Acceptance and Confidence of Central and Peripheral Misinformation

We examined the memory for central and peripheral information concerning a crime and the acceptance of false information. We also studied eyewitnesses' confidence in their memory. Participants were shown a video depicting a bank robbery and a questionnaire was used to introduce false central and peripheral information. The next day the participants completed a recognition task in which they rated the confidence of their responses. Performance was better for central information and participants registered more false alarms for peripheral contents. The cognitive system's limited attentional capacity and the greater information capacity of central elements may facilitate processing the more important information. The presentation of misinformation seriously impaired eyewitness memory by prompting a more lenient response criterion. Participants were more confident with central than with peripheral information. Eyewitness memory is easily distorted in peripheral aspects but it is more difficult to make mistakes with central information. However, when false information is introduced, errors in central information can be accompanied by high confidence, thus rendering them credible and legally serious.
