NAP-dag 2014: abstracts Sterre Leufkens: Degrees of transparency – why some languages maintain their historical junk A transparent language is a language in which each linguistic form corresponds consistently to one pragmatic or semantic element. I performed a typological comparison, which led to a ranking of 22 languages in terms of their degree of deviation from full transparency. Relatively non-transparent languages such as Dutch and Egyptian Arabic maintain certain elements that convey no meaning at all, but have morphosyntactic or phonological relevance only. Why do such features remain in these languages? Konrad Rybka: The language of vanishing ecotopes In this talk, I use first-hand landscape data from Lokono, a critically endangered Arawakan language spoken in Suriname, Guyana and French Guiana to discuss the linguistic and conceptual structure of ecotopes. The Lokono ecotope terms are derived from a noun encoding a botanical resource with either the suffixe –wkaro or –wkili, for instance, mokorowkaro ‘an area of the mokoro reed (Ischnosiphon arouma)’ or awarhawkili ‘an area of the awarha palm (Astrocaryum vulgare)’. The speakers acknowledge a meaning difference between the two derivational forms, but are unable to formulate it. I use hierarchical clustering and multidimensional scaling to shed light on the semantics of the two suffixes. At the same time, I expose the wealth of culturally specific knowledge associated with the ecotopes. Jasmin Pfeifer: Congenital amusia and pitch memory Congenital Amusia is a neuro-developmental disorder that has a negative influence on pitch perception in language and music. For my PhD project I am conducting various perception studies with Dutch and German amusics. This talk will give a brief introduction to congenital amusia: its symptoms, surmised underlying deficits, how it is diagnosed, and current research issues. I will give a short overview of my experiments so far and then focus on a study about pitch memory, in which amusics’ pitch memory was manipulated with transcranial alternating current stimulation (tACS). Joey Weidema: Through the looking glass: an investigation into speech-specific and musicspecific mechanisms of pitch processing One aspect of pitch perception, contour processing, has been shown to display a significant overlap in terms of brain dynamics when attending to linguistic and musical stimuli. There is no consensus, however, on whether pitch processing in language and music rely on shared computational resources or operate in a modular, domain-specific manner. Auditory illusions that blur the boundaries between language and music provide interesting grounds to test the nature of pitch in both domains. In this talk I will discuss some of these illusions and propose an experimental paradigm that can be used to investigate claims regarding modular vs. shared pitch perception in language and music. Mirjam de Jonge: Neural reflections of privative phonological features The use of privative features in phonological representations, as opposed to binary features, has consequences for the predicted levels of perceived contrast between speech sounds depending on stimulus order. The current study was designed to critically test the predictions that arise from binary features and from the different sets of privative features employed in the Featurally Underspecified Lexicon model and in Element Theory. We measured the Mismatch Negativity, a neural measure of auditory contrast, of French participants listening to French vowels in an oddball paradigm. The results are in line with the predictions based on the Featurally Underspecified Lexicon model. Klaas Seinhorst: Learning preferences in plosive segment inventories The sound systems of the world’s languages show clear patterns: certain sets of feature combinations are preferred over others. In the literature, these tendencies have been linked to ease of learning, but so far this hypothesis lacked empirical support. In this talk I present results from a pilot study in which participants learned data sets that differed in feature economy and logical complexity. The outcomes suggest three things: (i) certain sets are significantly more difficult to learn than others; (ii) logical complexity is a better predictor of learning success than feature economy; (iii) iteration of the attested learning preferences yields a system that reflects typological tendencies. Patrick Schetters: Accuracy in the written production of proficient learners of Dutch as a second language with L1 German Due to the close relatedness of both languages it is relatively easy for German L1 speakers to obtain an advanced knowledge of Dutch. However, most of the learners still struggle when it comes to bringing their command of language to perfection. Based on a corpus of written essays from proficient German-speaking learners of Dutch as a foreign language a quantitative and qualitative analysis of accuracy at levels B2/C1 (according to the CEFR) will be made. At the same time the project tries to determine didactic measures and conducts relevant experiments in order to optimise accuracy in advanced levels of written foreign language production.
