Which is an example of the post-identification feedback effect?

The post-identification feedback effect refers to the phenomenon where a person's confidence in their memory can be significantly altered after they receive feedback about their identification of a suspect or an event, particularly after a line-up or similar identification procedure. In this context, the correct example illustrates how information provided after an identification can influence a person's recollection of the event, leading to distortions in memory.

In this case, a person might remember events that did not actually happen, such as having false memories of attending camp, which could be a result of suggestive feedback or conversations after the identification process. This can contribute to a distorted sense of personal history and can lead individuals to firmly believe in these fabricated memories, showcasing the impact that post-identification feedback can have on an individual's recollection and self-perception.

The other choices reflect different aspects of memory without directly involving the concepts underlying the post-identification feedback effect. They involve memory enhancement through various means, but do not specifically illustrate how feedback following an identification can alter a person’s beliefs about their past experiences.
