Attributive participle constructions in German behave like adjectives in terms of inflection and position, but keep their verbal arguments. They can be extended by adjuncts or arguments and these extended attributive present participles mainly occur in written language (Weber, 1994). As the same content can also be expressed in a relative clause (RC), I compare both constructions in order to find out under which conditions a participle construction could lead to processing difficulties and how this relates to RC processing.
Based on previous assumptions for production (e.g. Weber, 1971; Fabricius-Hansen, 2016), three potential factors on the comprehension of prenominal modifiers and RCs are investigated: modifier length, the internal structure and multiple levels of embedding. The hypotheses for an effect on modifier length are mainly based on two processing accounts that make opposite predictions under specific circumstances: memory-based accounts such as the dependency locality theory (DLT) (e.g. Gibson, 2000) and expectation-based accounts such as surprisal (e.g. Levy, 2008). An increase in modifier length results in more intervening material between determiner and noun for the participle construction, contrary to RCs where these elements are adjacent. This separation of the DP could increase memory load. Therefore, longer participles would slow down processing of the noun, while there should be no difference for RCs. Two acceptability judgment experiments showed a tendency for longer participle phrases to receive lower ratings. The modifier length was further investigated in online processing. Contrary to the predicted locality effect, self-paced reading data reveals an anti-locality effect for participle phrases, with lower RTs on the noun when additional material was present inside the modifier. This experiment was followed up by an eye-tracking experiment which replicated the anti-locality effect, but at the participle instead at the noun.
The second factor that was investigated is the argument structure of the participle (or RC verb). My hypothesis is that more “prototypical” adjectives in terms of syntactic structure and semantics are more acceptable and easier to process. Attributive participles are considered hybrids between verbs and adjectives (e.g. Fuhrhop & Teuber, 2000; L¨ubbe & Rapp, 2011) due to their modifier internal verbal function, but adjectival position and agreement with the noun. This double role could lead to difficulties, in particular with a more complex verbal structure. Therefore, the prediction was that the presence of an accusative object inside a participle phrase would lead to lower acceptability ratings and higher reading times in online processing. In the first two acceptability experiments, this prediction was borne out. In addition, an SPR experiment was conducted which manipulated the presence of either an accusative object or adjunct for participles (of verbs that could be used intransitively and transitively) and the corresponding RCs. The experiment showed an effect of the presence of an accusative object on the participle, with higher reading times if an object was present, compared to an adjunct. No such difference was found for the RC verb, which indicates that only participles are processed more slowly when there is an accusative object. An alternative explanation for this finding is the inherent imperfective aspect of the present participle: a direct object could change the event structure in such a way that the aspect no longer matches.
The third factor I investigate is an effect of double embedding on the acceptability of participle phrases and RCs. While double embedded participles are rated lower than double embedded RCs, there is a smaller decrease from single to double embedding for participles than for RCs, contrary to the predictions calculated by the metric of the DLT.
Overall, the results provide evidence for experience-based processing, but they cannot be explained by either memory- or experience-based accounts alone. The effect concerning the presence of an accusative object suggest that properties of the participle distinguish the construction from RCs and affect its processing. The thesis suggests that the latter effect needs to be investigated further in future research. Furthermore, the findings have implications for the role of attributive present participles in German and for hypotheses about similar constructions in other languages.
This thesis reports three experiments on structural choices during grammatical encoding in monolingual adult speakers of German. Conceptual accessibility, one of the most central notions in language production research, as well as the phenomena of structural and perceptual priming are investigated.
In the first two experiments, a manipulation in terms of inherent conceptual accessibility which has shown universal influences on language production - the factor animacy - is combined with a manipulation making the non-canonical passive structure itself more accessible via structural priming.
Results show that, in addition to a preference for animate entities preceding inanimate entities, speakers can be structurally primed. Structural priming of passive structures led to significantly more passive responses compared to (intransitive) baseline structures.
This holds for monologue settings (Experiment 1) as well as dialogue settings (Experiment 2).
The structural priming effect was stronger in the dialogue setting compared to the monologue setting.
The third experiment combines contexts manipulating the derived conceptual accessibility of one of two entities to be described with a visual cueing manipulation increasing the perceptual accessibility of one of the referents.
Whereas a comprehensive literature review as well as the experimental work conducted within this thesis suggest that animacy and topicalization may exert universal influences on structural choices during language production, perceptual accessibility does not seem to have this potential.
