Our Research

The primary goal of the group is to investigate the facilitatory effects of predictive cues in comprehension and its underlying processes. Focusing on rhythmic, formal, and emotional cues in communicative signals, we aim to identify factors that modulate the extraction of cues and thus the resulting predictions. Furthermore, we examine the functional and neuroanatomical links between specialized processing systems (language, learning, emotion, and sensorimotor) with respect to different types of predictive cues such as rhythm and emotion. In order to address these matters, behavioral, electrophysiological and brain imaging measures are employed in healthy and patient populations. Our research is based on an integrated perspective that comprises the interaction of cortical, basal ganglia and cerebellar circuitries.

Learning & Re-learning

How does our ability to adapt to changes in the environment ultimately lead us to acquire new knowledge about the environment and optimize our behavior? How can adaptation to external cues additionally support re-learning in cases of cognitive decline in healthy aging or neurological dysfunction? Do we learn better if someone else is guiding us, or are we equally able to learn by ourselves? Using behavioral and neuroimaging techniques (EEG, fMRI), we investigate the link between adaptation to environmental dynamics and the learning and re-learning of those dynamics, as well as the factors that optimize adaptation and hence learning. In our research, we approach these questions from both an individual as well as from an inter-individual point of view.

Adapting to Dynamic Environments

We are interested in the ability to successfully navigate through, and interact with, an ever-changing dynamic environment. We investigate the mechanisms which allow adequate timing and adaptation to the rate and rhythm of events in the environment using behavioural and neuroimaging techniques. As inadequate timing factors into the neurofunctional profile of different patient populations, we use our findings to develop strategies for compensation.

Voice Adaptation and Vocal Learning

According to control theory, internal models play a decisive role in how our brain operates at an optimum level. By extracting sensory information from the environment and integrating it across domains, the brain is constantly updating its modus operandi, thereby using sensory resources as efficiently as possible. An essential prerequisite for this efficiency is the ability to form sensory predictions, which entails a repeatedly encountered stimulus to become less salient and thus, more predictable. With the extension of a well-established somatosensory model into the auditory domain, our focus lies on elucidating individual differences in auditory sensory prediction by using behavioral and neuroimaging techniques (EEG & fMRI).
