Research Methods A2 L5 - 8 Flashcards
Science:
Systematic and controlled approach to creating knowledge that we can rely on to predict and control the world
Give 3 factors that determine whether psychology is a science:
- Sample is large and representative
- Key words are operationalised
- Confounding variables have been identified and accounted for
Empirical method:
- A method of gaining knowledge, which relies on direct observation/testing
- Can help separate unfounded beliefs from real truth
Paradigm:
Shared set of assumptions and agreed methods that are found within scientific disciplines
What did Kuhn (1962) say about paradigms and paradigm shifts?
- Paradigms are what distinguishes scientific and non-scientific disciplines eg pre-sciences v natural sciences
- Paradigm shift is when the results of a scientific revolution occurs
What are the 2 stages of paradigm shifts?
1) A theory remains dominant in a scientific discipline. Some researchers question this. Counter evidence accumulates and gains popularity. Present paradigm is overthrown
2) An established science makes rapid progress and a scientific revolution occurs
Give one example of a paradigm shift:
- Copernicus in 16th century
- People thought Earth was at centre of universe but he found that sun was at centre
- This is a paradigm shift
Objectivity:
- Approaching facts in a way that is unaffected by beliefs, opinions, feelings or expectations
- The basis of the empirical method
Replicability:
Extent to which findings of research can be repeated in different contexts and circumstances
4 purposes of replicability:
1) Guards against scientific fraud
2) Researchers can check if the results gained were a ‘one-off’
3) Shows findings are reliable
4) Shows findings are valid
Falsifiability by who:
- Notion that scientific theories can potentially be disproved by evidence
- Popper (1934)
What did Popper (1969) say about scientific theories?
Genuine scientific theories should be tested and can also be proven false
Compare pseudoscience and natural sciences:
- Pseudoscience discipline produce theories that cannot be falsified easily
- Natural sciences also cannot usually be proved false because they are strong
How are theories constructed?
- Via hypothesis testing and re-testing
- Based on results of a range of work
Give 4 stages of deductive reasoning:
1) Propose a theory
2) Develop a hypothesis
3) Test this theory
4) Draw conclusions
