What Is Memory? Defining Memory And Cognitive Function
Memory can be a straightforward concept in theory but may be more complex in study. It can work to remember events like losing your car keys to more complex and long-term memories like a childhood best friend. Memory is a part of almost every human process.
People use it to track appointments, learn languages, and avoid painful experiences. However, when memory fails, it can be distressing and confusing. Understanding how memory works and how it ties into cognitive function can be valuable in understanding your mind, whether you struggle with memory or have a strong sense of remembering.
What is memory?
According to the Merriam-Webster dictionary, memory is "the power or process of reproducing or recalling what has been learned and retained, especially through associative mechanisms." However, the word can also mean a commemorative remembrance, such as a monument.
Another definition of memory is "a particular act of recollection or recall" or "the image or impression of one that is remembered." This memory definition may be used when discussing positive or negative long-term memories of a past event like your childhood.
The process of remembering
The act of remembering may seem quick and straightforward if your memory is functioning normally. You may not think you are making any conscious effort to remember and that the memories sit in the brain. In addition, you might not be able to predict what form the memories take, remembering them as a whole or in bits and pieces.
When you struggle to remember information, you might devise a mnemonic device or wait until the memory reappears. Although this process can seem instantaneous, there are three specific tasks you use to retrieve this information.
Stage one: Encoding
Before you can remember a piece of information, it needs to be converted into a format that makes sense. There are three formats that the brain recognizes in the encoding process, including the following:
- Visual: Through visual encoding, you can convert information into an image, often called a "mental picture." For example, pairing someone's name with the appearance of their face is an example of visual encoding. Another example is remembering which way to turn at an intersection by recalling visual landmarks like buildings or street signs.
- Acoustic: You may also convert information into a "sound byte" by focusing on what you hear or repeating a phrase aloud. This technique is the kind of encoding used when you say a phone number out loud to remember it.
- Semantic: In this encoding type, you convert information into a format with special meaning. For example, you are partaking in this type of encoding if you remember a street address by associating it with a family birthday.
Encoding is often constantly done, almost without awareness. You may encode each event that happens to you, from your conversation with a coworker to the type of tool you choose to bring to a work function. In some cases, encoding requires a conscious effort, like saying a phone number out loud to remember it. Other times, it happens automatically.
Information may be forgotten when an effort to encode is not made or there are challenges with one's memory. For example, you may forget a phone number if you don't write it down or repeat it aloud.
Stage two: Storage
Psychologists have debated how much the human mind can remember for over a century. Some psychologists believe that long-term memory can store an unlimited amount of information. Others say that it could be impossible to remember everything. Researchers have concluded that one's short-term memory capacity is limited, and individuals can only store a finite amount of information at a given time.
For this reason, the brain has a system for storing and organizing memories. Initially, information is stored in short-term memory, which can remain for about 20 seconds. However, if you retrieve and use that information frequently enough, the brain moves it to long-term memory, where it can remain indefinitely.
Stage three: Retrieval
The final stage involves "recall," the act of remembering. This step may involve recalling the sequence you used to encode information stored in short-term memory. For example, if you want to remember how to make a particular type of food, you can recall the instructions in the order given to you.
What are the different types of memory?
People often know more about short-term and long-term memory. However, there are several types to be aware of, including the following.
Short-term memory
Short-term memory is used for what you pay attention to at any given time. Information in short-term memory does not last long and goes away if not maintained or rehearsed.
Sensory memory
Before information passes into short-term memory, it is first encountered by sensory memory. Sensory memory is the impression left by your senses, including information you immediately see, hear, smell, taste, or touch. The memory of these experiences lingers briefly after it's over, allowing you to store the information in your short-term memory.
Working memory
Commonly used as a synonym for short-term memory, working memory emphasizes that memories are only used for tasks you are immediately working on. Directions, to-do lists, and phone numbers are stored in this memory for the period you focus on them.
Long-term memory
Long-term memories are those that stay with you for a significant time. It could include memories that last a few minutes or your entire life. In theory, the capacity of long-term memory is unlimited. However, with many memories stored, it may be difficult to reach them. Below are the three types of long-term memory:
- Procedural: Procedural memories involve memories of how to complete specific tasks, like speaking a language, playing an instrument, or riding a bicycle. These memories are unconscious and automatic. They can involve what is called "muscle memory."
- Semantic: Semantic memories encompass common knowledge and are not drawn from personal experience. Examples could include the number system, the alphabet, and the names of the American Presidents. You may acquire these memories through purposeful encoding, storage, and recall.
- Episodic: Episodic memories involve specific events. You may witness or experience these events, which become part of your long-term memory through a complex encoding, storage, and retrieval process. Your memory of an event or experience is unique to you. No other person may remember it similarly because your emotions, thoughts, and later interpretations of the event can change how you see it in your mind.
What are memory lapses?
For some, age or brain damage can cause memory function to decline, especially for those with dementia or Alzheimer's. Memory can also be impacted by physical health conditions like a stroke, traumatic brain injury (TBI), or progressive neurological health condition.
