Effect of delay interval and cue focality on prospective memory

The results showed that, compared to the non-delay group and no task delay group, participants in the 2-back delay group exhibited worse prospective memory performance, but better ongoing task performance after the delay interval task. The MPT model analysis showed that the delay interval only affected the prospective component of prospective memory and had no impact on the retrospective component. In addition, we found that the delay interval impaired prospective memory under different cue conditions by reducing the activation level of the prospective memory cues, thereby decreasing attentional monitoring of prospective memory.
