3.1 Monoamines are a group of neruotransmitters which includes serotonin, norepinephrine and
dopamine. Serotonins role is to regualte other neurotransmitters. Without regulation, erratic brain
functioning and thinking patterns occur. Low levels of serotonin can produce low levels & another
neurotransmitter, norepinephrine. Some anti depressants can be used to increase levels of
norepinephrine. Ithers used to increases levels of another neurotransmitter, dopamine. The ideas
ofor treatment is that, drug is matched to the symptoms of depresssion. Whichever symptom is

4 COGNITIVE MODEL OF DEPRESSSION
4.1 In 1960's Beck developed cognitive model of depression. Considering 3 aspects of
thinking. He looked at cognitice errors that people make about themselves, at faulty
thought patterns & schemata. Seligman out forwards a similar theory when he suggested
that depresssion is a form of learned helpnessness. 1:COGNITIVE TRIAD - negative views
of self, wor and future. 2 COGNITIVE ERRORS - faulty thinking, negative and unrealistic
ideas. 3 SCHEMATA - patterns of thought and beliefs (unhelpful). Cognitive triad found in
people with depression involves the person having negative thoughts about themselves,
about the world and the future. Genetic factors and early experiences affect thinking and
schemata are built up from interactions and these beliefs set assumptions about the world.
