- Features of Science
- Falsifiability
- Theory cannot be considered scientific unless it admits the pos. of being untrue
- Objectivity
- Research based on hyps + theories NOT opinion
- Researcher must keep critical distance from research
- Lab Exp. is most objective - controls EVs (bias) and procedures are standardised
- Product objectivity
- Exp.s + theories est. acc. rep.s of external world - not affected by desires/ goals/ capabilitie/ experience
- Process objectivity
- methods not dependent on soc./eth. values or individual bias of sci.
- Replicability
- Work should be checked - inv.s need to be repeated to establish reliability
- Repeated w/ same findings = high int. validity + high replicability
- Exp.s should be published. Inc. no. of pts, standardised procedure, place of study and raw data + analysis
- Empirical Method
- Belief of sci. community, knowledge based on evidence from direct obs. / measurement
- Strategies to ensure empiricism
- More than one researcher
- Repeated measures design
- w/holding true aim from pts
- Theory Construction
- General laws/ principles that have the ability to explain behav.
- Research cycle
- Hypothesis Testing
- Prediction derived from a theory. Can easily be tested (operationalised)
- Deduction - deriving a new hypothesis from an existing theory
- Falsifiability
- 1) Identify problem
- 2) Develop hypothesis
- 3) Test hypothesis
- 4) Develop theory
- 5) Modify + repeat
- 6) Modify theory