In line with previous cross-linguistic work, perceptual priming in form of an implicit visual cueing manipulation did not show significant effects on speakers' structural choices in German.
These findings contrast with findings obtained for English, suggesting that language-specific characteristics in terms of word order flexibility may influence effcts on grammatical encoding during language production.
Increasing the derived accessibility of one of two referents, however, once again showed significant influences on speakers' structural choices with the topicalization of a patient referent leading to an enhanced production of passive responses.
This thesis investigates the acquisition pace and the typical developmental path in eL2 acquisition of selected phenomena of German morphosyntax and semantics and compared them to monolingual acquisition. In addition, the influence of ‘Age of Onset’ and of external factors on eL2 acquisition is examined.
To date, the most studies on eL2 acquisition focused on language production. Based on mostly longitudinal spontaneous speech data of only small number of children, they indicate that eL2 learners acquire sentence structure and subject-verb-agreement faster than monolingual children, whereas the acquisition of case marking causes them more difficulties. Moreover, similar developmental paths to those of monolingual children are claimed. Only several studies examined comprehension abilities in eL2 learners, however overwhelmingly in cross-sectional design. The findings from comprehension studies on telic and atelic verbs, and on wh-questions indicate that eL2 children acquire their target-like interpretation faster than monolingual children. The same acquisition stages towards target-like interpretation like in monolingual acquisition are assumed as well. Taking together, to date, no study exists, that examines comprehension and production abilities in a large group of eL2 learners of German in a longitudinal design.
This thesis extends the previous results by investigating pace of acquisition, impact of factors, and individual developmental paths in a longitudinal design with large groups of participants. Language data of 29 eL2 learners of German (age at T1: 3;7 years, LoE: 10 months) and 45 monolingual German-speaking children (age at T1: 3;7) are examined. The eL2 learners were tested in six test rounds (age at T6: 6;9 years). The monolingual children were tested in five test rounds (are at T5: 5;7). The standardized test LiSe-DaZ (Schulz & Tracy, 2011) was employed to examine children’s language skills.
eL2 learners show a significantly greater rate of change, thus faster acquisition pace, than monolingual children in the following scales: comprehension of telicity, comprehension of wh-questions, production of prepositions, and production of conjunctions. These phenomena are acquired early in monolingual children. No differences regarding acquisition pace between eL2 children and monolingual children are found for comprehension of negation, production of case marking, and production of focus particles. These phenomena are acquired late in monolingual development and involve semantic and pragmatic knowledge. The findings of faster acquisition pace of several phenomena are in line with several studies that reported that eL2 children develop faster than monolingual children.
Independent on whether a phenomenon is acquired early or late, no effects of external factors on eL2 children’s performance are found. These findings indicate that acquisition of core, rule-based phenomena is not sensitive to external factors if the first exposure to L2 takes place around the age of three.
Moreover, eL2 children show the same developmental stages and error types in comprehension of telicity, comprehension of negation, production of matrix and subordinate clauses. This is also independent on how fast they acquire a structure under consideration. Thus, these findings provide a further support for similar developmental paths of eL2 and monolingual children towards target-like comprehension and production.
Towards a German grammar programme for post-leaving certificate students at Dublin City University
(1999)
With the introduction of the communicative method of language learning, overall standards of grammatical competence and performance among Irish second level students would appear to have been significantly reduced. As a consequence, learners who continue to study a given language at third level apparently no longer possess the knowledge which, under the grammar-translation methodology, further education institutions were able to build upon. This thesis examines the basis for the above perceptions, investigates the role of formal grammar instruction in the second language acquisition process and reports on a programme which was developed at Dublin City University (DCU) in order to ease, for Irish university students of German, the transition from a primarily memory-based approach to language acquisition to the analytical approach which is still being considered crucial to a university student's linguistic education. While the research was undertaken in response to locally existing difficulties, it may also be considered as a case study of more general interest, and as such serve as an exemplar to German departments in other universities as well as to other foreign language departments both within DCU or outside. The aim of the programme under investigation was to ease the transition on a socio-affective, cognitive and metacognitive level without lowering overall proficiency expectations and standards. Primary research was conducted among secondary school teachers, post-Leaving Certificate students on entry into DCU and among third level lecturers. The purpose of this research was to identify and define the programme’s content and progression. To this effect, the German junior and senior cycle syllabi at second level were also taken into consideration. The subsequent German grammar programme was implemented at DCU in the academic year 1996/7. While the programme would appear to have been judged favourably regarding some affective and cognitive-motivational aspects, results show mixed success rates for the other two factors under investigation, cognitive-analytical and metacognitive skills. Thus, some degree courses and some language combinations clearly benefited more from the programme than others. One of the conclusions drawn from this research suggests that unless certain changes are introduced prior to students’ entry into third level, university graduates are likely to remain well below the standards of accuracy and overall proficiency which were previously achieved.
