摘要	Prospective memory (PM) refers to memory for future intentions. Difference due to memory (Dm effect) is the difference in neural activity related to stimuli that were subsequently remembered or forgotten. Using event-related potentials (ERPs), the present study investigated the Dm effect for PM using a subsequent task-switching paradigm. The results showed that a Dm effect of ERP P150 was more positive-going for later PM hit trials than for later PM forgotten trials during 100-200 ms. This Dm effect may reflect the process for the production of future intention or the process for attention. Consistent with previously reported Dm effects of other types of memory, we found that the fbN2 (250-280 ms) and late positivity component (400-700 ms) were stronger in later PM hit trials than in forgotten trials. The fbN2 was evoked by Chinese characters. The late positivity component was related to the precise encoding process. In conclusion, because of the early P150, PM encoding appears to be somewhat different from previously identified Dm effects. However, further research is needed. Our findings reveal that Dm effects of PM share similar characteristics with known Dm effects of other types of episodic memory after the very early stage of neural processing.
