Investigating the Neural Activity Behind Rhythm-Keeping : An Exploratory Mass Univariate Study

Sammanfattning: Many of the skills that are considered noteworthy in our societies are either acquired through training and dedication or granted to those lucky enough to have the right genetics and environment. But one skill that is often overlooked is the ability to keep rhythm. This skill is both remarkable in temporal accuracy and common. And although rhythm-keeping is a common cognitive skill, not much is known about the neural correlates of rhythm-keeping. The aim of the current exploratory study was to investigate the electrophysiological correlates of rhythm-keeping. In this study, participants were asked to perform a task where they were introduced to a rhythm with both auditory and visual cues to correct themselves after. They were then supposed to keep the rhythm for approximately thirty seconds, even though all stimuli indicating the rhythm were removed after six seconds of performing the task. During the task, electrophysiological data were collected using electroencephalography (EEG). The electrophysiological data and task performance were then analysed using mass univariate analysis, but no significant relationship was found between the electrophysiological data and rhythm-keeping performance. Potential issues underlying these non-significant findings, as well as solutions to address these, will be addressed.