This study identifies the language learning strategies associated with the achievement of higher levels o f oral proficiency in German for one hundred Irish third level students. It is one of the first studies of this kind to be conducted in Ireland and one of the very few, if any, conducted on third level learners of German. Furthermore, as well as identifying the strategies associated with higher levels of proficiency, the study also investigates how these strategies are used by learners displaying higher and lower levels of proficiency. It then explores the question of how the strategies associated with higher levels of proficiency contribute to the process of proficiency development, and how students perceive them as contributing to this process. Finally, the relationships between learner specific characteristics, strategic behaviour and proficiency levels are assessed. The experimental design combines a quantitative survey with in-depth interviews. The results indicate that orally more proficient students use more strategies more frequently. In particular, they use more cognitive, metacognitive and social strategies. Furthermore, they have a repertoire of approximately ten key strategies which they employ in a structured, purposeful manner and apply to a range of language learning situations. They are convinced that these strategies contribute to the development of proficiency, a view which is borne out by the quantitative findings. Finally, higher levels of motivation and more positive perceptions of personal proficiency levels are strongly associated with higher levels of both strategic behaviour and oral proficiency. These findings have significant theoretical and practical implications. Firstly, they demonstrate the importance of expanding the research framework in studies of this kind beyond the mere identification of the strategies associated with higher proficiency levels. Instead, as in this study, future research should incorporate questions relating to the process of strategy implementation by more and less successful learners and to relationships between the use of particular strategies and the process of foreign language acquisition. Secondly, the findings contribute to our understanding of the strategic behaviour of the orally more proficient student, and in particular the orally more proficient learner of German in an Irish third level context. This understanding relates primarily to the strategies these learners use, the way in which they use them and their attitudes towards their use. Such an understanding forms the basis of successful strategies based instruction in the language classroom.
Manual development of deep linguistic resources is time-consuming and costly and therefore often described as a bottleneck for traditional rule-based NLP. In my PhD thesis I present a treebank-based method for the automatic acquisition of LFG resources for German. The method automatically creates deep and rich linguistic presentations from labelled data (treebanks) and can be applied to large data sets. My research is based on and substantially extends previous work on automatically acquiring wide-coverage, deep, constraint-based grammatical resources from the English Penn-II treebank (Cahill et al.,2002; Burke et al., 2004; Cahill, 2004). Best results for English show a dependency f-score of 82.73% (Cahill et al., 2008) against the PARC 700 dependency bank, outperforming the best hand-crafted grammar of Kaplan et al. (2004). Preliminary work has been carried out to test the approach on languages other than English, providing proof of concept for the applicability of the method (Cahill et al., 2003; Cahill, 2004; Cahill et al., 2005). While first results have been promising, a number of important research questions have been raised. The original approach presented first in Cahill et al. (2002) is strongly tailored to English and the datastructures provided by the Penn-II treebank (Marcus et al., 1993). English is configurational and rather poor in inflectional forms. German, by contrast, features semi-free word order and a much richer morphology. Furthermore, treebanks for German differ considerably from the Penn-II treebank as regards data structures and encoding schemes underlying the grammar acquisition task. In my thesis I examine the impact of language-specific properties of German as well as linguistically motivated treebank design decisions on PCFG parsing and LFG grammar acquisition. I present experiments investigating the influence of treebank design on PCFG parsing and show which type of representations are useful for the PCFG and LFG grammar acquisition tasks. Furthermore, I present a novel approach to cross-treebank comparison, measuring the effect of controlled error insertion on treebank trees and parser output from different treebanks. I complement the cross-treebank comparison by providing a human evaluation using TePaCoC, a new testsuite for testing parser performance on complex grammatical constructions. Manual evaluation on TePaCoC data provides new insights on the impact of flat vs. hierarchical annotation schemes on data-driven parsing. I present treebank-based LFG acquisition methodologies for two German treebanks. An extensive evaluation along different dimensions complements the investigation and provides valuable insights for the future development of treebanks.
