.m. the evening before the assigned readings will be discussed. Participants are also encouraged to share their (initial) thoughts and views of the papers in their posts, and to ask questions where things are not clear. As always, if something is not clear to someone, it is probably not clear to lost of other people, so highlighting these issues is a great service.

                        Facilitating discussions (30%)

(An idea taken from the White-Hinrichs seminar.) Each session will have a discussion facilitator. The facilitator should read over the posted questions and choose a subset for discussion. In class, the facilitator should start the session with a fifteen minute summary of the day's readings, including the highlights and lowlights. Following the opening summary, the facilitator is responsible for managing the discussion, and ensuring that as many viewpoints are heard as possible. Students will be required to facilitate at least one session, and two if the number of participants allows. Auditors are expected to facilitate one session.

                        Term project (50%)

As noted above, students (other than auditors) will be required to carry out a term project on complexity and explanation or a related topic integrating their own research. A one-page sketch of the proposed research will be required by the end of the fifth week, followed by a two-page extended abstract in the eighth week, a presentation during finals week, and a final report by the day the final exam would be held (if we were having one).

Topics

The topics and (likely) readings we expect to cover are listed below. This list may be refined as the course progresses. The actual readings will be a subset of those listed, as I work through the list and try to figure out which pieces are most representative and useful. The actual schedule will be a version of the ordering provided here.

 

All of the readings except Goldberg 2005 are available in pdf format on the course page in Carmen.

 

Topic: Mainstream generative grammar and Simpler Syntax

It will be useful to have an overview on contemporary syntactic theory, in order to see what pieces might and might not contribute to accounting for complexity and explanation.

Topic: Universals

There is some very interesting work that tries to explain typological universals in terms of processing complexity. Reading this work will help us see the relationship between complexity and explanation, and will provide a candidate measure of complexity that we can carry forward with us as we read further.

Topic: Processing

Much of the work on complexity presupposes that complexity is tied to (real-time) processing. Gibson does a particularly good job of supporting this view of complexity on experimental grounds, and showing how it can explain judgments of relative acceptability made by native speakers.

Topic: Complexity and islands

Extending the idea that complexity explains unacceptability, some have taken the view that some or all of the so-called ‘extraction islands’ do not fall under grammaticality (contrary to mainstream syntactic theory) but are the consequence of complexity, which yields judgments of unacceptability. Kluender has done some interesting imaging work to support this view. Others, in particular Keller and Featherstone, have provided evidence that complexity is a constant across languages, while acceptability (and the threshold as to when something is unacceptable), varies across languages.

Topic: Constructions in grammar

Returning now to grammatical theory, in order to get the story of complexity right it is necessary to work out what it is that we are talking about. If the grammatical description doesn’t break things down right, it is going to be hard to account for complexity and thereby explain things. We’ll look at some work that argues that constructions are part of the native speaker’s knowledge of language, and therefore should be in the grammatical description. If this is right, then it will be necessary to account for how to measure the contribution of constructions to complexity.
