Background Several studies have shown that the retrieval of positive memories may play a role in emotional regulation. However, it is unclear whether the effects of neutral and positive autobiographical memories differ. It is necessary to confirm whether genuinely neutral autobiographical memories can be retrieved without bias when prompted to recall neutral memories. Methods In this pilot study, using “home” and “study” as cue words, we investigated whether participants were able to retrieve appropriate autobiographical memories when asked to recall a limited number of neutral or positive memories. Results Although participants were asked to recall neutral autobiographical memories, they tended to recall positive memories. Conclusions Our results support the concept of positive memory bias and suggest that future work should consider combining neutral and positive autobiographical memories by asking participants to recall neutral–positive memories.
