to investigate whether leading questions bias a persons response or actually alter the memory that is stored
what are the strengths of loftus and palmers study
lab experiment high levels of control , high levels of replicability
independant measures-reduced demand characteristics
quantitative data easy to analyse

ethnocentric- all participants were from washington uni
lab experiment - low ecological validity
protection- participants are watching videos of crash so may cause pyschological harm

the context dependant memory applies for newly learned materials in recall and recogniton task
what are the strengths from grants
independant measures
reduces order effects and demand characteristics
ethics - participants given a debrief
quantitave data - easy to analsyse
what are the weaknesses of grants study
lab experiment- low ecological validity
quantitative- lacks depth and detail
independant measures - larger number of participants needed
