The findings presented herein integrate insights from research on eye-movement control and sentence comprehension during reading, addressing challenges in modeling time-ordered data, statistical inference, and interindividual variability. Using kernel density estimation and a pseudo-marginal likelihood for fixation durations and locations, a likelihood implementation of the SWIFT model of eye-movement control during reading (Engbert et al., Psychological Review, 112, 2005, pp. 777-813) is proposed. Within the broader framework of data assimilation, Bayesian parameter inference with adaptive Markov Chain Monte Carlo techniques is facilitated for reliable model fitting. Across the different studies, this framework has shown to enable reliable parameter recovery from simulated data and prediction of experimental summary statistics. Despite its complexity, SWIFT can be fitted within a principled Bayesian workflow, capturing interindividual differences and modeling experimental effects on reading across different geometrical alterations of text. Based on these advancements, the integrated dynamical model SEAM is proposed, which combines eye-movement control, a traditionally psychological research area, and post-lexical language processing in the form of cue-based memory retrieval (Lewis \& Vasishth, Cognitive Science, 29, 2005, pp. 375-419), typically the purview of psycholinguistics. This proof-of-concept integration marks a significant step forward in natural language comprehension during reading and suggests that the presented methodology can be useful to develop complex cognitive dynamical models that integrate processes at levels of perception, higher cognition, and (oculo-)motor control. These findings collectively advance process-oriented cognitive modeling and highlight the importance of Bayesian inference, individual differences, and interdisciplinary integration for a holistic understanding of reading processes. Implications for theory and methodology, including proposals for model comparison and hierarchical parameter inference, are briefly discussed.}, language = {en} } @phdthesis{Mertzen2022, author = {Mertzen, Daniela}, title = {A cross-linguistic investigation of similarity-based interference in sentence comprehension}, doi = {10.25932/publishup-55668}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-556685}, school = {Universit{\"a}t Potsdam}, pages = {xvii, 129}, year = {2022}, abstract = {The aim of this dissertation was to conduct a larger-scale cross-linguistic empirical investigation of similarity-based interference effects in sentence comprehension. Interference studies can offer valuable insights into the mechanisms that are involved in long-distance dependency completion. Many studies have investigated similarity-based interference effects, showing that syntactic and semantic information are employed during long-distance dependency formation (e.g., Arnett \& Wagers, 2017; Cunnings \& Sturt, 2018; Van Dyke, 2007, Van Dyke \& Lewis, 2003; Van Dyke \& McElree, 2011). Nevertheless, there are some important open questions in the interference literature that are critical to our understanding of the constraints involved in dependency resolution. The first research question concerns the relative timing of syntactic and semantic interference in online sentence comprehension. Only few interference studies have investigated this question, and, to date, there is not enough data to draw conclusions with regard to their time course (Van Dyke, 2007; Van Dyke \& McElree, 2011). Our first cross-linguistic study explores the relative timing of syntactic and semantic interference in two eye-tracking reading experiments that implement the study design used in Van Dyke (2007). The first experiment tests English sentences. The second, larger-sample experiment investigates the two interference types in German. Overall, the data suggest that syntactic and semantic interference can arise simultaneously during retrieval. The second research question concerns a special case of semantic interference: We investigate whether cue-based retrieval interference can be caused by semantically similar items which are not embedded in a syntactic structure. This second interference study builds on a landmark study by Van Dyke \& McElree (2006). The study design used in their study is unique in that it is able to pin down the source of interference as a consequence of cue overload during retrieval, when semantic retrieval cues do not uniquely match the retrieval target. Unlike most other interference studies, this design is able to rule out encoding interference as an alternative explanation. Encoding accounts postulate that it is not cue overload at the retrieval site but the erroneous encoding of similar linguistic items in memory that leads to interference (Lewandowsky et al., 2008; Oberauer \& Kliegl, 2006). While Van Dyke \& McElree (2006) reported cue-based retrieval interference from sentence-external distractors, the evidence for this effect was weak. A subsequent study did not show interference of this type (Van Dyke et al., 2014). Given these inconclusive findings, further research is necessary to investigate semantic cue-based retrieval interference. The second study in this dissertation provides a larger-scale cross-linguistic investigation of cue-based retrieval interference from sentence-external items. Three larger-sample eye-tracking studies in English, German, and Russian tested cue-based interference in the online processing of filler-gap dependencies. This study further extends the previous research by investigating interference in each language under varying task demands (Logačev \& Vasishth, 2016; Swets et al., 2008). Overall, we see some very modest support for proactive cue-based retrieval interference in English. Unexpectedly, this was observed only under a low task demand. In German and Russian, there is some evidence against the interference effect. It is possible that interference is attenuated in languages with richer case marking. In sum, the cross-linguistic experiments on the time course of syntactic and semantic interference from sentence-internal distractors support existing evidence of syntactic and semantic interference during sentence comprehension. Our data further show that both types of interference effects can arise simultaneously. Our cross-linguistic experiments investigating semantic cue-based retrieval interference from sentence-external distractors suggest that this type of interference may arise only in specific linguistic contexts.