Different accounts have been proposed to explain this phenomenon. The Trace Deletion account (Grodzinsky, 1995, 2000, 2006) attributes this deficit to an impairment in syntactic representations, whereas others (e.g., Caplan, Waters, Dede, Michaud, \& Reddy, 2007; Haarmann, Just, \& Carpenter, 1997) propose that the underlying structural representations are unimpaired, but sentence comprehension is affected by processing deficits, such as slow lexical activation, reduction in memory resources, slowed processing and/or intermittent deficiency, among others. We test the claims of two processing accounts, slowed processing and intermittent deficiency, and two versions of the Trace Deletion Hypothesis (TDH), in a computational framework for sentence processing (Lewis \& Vasishth, 2005) implemented in ACT-R (Anderson, Byrne, Douglass, Lebiere, \& Qin, 2004). The assumption of slowed processing is operationalized as slow procedural memory, so that each processing action is performed slower than normal, and intermittent deficiency as extra noise in the procedural memory, so that the parsing steps are more noisy than normal. We operationalize the TDH as an absence of trace information in the parse tree. To test the predictions of the models implementing these theories, we use the data from a German sentence—picture matching study reported in Hanne, Sekerina, Vasishth, Burchert, and De Bleser (2011). The data consist of offline (sentence-picture matching accuracies and response times) and online (eye fixation proportions) measures. From among the models considered, the model assuming that both slowed processing and intermittent deficiency are present emerges as the best model of sentence processing difficulty in aphasia. The modeling of individual differences suggests that, if we assume that patients have both slowed processing and intermittent deficiency, they have them in differing degrees.}, language = {en} } @article{HanneBurchertVasishth2016, author = {Hanne, Sandra and Burchert, Frank and Vasishth, Shravan}, title = {On the nature of the subject-object asymmetry in wh-question comprehension in aphasia: evidence from eye tracking}, series = {Aphasiology : an international, interdisciplinary journal}, volume = {30}, journal = {Aphasiology : an international, interdisciplinary journal}, publisher = {American Chemical Society}, address = {Abingdon}, issn = {0268-7038}, doi = {10.1080/02687038.2015.1065469}, pages = {435 -- 462}, year = {2016}, abstract = {Background: Individuals with aphasia (IWA) show deficits in comprehending object-extracted declaratives while comprehension of subject-extracted structures is relatively preserved. It is a matter of debate whether this subject-object asymmetry also arises for comprehension of wh-questions. Successful comprehension of wh-questions critically entails correct resolution of a filler-gap dependency. Most previous studies have used only offline accuracy measures to investigate wh-question comprehension in aphasia. Online studies exploring syntactic processing in real time are needed in order to draw inferences about gap-filling abilities in IWA and to identify the point of breakdown in sentence comprehension. Aims: This study aimed at investigating processing of subject and object who-questions in German-speaking IWA and in a group of controls by combining an offline and online method. We further aimed to explore the impact of case-marking cues on processing of wh-questions. Methods \& Procedures: Applying a variant of the visual world eye-tracking paradigm, we measured participants' eye movements while they performed the same offline task, which is frequently used to assess comprehension of declaratives (sentence-picture matching). Outcomes \& Results: Concerning online processing of who-questions in controls, we found anticipation of the most likely post-verbal theta-role immediately after processing the case-marked wh-pronoun in both subject and object questions. In addition, we observed an unexpected advantage of object over subject questions in terms of processing time. The offline results for IWA revealed that there were three heterogeneous patterns: (a) symmetrical comprehension with equal impairments for both question types, (b) asymmetrical performance with better comprehension of subject than object who-questions, and (c) a reversed asymmetry with better comprehension of object as compared to subject questions. For online processing of both types of who-questions, IWA showed retained abilities in postulating the gap and in associating the filler with this gap, although they were slower as compared to controls. Moreover, similarly to controls, they anticipated the most likely post-verbal theta-role. Conclusions: For controls, the findings provide evidence for rapid resolution of the filler-gap dependency and incremental processing of case-marking cues, reflected in early prediction of upcoming syntactic structure. We attribute faster processing of object questions to faster alignment of the anticipated element with a semantically more salient character. For IWA, the online data provide evidence for retained predictive abilities in processing of filler-gap dependencies in wh-questions, but prediction was delayed. This is most likely attributed to delayed integration of case-marking cues.}, language = {en} } @misc{CorstenGuentherNieslonyetal.2016, author = {Corsten, Sabine and G{\"u}nther, Thomas and Nieslony, Julia and Fl{\"o}ther, Manfred and Rott, Anke and Sch{\"o}ppe, Doreen and K{\"o}sterke-Buchardt, Antje and Machleb, Franziska and Purat, Patricia and Euler, Harald A. and Breitenstein, Sarah and D{\"u}sterh{\"o}ft, Stefanie and Posse, Dorothea and Topaj, Nathalie and Golcher, Felix and Gagarina, Natalʹja Vladimirovna and Stegenwallner-Sch{\"u}tz, Maja Henny Katherine and Lassotta, Romy and Ferchland, Lisa and Adani, Flavia and Wotschack, Christiane and Klassert, Annegret and Festman, Julia and Schumacher, Rebecca and Burchert, Frank and Ablinger, Irene and Buttler, Rahel and Frank, Luis and Stadie, Nicole and Weiland, Linda and Netzebandt, Jonka and Frank, Ulrike and Bykova, Ksenia and Loppnow, Anna and Huckabee, Maggie-Lee and Krusche, Lisa}, title = {Spektrum Patholinguistik Band 9.
