Hanna is interested in how predictions shape auditory perception and cognition. She obtained her BSc, MSc, and PhD in psychology from Leipzig University and the International Max Planck Research School on Neuroscience of Communication (IMPRS NeuroCom) at the Max Planck Institute for Human Cognitive and Brain Sciences, investigating how listeners form memories of novel sound patterns. Before joining the lab, she spent a year as a postdoc at the University of Tokyo in Japan, researching statistical learning in individuals with and without dyslexia. At Ruhr University Bochum, she is using 7T fMRI to investigate predictive processing during speech perception.
