1.1.3 Strengths & Weaknesses (Biological Approach) Flashcards
What is the first step in evaluation?
- State the strength/weakness
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
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 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
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)
Psychosurgery can be used to treat mental illness: • DBS can be used to treat those suffering with depression by applying current that disrupts brain circuitory involved in the disorder
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
Why is weakness 1 (reductionist) a weakness?
- ignores/ doesn’t account for environmental factors that could influence behaviour (e.g. A person could be depressed due to family life, grief, employment)
Give weakness 2 of the biological approach (n):
The biological approach is a nomothetic approach
Explain what it means that the biological approach is a nomothetic approach:
It looks to make generalisations about people and find similarities (universal laws)
Give examples for weakness 2 (nomothetic approach):
- biological studies use few people and assume people’s biological systems are the same - people used are mostly from the U.S and Europe as this is where research takes place - research tends to use males as they are simpler biologically. Hormones affect their behaviour less.
Explain why weakness 2 (nomothetic approach) is a weakness:
- behaviours might not be able to be generalised universally (etics) - lack of cross cultural research (ethnocentric) - beta gender bias
What are etics?
Universal behaviours
What is beta gender bias?
Testing one gender and assuming the other will respond in the same way
