Probing auditory perceptual constraints across individuals

Natural sounds contain rich temporal structure over various timescales. Previous research suggests neuronal oscillations to be one critical mechanism for processing the temporal structure of sound, with a particular sensitivity in the delta (0.5-3 Hz), theta (4-8 Hz), and low gamma ranges (25-80 Hz), compared to the alpha range (8-12 Hz). Thereby neuronal oscillations might constrain auditory perception by affecting the temporal resolution of auditory perception. How well a complex sound structure is encoded depends on the temporal resolution, i.e. the ability to differentiate different timescales. In this project, in a psychoacoustics paradigm, we investigate the temporal resolution across a range of stimulus rates, particularly we focus on individual differences in these processes.
