How do stress hormones primarily affect memory?

Stress hormones play a significant role in memory processes, particularly in how they influence memory consolidation. When a person experiences stress, the body releases hormones such as cortisol and adrenaline. These hormones can enhance the consolidation of memories, particularly emotional or significant events, by strengthening the neural connections associated with these experiences.

This process occurs because, during stressful situations, the amygdala—an area of the brain involved in processing emotions—activates and communicates with the hippocampus, which is crucial for forming and storing new memories. The heightened levels of stress hormones can lead to improved memory consolidation for stimuli that are emotionally charged or relevant to the stressor.

While stress can indeed impact memory in various ways, the primary mechanism through which stress hormones exert their influence is through their effect on memory consolidation. This explains why the correct answer addresses this aspect specifically.
