Rhythm perception and Polyrhythms: Continuous change in rhythm over time

Rhythm perception and Polyrhythms: Continuous change in rhythm over time

Abstract

Participants in this study were recruited primarily from the psychology department of the University of Oslo (UiO). For this pilot study, sixteen participants were tasked with a rhythmic tapping task during an fMRI scan, in which they were instructed to listen for a presented rhythm and follow the pattern they heard by pressing a button on a provided keypad. During this experiment the participants were exposed to auditory stimuli in a block pattern, each block consisting of between one to four distinct rhythmic patterns of varying complexity lasting 30 seconds. Data was collected by this student from the intervention center of Universitetssykehus Rikshospitalet. Six participants were excluded from the data pool following data collection due to artifacts or errors during data collection. This pilot project is meant to assess the validity of the task used here for a larger scale study. Results were largely statistically insignificant, but patterns of activation across conditions were consistent with previous literature, suggesting the task used in this pilot may be valid for a full study. Significant results indicated that lower levels of rhythmic complexity are linked to lower level of activation in motor areas such as the cerebellum and increased activity in auditory regions such as the superior temporal gyrus.
