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...

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.

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.

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...

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...
