Secondary Memory
Memory plays a crucial role in shaping our understanding of the world. Secondary memory in particular is an important part of how we process events and make decisions about the future. However, secondary memories are not without limitations, such as bias, distortion, and the influence of emotions. Read on to learn more about the role that secondary memory plays in shaping our perceptions, how these memories are formed and stored, and their limitations. We’ll also discuss strategies for enhancing secondary memory and improving the accuracy and reliability of our memories.
What is secondary memory?
Secondary memory refers to memories that are stored in our brains for extended periods. Unlike primary or short-term memories, often referred to as volatile memory, which may only last a few seconds, secondary memories can be retained for days, weeks, months, or years. This type can allow us to recall past experiences, store knowledge, and retain skills. It can be further broken down into three subcategories:
- Semantic memory, which refers to our knowledge of facts and concepts, such as the meanings of words and knowledge about the world
- Episodic memories, which are of specific events or experiences in context, such as remembering a time when you felt joyful and also recalling where you were and what you were doing when you felt that way
- Procedural memory, which is the ability to remember how to do things we learned previously, like playing the piano or driving a car
The mechanics of secondary memory
You may view secondary memory as analogous to a computer's secondary storage devices, like the hard disk or solid state drive. If we view the CPU as our brain, the primary memory of our brain is closer to a computer's RAM with its short-term memory, also known as the working memory, whereas secondary memory devices are more like the hard drive, storing long-term data that the user may connect at any time. A secondary storage device is permanent, and can be recalled, much like our secondary memory.
Secondary memories are formed through the process of consolidation, which involves transferring information from short-term to long-term memory. This process occurs over time, and can be influenced by factors like repetition, emotion, and attention. Once the information is consolidated, the brain's storage capacity allows the information to be stored in multiple regions, including the hippocampus, the amygdala, and the neocortex. Typically, the hippocampus encodes information and data, while the amygdala processes related emotions and assigns emotional significance to the memory. The neocortex is involved in storing and retrieving information later.
How we use secondary memory
Our secondary memory is instrumental in shaping our understanding of the world. It allows us to construct a mental representation of reality that’s shaped by our past experiences, beliefs, and values. This mental representation becomes the lens through which we view and interpret new information and experiences.
Our secondary memory also influences our beliefs, attitudes, and biases. For instance, if an individual has had positive past experiences with dogs, they’re more likely to have a positive perception of dogs in the future. If they had a bad past experience with a dog, however, they’re likely to apply the emotions they felt—such as fear—to future experiences with dogs. If they have additional interactions that are negative, those will typically serve to further reinforce their preexisting attitudes.
How secondary memory can impact emotions and behaviors
Our secondary memory not only shapes our perception of the world but can also profoundly impact our emotions and behaviors. One reason is that emotional experiences tend to leave a lasting impression on our secondary memory. This might be because the amygdala, which processes emotions, is closely linked to the hippocampus, which encodes and decodes information. As a result, emotional experiences are likely to be stored in our secondary memory more vividly than neutral experiences.
This might be why we often react strongly to a number of events associated with past emotional experiences. For example, if you’ve had positive experiences with public speaking, you may approach and engage in it confidently in the future. On the other hand, if you’ve had past experiences with public speaking where you felt anxious, nervous, stressed, or embarrassed, you’re likely to instinctively avoid it or behave nervously when presenting in front of others because of these strong memories.
The limitations of secondary memory
Secondary memory is a valuable tool, but it has limitations. One of the most significant is its subjectivity to bias and distortion. Over time, memories may become distorted, altered, or even completely fabricated. This could result in false or inaccurate memories that could significantly impact our beliefs, attitudes, and behaviors. For instance, if you come to vividly remember an event that never actually occurred, or remember an event very differently from how it actually happened, you might act on that version of the memory as if it were true. Misunderstandings, miscommunications, and poor decisions based on false information could result.
Another limitation of secondary memory is its susceptibility to emotions and biases. Our emotions can color how we perceive and remember events, and our biases can influence how we interpret and recall information. Over-relying on these past perceptions could result in a skewed view of new situations and could more easily allow us to reinforce negative attitudes and beliefs.
What happens when we over-rely on secondary memories
That’s why acknowledging the limitations of our own secondary memories and being open to other information sources can be helpful for developing a healthy, balanced perspective on ourselves, our past, and the world. Other risks of overreliance on our own secondary memories may include:
- Increased stress and anxiety. Relying too heavily on our own secondary memories may cause us to experience stress and anxiety when these memories are challenged. It may also make it hard for us to process new situations that offer input that conflicts with what we remember or our preexisting judgments.
- Reduced flexibility and adaptability. Over-reliance on secondary memory might also make us overly attached to our past experiences and beliefs. As a result, we could become less flexible and adaptable, making it difficult for us to embrace new perspectives and learn from new experiences.
- Reinforcement of negative beliefs and attitudes. If negative experiences and beliefs dominate our secondary memory, we may become stuck in a cycle of negative thinking that reinforces these attitudes. Feelings of hopelessness and helplessness that negatively impact our well-being could be the result.
- Inaccurate or false memories. Over-reliance on secondary memory could also increase our risk of creating inaccurate or false memories. As time passes, the way we recall events may become distorted or altered, which can lead to misunderstandings and miscommunications.
