  • Biological Approach
    • Assumptions
      • Different parts of the brain explain behaviour
      • Hormones Explain Behaviour
    • Selye's GAS Model
      • GAS: General Adaption Syndrome
        • Stage one: Alarm Reaction
          • The stressor is recognized and the response is being made. Initial symptoms take place eg. Adrenaline rush, sweaty palms.
        • Stage two: Resistance
          • Body starts to adapt to the environment.  The body appears to be coping but mentally, things are deteriorating.
        • Stage three: Exhaustion
          • The body system malfunctions and the initial symptoms reappear- If it reaches stage four then they die.
    • Selye's experiment on rats
      • Concluded that noxious agents cause stress.
      • Rats do not react to stress the same way as humans because rats all possess one internal stressor mechanism
    • Strengths of Biological Approach
      • Scientific: Selye rats experiment- Exposing them to various noxious agents, studied them and found out they produced similar responses. Scientific because it was repeated several times
      • Determinist: Neurotransmitter dopamine has been associated with the mental disorder schizophrenia. Determinist because causal relationships can be identified to help produce better results
    • Weaknesses of Biological Approach
      • Nature vs Nurture argument: Treatment to mental illness, more concerned with adjusting the systems in the body rather than concentrating on how the patient feels. Weakness because other factors such as emotions could play a part in getting the illness
      • Ignores individual differences: Psychiatric drugs do not effect all people in the same way. Antipsychotic drugs do not have severe side effects. By ignoring individual differences, it may inadvertently make the disorder worse through poor treatment
