The study will usually be conducted in a laboratory setting (rather than outside), where undergraduate (rather than real eyewitnesses) are exposed to video taped scenarios (rather than real events). A field of psychology that examines issues arising out of the interaction between human behaviour and the law, legal system, or legal process.
