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.