}, language = {en} } @phdthesis{Farhy2019, author = {Farhy, Yael}, title = {Universals and particulars in morphology}, doi = {10.25932/publishup-47003}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-470033}, school = {Universit{\"a}t Potsdam}, pages = {VI, 167}, year = {2019}, abstract = {For many years, psycholinguistic evidence has been predominantly based on findings from native speakers of Indo-European languages, primarily English, thus providing a rather limited perspective into the human language system. In recent years a growing body of experimental research has been devoted to broadening this picture, testing a wide range of speakers and languages, aiming to understanding the factors that lead to variability in linguistic performance. The present dissertation investigates sources of variability within the morphological domain, examining how and to what extent morphological processes and representations are shaped by specific properties of languages and speakers. Firstly, the present work focuses on a less explored language, Hebrew, to investigate how the unique non-concatenative morphological structure of Hebrew, namely a non-linear combination of consonantal roots and vowel patterns to form lexical entries (L-M-D + CiCeC = limed 'teach'), affects morphological processes and representations in the Hebrew lexicon. Secondly, a less investigated population was tested: late learners of a second language. We directly compare native (L1) and non-native (L2) speakers, specifically highly proficient and immersed late learners of Hebrew. Throughout all publications, we have focused on a morphological phenomenon of inflectional classes (called binyanim; singular: binyan), comparing productive (class Piel, e.g., limed 'teach') and unproductive (class Paal, e.g., lamad 'learn') verbal inflectional classes. By using this test case, two psycholinguistic aspects of morphology were examined: (i) how morphological structure affects online recognition of complex words, using masked priming (Publications I and II) and cross-modal priming (Publication III) techniques, and (ii) what type of cues are used when extending morpho-phonological patterns to novel complex forms, a process referred to as morphological generalization, using an elicited production task (Publication IV). The findings obtained in the four manuscripts, either published or under review, provide significant insights into the role of productivity in Hebrew morphological processing and generalization in L1 and L2 speakers. Firstly, the present L1 data revealed a close relationship between productivity of Hebrew verbal classes and recognition process, as revealed in both priming techniques. The consonantal root was accessed only in the productive class (Piel) but not the unproductive class (Paal). Another dissociation between the two classes was revealed in the cross-modal priming, yielding a semantic relatedness effect only for Paal but not Piel primes. These findings are taken to reflect that the Hebrew mental representations display a balance between stored undecomposable unstructured stems (Paal) and decomposed structured stems (Piel), in a similar manner to a typical dual-route architecture, showing that the Hebrew mental lexicon is less unique than previously claimed in psycholinguistic research. The results of the generalization study, however, indicate that there are still substantial differences between inflectional classes of Hebrew and other Indo-European classes, particularly in the type of information they rely on in generalization to novel forms. Hebrew binyan generalization relies more on cues of argument structure and less on phonological cues. Secondly, clear L1/L2 differences were observed in the sensitivity to abstract morphological and morpho-syntactic information during complex word recognition and generalization. While L1 Hebrew speakers were sensitive to the binyan information during recognition, expressed by the contrast in root priming, L2 speakers showed similar root priming effects for both classes, but only when the primes were presented in an infinitive form. A root priming effect was not obtained for primes in a finite form. These patterns are interpreted as evidence for a reduced sensitivity of L2 speakers to morphological information, such as information about inflectional classes, and evidence for processing costs in recognition of forms carrying complex morpho-syntactic information. Reduced reliance on structural information cues was found in production of novel verbal forms, when the L2 group displayed a weaker effect of argument structure for Piel responses, in comparison to the L1 group. Given the L2 results, we suggest that morphological and morphosyntactic information remains challenging for late bilinguals, even at high proficiency levels.}, language = {en} } @phdthesis{Paape2017, author = {Paape, Dario L.

