Cortical processing of speech in high-school students with different sleeping habits

Abstract

Sleep plays a critical role on cognitive function especially in the developing brain. However, sleep duration and sleep timing are marked by individual differences. It is currently unknown whether and how sleep habits modulate speech perception in the developing brain. This study examined the correlation between sleep duration and brain responses to speech contrast in high-schoolers. A passive-listening oddball paradigm was used to deliver the speech contrast, and electroencephalogram (EEG)/Event-related potentials (ERPs) were used to collect cortical responses. Preliminary results indicated that there is a negative correlation between mismatch negativity responses and sleep duration in high-schoolers. The implication of the study will be discussed.
