Zusammenfassung (Englisch)

By means of combining eye-tracking and fMRI, the present study aimed to investigate aspects of higher linguistic processing during natural reading which were formerly hard to assess with traditional paradigms. Specifically, we investigated the haemodynamic effects of incremental sentence comprehension as operationalised by word position and its relation to context-based word-level effects of lexical predictability. We observed that an increasing amount of words being processed was associated with an increase in activation in the left posterior middle temporal and angular gyri. At the same time, left occipito-temporal regions showed a decrease in activation with increasing word position. Region of interest (ROI) analyses revealed differential effects of word position and predictability within dissociable parts of the semantic network showing that it is expedient to consider these effects conjointly.
