Difficult
to study because of
individual
differences
Tucker
found big differences in duration of stages
3
and
4
between participants
This was in a
lab
, which suggests there are
biological differences
(not just situational, as controlled setting)
Outside a lab, the situation may
contribute
to sleep cycle
Sleep cycle hard to investigate in lab - participants have to be attached to
monitors
Sleep that takes place may not be reflective of sleep without the
distracting
monitors
Conclusions drawn may lack
validity
, as the research they are based on may lack validity (
ecological
in this case)
Gives us an improved understanding of how the
sleep wave cycle
changes as people
age
Growth hormone
is produced during
sleep
, therefore older people sleep less
This explains
reduced alertness
in old age
This info can be used to introduce strategies to help people
sleep
more when
older
