Stress in Mehweb: A Lexically Filled Optimality Theory Approach
The volume presents several papers on Mehweb, a one-village language spoken in the central part of Daghestan, a republic of the Russian Federation.
Speech production, both overt and covert, down-regulates the activation of auditory cortex. This is thought to be due to forward prediction of the sensory consequences of speech, contributing to a feedback control mechanism for speech production. Critically, however, these regulatory effects should be specific to speech content to enable accurate speech monitoring. To determine the extent to which such forward prediction is content-specific, we recorded the brain's neuromagnetic responses to heard multisyllabic pseudowords during covert rehearsal in working memory, contrasted with a control task. The cortical auditory processing of target syllables was significantly suppressed during rehearsal compared with control, but only when they matched the rehearsed items. This critical specificity to speech content enables accurate speech monitoring by forward prediction, as proposed by current models of speech production. The one-to-one phonological motor-to-auditory mappings also appear to serve the maintenance of information in phonological working memory. Further findings of right-hemispheric suppression in the case of whole-item matches and left-hemispheric enhancement for last-syllable mismatches suggest that speech production is monitored by 2 auditory-motor circuits operating on different timescales: Finer grain in the left versus coarser grain in the right hemisphere. Taken together, our findings provide hemisphere-specific evidence of the interface between inner and heard speech.
The article is devoted to the problem of the structure of pragmatic constraints. The fact that gricean maxims are neither pure descriptive rules nor pure prescriptive ones is one of the puzzles of early pragmatic theories. I try to clarify the problem of ontological status of pragmatic constraints by means of game theory and optimality theory.
The Mehweb language is an isolated one-village language of the Dargwa group (Nakh-Daghestanian). Mehweb speakers moved outside the Dargwa-speaking area and now they are located near the Avar and Lak speakers. Many authors treated Mehweb specific features as archaic. In this paper I argue that some features of the Mehweb consonant system shows many innovations which could be partly explained by contacts with other languages and specific Mehweb internal processes.
especially impaired on regular past-tense forms like played, whether the task requires production, comprehension or even the judgement that "play" and "played" sound different. Within a dual-mechanism account of inflectional morphology, these deficits reflect disruption to the rule-based process that adds (or strips) the suffix -ed to regular verb stems; but the fact that the patients are also impaired at detecting the difference between word pairs like "tray" and "trade" (the latter being a phonological but not a morphological twin to "played") suggests an important role for phonological characteristics of the regular past tense. The present study examined MEG brain responses in healthy participants evoked by spoken regular past-tense forms and phonological twin words (plus twin pseudowords and a non-speech control) presented in a passive oddball paradigm. Deviant forms (played, trade, kwade/kwayed) relative to their standards (play, tray, kway) elicited a pronounced neuromagnetic response at approximately 130 ms after the onset of the affix; this response was maximal at sensors over temporal areas of both hemispheres but stronger on the left, especially for played and kwayed. Relative to the same standards, a different set of deviants ending in /t/--plate, trait and kwate--produced stronger difference responses especially over the right hemisphere. Results are discussed with regard to dual- and single-mechanism theories of past tense processing and the need to consider neurobiological evidence in attempts to understand inflectional morphology.
The book is devoted to the word order typology. The languages with free order are under discussion. It concerns verious phenomena that can trgger word order variation and have impact on the syntactic structure of a sentence such as infromation structure, differential argument marking, clitics position etc.
