One weakness of lab experiments when researching effects of anxiety on EWT is ethical issues. It would be unethical to induce the extreme levels of anxiety people feel whilst witnessing a crime take place. This is a weakness as it doesn't allow for a completely accurate replication of real life events to fully study the affects of anxiety on EWT.
What is a weakness of lab experiments?
Participants may display demand characteristics. This is a weakness as participants could be changing their answers as a result of guessing the aims of the experiment, therefore results may not be able to be accounted for.
What is a strength of natural experiments in studying affects of anxiety on EWT?
It eliminates the artificial environment created in lab experiments, as it carries out research in a natural way that makes it seem real. This is a strength as the results could be generalised as they may be more accurate to a real life scenario.
