Zur Bewertung zentraler Sprachstörungen mittels objektiver Kriterien: Ein psychophysiologischer Beitrag zur Diskussion der Neuroplastizitätshypothese
1992
Examinations of aphasic patients by using cognitive tasks were based on the hypothesis that semantically evoked potentials correlate to the processing of information in the different speech processing of information in the different speech processing areas. It was found that patients with Broca aphasia generated synchronization potentials in the Wernicke area in contrast to Wernicke patients. We suppose a correlation between the timing in sensorial speech processing areas and the generation of synchronization potentials.
Proximal and distal. Rethinking linguistic form and use for clinical purposes.
2010
With clinical purposes in mind, a review of the proximal/distal opposition is carried out in order to define a universal parameter of variability in semiotic procedures. By taking into consideration different-although notionally inter-related-senses of the proximal/distal opposition, a cluster of semiotic properties is proposed, which initially permits one to characterize dimensions of variability in the form and use of gestures. The subsequent and central aim of this paper is, however, to demonstrate that the same, or homologous, properties can also serve to characterize variability in the use of language, by assuming a basic connection between gesturing and linguistic behaviour. The main …
On natural metalinguistic abilities in aphasia: a preliminary study
2012
Background: Natural metalinguistic abilities, which are put into play without explicit instructions, constitute the cognitive basis for a “reflexive” use of language, a particular manifestation of the executive function when applied to language and verbal behaviour. This reflexive use entails a specific attentional activity by speakers and hearers with regard to linguistic outputs, and an intentional experience-based control over the language use. Putting into play natural metalinguistic abilities can be considered a significant factor for explaining different kinds of adaptive processes. Aims: Preliminary research on natural metalinguistic abilities as manifested in people with aphasia wil…
On aphasia and communicative speech therapy: Once more
1994
Abstract In my paper I tried to emphasize the idea of communication as a process in which one's informative intention is made evident by coded or non-coded verbal and non-verbal means and in co-operation with other interlocutors. Furthermore, I presented some general goals of a communicative speech therapy and then demonstrated what kind of consequences they would have on the study of aphasic communication.
Aphasia rehabilitation from a pragmatic-functional paradigm. A comparative study of two patients with different performance profiles in natural metal…

Background: The rehabilitation of people with aphasia is a classic research topic, on which different orientations can be observed according to the theory behind the rehabilitation techniques used....
Joint planning in conversations with a person with aphasia
2021
Abstract This study explores practices employed by a person with aphasia (PWA) and his wife to organize joint planning sequences and negotiate deontic rights (a participants' entitlement to initiate planning sequences and the entitlement to accept or reject a plan). We analyze two different conversations between a man with aphasia and his wife and their adult daughter. Using Conversation Analysis (CA), we identify practices that further the PWA's participation in the interaction while planning afternoon activities together with his wife. The PWA contributes to the planning talk by initiating and modifying planning sequences. The spouse supports his participation by aligning with his initiat…
Collaborative storytelling with a person with aphasia - Promoting agency in a multiparty interaction
2021
Introduction: This study explores practices employed by a person with aphasia (PWA) and his wife to organize collaborative storytelling in a multiparty interaction. We identify practices that further the PWA’s agency – his impact on action – while he is telling a story together with his wife. Method: Using conversation analysis (CA), we carried out a case study of a successful storytelling sequence involving a 39-year-old man with anomic aphasia during a conversation with friends. Analysis: The PWA contributed to the storytelling by initiating the story sequence and by producing short but significant utterances in which he provided essential information and displayed epistemic authority. Th…

Prepositions and pronouns in connected discourse of individuals with aphasia
2018
The lexical-grammatical divide has been a widely addressed topic in aphasia. Speech parts are generally classified as either belonging to a lexical or a grammatical category based on the frequency of acquisition of new members in their paradigms (open vs. closed classes), thus neglecting heterogeneity within categories. Such an approach has led to contradictory findings. First, prepositions form closed classes, but are classically taken as lexical items. Pronouns, also belonging to a closed class, are analyzed as grammatical elements. Second, both within the group of prepositions and pronouns, forms with different syntactic and semantic properties co-exist. Following the theoretical notions…
The Selective Impairment of Phonological Processing in Speech Production
2000
We report the naming performance of a patient (DM) with a fluent progressive aphasia who made phonological errors in all language production tasks. The pattern of errors in naming was strikingly clear: DM made very many phonological errors that resulted almost always in nonword responses. The complete absence of semantic errors and the very low ratio of formal errors relative to nonword errors (1.6:30.3) in DM's performance are discussed in the context of recent claims about the nature of naming deficits in fluent aphasics. We argue that DM's performance makes highly improbable the claim that fluent aphasia results from global lesions affecting all levels of the lexical access system equall…
