Research examining the impact of sleep in school-age children suggests that even mild sleep loss produces marked deficits in their cognitive development and functioning. Sleep restriction can alter children's initial stages of speech perception, which could contribute to disruptions in cognitive and linguistic functioning -- skills necessary for reading and language development and comprehension, according to recent research.
Rachel Waford, of the University of Louisville, who authored the study, recorded event-related potentials, as a measure of neurocognitive development, from 32 children six-to-seven years of age while they listened to the following computer-generated speech syllables: /ba/, /da/ and /ga/.
The results showed that those children not getting an adequate amount of sleep were more likely to phonetically code incorrectly different speech sounds.
"Our research has shown that even minor sleep loss of one hour less per night for seven nights contributes to disruptions in neurocognitive functioning," said Waford. "The early school years are crucial windows that determine future learning. Therefore, it is imperative that children in this age range are well-rested to prepare for the demands of the school day."
Experts recommend that children in pre-school sleep between 11-13 hours a night, and school-aged children between 10-11 hours of sleep a night.
