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...

Balanced bilinguals favor lexical processing in their opaque language and conversion system in their shallow language

Buetler, Karin A. ; Rodríguez, Diego de León ; Laganaro, Marina ; Müri, René ; Nyffeler, Thomas ; Spierer, Lucas ; Annoni, Jean-Marie

In: Brain and Language, 2015, vol. 150, p. 166–176

Referred to as orthographic depth, the degree of consistency of grapheme/phoneme correspondences varies across languages from high in shallow orthographies to low in deep orthographies. The present study investigates the impact of orthographic depth on reading route by analyzing evoked potentials to words in a deep (French) and shallow (German) language presented to highly proficient bilinguals....

Cue recognition and integration – eye tracking evidence of processing differences in sentence comprehension in aphasia

Schumacher, Rahel ; Cazzoli, Dario ; Eggenberger, Noëmi ; Preisig, Basil ; Nef, Tobias ; Nyffeler, Thomas ; Gutbrod, Klemens ; Annoni, Jean-Marie ; Müri, René M.

In: PLoS ONE, 2015, vol. 10, no. 11, p. e0142853

We aimed at further elucidating whether aphasic patients’ difficulties in understanding non-canonical sentence structures, such as Passive or Object-Verb-Subject sentences, can be attributed to impaired morphosyntactic cue recognition, and to problems in integrating competing interpretations.Methods: A sentence-picture matching task with canonical and non-canonical spoken sentences was...

Perception of co-speech gestures in aphasic patients: A visual exploration study during the observation of dyadic conversations

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

In: Cortex, 2015, vol. 64, p. 157–168

Co-speech gestures are part of nonverbal communication during conversations. They either support the verbal message or provide the interlocutor with additional information. Furthermore, they prompt as nonverbal cues the cooperative process of turn taking. In the present study, we investigated the influence of co-speech gestures on the perception of dyadic dialogue in aphasic patients. In...
