What: The predictive brain: from sensation to comprehension in communication


Human communication necessitates coherent and temporal integration of verbal (formal aspects of speech and language) and non-verbal (e.g. vocal, facial, gestural, body expressions) information. Such a complex process requires the dynamic formation of percepts that are updated in a given situational context and concurrently by an individual’s fluctuating internal state. However, the dynamic formation of percepts is costly, prone to conflict, and individual processing resources are limited. Therefore, mechanisms to efficiently allocate attention and to predict future input are necessary to reduce processing costs and conflict. The core goals of the current research are (1) to specify the impact of prediction on sensory, multisensory, and cognitive processes exemplified in human communication, (2) to define the neural networks supporting these processes, and to understand the consequences of (3) altered input into the communicative system (i.e. bilingualism) and (4) system breakdowns on mechanisms to predict future input in communication. I will present behavioural, electrophysiological (event-related potentials and time-frequency) and functional magnetic resonance imaging data on this research and will give an outlook on future work centred on the predictive communicative brain in a number of populations (lifespan, clinical, bilingual).
