- Evaluation of Godden and Baddeley
- Demand Characteristics
- Aware they were taking part in an experiment
- behave unnaturally
- Decreased Validity
- behave unnaturally
- Aware they were taking part in an experiment
- Ecological Validity
- wouldn't normally recall isolated words
- not real life task
- Realistic environment for divers
- real life setting/task
- wouldn't normally recall isolated words
- Reliability
- participant variables and weather conditions can not be controlled
- less reliable, less likely to get same results if repeated
- stansardised procedure - e.g. amount of words
- more reliable, study done again with similar results
- participant variables and weather conditions can not be controlled
- Generalisability
- small sample + only divers
- not representative
- small sample + only divers
- Application
- helps divers on north sea oil rigs recall information they have learnt when on sea bed.
- Eye witness testimony
- Police use reconstructions
- give state and context cues to improve recall
- Police use reconstructions
- Repeated Measure Design
- no participant variables
- increases validity
- no participant variables
- Participants who didnt move environment...
- longer to rehearse infomration
- lower validity
- longer to rehearse infomration
- Internal Validity
- Extraneous Variables controlled e.g. gaps between words
- conclude that it was the IV affecting the DV
- Extraneous Variables controlled e.g. gaps between words
- Demand Characteristics
