Prospective memory is an important and complex social cognitive ability, which is easily disturbed by negative emotions. According to the relationship between prospective memory cues and ongoing tasks, prospective memory can be divided into focal prospective memory and non-focal prospective memory. This study focuses on the influence of negative emotions on different types of prospective memory. In Experiment 1, 117 participants were recruited, using a 2 (emotion: negative, neutral) × 2 (cue focality: focal, non-focal) between-subjects design to initially explore whether negative emotions can interfere with the prospective memory of both focal cue and non-focal cue. The results show that negative emotions simultaneously reduce both types of prospective memory performance. At the same time, negative emotions occupy additional attention resources and impair the prospective component of prospective memory with non-focal cues. In Experiment 2, 64 participants were recruited to improve the difficulty of the retrospective component of prospective memory with non-focal cues, and the influence of negative emotions on different components of prospective memory with non-focal cues was further explored. The results show that negative emotions can impair both the prospective and retrospective components of prospective memory. In short, the results of this study indicate that negative emotion can impair prospective memory, and the impairment effect is not limited by the cue type of prospective memory. Meanwhile, negative emotion will occupy more attentional resources and simultaneously affect the prospective and retrospective components of prospective memory.
