Exploring generalisation following treatment of language deficits in aphasia can provide insights into the functional relation of the cognitive processing systems involved. In the present study, we first review treatment outcomes of interventions targeting sentence processing deficits and, second report a treatment study examining the occurrence of...
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...
This study investigated the effects of syntactically marked and enhanced prosody on local ambiguity resolution in German SVO and OVS sentences. In a visual-world experiment, thirty younger and thirty elderly healthy participants performed a sentence-picture matching task. Response accuracy, reaction times and fixations proportions to the target pic...
The aim of the study is to investigate the situational (in)dependence of production of prosodic boundary cues in an interactive setting. A game-like task was designed in which we tested whether native German speakers, when asked to repeat, change their speaking style while communicating with a confederate listener. In the task, they produced coordi...
Background
Prosody serves central functions in language processing including linguistic functions (linguistic prosody), like structuring the speech signal. Impairments in production and comprehension of linguistic prosody have been described for persons with unilateral right (RHDP) or left hemisphere damage (LHDP). However, reported results differ...
Purpose:
Persons with unilateral brain damage in the right hemisphere (RH) or left hemisphere (LH) show limitations in processing linguistic prosody, with yet inconclusive results on their ability to process prosodically marked structural boundaries for syntactic ambiguity resolution. We aimed at systematically investigating production and compreh...
Prosodic cues help to disambiguate incoming information in spoken language perception. In structurally ambiguous coordinate utterances, such as three-name sequences, the intended grouping is marked by three prosodic cues: F0-range, final lengthening, and pause. To indicate that the first two names are grouped together, speakers typically weaken the...
The German case marking system contains case syncretisms,which, along with a relatively free word order, can lead to sen-tences with local ambiguities, for instance, SVO and OVS sen-tences with string-identical noun phrases (NPs) in sentence-initial position. Prosodic marking constitutes one possibilityfor ambiguity resolution. Perception studies s...

In unserer Studie untersuchen wir die rezeptiven Fähigkeiten zur Identifikation prosodisch markierter Grenzen von P-RHL und P-LHL bei unterschiedlicher Kombination und Ausprägung der drei prosodischen Cues Pausendauer, f0-Variation und finale Längung.
People with right hemisphere brain lesions (PRHL) are often faced with impairments
in their communicative abilities, which can impact their participation. These impairments
may be related to diminished executive functions and/or reduced attentional or
socio-cognitive capacities. PRHL can also be a!ected by deficits in processing of linguistic
proso...
Prosodic boundaries can be used to disambiguate the syntactic structure of coordinated name sequences ('coordinates'). To answer the question whether disambiguating prosody is produced in a situationally dependent or independent manner and to contribute to our understanding of the nature of the prosody-syntax link, we systematically explored variab...
Speech perception study that makes use of a gating paradigm to test if it is possible to reliably detect intended grouping of a coordinate structure by exploiting prosodic information already before the Intonation Phrase Boundary that contains the strongest prosodic cues. Results from human listeners are compared to results from machine learning mo...
This poster presents my empirical bachelor thesis. Herbert, Hickin, Howard, Osborne and Best (2008) have developed a protocol to measure the conversational performance of people with aphasia (PwA) and in particular to measure possible transfer of improvements to spontaneous speech after word retrieval therapy.
The aim of the empirical work was to...
The age at which members of a semantic category are learned (age of acquisition), the typicality they demonstrate within their corresponding category, and the semantic domain to which they belong (living, non-living) are known to influence the speed and accuracy of lexical/semantic processing. So far, only a few studies have looked at the origin of...

Individuals with agrammatic Broca's aphasia experience difficulty when processing reversible non-canonical sentences. 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,...
Individuals with agrammatic Broca's aphasia perform at chance level when processing reversible non-canonical sentences. Representational accounts (e.g., Grodzinsky, 1995, 2000, 2006) attribute this deficit to an impairment in syntactic representations. Processing accounts (e.g., Haarmann, Just, & Carpenter, 1997; Caplan, Waters, Dede, Michaud, & Re...
Background:
Individuals with agrammatic aphasia (IWAs) have problems with grammatical decoding of tense inflection. However, these difficulties depend on the time frame that the tense refers to. Verb morphology with reference to the past is more difficult than with reference to the non-past, because a link needs to be made to the past event in dis...

Background: In behavioral tests of sentence comprehension in aphasia, correct and
Sentence processing deficits in aphasia become evident whenever patients have to rely on syntactic structure in order to derive the correct sentence interpretation. Aphasics are known to have difficulty in comprehending reversible non-canonical word order sentences compared to canonical word order (cf. Mitchum & Berndt, 2008). Representational acco...
Background: In addition to the canonical subject-verb-object (SVO) word order, German also allows for non-canonical order (OVS), and the case-marking system supports thematic role interpretation. Previous eye-tracking studies (Kamide et al., 2003; Knoeferle, 2007) have shown that unambiguous case information in non-canonical sentences is processed...
