Neben der Frequenz eines cues ist es dessen Zuverlässigkeit, die Kindern hilft, die an sie gerichtete Sprache zu segmentieren, Worteinheiten zu erkennen sowie diese syntaktisch zu kategorisieren. Im Deutschen weist die Subsilbe „Langvokal+Konsonant+/t/“ (z.B. in fehlt, wohnt) zuverlässig auf eine -t-flektierte Verbform hin. Die in kindgerichteter Sprache höher frequente Subsilbe „Kurzvokal+Konsonant+/t/“ (z.B. in Feld, Hemd, fällt, rund) gibt hingegen keinen derartig eindeutigen Hinweis. Es wurde der Frage nachgegangen, inwiefern diese unterschiedlichen Zuverlässigkeiten und Frequenzen der Subsilben auf die Nomen-, Verb- und Verbflexionsverarbeitung einwirken. Drei Altersgruppen wurden untersucht: achtzehn Monate alte Kinder, drei- bis fünfjährige sprachunauffällige und -auffällige Kinder sowie erwachsene Sprecher. Einflüsse der unterschiedlichen Zuverlässigkeiten und Frequenzen der ausgewählten Subsilben konnten für alle Probandengruppen gefunden werden. Die Subsilbe stellt damit eine linguistische Größe dar, die in der frühen Sprachwahrnehmung als cue dienen sowie die Sprachverarbeitung Erwachsener lenken kann und auch für die Sprachdiagnostik und -therapie sprachauffälliger Kinder berücksichtigt werden sollte.
Vorwort
(2012)
Given the contemporary trend to modular NLP architectures and multiple annotation frameworks, the existence of concurrent tokenizations of the same text represents a pervasive problem in everyday's NLP practice and poses a non-trivial theoretical problem to the integration of linguistic annotations and their interpretability in general. This paper describes a solution for integrating different tokenizations using a standoff XML format, and discusses the consequences from a corpus-linguistic perspective.
Annotating linguistic data has become a major field of interest, both for supplying the necessary data for machine learning approaches to NLP applications, and as a research issue in its own right. This comprises issues of technical formats, tools, and methodologies of annotation. We provide a brief overview of these notions and then introduce the papers assembled in this special issue.
The German sibilant /integral/ is produced with a constriction in the postalveolar region and often with protruded lips. By covarying horizontal lip and tongue position speakers can keep a similar acoustic output even if the articulation varies. This study investigates whether during two weeks of adaptation to an artificial palate speakers covary these two articulatory parameters, whether tactile landmarks have an influence on the covariation and to what extent speakers can foresee the acoustic result of the covariation without auditory feedback. Six German speakers were recorded with EMA. Four of them showed a covariation of lip and tongue, which is consistent with the motor equivalence hypothesis. The acoustic output, however, does not stay entirely constant but varies with the tongue position. The role of tactile landmarks is negligible. To a certain extent, speakers are able to adapt even without auditory feedback.
Brain potentials for derivational morphology an ERP study of deadjectival nominalizations in Spanish
(2012)
This study investigates brain potentials to derived word forms in Spanish. Two experiments were performed on derived nominals that differ in terms of their productivity and semantic properties but are otherwise similar, an acceptability judgment task and a reading experiment using event-related brain potentials (ERPs) in which correctly and incorrectly formed derived words were presented in sentence contexts. The first experiment indicated productivity differences between the different nominalization processes in Spanish. The second experiment yielded a pattern of ERP responses that differed from both the familiar lexical-semantic and grammatical ERP effects. Violations of derivational morphology elicited an increased N400 component plus a late positivity (P600), unlike gender-agreement violations, which produced the biphasic LAN/P600 ERP pattern known from previous studies of morpho-syntactic violations. We conclude that the recognition of derived word forms engages both word-level (lexical-semantic) and decompositional (morpheme-based) processes.
First language (L1) phonological categories strongly influence late learners' perception and production of second language (L2) categories. For learners who start learning an L2 early in life ("early learners"), this L1 influence appears to be substantially reduced or at least more variable. In this paper, we examine the age at which L1 vowel categories influence the acquisition of L2 vowels. We tested a child population with a very narrow range of age of first exposure, controlling for the use of L1 vs. L2, and various naturally produced contrasts that are not allophonic in the L1 of the children. An oddity discrimination task provided evidence that children who are native speakers of Turkish and began learning German as an L2 in kindergarten categorized difficult German contrasts differently from age-matched native speakers. Their vowel productions of these same contrasts (un-cued object naming) were mostly target-like.
This article investigates the nature of preposition copying and preposition pruning structures in present-day English. We begin by illustrating the two phenomena and consider how they might be accounted for in syntactic terms, and go on to explore the possibility that preposition copying and pruning arise for processing reasons. We then report on two acceptability judgement experiments examining the extent to which native speakers of English are sensitive to these types of 'error' in language comprehension. Our results indicate that preposition copying creates redundancy rather than ungrammaticality, whereas preposition pruning creates processing problems for comprehenders that may render it unacceptable in timed (but not necessarily in untimed) judgement tasks. Our findings furthermore illustrate the usefulness of combining corpus studies and experimentally elicited data for gaining a clearer picture of usage and acceptability, and the potential benefits of examining syntactic phenomena from both a theoretical and a processing perspective.
