摘要

In the current experiment, we examined the effectiveness of the Cognitive Interview (CI) on eyewitness testimony concerning a traffic accident using two recall moments (immediately versus one-week delay). Furthermore, we assessed whether the CI method could protect against the negative effect of suggestive questions. A laboratory experiment was conducted among Indonesian young adult car drivers and motorcyclists (N = 172) that never had any traffic accident experience. Participants were interviewed, either with a CI or a Standard Interview (SI), after watching a video about a traffic accident. Half of the participants were interviewed immediately after watching the video, while the other half were interviewed a week after watching the video. In the final interview phase, all participants were given suggestive questions to examine whether the CI would protect from these suggestions. The CI method led to the reporting of more correct details, particularly the event-related, central, and peripheral details, compared to the SI method. Furthermore, in the delay condition, participants recalled more false details than participants in the immediate condition. Moreover, the CI did not protect from the effects of suggestion. This experiment provides additional empirical support for the efficacy of the CI in the context of traffic accidents, particularly in an Asian setting.
