Show moreSelf-perceived word-finding difficulties are common in aging individuals as well as in Alzheimer's Disease (AD). Language and speech deficits are difficult to objectify with neuropsychological assessments. We therefore aimed to investigate whether amyloid, an early AD pathological hallmark, is associated with speech-derived semantic complexity. We included 63 individuals with subjective cognitive decline (age 64 ± 8, MMSE 29 ± 1), with amyloid status (positron emission tomography [PET] scans n = 59, or Aβ1-42 cerebrospinal fluid [CSF] n = 4). Spontaneous speech was recorded using three open-ended tasks (description of cookie theft picture, abstract painting and a regular Sunday), transcribed verbatim and subsequently, linguistic parameters were extracted using T-scan computational software, including specific words (content words, frequent, concrete and abstract nouns, and fillers), lexical complexity (lemma frequency, Type-Token-Ratio) and syntactic complexity (Developmental Level scale). Nineteen individuals (30%) had high levels of amyloid burden, and there were no differences between groups on conventional neuropsychological tests. Using multinomial regression with lin- guistic parameters (in tertiles), we found that high amyloid burden is associated with fewer concrete nouns (ORmiddle (95%CI): 7.6 (1.4–41.2), ORlowest: 6.7 (1.2–37.1)) and content words (ORlowest: 6.3 (1.0–38.1). In addition, we found an interaction for education between high amyloid burden and more abstract nouns. In conclusion, high amyloid burden was modestly associated with fewer specific words, but not with syntactic complexity, lexical complexity or conventional neuropsychological tests, suggesting that subtle spontaneous speech deficits might occur in preclinical AD.

Show moreThe Central Chadic languages are a diverse and fascinating collection of languages, spoken in Nigeria, Cameroon and Chad. The phonologies of these languages have intrigued linguists since they were first studied, due to their minimal sets of phonemic vowels (sometimes only one), complex systems of vowel harmony, and extensive use of palatalized and labialized consonants. Analysis of these languages led to the proposal of phonemic units referred to as ‘prosodies’, which act on both vowels and consonants, allowing Central Chadic phonologies to be described in a neat and succinct way. This study looks at the diverse phonological systems found within Central Chadic, and reconstructs the phonological system of their ancestor language. This system is itself simple and succinct, and includes one phonemic prosody and just three phonemic vowels. The study describes the phonological processes that led from this system to the many phonological systems that are in use today, shedding light both on the history of the languages, and on issues in the analysis of these languages.

Show moreThe Awjila language is a small Berber language spoken in the Libyan oasis of Awjila. It has several features that make the language different from other Berber languages, such as a phonemic accent, schwa in open syllables and the retention of the Proto-Berber *_ as v. This thesis consists of three parts: the grammar, the texts and the lexicon. The grammar is the main analytical part of this thesis, but could not exist without the in-depth study of the available Awjila texts and the lexicon. Due to the political situation in Libya, it was not possible to conduct fieldwork on the language. This thesis is therefore based on the published sources on the language. The texts and word list by Umberto Paradisi are the most important of these sources. The grammar contains a lengthy discussion on the interpretation and analysis of the transcription and phonology. This part give us many new insights into the interpretation of many factors of the language. Besides the phonology, the grammar also discusses the morphology of the noun and verb, and the syntax of the language. In the appendix all published Awjila texts have been included, provided with a phonemic transcription and a word-by-word analysis. This analysis is essential for the understanding of the language, and it is referenced extensively in the grammar. The lexicon contains all lexical material available to us on the Awjila language, with a new phonemic analysis of the transcriptions, and a full concordance of all the attestations of the words in its different grammatical forms in the available sources. The lexicon also contains some etymological notes, comparing Awjila to the other Berber languages which will aid future research into the linguistic history of Awjila and other Berber languages.
