Abstract | Introduction: This study examined the sleep-dependent memory consolidation
hypothesis through napping in adolescents in their naturalistic
living environment. Previous controlled experimental studies suggested
that a short nap could help support memory consolidation and learning
in normally sleeping adults. This study attempted to extend previous
findings by demonstrating memory consolidation effects of napping
with multiple memory tasks in adolescents who commonly have inadequate
sleep.
Methods: Forty healthy adolescents, aged 15-19 were recruited at a full
time boarding English-speaking high school in Hong Kong. Volunteering
participants were matched in pairs on age, sex and sleepiness, using
the Cleveland Adolescent Sleepiness Questionnaire. They were then
randomly assigned to either the “nap” (n=21) or the “no-nap” condition
(n=19). Three verbal learning and recall tasks - prose recall, word pair
associates, and word list learning were adopted. Task stimuli were presented
to all participants at around 2.00pm on the testing day. The nap
group was then instructed to take a nap at their own dormitory room
between 3.15pm and 4.15pm while the no-nap group was instructed to
stay awake as usual. Re-testing of recall and recognition tasks and learning
of a new word list was scheduled at 5.15pm.
Results: The nap group was significantly better at recalling previously
learnt proses [F (1,36) = 9.11, p= .005, η2= .202] and word pairs [F
(1,36)=5.80, p =.021, η2=.139]. These effects were not associated with
self-reported sleep duration in the preceding seven nights and daytime
sleepiness. The nap group also performed better in learning a new word
list after napping than the no-nap group [F (1,37) = 6.905, p = .012,
η2=.157].
Conclusion: Our results suggested that a short nap can be of benefit to
students of diverse sleep status. Planned, polyphasic sleep complementary
to good sleep hygiene may be advisable to help adolescents cope
with increasing cognitive demands in modern societies. |
