Investigating the utility of cognitive interview mnemonics among non-native English speakers

Best practice eyewitness interviewing mnemonics have not been tested with linguistically diverse samples. Cognitively complex mnemonics may overload non-native speakers’ cognitive resources, which are already engaged in speaking a non-native language. Social facilitation mnemonics may help non-native speakers, who might be hesitant to report details. The current study tested the reverse order mnemonic (cognitively complex) and a set of introductory instructions (social facilitation) compared to control interviews among native and non-native English speakers. Native speakers provided more details than nonnative speakers, particularly in the control interview condition. Both the reverse order and control conditions elicited newly generated details because of repeated questioning. Accuracy rates were comparable across language and interview conditions. Future research should develop an interviewing protocol that is sensitive to the challenges faced by nonnative speakers.
