Title Audiovisual enhancement of cortical speech processing
Description

The Biological Psychology lab offers a master’s thesis on the audiovisual integration of speech. The goal of this project is to investigate how visual speech cues affect the neural representation of speech along different stages of the auditory processing network.

Audiovisual integration of speech is often linked to “high-level” processing of information in heteromodal association cortices (such as posterior STS). To which extent neural responses in early auditory sensory regions are also modulated by visual cues is still rather unclear. In this study, we use functional MRI and continuous natural stimulation (i.e., video clips of talkers) to investigate in detail which subdivisions of auditory cortex are modulated by visual input and show enhanced stimulus-related responses to audiovisual vs. auditory speech in noise.

The fMRI data will be analyzed using an inter-subject correlation approach that allows isolating spatiotemporal cortical patterns of stimulus-stimulus activity. This approach is established in the lab and analysis scrips are available. However, methodological interest in fMRI data analysis and a good command of Matlab are advantageous.
