Ailis Cournane in the journal Language Acquisition

Congratulations to PhD student Ailis Cournane for her just published article in the journal Language Acquisition!  The title of the article is "In Search of L1 Evidence for Diachronic Reanalysis: Mapping Modal Verbs".

Abstract

The lexical mapping of abstract functional words like modal verbs is an open problem in acquisition (e.g., Gleitman et al. 2005). In diachronic linguistics it has been proposed that learner mapping errors are responsible for innovations in the historical record (see Kiparsky 1974; Roberts & Roussou 2003, among others). This suggests that child error patterns should be consistent with historical changes. I studied the acquisition of modal lexemes by flavor (e.g., ability, epistemic) in order to assess the validity of this proposal in relation to the mapping problem. A preference task and a sentence-repair task were designed to address the question: Do children make structural mapping errors that, if left unchecked, are compatible with the innovations we see in the historical record (e.g., deontic > epistemic)? This study provides experimental data on the acquisition of modal lexemes by flavor and some long-awaited preliminary support for the hypothesis that child learners drive historical change.

ABSTRACT:

Language for communication: Language as rational inference
Ted Gibson, MIT

Perhaps the most obvious hypothesis for the function of human language is for use in communication. Chomsky has famously argued that this is a flawed hypothesis, because of the existence of such phenomena as ambiguity. Furthermore, he argues that the kinds of things that people tend to say are not short and simple, as would be predicted by communication theory. Contrary to Chomsky, my group applies information theory and communication theory from Shannon (1948) in order to attempt to explain the typical usage of language in comprehension and production, together with the structure of languages themselves. First, we show that ambiguity out of context is not only not a problem for an information-theoretic approach to language, it is a feature. Second, we show that language comprehension appears to function as a noisy channel process, in line with communication theory. Given si, the intended sentence, and sp, the perceived sentence we propose that people maximize P(s i | sp ), which is equivalent to maximizing the product of the prior P(si) and the likely noise processes P(si → sp ). We show that several predictions of this way of thinking of language are true: (1) the more noise that is needed to edit from one alternative to another leads to lower likelihood that the alternative will be considered; (2) in the noise process, deletions are more likely than insertions; (3) increasing the noise increases the reliance on the prior (semantics); and (4) increasing the likelihood of implausible events decreases the reliance on the prior. Third, we show that this way of thinking about language leads to a simple re-thinking of the P600 from the ERP literature. The P600 wave was originally proposed to be due to people's sensitivity to syntactic violations, but there have been many instances of problematic data in the literature for this interpretation. We show that the P600 can best be interpreted as sensitivity to an edit in the signal, in order to make it more easily interpretable. Finally, we discuss how thinking of language as communication can explain aspects of the origin of word order. Some recent evidence suggests that subject-object-verb (SOV) may be the default word order for human language. For example, SOV is the preferred word order in a task where participants gesture event meanings (Goldin-Meadow et al. 2008). Critically, SOV gesture production occurs not only for speakers of SOV languages, but also for speakers of SVO languages, such as English, Chinese, Spanish (Goldin-Meadow et al. 2008) and Italian (Langus & Nespor, 2010). The gesture-production task therefore plausibly reflects default word order independent of native language. However, this leaves open the question of why there are so many SVO languages (41.2% of languages; Dryer, 2005). We propose that the high percentage of SVO languages cross-linguistically is due to communication pressures over a noisy channel. We provide several gesture experiments consistent with this hypothesis, and we speculate how a noisy channel approach might explain several typical word order patterns that occur in the world's languages.

'Syntax Squib Section' (S3) Meeting (Jan 31)

Phonetics-Phonology Group Meeting (Jan 31)

Phon group meets today (January 31st) from 11am-1:30pm in SS 560A. Peter Jurgec will be giving a talk, titled "Schrödinger's Features". 

Abstract:

This talk analyzes incomplete neutralization as a phonological pattern. The main idea is that incomplete neutralization arises because it can satisfy both faithfulness AND markedness. (In contrast, complete neutralization satisfies a markedness constraint, but violates a faithfulness constraint.) The solution is representational. I propose that feature values can be ambiguous. In particular, a binary feature [F] can be simultaneously both [+F] and [-F]. The talk explores the consequences of allowing such representations. Two cases of incomplete neutralization are analyzed: final devoicing in German (with binary features) and vowel lengthening in Japanese (with privative features).

LVC Group Meeting (Jan 31)

The LVC Group meets  9:30 - 11:00 today (Jan 31) in SS 560A. Shayna Gardiner will present on sociolinguistic variation in ancient Egyptian texts.

Field Methods Discussion Group (Jan 24)

Taking place today is the first meeting of a new discussion group dedicated to the discussion of linguistic fieldwork and field methodology. The hope is to be able to talk about both practical and theoretical questions related to linguistics in the field among people with different levels of experience, and from different subfields.

The meeting will take place at 2pm in SS560A, on alternating Fridays in accordance with the schedule Keren has circulated. This week will be a planning meeting: topics and issues will be set out for the following weeks.

