Name one reason why psychologists use the scientific approach
can isolate variables, highly controlled, quantitative, replicable, reliable, use of large samples easier.
What is nativism and empiricism?
Nativism- some things were innate nature or heredity in humans. Empiricism- all knowledge comes from experience
One weakness holism
Great practical difficulty to investigate, Holistic assumes mind not same as body thus tend to ignore huge influence of biology. Holistic explanations tend to be more hypothetical.
List 5 ethical considerations
Deception, Confidentiality, Consent, Observation, Withdraw, Deception
How does a shared environment affect identical twins IQ versus same twins in different environments? What does this suggest?
Shared environment generally results in VERY similar IQ for identical twins in different environments IQ will still be highly correlated. The fact the will not be exactly the same means that environmental factors must play a part in IQ not just genetics. Otherwise identical twins raised together in identical environments should have identical IQ scores.
one weakness of reductionism
Ignores complexity of human behaviour, ignores diathesis stress/interactionism
What is ONE psychological research methods that exemplify the nomothetic approach?
experiments
Define experimenter bias and demand characteristics.
Experimenter bias is when the experimenter affect the results of the study. Demand characteristics is when the participant acts a certain way to help the results.
Name and explain 2 types of determinism
Biological: thoughts and behaviours controlled by brain, genetic, hormones etc. Environmental: thoughts and behaviours are controlled by your surroundings and the rewards and punishments you get.
In Bowlby's research he suggested babies were born with behaviours such as crying and ability to smile what debate does this refer to?
Nature- these were innate behaviours and adaptive in an evolutionary sense to ensure attachment thus survival.
Name one strength holism
Integrate different explanations provide more complete understanding of behaviour, does not ignore complexity, examining behaviour functionally including social reasons for behaviour more useful in providing detail about behaviour.
Explain how the idiographic and nomothetic approaches can come together
Psychologist might use a case study and then develop experiments to further test a phenomenon.
How to reduce researcher bias?
Double blind techniques
Explain why aggression can be both biologically and environmentally determined.
Any of following: Answers may vary-MAOA gene, testosterone, brain injury plus trauma, abuse, family modelling violence in childhood
One strength of reductionism
Can be studied scientifically, Can inform treatments, Easily tested as can be broken into small components
Give an example of idiographic research we have explored in the Year 10 course.
Case studies such as HM, Genie, Romanian Orphans, Robertson and Robertson case studies on disrupted attachment of children separated from parents due to extended hospital stays. Patients with DID-Eva Black/White.
How to reduce demand characteristics?
Use of deception, single/double blind techniques.
