Using the attribute amnesia paradigm to test the automatic memory advantage of person names.

Person names, which hold within them extensive meaning, such as gender and cultural information, play an essential role in our social interaction. The intentional memory advantage of person names has been proved, but whether the automatic memory advantage of them exists remains unclear. In order to explore this question, we used a paradigm called attribute amnesia that allows us to test the automatic memory of person names in a working memory task. In Experiment 1, we adopted a classic attribute amnesia paradigm including 11 pre-surprise trials requiring participants to report the location of the target (person names or animal names) among three distractors and one surprise trial requiring them to unexpectedly report the identity of the target. The results showed that the identity report accuracy of person names in the surprise test was significantly better than that of animal names that served as a control group. Experiment 2 replicated Experiment 1 but increased the number of pre-surprise trials that could reduce the report accuracy of surprise test according to previous studies. The results revealed that the accuracy of the surprise test of person names decreased significantly, and showed no significant difference from that of animal names. These results suggest that there exists an automatic memory advantage of person names in working memory; however, such an automatic memory advantage effect could be reduced after participants learn to stop automatically encoding the attended but no-need-to-report person names through experiencing sufficient trials.