Syntax-Semantics Project Meeting (Jan 24)

Syntax-semantics project will be taking place this Friday, January 24th, in SS560A from 12-2 pm. Ivona Kucerova and Susana Bejar will present "Presupposition and phi-features in the nominal domain: Evidence from dependent plurals"

Abstract:
Based on morpho-syntactic variation in the domain of dependent plurals in English, we argue that Agree and valuation do not need to happen simultaneously (Pesetsky and Torrego 2007), however, transfer strictly requires chains headed by the corresponding phase head to be valued. The consequence of the proposed model is that if there are morpho-semantic mismatches in a nominal domain (for instance in the number valuation), the higher phase must be grammatically congruent with D, while the lower phase may be mismatched.

NB: Future meetings of the group will begin at 11:30 am and end at 1 pm.

Psycholinguistics Group Meeting (Jan 24)

Danielle Moed (MA student, LIN) will present in preparation for her forum research. The presentation is entitled "Structure or Concept: What are people more willing to compromise in language production?". The group meets in Sid Smith 560A and will start at 10:15am.

NB: Future meetings of this group will start at 9:30 am (sharp) and end at 11:00 am.

Phil Howson was in San Francisco last month for the 166th Meeting of the Acoustical Society of America, where he gave a poster presentation entitled 'Electropalatography examination of groove width in Russian.'

Phonology Group Meeting (Jan 17)

The Phonetics-Phonology Group met on January 17th. There was a guest talk by Wendell Kimper from the University of Manchester. Title and abstract are below:

Trigger Competition and Locality Asymmetries in Harmony

This talk presents an analysis of locality asymmetries in vowel harmony. In languages with multiple segments which fail to undergo harmony, these segments may differ with respect to their ability to be treated as transparent. In Hungarian, for example, [i] is consistently transparent, but [e] exhibits variable behaviour and can be either transparent or opaque. What is responsible for these segments' diverging behaviour? I argue that locality asymmetries are best understood as an effect that emerges from the interaction between two general preferences in harmony --- the status of certain segments as privileged triggers, and the marked status of non-local interactions. I present an analysis in Serial Harmonic Grammar; harmony is driven by a positively-defined scalar constraint, with decreased rewards for non-local harmony and increased rewards for harmony originating from a preferred trigger.

LVC Group Meeting (Jan 17)

The LVC Group met on Friday Jan 17th. Yoonjung Kang gave a talk about variation in vowel length in Korean, looking at the vowel length contrast merger in Seoul Korean. The talk examined the effects of phonological conditions and frequency of use on the lexical diffusion of vowel length merge.

Special phonology group talk by Nicholas Rolle

There will be a special meeting of the phonology group at 5pm today in the lounge, with a guest talk by alumnus Nicholas Rolle. Title and abstract follow.

Title: Nasal vowel systems in West Africa: Typological, areal, and perceptual perspectives
 
Abstract:

Contrastive nasal vowels are a common feature of West African phonological systems, and have contributed significantly to previous descriptively and theoretically oriented Africanist work - e.g. Hyman (1972), Williamson (1973), Maddieson (1984, 2007), Clements (2000), Clements & Rialland (2006), and Miehe (2013). There remain, however, a number of issues which are insufficiently addressed: (1) in which precise geographic areas and genetic groups do we find nasal vowels in West Africa, (2) what are the profiles of these nasal vowel inventories and how are they geographically and genetically distributed, and (3) how can we situate these patterns within larger typological-areal and phonetic-phonological literature?
 
To this end, we have created a typological database of 246 languages/language clusters in West Africa, covering all major families. This survey supports previous work which identifies an expansive areal zone stretching roughly south of the Sahel from Guinea to Nigeria, within which contrastive nasal vowels are nearly categorical. We refer to this area as the West African Nasal Vowel Zone. A novel component of our survey is that we also coded for vowel inventory type, focusing on identifying gaps in the nasal vowel inventory. We found that while the overwhelming majority of West African languages contrast oral /e o/ vs. /ɛ ɔ/ (epsilon and open o), a large continuum of languages stretching from Western Nigeria into Cote D'Ivoire lack nasal /ẽ õ/, constituting the core of the Nasal Vowel Zone. In contrast, languages which show the presence of contrastive /ẽ õ/ appear at the fringes of the West African Nasal Vowel Zone. We show that both of these patterns are subject to areal effects which cut across genetic group.
 
We conclude our discussion by situating these patterns more broadly, noting two major findings. The first is that a robust and areal constraint against /ẽ õ/ as found in West Africa is not mirrored in other nasal vowel zones, such as South America and Mesoamerica. In the second, we note that a gap of /ẽ õ/ can be understood as phonetically natural due to oral-nasal acoustic coupling effects on F1 perception (Ohala 1975, Wright 1986, Beddor et al. 1986, Beddor 1993, Maeda 1993), referred to as the Nasal Height-Centralization Effect. We present, however, a series of arguments against a "phonetic determinism” account, and understand these patterns as the result of an interplay of acoustic and areal pressures.
