Multimodal communication in aphasia: perception and production of co-speech gestures during face-to-face conversation

Preisig, Basil C. ; Eggenberger, Noëmi ; Cazzoli, Dario ; Nyffeler, Thomas ; Gutbrod, Klemens ; Annoni, Jean-Marie ; Meichtry, Jurka R. ; Nef, Tobias ; Müri, René M.

The role of nonverbal communication in patients with post-stroke language impairment (aphasia) is not yet fully understood. This study investigated how aphasic patients perceive and produce co-speech gestures during face-to-face interaction, and whether distinct brain lesions would predict the frequency of spontaneous co-speech gesturing. For this purpose, we recorded samples of conversations...

Eye gaze behavior at turn transition: how aphasic patients process speakers’ turns during video observation

Preisig, Basil C. ; Eggenberger, Noëmi ; Zito, Giuseppe ; Vanbellingen, Tim ; Schumacher, Rahel ; Hopfner, Simone ; Gutbrod, Klemens ; Nyffeler, Thomas ; Cazzoli, Dario ; Annoni, Jean-Marie ; Bohlhalter, Stephan ; Müri, René M.

The human turn-taking system regulates the smooth and precise exchange of speaking turns during face-to-face interaction. Recent studies investigated the processing of ongoing turns during conversation by measuring the eye movements of noninvolved observers. The findings suggest that humans shift their gaze in anticipation to the next speaker before the start of the next turn. Moreover, there...

Screening for language disorders in stroke: german validation of the language screening test (last)

Koenig-Bruhin, M. ; Vanbellingen, Tim ; Schumacher, Rahel ; Pflugshaupt, T. ; Annoni, Jean-Marie ; Müri, René M. ; Bohlhalter, Stephan ; Nyffeler, Thomas

In: Cerebrovascular Diseases Extra, 2016, vol. 6, no. 1, p. 27–31

Background: Screening of aphasia in acute stroke is crucial for directing patients to early language therapy. The Language Screening Test (LAST), originally developed in French, is a validated language screening test that allows detection of a language deficit within a few minutes. The aim of the present study was to develop and validate two parallel German versions of the LAST. Methods: The...

The modulation of reading strategies by language opacity in early bilinguals: an eye movement study

De León Rodríguez, Diego ; Buetler, C,, Karin A. ; Eggenberger, Noëmi ; Preisig, Basil C. ; Schumacher, Rahel ; Laganaro, Marina ; Nyffeler, Thomas ; Annoni, Jean-Marie ; Müri, René M.

In: Bilingualism: Language and Cognition, 2016, vol. 19, no. 3, p. 567–577

Converging evidences from eye movement experiments indicate that linguistic contexts influence reading strategies. However, the question of whether different linguistic contexts modulate eye movements during reading in the same bilingual individuals remains unresolved. We examined reading strategies in a transparent (German) and an opaque (French) language of early, highly proficient...

Comprehension of co-speech gestures in aphasic patients: an eye movement study

Eggenberger, Noëmi ; Preisig, Basil C. ; Schumacher, Rahel ; Hopfner, Simone ; Vanbellingen, Tim ; Nyffeler, Thomas ; Gutbrod, Klemens ; Annoni, Jean-Marie ; Bohlhalter, Stephan ; Cazzoli, Dario ; Müri, René M.

In: PLOS ONE, 2016, vol. 11, no. 1, p. e0146583

Co-speech gestures are omnipresent and a crucial element of human interaction by facilitating language comprehension. However, it is unclear whether gestures also support language comprehension in aphasic patients. Using visual exploration behavior analysis, the present study aimed to investigate the influence of congruence between speech and co-speech gestures on comprehension in terms of...
