Scan Patterns on Visual Scenes predict Sentence Production


A range of cognitive modalities are involved in everyday tasks, which raises the question to which extend these modalities are coordinated. In this paper, we focus on two particular aspects of this coordination: linguistic structure and visual attention during sentence production, based on the hypothesis that similar scan patterns are associated with similar sentences. We tested this hypothesis using a dataset from an eye-tracking experiment in which participants had to describe photo-realistic scenes. We paired each sentence produced with the corresponding scan pattern, and computed a range of similarity measures for both modalities. Correlation and mixed model analyses confirmed that trials involving similar scan patterns also involve similar sentences productions. This was true for all pairs of linguistic and scan pattern similarity measures we investigated. The result holds both before and during sentence production, and for within-scene and between-scene analyses.
