1.1.3 Strengths & Weaknesses (Biological Approach) Flashcards
What is the second step of evaluation?
- Give examples to further explain the strengths and weaknesses
What is the third step in evaluation?
- End with a clear explanation as to why it is a strength/weakness
Give strength one of the biological approach:
- The biological approach is based in the objective study of observable, measurable factors that affect behaviour
What does objective mean?
It is not influenced by any researcher bias
What does making the approach measurable mean?
Operationalising abstract variables
What does it mean to be observable?
We can see/observe it, you are not reliant on the subjects to report back to gain data
What is the first step in evaluation?
- State the strength/weakness
Give an example for strength one (observable,objective,measurable factors)
The researcher can manipulate the factors and measure the effect on behaviour, so they could measure the effect of drugs on neurotransmitter levels and thus mental illness
• eg. Kahn measured effect of BZs on anxiety in comparison to a placebo group and concluded they are superior in treating anxiety
Explain why ‘the biological approach is based upon the objective study of observable and measurable factors that influence behaviour’ (strength 1) is a strength?
• results can be replicated
• consistent results mean it is reliable
• this reliability means a cause and effect relationship can be established
e.g. BZs reduce anxiety by reducing the action of the hormone adrenaline
Give strength 2 of the biological approach:
• the biological approach has led to many useful and successful applications (real world)
Give an example for strength 2 (useful and successful application)
Drug therapy can be used to treat mental illness:
• anti psychotic medication can be used to treat those suffering with schizophrenia by reducing dopamine levels and thus the positive symptoms of schizophrenia
Why is strength 2 (useful and successful real world applications) a strength?
It allows those suffering with mental illness to function better in society/real life
Give weakness 1 of the biological approach (r):
The biological approach is reductionist
Explain what reductuonist means:
It reduces complex behaviours to a set of simple explanations and focuses on a narrow range of biological factors to explain behaviour
Give some examples for weakness 1 (reductionist):
- Stress is reduced to the action of the hormone adrenaline
- depression is explained in terms of low levels of the neurotransmitter serotonin
