Ethical issues.

if the studies are realistic then children can't be used as participants as they would be harmed psychologically. If they studies are ethical then they are too low in ecological validity to be in any use.
Low ecological validity such as Loftus and Burn's video tapes has no ethical issues but it is unrealistic. If the study is high in ecological validity it will have ethical issues as they'll be unaware that its an experiment and be in danger of psychological harm
If a study like Loftus has high ecological validity to keep participants safe, then there will be ethical issues such as the participants hearing an argument and witnessing a man with a bloody knife with no warning prior to it. This could be distressing and cause psychological damage. However if they were warned beforehand to stop any ethical issues this would vastly reduce ecological validity to the extent of the research not being useful anymore.