Murphy (1985) hypothesized that ellipsis is resolved via a string copying procedure when the antecedent is within the same sentence, and that copying longer strings takes more time. Such an account also implies that the antecedent is copied without its structure, which in turn implies that recomputing its syntax and semantics may be necessary at the ellipsis gap. Alternatively, several accounts predict null effects of antecedent complexity, as well as no reparsing. These either involve a structure copying mechanism that is cost-free and whose finishing time is thus independent of the form of the antecedent (Frazier \& Clifton, 2001), treat ellipsis as a pointer into content-addressable memory with direct access (Martin \& McElree, 2008, 2009), or assume that one structure is 'shared' between antecedent and gap (Frazier \& Clifton, 2005). In a self-paced reading study on German sluicing, temporarily ambiguous garden-path clauses were used as antecedents, but no evidence of reparsing in the form of a slowdown at the ellipsis site was found. Instead, results suggest that antecedents which had been reanalyzed from an initially incorrect structure were easier to retrieve at the gap. This finding that can be explained within the framework of cue-based retrieval parsing (Lewis \& Vasishth, 2005), where additional syntactic operations on a structure yield memory reactivation effects. Two further self-paced reading studies on German bare argument ellipsis and English verb phrase ellipsis investigated if adding linguistic content to the antecedent would increase processing times for the ellipsis, and whether insufficiently demanding comprehension tasks may have been responsible for earlier null results (Frazier \& Clifton, 2000; Martin \& McElree, 2008). It has also been suggested that increased antecedent complexity should shorten rather than lengthen retrieval times by providing more unique memory features (Hofmeister, 2011). Both experiments failed to yield reliable evidence that antecedent complexity affects ellipsis processing times in either direction, irrespectively of task demands. Finally, two eye-tracking studies probed more deeply into the proposed reactivation-induced speedup found in the first experiment. The first study used three different kinds of French garden-path sentences as antecedents, with two of them failing to yield evidence for reactivation. Moreover, the third sentence type showed evidence suggesting that having failed to assign a structure to the antecedent leads to a slowdown at the ellipsis site, as well as regressions towards the ambiguous part of the sentence. The second eye-tracking study used the same materials as the initial self-paced reading study on German, with results showing a pattern similar to the one originally observed, with some notable differences. Overall, the experimental results are compatible with the view that adding linguistic material to the antecedent has no or very little effect on the ease with which ellipsis is resolved, which is consistent with the predictions of cost-free copying, pointer-based approaches and structure sharing. Additionally, effects of the antecedent's parsing history on ellipsis processing may be due to reactivation, the availability of multiple representations in memory, or complete failure to retrieve a matching target.}, language = {en} } @phdthesis{Jaeger2015, author = {J{\"a}ger, Lena Ann}, title = {Working memory and prediction in human sentence parsing}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-82517}, school = {Universit{\"a}t Potsdam}, pages = {xi, 144}, year = {2015}, abstract = {This dissertation investigates the working memory mechanism subserving human sentence processing and its relative contribution to processing difficulty as compared to syntactic prediction. Within the last decades, evidence for a content-addressable memory system underlying human cognition in general has accumulated (e.g., Anderson et al., 2004). In sentence processing research, it has been proposed that this general content-addressable architecture is also used for language processing (e.g., McElree, 2000). Although there is a growing body of evidence from various kinds of linguistic dependencies that is consistent with a general content-addressable memory subserving sentence processing (e.g., McElree et al., 2003; VanDyke2006), the case of reflexive-antecedent dependencies has challenged this view. It has been proposed that in the processing of reflexive-antecedent dependencies, a syntactic-structure based memory access is used rather than cue-based retrieval within a content-addressable framework (e.g., Sturt, 2003). Two eye-tracking experiments on Chinese reflexives were designed to