Multi-modal discourse comprehension requires speakers to combine information from speech and gestures. To date, little research has addressed the cognitive resources that underlie these processes. Here we used a dual-task paradigm to test the relative importance of verbal and visuospatial working memory in speech-gesture comprehension. Healthy,…

In this study we investigated whether the beneficial effect of adding illustrations to text can be explained by the fact that illustrations facilitate analogous mental representation construction from text in visuospatial working memory. For this the secondary task paradigm was used. It was expected that the secondary task interfered only with…

When speakers coordinate with one another, they have available a range of alternatives for conceptualizing and describing spatial relationships. To understand the features of successful communication in collaborative spatial tasks, it is important to identify factors that shape speakers' linguistic choices and evaluate them in relation to task…

Research on cognitive modeling of information search and Web navigation emphasizes the importance of "information scent" (the relevance of semantic cues such as link labels and headings to a reader's goal; Pirolli & Card, 1999). This article shows that not only semantic but also structural knowledge is involved in navigating the Web…