Tips for cultivating a strong, balanced secondary memory
If you’re looking to enhance your secondary memory and improve memory accuracy, there are some strategies you can try. First, you might simply make it a practice to focus on the details of an experience as it’s happening. Engaging in a regular mindfulness practice may help you develop the awareness and presence to be able to do this more easily. Journaling about your experiences shortly after they happen can also help you retain details more accurately.
To help keep a balanced perspective rather than letting the emotion of past experiences wholly dictate how you approach new situations, simply developing an awareness of this human tendency may be key. If you notice yourself forming emotional pre-judgments about a person or situation, you might benefit from stepping back and trying to take a more objective view. Experiencing new things with a more open mind and being willing to entertain other perspectives can help you avoid limiting yourself based on subjective memories.
How therapy can help
Therapy can be a valuable tool for addressing the natural limitations of secondary memory. A therapist can offer you a safe, open space where you can process and reflect on past experiences. They can also help you learn to recognize when these experiences may be influencing new situations you encounter so you can avoid limiting yourself in this way. If an over-reliance on your own subjective secondary memories has caused you to get stuck in a cycle of negative thinking, they may also assist you in learning to break the pattern and develop healthier modes of thought.
In most cases, people who are interested in seeking therapy can choose from either online or in-person sessions. Research suggests that both can offer similar benefits, so you can typically choose the one that feels right for you. Some people prefer online therapy because of its relative convenience and affordability. With a virtual therapy platform like BetterHelp, for instance, you can get matched with a licensed therapist who you can meet with via phone, video call, and/or in-app messaging from the comfort of home, or anywhere you have an internet connection.
Takeaway
What is the difference between primary and secondary memory?
Primary and secondary memory are differentiated by how long information is stored and how it is accessed.
Primary memory: Primary memory, also called short-term memory, refers to information actively in the conscious mind. For example, you may be able to recite your to-do list for the day.
Secondary memory: In addition to short-term memory, the mind will also store data that can be retrieved later. This type of memory is called secondary or long-term memory, and it’s often equated to using storage devices, like hard drives, for a computer.
Primary and secondary memories are not the only types of memory in psychology. Related types of memory include working, sensory, prospective, and volatile memory.
What is secondary memory in humans?
Secondary memory is also called long-term memory. Secondary memories are differentiated from other memories because the information stored may be retrieved far in the future—often days, weeks, months, or years later.
There are three types of secondary memory:
Episodic memory: These memories revolve around specific experiences. For example, you might remember your fifth birthday fondly or the excitement you felt when you got to hold a penguin at the zoo.
Semantic memory: This type of long-term memory revolves around facts. For example, you might remember how much a T-Rex weighs, or the definition of words you learned when studying for the SATs.
Procedural memory: These memories help you remember how to do things, such as driving home from work without directions or brushing your teeth.
Memories in the human brain have some similarities with computer memory. Primary memories are stored as on computers as Read-Only Memory (ROM) and Random Access Memory (RAM). Secondary memories may be stored on hard drives and flash memories, and they can store much more data (such as entire operating systems or application programs).
What is secondary memory?
Secondary memory is the same thing as long-term memory. These memories are stored in your brain for the long term and can be recalled in the conscious mind with specific cues. For example, if you’re applying for a job and asked interview questions like, “Recall a time that you used problem-solving skills to overcome a challenge,” you might recall an event that you hadn’t thought about in years.
What is the difference between primary and secondary memory in psychology?
Primary memory refers to the relatively small amount of information you are conscious of (also called short-term memory). Secondary memories are a much larger database of long-term memories that you retrieve back to your consciousness when you encounter specific cues. For example, if you’re working on a house project, you might recall the volume of a rectangular prism (length x width x height) that you learned in fifth grade.
What are the two types of primary and secondary memory?
Primary memory, also called short-term or active memory, is the small amount of information currently in your conscious memory. These memories last approximately 15-30 seconds, allowing you to remember a sentence while reading a book or recite a phone number. This information can be kept in your short-term memory through recitation.
Secondary memory is long-term memory, and it stores much more information than primary memories. There are three subtypes of secondary memory:
Episodic memory: These memories include specific experiences, events, or incidents. You can often “look back in time” at episodic memories, like your high school graduation or your wedding day.
Semantic memory: These long-term memories include common knowledge, facts, figures, or basic information.
Procedural memory: This is implicit memory for performing tasks like brushing your teeth, using a fork, riding a bike, or tying your shoes.
What is main memory primary or secondary?
Primary memory is considered the main type of memory because it includes everything in your conscious awareness. Secondary memories, in contrast, must be retrieved from storage to be brought into conscious awareness.
What is an example of a secondary memory?
Examples of secondary memories include remembering how to ride a bike, reflecting on an event that occurred last week, or being able to recall the Pythagorean theorem.
Why do we use secondary memory?
There is very little information that can be held in your conscious awareness or short-term memory. Secondary, or long-term memories, allow you to retrieve and use information that you may have learned days, weeks, months, or many years ago.
Is secondary memory short-term?
Primary memory refers to short-term memory, whereas secondary memory is long-term memory. There is relatively little information in our short-term memory at any given time, but secondary memory has a far greater ability to store information that can be retrieved in response to specific retrieval cues.
What is primary memory also known as?
Primary memory is also known as active, main, or short-term memory.