Mental health may also impact memory. For example, individuals with anxiety regularly show poorer working memory performance. Individuals with depression have a more difficult time recalling happy memories. Other challenges, like stress and fatigue, can also cause memory challenges. In these situations, treating the mental health condition itself may improve memory.
Cognitive-behavioral therapy (CBT) is one of the most popular forms of therapy for various mental illnesses, including depression and anxiety. CBT helps clients reframe their thoughts, feelings, and actions, which can improve overall mental health. Studies have also found that CBT can be beneficial for those living with dementia. Another study found that CBT could improve mental health and memory while simultaneously reducing inflammation and improving the immune system.
Support options for memory challenges
Living with a memory challenge can be stressful and confusing. Whether it is caused by a disease, mental health condition, or another challenge, you're not alone. Talking to a therapist may be beneficial, as improving your mental health could improve your mental capacity to an extent. If you struggle to remember appointments and locations or can't drive, you might also appreciate the availability of internet-based therapy platforms like BetterHelp.
Studies have found that CBT can be as effective online as in-person for many clients, offering a convenient and cost-effective alternative to traditional therapy. With an online platform, you can work with a licensed therapist from your home or any location with an internet connection at a time that works for you. A counselor can help you determine if your memory challenges are related to mental health challenges and help you devise a treatment plan and goals for your future.
Takeaway
What is the simple definition of memory?
Memory is the cognitive ability to store, retain, and retrieve information and experiences acquired from the past. It involves the encoding of new information, its storage for future use, and the recall or retrieval of that information when needed. Memory may play a fundamental role in human cognition, allowing individuals to learn from their experiences, make informed decisions, and navigate daily life. Memory is not a single process, it comprises different types and systems, such as short-term memory, long-term memory, and sensory memory, each with its own functions and characteristics.
What is the human memory?
Human memory may refer to the cognitive process by which information, experiences, and knowledge are acquired, stored, retained, and retrieved for future use. It is a complex and multifaceted system that allows individuals to learn from their experiences, adapt to their environment, and interact effectively with the world. For memory researchers, human memory may not be a single, unified entity but rather comprises several different types and systems, each with its own functions and characteristics. The main components of human memory include:
- Sensory Memory: This is the initial stage of memory where sensory memories or information from the environment may be briefly held in its raw form. Sensory memory may act as a buffer, allowing for the initial perception and processing of sensory stimuli (e.g., auditory information, tactile information, and visual information).
- Short-Term Memory (STM): STM is the temporary storage system where information is held for immediate use and active processing. It may have limited capacity and duration and may be responsible for tasks that require the manipulation of information in conscious awareness.
- Long-Term Memory (LTM): LTM is the stage where information that is deemed important or rehearsed in short-term memory may be stored for more permanent retention. It has a vast capacity and can hold information for an extended duration, from hours to a lifetime. LTM is responsible for the storage of knowledge, experiences, skills, and facts.
- Working Memory: Detailed in a famous paper by George Miller, working memory is an active system that temporarily holds and manipulates information necessary for cognitive tasks, such as problem-solving, reasoning, and decision-making. Miller discussed that working memory was around 7 digits, plus or minus two. It is closely related to STM but emphasizes the active processing of information.
- Episodic Memory: Episodic memory stores personal experiences and events in a chronological and contextual manner, allowing individuals to recall specific episodes from their lives.
- Semantic Memory: Semantic memory contains general knowledge and facts about the world, such as language, concepts, and factual information that is not tied to specific personal experiences.
- Procedural Memory: Procedural memory stores information about how to perform various skills and activities, such as riding a bicycle, playing a musical instrument, or typing on a keyboard.
- Autobiographical Memory: Autobiographical memories are memories about ourselves, these may include major life events, changes, or transformations. These memories may be long-lasting due to their personal nature.
What are memories in life?
Memories in life are the recollections of past experiences, events, and moments that individuals have encountered and stored in their memory system. These memories encompass a wide range of personal and mutual experiences that shape one's identity, inform decision-making, and contribute to a sense of self and a connection to the past.
What is a memory definition for students?
Memory is the brain's ability to store, retain, and recall information and experiences from the past. It's like the brain's filing system, where it stores everything we've learned, seen, heard, or experienced. Memories can be about personal events, facts, skills, or even just everyday things like the taste of your favorite ice cream. Our memory helps us learn, make decisions, and remember special moments in our lives.
How is memory best defined?
Memory can be defined as the cognitive process by which information, experiences, and knowledge are acquired, encoded, stored, retained, and retrieved for future use. It encompasses the brain's ability to store a vast array of information and experiences, from facts and events to skills and emotions, and to recall them when needed. Memory plays a fundamental role in learning, decision-making, problem-solving, and everyday functioning, shaping our understanding of the world and our personal history. It is a complex and multifaceted mental process that is essential to human cognition and consciousness.
