Interlocutors typically link their utterances to the discourse environment and enrich communication by linguistic (e.g., information packaging) and extra-linguistic (e.g., eye gaze, gestures) means to optimize information transfer. Psycholinguistic studies underline that ‒for meaning computation‒ listeners profit from linguistic and visual cues that draw their focus of attention to salient information. This dissertation is the first work that examines how linguistic compared to visual salience cues influence sentence comprehension using the very same experimental paradigms and materials, that is, German subject-before-object (SO) and object-before-subject (OS) sentences, across the two cue modalities. Linguistic salience was induced by indicating a referent as the aboutness topic. Visual salience was induced by implicit (i.e., unconscious) or explicit (i.e., shared) manipulations of listeners’ attention to a depicted referent.
In Study 1, a selective, facilitative impact of linguistic salience on the context-sensitive OS word order was found using offline comprehensibility judgments. More precisely, during online sentence processing, this impact was characterized by a reduced sentence-initial Late positivity which reflects reduced processing costs for updating the current mental representation of discourse. This facilitative impact of linguistic salience was not replicated by means of an implicit visual cue (Study 2) shown to modulate word order preferences during sentence production. However, a gaze shift to a depicted referent as an indicator of shared attention eased sentence-initial processing similar to linguistic salience as revealed by reduced reading times (Study 3). Yet, this cue did not modulate the strong subject-antecedent preference during later pronoun resolution like linguistic salience. Taken together, these findings suggest a significant impact of linguistic and visual salience cues on sentence comprehension, which substantiates that both the information delivered via language and via the visual environment is integrated into the mental representation of the discourse; but, the way how salience is induced is crucial to its impact.
Sensitivity to salience
(2018)
Sentence comprehension is optimised by indicating entities as salient through linguistic (i.e., information-structural) or visual means. We compare how salience of a depicted referent due to a linguistic (i.e., topic status) or visual cue (i.e., a virtual person’s gaze shift) modulates sentence comprehension in German. We investigated processing of sentences with varying word order and pronoun resolution by means of self-paced reading and an antecedent choice task, respectively. Our results show that linguistic as well as visual salience cues immediately speeded up reading times of sentences mentioning the salient referent first. In contrast, for pronoun resolution, linguistic and visual cues modulated antecedent choice preferences less congruently. In sum, our findings speak in favour of a significant impact of linguistic and visual salience cues on sentence comprehension, substantiating that salient information delivered via language as well as the visual environment is integrated in the current mental representation of the discourse.
