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…
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 …
Syntax and conversation in aphasia. A strategic restrictive use of Spanish and Catalan connector QUE by aphasic speakers.
2009
Oral conversational data are deemed to be a relevant empirical source when it comes to formulating and supporting hypotheses about cognitive processes involved in aphasic linguistic production. With this assumption in mind, free conversational uses of the Spanish and Catalan connector QUE by fluent and non-fluent aphasic speakers are examined by contrasting them with normal speakers' (i.e. conversational partners') productions. Strictly ungrammatical uses in aphasic speakers are practically non-existent in free conversation. Nevertheless, this data permits one to characterize the aphasic production of the morpheme QUE as restrictive--to different degrees--with respect to normal production. …
Assessing natural metalinguistic skills in people with Alzheimer’s disease and frontotemporal dementia
2019
Abstract Objective The aim of this paper is to assess whether the use of natural metalinguistic skills can be used to differentiate linguistic-communicative profiles of people with dementia (Alzheimer’s disease and frontotemporal dementia in the behavioural and primary progressive aphasia variants) in the earliest stages of the disease. Method A sample of 180 people was selected. Sixty had Alzheimer’s disease, 20 had frontotemporal dementia of the behavioural variant, and 40 had frontotemporal dementia of the primary progressive aphasia variant (20 had non-fluent primary progressive aphasia and 20 had semantic dementia). The control group was composed of 60 healthy people with ages, gender,…

An aphasia research agenda–a consensus statement from the collaboration of aphasia trialists
2021
Coordination of international aphasia research would minimise duplication of effort, support synergistic international activities across languages and multidisciplinary perspectives, and promote high-quality conduct and reporting of aphasia research, thereby increasing the relevance, transparency, and implementation of findings. The Collaboration of Aphasia Trialists (CATs) sought to develop an aphasia research agenda to direct future research activities, based on priorities shared by people with aphasia, family members, and healthcare professionals. Our established international research network spanning 33 countries contributed to this activity. Research literature reporting the prioritie…
