Participants listened to a short story where the recipient of an object was introduced with a reflexive, and were asked to identify the object recipient as quickly as possible. This allowed for the recording of participants' offline interpretation of the reflexive, response times, and eye movements on hearing the reflexive. Whilst our offline results show that the ultimate interpretation for reflexives was constrained by binding principles, the response time, and eye-movement data revealed that during processing participants were temporarily distracted by a structurally inappropriate competitor antecedent when this was prominent in the discourse. These results indicate that in addition to binding principles, online referential decisions are also affected by discourse-level information.

Here, we investigate these effects in the context of sentence processing: targets for retrieval during online sentence processing of English object relative clause constructions differ in the amount of elaboration associated with the target noun phrase, or the homogeneity of superficial features (text color). Experiment 1 shows that greater elaboration for targets during the encoding phase reduces reading times at retrieval sites, but elaboration of non-targets has considerably weaker effects. Experiment 2 illustrates that processing isolated superficial features of target noun phrases-here, a green word in a sentence with words colored white-does not lead to enhanced memory performance, despite triggering longer encoding times. These results are interpreted in the light of the memory models of Nairne, 1990, 2001, 2006, which state that encoding remnants contribute to the set of retrieval cues that provide the basis for similarity-based interference effects.

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. N2 - Das Ziel der vorliegenden Arbeit ist es zu untersuchen zu welchem Grad Satzverständnis kontextabhängig ist. In anderen Worten, werden die mentalen Prozesse die zum Satzverständnis beitragen davon beeinflusst mit welchem Ziel ein Satz gelesen wird? Ein in diesem Hinblick zentrales Phänomen ist die sogenannte ambiguity advantage, wonach ambige Sätze schneller gelesen werden als eindeutige. Dies erscheint zunächst kontraintuitiv, denn die Erstellung mehrerer Bedeutungen müsste mit einem höheren Verarbeitungsaufwand verbunden sein. Im Moment existieren zwei Theorien, die diesen Effekt erklären können: Das Unrestricted Race Model (URM; van Gompel, Pickering, and Traxler, 2000) basiert auf der Annahme, daß Leser, wann immer möglich, mehrere Interpretationen eines Satzes gleichzeitig zu erstellen versuchen. Sobald die erste Interpretation erstellt wurde, wird diese als die finale Interpretation des aktuellen Inputs akzeptiert, und die Erstellung weiterer Interpretationen wird terminiert. Weil die Dauer jedes Strukturerstellungsprozesses variiert, führt dieser Interpretationsmechanismus dazu daß Sätze mit mehreren Bedeutungen schneller verarbeitet werden. Wenn zwei Satzstrukturen zulässig sind, ist die Wahrscheinlichkeit höher daß zumindest eine von beiden relativ schnell berechnet wird als wenn nur eine Struktur zulässig ist. Dieses Modell nimmt keine Einflüsse von Verständnisaufgaben auf die Verarbeitungsstrategie an. Einen gänzlich anderen Erklärungsansatz verfolgt das strategische Unterspezifizierungsmodell von Swets et al. (2008). Hier wird angenommen daß Leser Ambiguitäten nur dann auflösen, wenn es unbedingt notwendig ist. Wenn es nicht notwendig ist, unterspezifizieren sie stattdessen. Laut dem Unterspezifizierungsmodell sind alle bisherigen Replikationen der ambiguity advantage der Tatsache geschuldet, daß in diesen Experimenten nur oberflächliche Fragen gestellt wurden, die keine Ambiguitätsauflösung erforderten. Wäre Disambiguierung erforderlich gewesen, wäre die Verarbeitung ambiger Sätze langsamer. In der vorliegenden Arbeit werden diese beiden Modelle der Ambiguitätsauflösung diskutiert und empirisch evaluiert. Zunächst wird diskutiert warum die Daten von Swets et al.'s (2008) Experiment keine Evidenz für Unterspezifikation darstellen. Als nächstes werden die präzisen quantitativen Vorhersagen des URM und des Unterspezifizierungsmodells diskutiert. Es werden die Resultate eines self-paced reading Experiments mit pränominalen Relativsätzen im Türkischen vorgestellt, welche nicht mit dem Unterspezifizierungsmodell kompatibel sind. Als nächstes werden die Resultate eines weiteren Experiments vorgestellt, welches den Prozess der Relativsatzanbindung im Deutschen im Speed-Accuracy Tradeoff Paradigma (SAT) untersucht. Die Resultate sind mit dem URM, aber nicht mit strategischer Unterspezifikation vereinbar. Des weiteren wird ein drittes Experiment vorgestellt, welches zeigt daß Parsingstrategien von den Gesichtspunkten abhängen unter denen Leser einen Satz lesen. Um alle experimentellen Ergebnisse in dieser Arbeit zu erklären, wird ein neues Modell der Disambiguierung vorgestellt: das Stochastic Multiple-Channel Model (SMCM). Es wird des weiteren gezeigt, daß die quantitativen Vorhersagen des SMCM mit den experimentellen Daten übereinstimmen.
