Sleep, Dreams, and sleep
disorders cognitive
approach
Crick and Mitchison's reorganizational theory 1986
to keep our memory at top
physical performance or to
improve are memory a
decluttering process must take
place in which the brain will
delete unwanted memories
Stickgold 2009
sleeping improves every type of memory (sensory,short,long)
Funtion of sleep may
support the
formation of the long
term memory
Weaknesses
computer
analogy
therefore totally
ignores the
social and
emotional
influences
tends to lack ecological validity
Sleeping has an impact on our cognitive processing
this can be
seen by
people who
dont get
enough sleep
have a
decreased
recall ability
Computer analogy
suggests brain
works like
computer by
encoding the
information the
stores it for
later use then
outputs the
needed
information for
the approate
situation
therefore totally ignores emotion
Schemas Bartlett 1932
Sleep may
help the
assimilation of
newly formed
information
Irrational thoughts/ beliefs are thought to cause sleep disorders like insomnia
if drug treatment is
not wanted or unable
to help. psychiatrists
use CBT (cogitive
behavioural therapy)
which is a non drug
treatment that trys to
sort mental disorders
by fighting the
irrational
thoughts/ideas the
person has by the
psycologist giving
ideas and coping
mechisisms for the
person to use
links to Ellis ABC modal 1962
an activating agent like a spider
leads to either a rational belief, for
example, the spider is harmless or it
can have an irrational belief, for
example, the spider is dangerous
and these beliefs can lead to two
different consequences: a healthy
response which is to ignore the
spider or you can have an unhealthy
response which is screaming
hysterically
links to Becks cogitive triad 1967
he identified three
mechanisms that he
thought where the
possible reason for
depression
negitive veiw of
the
self,negative
view of the
world and
negitive veiw of
the future
he also called these
Errors in logic aka faulty
information processing
Strenghs.
Majority of research based on highly controlled lab experimets therefore lots of quantatative data on the subject
