- Eye Witness Testimony - Evaluation of Research
- - Research mainly lab based: lacks ecological validity --> emotional responses will not represent real life
- + Reliability, more control of extraneous variables.. can replicate w/ similar results
- E.g. Loftus and Palmer used a standardised procedure of pps watching the same video clips
- + Cognitive interview developed from the research
- Involves: 1. recalling events from different perspectives
- 2. remembering event in different order
- 3. re-instating context and mood
- 4. recalling every detail
- + Research allows investigation which would be unethical to do in real life
- - Demand Characteristics; pps know they are in a study
- If students are used they may work out the aim or try harder in the tests as they are used to being tested
- Also affects generalisability
- If students are used they may work out the aim or try harder in the tests as they are used to being tested
