TY - JOUR A1 - Patil, Umesh A1 - Vasishth, Shravan A1 - Lewis, Richard L. T1 - Retrieval Interference in Syntactic Processing: The Case of Reflexive Binding in English JF - Frontiers in psychology N2 - It has been proposed that in online sentence comprehension the dependency between a reflexive pronoun such as himself/herself and its antecedent is resolved using exclusively syntactic constraints. Under this strictly syntactic search account, Principle A of the binding theory—which requires that the antecedent c-command the reflexive within the same clause that the reflexive occurs in—constrains the parser's search for an antecedent. The parser thus ignores candidate antecedents that might match agreement features of the reflexive (e.g., gender) but are ineligible as potential antecedents because they are in structurally illicit positions. An alternative possibility accords no special status to structural constraints: in addition to using Principle A, the parser also uses non-structural cues such as gender to access the antecedent. According to cue-based retrieval theories of memory (e.g., Lewis and Vasishth, 2005), the use of non-structural cues should result in increased retrieval times and occasional errors when candidates partially match the cues, even if the candidates are in structurally illicit positions. In this paper, we first show how the retrieval processes that underlie the reflexive binding are naturally realized in the Lewis and Vasishth (2005) model. We present the predictions of the model under the assumption that both structural and non-structural cues are used during retrieval, and provide a critical analysis of previous empirical studies that failed to find evidence for the use of non-structural cues, suggesting that these failures may be Type II errors. We use this analysis and the results of further modeling to motivate a new empirical design that we use in an eye tracking study. The results of this study confirm the key predictions of the model concerning the use of non-structural cues, and are inconsistent with the strictly syntactic search account. These results present a challenge for theories advocating the infallibility of the human parser in the case of reflexive resolution, and provide support for the inclusion of agreement features such as gender in the set of retrieval cues.

However, the precise degree of detail in early words requires further investigation due to equivocal findings. We studied this question by assessing children’s sensitivity to the degree of featural manipulation (Chapters 2 and 3), and sensitivity to the featural makeup of homorganic and heterorganic consonant clusters (Chapter 4). Gradient sensitivity on the one hand and sensitivity to homorganicity on the other hand would suggest that lexical processing makes use of sub-phonemic information, which in turn would indicate that early words contain sub-phonemic detail. The studies presented in this thesis assess children’s sensitivity to sub-phonemic detail using minimally demanding online paradigms suitable for infants: single-picture pupillometry and intermodal preferential looking. Such paradigms have the potential to uncover lexical knowledge that may be masked otherwise due to cognitive limitations. The study reported in Chapter 2 obtained a differential response in pupil dilation to the degree of featural manipulation, a result consistent with gradient sensitivity. The study reported in Chapter 3 obtained a differential response in proportion of looking time and pupil dilation to the degree of featural manipulation, a result again consistent with gradient sensitivity. The study reported in Chapter 4 obtained a differential response to the manipulation of homorganic and heterorganic consonant clusters, a result consistent with sensitivity to homorganicity. These results suggest that infants' lexical representations are not only specific, but also detailed to the extent that they contain sub-phonemic information. N2 - Die lexikalische Verarbeitung bei Kleinkindern kann durch die Manipulation von phonologischen Merkmalen moduliert werden. Dies deutet darauf hin, dass frühe lexikalische Repräsentationen hinreichend spezifiziert sind, um einen Abgleich mit einem gehörten Wort herzustellen. Aufgrund von nicht einheitlichen Befunden ist jedoch weitere Forschung notwendig, um zu bestimmen, wie detailliert erste Wörter repräsentiert werden. Dieser Frage wurde nachgegangen, indem die Sensitivität der Kinder gegenüber dem Grad der Merkmalmanipulation (Kapitel 2 und 3) und gegenüber homorganischen und heterorganischen Konsonantenclustern (Kapitel 4) untersucht wurde. Eine gradiente Sensitivität gegenüber der Manipulation phonologischer Merkmale und eine Sensitivität gegenüber der Homorganizität deuten darauf hin, dass Gradientenempfindlichkeit auf der einen Seite und die Empfindlichkeit gegenüber der für die lexikalische Verarbeitung subphonemische Informationen relevant sind, was wiederum darauf schließen lässt, dass lexikalische Repräsentationen subphonemische Details enthalten. Die Studien, die in dieser Arbeit vorgestellt werden, untersuchen die Sensitivität von 30 Monate alten Kindern für subphonemische Details mit Online-Paradigmen, die für Kleinkinder geeignet sind: Einzelbild-Pupillometrie und "intermodal preferential looking". Diese Paradigmen haben das Potenzial, lexikalisches Wissen aufzudecken, das sonst aufgrund kognitiver Beanspruchungen verdeckt bleibt. Die in Kapitel 2 berichtete Studie zeigt eine differenzielle Reaktion in der Pupillendilatation in Verbindung mit dem Grad der Merkmalsmanipulation, ein Ergebnis, das die Sensitivität gegenüber der Gradienz der phonologischen Distanz nahelegt. Die Studie in Kapitel 3 zeigt eine differenzielle Reaktion sowohl in der Pupillendilatation auch in den Blickzeiten in Abhängigkeit vom Grad der phonologischen Merkmalmanipulation, ein Ergebnis das das der Studie 2 unterstützt. Die in Kapitel 4 berichtete Studie zeigt Unterschiede in der Pupillendilation nur in Reaktion auf eine phonologische Manipulation der homorganischen nicht aber der heterorganischen Konsonantencluster. Dieses Ergebnis stützt die Annahme, einer frühen Sensitivität gegenüber Homorganizität. Diese Ergebnisse deuten darauf hin, dass die lexikalischen Repräsentationen von Kleinkindern nicht nur spezifisch, sondern auch detailliert sind, da sie subphonemische Informationen enthalten.
