Non-human primate vocalizations and the evolution of speech and language
3:30 p.m., Herter 227
[+]more
Non-human primate calls are often treated as consisting of a restricted repertoire of innate and structurally fixed vocalizations (Tomasello 2008). This has led some researchers to consider that gestures such as pointing and pantomiming play a more important role in primate communication than vocalizations do. However, recent research on vocal communication by some monkey species has shown that their calls exhibit features that have thought to be absent from all non-human primate vocalizations, which evolved in environments where specifically vocal communication would have played a vital role in the species’ survival.
Vocalizations of apes and monkeys differ in major ways from human speech. There are no vowels, no consonants, and no obvious prosody. However, both apes and monkeys have an extremely variable voice source. This suggests that more information might be conveyed through the source rather than through the filter. The hypothesis is that a variable source evolved towards a more constant and controlled source. This is particularly obvious when the fundamental frequency (f0) is examined, because most apes’ and monkeys’ f0 are unstable and difficult to measure. One important feature of prosody in human speech, not observed in non-human primate vocalizations, is modulating f0 independent of intensity (Ohala 1970, Demolin 2007). The evolution to a more stable and controlled f0 is therefore a key element in the evolution of speech and language, which would have provided more our evolved primate ancestors with control over intonation and the syntactic, semantic and pragmatic information that intonation conveys. This probably happened through the co-evolution of the vocal tract’s anatomy and of the brain.
Recent findings in the study of some monkey calls reveal characteristics that put other important structural aspects of primate communication in a Darwinian perspective, i.e. as involving descent with modification. Ouattara et al. (2010) show that Campbell’s monkeys have overcome some of the constraints of limited vocal control by recombining parts of vocalizations to produce new ones with distinct uses. A part of the vocal repertoire of Muriqui monkeys (Mendes 1995, Demolin et al. 2010) relies on a form of grammar to recombine a limited set of elements to form strings. This grammar is more elaborated than a simple finite state grammar. Moreover Muriqui utterances exhibit a prosodic structure in which amplitude, duration and rhythm are all manipulated. The capacity to recombine signal elements may have evolved first in forest-dwelling primates like the Campbell and Muriqui monkeys because poor visibility in this habitat put evolutionary pressure their vocal skills.
These finding suggest that there is much more continuity between humans and their non-speaking cousins than it has been previously thought. Language and the set of mental processes which underlies it is after all the product of evolutionary forces.

Pronouns in Sign Language
3:30 p.m., Machmer E-37
[+]moreWe suggest that due to the difference in modality, sign language can bring fresh insights to the semantics of pronouns. Focusing on ASL (and in some cases LSF), we start by (re-)establishing that sign language pronouns ('indexes') share some non-trivial formal properties with spoken language pronouns, and in particular that they give rise to interesting binding-theoretic effects (e.g. Strong and Weak Crossover effects). We then show that the distinct morphology of sign language is helpful in two domains. First, it was argued in Anand
2006 that 'shifted' first person pronouns in Zazaki should be analyzed via a context-shifting operator that is optionally prefixed to embedded clauses. We suggest that some uses of 'Role Shift' in ASL might be the morphological realization of Anand's operator, and we show that Anand's specific predictions are borne out in that language.
Second, there has been a lively debate about the possibility of having binding without c-command ('donkey anaphora'); we argue that data from American and French Sign Language provide morphological evidence in favor of the conclusions of dynamic semantics, and against some versions of E-type approaches.

De-Maxim-izing Quality
3:30 p.m., Machmer E-37
[+]moreIn this talk I will be concerned with general principles governing the relationship between what speakers say and what they are taken by their interlocutors to believe. My starting point is Grice's maxim of Quality (“Try to make your contribution one that is true”), which is standardly assumed to underlie implications about the speaker's propositional attitude toward the content of her contribution. If the speaker is meeting the demands of Quality, as interlocutors normally presume, then addressees can infer that the speaker believes what she is saying and (believes she) has sufficient evidence for it.
Although this standard picture has much to recommend it, it has long been recognized that Quality operates somewhat differently than the other maxims, with Grice himself being the first to remark on its exceptional nature. I will focus on the differences in the first part of the talk, summarizing and adding observations about its special character. The conclusion is that Quality is not just an unusual sort of maxim, it is a different sort of beast altogether. In the second part of the talk I translate the observations into a set of requirements for the implementation of Quality, and sketch one such implementation.

Word-based sounds patterns and consonant epenthesis: The origins of non-etymological velar nasals in Palauan
3:30 p.m., Machmer E-37
[+]moreAn understudied aspect of the world’s phonologies are word-based sound patterns in which a particular segment or segment type is strongly preferred at the edge of a word. Several examples of these patterns are illustrated, with a more in depth study of the synchronic distribution and diachronic origins of word-edge velar nasals in Palauan. A restrictive theory of phonetically-based consonant-epenthesis, like that proposed within Evolutionary Phonology, narrows the hypothesis space for diachronic developments, leading to a reconsideration of morphological origins.

Generalized Contiguity and the Prosody of Adjacency
3:30 p.m., Machmer E-37
[+]moreIn Richards 2010, I proposed a universal condition on the prosody of wh-questions, the purpose of which was to predict whether a given language would move its wh-phrases or leave them in situ. In this talk I will modify that proposal slightly, and then generalize it to condition relations between Probes and Goals more generally. We will see that the condition derives a number of effects classically assigned to conditions on head-movement. Friday, September 17, 2010
Marginal contrasts in Tongan loanword phonology
3:30 p.m., Machmer E-37
[+]morejoint work with Kathleen O'Flynn and Kaeli Ward
Stress is normally predictable in Tongan (Polynesian). However, data from consultation with three Tongan speakers shows that secondary stress in loans is influenced by whether a vowel in the loan correspond to a stressed vowel in the English source word, to an unstressed vowel, or to nothing (i.e., is etymologically epenthetic).
Tongan phonotactics normally forbid consonant clusters in careful speech, but allow some to result through variable vowel deletion. In our corpus of loans, vowel deletion is again influenced by whether the vowel is etymologically epenthetic.
This means that Tongan speakers must be able to perceive certain contrasts that fall outside of L1, and encode them in representations of loanwords. We discuss this finding in light of recent research on L2 perception and loan adaptation (e.g., Peperkamp 2004).
We also consider the mechanics of how these loan-only contrasts could be encoded in lexical entries. Treating certain loans as pseudocompounds is attractive (see Schütz 2001), but runs into problems with long vowels and does not address vowel deletion. It seems instead that some lexical entries of loans must include information that is not normally contrastive in the language. In addition, the information must be encoded at the level of the segment rather than at the level of the entire morpheme, narrowing down the theories of lexical exceptionality that could work for this case.
