However, the extent to which knowledge of phonemic units may interact with spoken language organization in (transparent) alphabetical languages has hardly been investigated. The present study examined whether phonemic awareness correlates with coarticulation degree, commonly used as a metric for estimating the size of children's production units. A speech production task was designed to test for developmental differences in intra-syllabic coarticulation degree in 41 German children from 4 to 7 years of age. The technique of ultrasound imaging allowed for comparing the articulatory foundations of children's coarticulatory patterns. Four behavioral tasks assessing various levels of phonological awareness from large to small units and expressive vocabulary were also administered. Generalized additive modeling revealed strong interactions between children's vocabulary and phonological awareness with coarticulatory patterns. Greater knowledge of sub-lexical units was associated with lower intra-syllabic coarticulation degree and greater differentiation of articulatory gestures for individual segments. This interaction was mostly nonlinear: an increase in children's phonological proficiency was not systematically associated with an equivalent change in coarticulation degree. Similar findings were drawn between vocabulary and coarticulatory patterns. Overall, results suggest that the process of developing spoken language fluency involves dynamical interactions between cognitive and speech motor domains. Arguments for an integrated-interactive approach to skill development are discussed.}, language = {en} } @misc{FestmanClahsen2016, author = {Festman, Julia and Clahsen, Harald}, title = {How Germans prepare for the English past tense}, series = {Postprints der Universit{\"a}t Potsdam : Humanwissenschaftliche Reihe}, journal = {Postprints der Universit{\"a}t Potsdam : Humanwissenschaftliche Reihe}, number = {521}, doi = {10.25932/publishup-41445}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-414455}, pages = {487 -- 506}, year = {2016}, abstract = {Processes involved in late bilinguals' production of morphologically complex words were studied using an event-related brain potentials (ERP) paradigm in which EEGs were recorded during participants' silent productions of English past- and present-tense forms.

The essential variable in the models is syllable structure. When mapped to discrete coordination topologies, syllabic organization imposes systematic patterns of variability on the temporal dynamics of speech articulation. We simulated these dynamics under different syllabic parses and evaluated simulations against experimental data from Arabic and English, two languages claimed to parse similar strings of segments into different syllabic structures. Model simulations replicated several key experimental results, including the fallibility of past phonetic heuristics for syllable structure, and exposed the range of conditions under which such heuristics remain valid. More importantly, the modelling approach consistently diagnosed syllable structure proving resilient to multiple sources of variability in experimental data including measurement variability, speaker variability, and contextual variability. Prospects for extensions of our modelling paradigm to acoustic data are also discussed.}, language = {en} } @misc{FestmanClahsen2016, author = {Festman, Julia and Clahsen, Harald}, title = {How Germans prepare for the English past tense}, series = {Postprints der Universit{\"a}t Potsdam Humanwissenschaftliche Reihe}, journal = {Postprints der Universit{\"a}t Potsdam Humanwissenschaftliche Reihe}, number = {504}, issn = {1866-8364}, doi = {10.25932/publishup-41367}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-413678}, pages = {20}, year = {2016}, abstract = {Processes involved in late bilinguals' production of morphologically complex words were studied using an event-related brain potentials (ERP) paradigm in which EEGs were recorded during participants' silent productions of English past- and present-tense forms.