tease apart accounts assuming a syntactic-structure based memory access mechanism from cue-based retrieval (implemented in ACT-R as proposed by Lewis and Vasishth (2005). In both experiments, interference effects were observed from noun phrases which syntactically do not qualify as the reflexive's antecedent but match the animacy requirement the reflexive imposes on its antecedent. These results are interpreted as evidence against a purely syntactic-structure based memory access. However, the exact pattern of effects observed in the data is only partially compatible with the Lewis and Vasishth cue-based parsing model. Therefore, an extension of the Lewis and Vasishth model is proposed. Two principles are added to the original model, namely 'cue confusion' and 'distractor prominence'. Although interference effects are generally interpreted in favor of a content-addressable memory architecture, an alternative explanation for interference effects in reflexive processing has been proposed which, crucially, might reconcile interference effects with a structure-based account. It has been argued that interference effects do not necessarily reflect cue-based retrieval interference in a content-addressable memory but might equally well be accounted for by interference effects which have already occurred at the moment of encoding the antecedent in memory (Dillon, 2011). Three experiments (eye-tracking and self-paced reading) on German reflexives and Swedish possessives were designed to tease apart cue-based retrieval interference from encoding interference. The results of all three experiments suggest that there is no evidence that encoding interference affects the retrieval of a reflexive's antecedent. Taken together, these findings suggest that the processing of reflexives can be explained with the same cue-based retrieval mechanism that has been invoked to explain syntactic dependency resolution in a range of other structures. This supports the view that the language processing system is located within a general cognitive architecture, with a general-purpose content-addressable working memory system operating on linguistic expressions. Finally, two experiments (self-paced reading and eye-tracking) using Chinese relative clauses were conducted to determine the relative contribution to sentence processing difficulty of working-memory processes as compared to syntactic prediction during incremental parsing. Chinese has the cross-linguistically rare property of being a language with subject-verb-object word order and pre-nominal relative clauses. This property leads to opposing predictions of expectation-based accounts and memory-based accounts with respect to the relative processing difficulty of subject vs. object relatives. Previous studies showed contradictory results, which has been attributed to different kinds local ambiguities confounding the materials (Lin and Bever, 2011). The two experiments presented are the first to compare Chinese relatives clauses in syntactically unambiguous contexts. The results of both experiments were consistent with the predictions of the expectation-based account of sentence processing but not with the memory-based account. From these findings, I conclude that any theory of human sentence processing needs to take into account the power of predictive processes unfolding in the human mind.}, language = {en} } @phdthesis{Logačev2014, author = {Logačev, Pavel}, title = {Underspecification and parallel processing in sentence comprehension}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-82047}, school = {Universit{\"a}t Potsdam}, year = {2014}, abstract = {The aim of the present thesis is to answer the question to what degree the processes involved in sentence comprehension are sensitive to task demands. A central phenomenon in this regard is the so-called ambiguity advantage, which is the finding that ambiguous sentences can be easier to process than unambiguous sentences. This finding may appear counterintuitive, because more meanings should be associated with a higher computational effort. Currently, two theories exist that can explain this finding. The Unrestricted Race Model (URM) by van Gompel et al. (2001) assumes that several sentence interpretations are computed in parallel, whenever possible, and that the first interpretation to be computed is assigned to the sentence. Because the duration of each structure-building process varies from trial to trial, the parallelism in structure-building predicts that ambiguous sentences should be processed faster. This is because when two structures are permissible, the chances that some interpretation will be computed quickly are higher than when only one specific structure is