- Low levels of it can cause depression and reduce those functions

- Evaluation
- Twin Studies show there isn't 100% concordance so therefore there must be environmental factors
- With nuerotransmitters and hormones its hard to establish the cause and effect
- Reductionist to elimainate complex behaviours down the cells and chemicals
- Deterministic. Can have negative implications on the patients treatment if they think its out of their control they have no free will and will effect recovery
- Diathesis stress model - may have it but may not experience life events so dont develop the disorder
- Hormones
- Psychodynamic explanations
- Experience of rejection and desertion during the oral stage of development - regression
- Anger becomes self directed and experience guilt
- This self punishment is called Introjection of hostility
- Bolby's attachment theory - poor attachment to parents so seeks approval to compensate for rejection
- The role of the personality - superego feels guilty in the depressive stage and ego in the manic
- Evaluation
- unscientific as all in early childhood which we cant directly test
- early theories have led to successful treatments
- Cognitive explanations
- they think in negative self defeating ways
- Informational processing
- Overgeneralisation - think if one things bad then everything is bad
- Selective perception - only viewing the bad
- Magnification - blowing things out of proportion
- Becks Cognitive Traid
- The self, Future and experiences
