Sleep, Dreams, and sleep disorders cognitive approach

Sleep, Dreams, and sleep disorders cognitive approach

1. 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

2. Stickgold 2009

   • sleeping improves every type of memory (sensory,short,long)

3. 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

4. Sleeping has an impact on our cognitive processing

   • this can be seen by people who dont get enough sleep have a decreased recall ability

5. 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

6. Schemas Bartlett 1932

   • Sleep may help the assimilation of newly formed information

7. 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

8. Strenghs.

   • Majority of research based on highly controlled lab experimets therefore lots of quantatative data on the subject