permissible. Importantly, the URM is not sensitive to task demands such as the type of comprehension questions being asked. A radically different proposal is the strategic underspecification model by Swets et al. (2008). It assumes that readers do not attempt to resolve ambiguities unless it is absolutely necessary. In other words, they underspecify. According the strategic underspecification hypothesis, all attested replications of the ambiguity advantage are due to the fact that in those experiments, readers were not required to fully understand the sentence. In this thesis, these two models of the parser's actions at choice-points in the sentence are presented and evaluated. First, it is argued that the Swets et al.'s (2008) evidence against the URM and in favor of underspecification is inconclusive. Next, the precise predictions of the URM as well as the underspecification model are refined. Subsequently, a self-paced reading experiment involving the attachment of pre-nominal relative clauses in Turkish is presented, which provides evidence against strategical underspecification. A further experiment is presented which investigated relative clause attachment in German using the speed-accuracy tradeoff (SAT) paradigm. The experiment provides evidence against strategic underspecification and in favor of the URM. Furthermore the results of the experiment are used to argue that human sentence comprehension is fallible, and that theories of parsing should be able to account for that fact. Finally, a third experiment is presented, which provides evidence for the sensitivity to task demands in the treatment of ambiguities. Because this finding is incompatible with the URM, and because the strategic underspecification model has been ruled out, a new model of ambiguity resolution is proposed: the stochastic multiple-channel model of ambiguity resolution (SMCM). It is further shown that the quantitative predictions of the SMCM are in agreement with experimental data. In conclusion, it is argued that the human sentence comprehension system is parallel and fallible, and that it is sensitive to task-demands.}, language = {en} } @phdthesis{Gerth2015, author = {Gerth, Sabrina}, title = {Memory limitations in sentence comprehension}, isbn = {978-3-86956-321-3}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-71554}, school = {Universit{\"a}t Potsdam}, pages = {xviii, 157}, year = {2015}, abstract = {This dissertation addresses the question of how linguistic structures can be represented in working memory. We propose a memory-based computational model that derives offline and online complexity profiles in terms of a top-down parser for minimalist grammars (Stabler, 2011). The complexity metric reflects the amount of time an item is stored in memory. The presented architecture links grammatical representations stored in memory directly to the cognitive behavior by deriving predictions about sentence processing difficulty. Results from five different sentence comprehension experiments were used to evaluate the model's assumptions about memory limitations. The predictions of the complexity metric were compared to the locality (integration and storage) cost metric of Dependency Locality Theory (Gibson, 2000). Both metrics make comparable offline and online predictions for four of the five phenomena. The key difference between the two metrics is that the proposed complexity metric accounts for the structural complexity of intervening material. In contrast, DLT's integration cost metric considers the number of discourse referents, not the syntactic structural complexity. We conclude that the syntactic analysis plays a significant role in memory requirements of parsing.

Rules of grammar enable us to produce and understand complex phrases we have not encountered before and at the same time constrain the computation of complex expressions.

Regular verbs (e.g. walk-walked) are computed using a suffixation rule in a neural system for grammatical processing; non-regular verbs (run-ran) are retrieved from associative memory. The role of regularity has only been explored for the past tense, where regularity is overtly visible. To explore the representation and encoding of regularity as well as the inflectional processes involved in the production of regular and non-regular verbs, this dissertation investigated three groups of German verbs: regular, irregular and hybrid verbs. Hybrid verbs in German have completely regular conjugation in the present tense and irregular conjugation in the past tense. Articulation latencies were measured while participants named pictures of actions, producing the 3rd person singular of regular, hybrid, and irregular verbs in present and past tense.
