The autobiographical memory system refers to an individual's ability to store, retrieve, and reconstruct memories of past personal experiences. Within the context of negative emotional experiences, this system plays a critical role in shaping an individual's current emotional states and cognitive evaluations. When individuals encounter negative emotions, the autobiographical memory system often automatically activates related past events, leading to the association or reinforcement of current feelings.

Research indicates that negative emotional experiences can enhance the retrieval of memories with similar emotional tones, a phenomenon known as mood-congruent memory. For instance, when experiencing sadness, individuals are more likely to recall past events associated with sadness, thereby intensifying their current emotional state. Moreover, the autobiographical memory system is not merely a passive repository of information; it actively reconstructs past experiences. During this reconstruction process, individuals may reinterpret or reevaluate past events based on their current emotional and cognitive states, further influencing their present feelings and behavioral responses.

Additionally, the autobiographical memory system interacts with other cognitive functions, such as attention and executive control. In negative emotional states, attentional resources may be biased toward memory content related to negative experiences, making it difficult for individuals to disengage from these memories. This, in turn, sustains or exacerbates negative emotions. The executive control function, on the other hand, can modulate this process by inhibiting the excessive retrieval of negative memories or by reinterpreting past experiences, thereby alleviating the impact of negative emotions.

In summary, the autobiographical memory system serves as a bridge connecting past experiences with current emotional states in negative emotional experiences. By retrieving and reconstructing past memories, individuals derive and reinforce their present feelings. Understanding this mechanism has significant implications for clinical psychological interventions, such as cognitive-behavioral therapy and memory-specific therapies, which aim to help individuals alter their emotional responses by restructuring negative autobiographical memories.
