Think back on the most impactful memories you have. The ones that you recall clearly, as if the event just happened, likely have strong emotional reactions tied to them. Read on to learn about emotional memory and how it influences what—and how—you remember.

Do you know how your emotions affect your memories?

What is emotional memory?

According to the American Psychological Association (APA), emotional memory is the recollections tied to events that elicit an emotional response. The APA said memories could be implicit (nonconscious) or explicit (conscious), and memories connected to strong positive or negative emotions are retained better due to activity in the amygdala region of your brain. 

How your brain creates memories

Multiple parts of your brain are engaged in the creation, retention, and recollection of memories. Brain cells called neurons transmit electrical signals via neurochemicals. Your frontal lobe is involved when you think, neurons fire in the amygdala during emotional reactions, and the hippocampus is integral to long-term memory. 

The role of the amygdala

For many years, the amygdala has been known as a crucial aspect of how the brain creates and retains emotional memories. A 2014 study examined how neural plasticity in this brain region during the arousal of strong emotions could benefit the clarity and strength of memories. The amygdala plays a vital part in the modulation of memory consolidation. Additionally, studies show that damage to the amygdala region of the brain can reduce the memory-enhancing benefits of emotions on cognitive processes and memory encoding. 

Why some memories have more strength and clarity

Memory traces are the mental images you form while creating memories, and the more you make, the more accurately you may remember the event and its details. Children tend to produce more memory traces than adults in a given period, so they often recall events with greater awareness and visual info. According to a 2009 study, the engagement and enjoyment of an event can also affect how you remember it by shifting the number of active neurons during memory creation. Strong negative feelings also count as engagement, which can help explain why it’s so easy to remember traumatic experiences. 

How your emotions can strengthen memories

Though the definition of “emotion” is subjective to the individual and their knowledge, it carries a general meaning of what people feel in reaction to what they experience. 

Research indicates that memories influenced by strong emotions can be easier to recall because of the neurochemicals released by the brain at the time of memory encoding—the process used to modify and store sensory information. 

Characteristics of emotional memory include the following:

  • We tend to remember traumatic memories more clearly.
  • Remembered details change over time.
  • Fact-based memory isn’t as powerful as emotional memory. 
  • Emotional memory can retain and recall suppressed and forgotten memories. 
  • Your mood can affect your emotional memory. Your memories can also affect your mood. 

The impact of emotion on your memories

When you experience an event that evokes an extreme emotional response, you are more likely to form a clear memory of the situation and recall it much later. For example, if you find an old photograph taken on an exceptionally wonderful day, your memories may be so vivid that you “remember like it was yesterday.” 

According to a recent study, emotions can significantly influence how your brain conducts cognitive processes, such as perception, learning, memory, attention, problem-solving, and reasoning—all of which can have a selective effect on your memories depending on what evokes your emotions. 

Traumatic events and memory

However, this effect works both ways, and you may be reminded of unpleasant memories with clarity and a surge of emotions you’d rather not experience again. For example, you may not remember the name of your elementary school bully, but the details of the hospital room a loved one passed away in may be seared into your memory—down to the scent of the floor cleaner. While much of that information serves no purpose, it was part of your sensory input during an emotionally traumatic event. Your brain assigns more importance to every aspect of that memory. 

While traumatic experiences may create detailed memories for some people, for others, they may trigger selective memory loss in the form of forgotten or suppressed memories. According to the Cleveland Clinic, this condition is called dissociative amnesia, and it is typically associated with stress and trauma.

How humans remember—and forget 

German philosopher Hermann Ebbinghaus presented a psychological theory called the Curve of Forgetting in the 1880s, demonstrating how quickly humans forget information they don’t use regularly. According to the Ebbinghaus Curve, when info isn’t repeated or reviewed, approximately 40% will be lost in the first 24 hours. At 48 hours, that number increases to 60% and continues growing as time passes. 

Misplaced confidence and memory over time

Often, it isn’t the memories themselves that hold them in your memory. After all, to the brain, one memory is generally as important as any other if there isn’t an emotional connection. However, your level of confidence in your recollection of the event may encourage the details to linger for years. Memories can shift over time, with the details often changing as the years pass and your brain makes space for other memories. For example, witnesses to a crime are often considered less reliable as the case progresses because time and retelling can distort the memories. You may feel misplaced confidence in your ability to remember the event clearly after some time, and your mind may invent details to fill the gaps in your memory. 

Memory strength: Fact-based vs. emotional

According to a 2013 study, fact-based memories don’t evoke the same level of engagement as emotional memories, which can often make them more challenging to recall. For many people, a decade or two out of high school, much of the information they learned in school has been forgotten. While those memories may have faded, you almost certainly have other experiences from the same time period that you can recall clearly because they are centered on events that elicited emotional reactions. 

The link between memory and mood

Your emotional state at the time can color what you remember about an event and how you remember it. Research from the American Psychological Association indicates that your emotional reactions to positively or negatively exciting events can affect what you retain about the moments immediately before and after the situation. However, while researchers can agree that emotions can affect your memory of an event, it has been challenging to consistently replicate the results, showing that selective emotional memory may be as unique as the individual experiencing it. 

Your mood may also affect what you remember. For example, when you are in a sad mood, you may recall other memories that made you feel the same way. Or perhaps memory is triggered because you associate it with a specific feeling, such as feeling great excitement over winning a contest in elementary school and remembering that feeling every time you experience heightened excitement. 

How mental illness can affect emotional memory

Many people experience memory challenges due to mental health conditions. When something influences your emotional stability and control, you may have trouble forming and recalling memories of your experiences. 

Mental health conditions that can affect your emotional memory include the following:

  • Mood disorders like depression can make it hard to feel strong emotions like excitement, which can strengthen emotional memories. 
  • Anxiety disorders can make worry or fear the dominant emotion you feel, changing what you remember about an event. 
  • Many mental illnesses can impact how you experience emotions, so this list could expand exponentially. If you are concerned about your mental health, please speak to a therapist to learn about your options. 

How therapy can help you organize and process emotional memories

Working with a licensed therapist online through a virtual therapy platform such as BetterHelp offers a healthy, effective way to explore, process, and organize your emotional memories. Various therapies are used to improve your understanding of memory and help you improve your cognitive strength. Online treatment is typically less expensive, more available, and offers convenient, flexible appointment formats. 

Cognitive stimulation therapy (CST) is a memory-focused therapy often used with dementia patients. It focuses on activities and exercises centered on thinking, communication, concentration, and memory. Even without cognitive disorders, this may be an effective memory maintenance method because the therapy involves recalling and describing past events and memories in relation to the current time and place. It may be helpful for someone hoping to learn ways to better understand and organize their emotional memories. Studies show that online CST is a viable treatment option