This dissertation explores the language of three German grammar books and accompanying exercise books which are produced in Germany for international students of German. It examines how the examples and exercises presented in these books constitute ‘colony texts’ which convey different representations of human activity to the reader. Analysis of the language used in the German grammar books centres on the Linguistics of Representation and borrows techniques used normally in Corpus Linguistics. By using WordSmith Tools this study shows how particular terms (nouns, verbs, adverbs and adjectives) occur with greater frequency than others in the books under analysis thereby representing certain human activities more strongly than others. The activity of ‘work*, in particular, emerges in the grammar books as a key human activity and consequently provides the main focus for analysis in this study. Concordances relating to ‘work’ are grouped and analysed in terms of what they reveal about popular professions, workplace hierarchy and attitudes and approaches to work. Findings are considered from three perspectives: what they reveal to the researcher and learners of German about the representation of ‘work’ in the chosen context, how they compare to findings from comparative analyses of German textbooks and how they can contribute to our overall understanding of ‘text*. Grammar book examples and exercises emerge as ‘texts’ which have significant potential to reflect cultural norms and attitudes despite being considered generally as a source of innocuous and unremarkable language.
Reduction in natural speech
(2009)
Natural (conversational) speech, compared to cannonical speech, is earmarked by the tremendous amount of variation that often leads to a massive change in pronunciation. Despite many attempts to explain and theorize the variability in conversational speech, its unique characteristics have not played a significant role in linguistic modeling. One of the reasons for variation in natural speech lies in a tendency of speakers to reduce speech, which may drastically alter the phonetic shape of words. Despite the massive loss of information due to reduction, listeners are often able to understand conversational speech even in the presence of background noise. This dissertation investigates two reduction processes, namely regressive place assimilation across word boundaries, and massive reduction and provides novel data from the analyses of speech corpora combined with experimental results from perception studies to reach a better understanding of how humans handle natural speech. The successes and failures of two models dealing with data from natural speech are presented: The FUL-model (Featurally Underspecified Lexicon, Lahiri & Reetz, 2002), and X-MOD (an episodic model, Johnson, 1997). Based on different assumptions, both models make different predictions for the two types of reduction processes under investigation. This dissertation explores the nature and dynamics of these processes in speech production and discusses its consequences for speech perception. More specifically, data from analyses of running speech are presented investigating the amount of reduction that occurs in naturally spoken German. Concerning production, the corpus analysis of regressive place assimilation reveals that it is not an obligatory process. At the same time, there emerges a clear asymmetry: With only very few exceptions, only [coronal] segments undergo assimilation, [labial] and [dorsal] segments usually do not. Furthermore, there seem to be cases of complete neutralization where the underlying Place of Articulation feature has undergone complete assimilation to the Place of Articulation feature of the upcoming segment. Phonetic analyses further underpin these findings. Concerning deletions and massive reductions, the results clearly indicate that phonological rules in the classical generative tradition are not able to explain the reduction patterns attested in conversational speech. Overall, the analyses of deletion and massive reduction in natural speech did not exhibit clear-cut patterns. For a more in-depth examination of reduction factors, the case of final /t/ deletion is examined by means of a new corpus constructed for this purpose. The analysis of this corpus indicates that although phonological context plays an important role on the deletion of segments (i.e. /t/), this arises in the form of tendencies, not absolute conditions. This is true for other deletion processes, too. Concerning speech perception, a crucial part for both models under investigation (X-MOD and FUL) is how listeners handle reduced speech. Five experiments investigate the way reduced speech is perceived by human listeners. Results from two experiments show that regressive place assimilations can be treated as instances of complete neutralizations by German listeners. Concerning massively reduced words, the outcome of transcription and priming experiments suggest that such words are not acceptable candidates of the intended lexical items for listeners in the absence of their proper phrasal context. Overall, the abstractionist FUL-model is found to be superior in explaining the data. While at first sight, X-MOD deals with the production data more readily, FUL provides a better fit for the perception results. Another important finding concerns the role of phonology and phonetics in general. The results presented in this dissertation make a strong case for models, such as FUL, where phonology and phonetics operate at different levels of the mental lexicon, rather than being integrated into one. The findings suggest that phonetic variation is not part of the representation in the mental lexicon.
