At My Story Told, we know the true value of documenting your memories for future generations. We also have the skills and experience to guide you on this journey, and ultimately provide you with a stunning personal keepsake that tells your story, your way.
Our previous blog ‘what are memories?’ outlines how memories are formed and their benefit to us in everyday life.
Here, we delve deeper into the different ways our memory works, and the relevance and importance of the different types of memory in how we view, and feel about, the past.
Types of memory
While there have been many differing theories proposed surrounding memory, the most basic of these was first proposed in 1964 by Richard Shiffrin and Richard Atkinson, which outlines the three stages in logging memory to be sensory memory, short-term memory and long-term memory.
Sensory memory is the initial stage of the process, where information solely from the environment is stored for very short periods of time (half a second for visual information and three to four seconds for auditory information).
This stage of the process allows the brain to retain impressions of sensory information following the removal of particular stimuli. For example, if you’ve seen traffic rush by at night, the light appears to leave a trail. The reason for this is “iconic memory”, where visual cues are stored for a short duration. This is also like waving a sparkler and seeing a circle form from the ember. The sparkler isn’t actually creating a line, your eyes just cannot process the information quickly enough when it’s in motion, so what you see is a trail.
There are also other sub-categories of sensory memory: echoic memory (auditory), haptic memory (touch), olfactory memory (smell) and gustatory memory (taste). Echoic memory is seen in spoken language. When you are listening to somebody speak, your brain is registering and retaining each individual syllable which are then pieced together to form words. Similarly, to take it a step further, words are registered and retained individually and pieced together to form sentences.
Haptic memory refers to the recall of a sensation involving touch. For example, the feeling of a raindrop touching your skin is stored by the brain so that you can recognise what is happening. Additionally, sensory memory can also involve smell (olfactory) and taste (gustatory). These two somewhat work in tandem but individually can work in developing memories when experiencing the stimuli again. It is a well-known phenomenon that certain tastes and smells from your childhood immediately remind you of that earlier time in your life, conjuring all the associated visuals and emotions from that specific moment. The primary function of sensory memory is to provide a detailed sensory overview of which the most relevant chunks of information are extracted and processed by “working memory”, the next stage of the model.
Also referred to as working memory, short-term memory extracts relevant information for around 30 to 40 seconds, and a large percentage of this is forgotten quickly. Short-term memory is estimated to hold between 5 and 9 items at any one time.
Information progresses to the next stage of the model through processes like rehearsal. Think about when you get a new phone number, at first it seems impossible to remember, but once it is recited enough, you can. Interruptions to rehearsal processes can result in losing that information.
Long-term memory contains the information deemed relevant enough to be continuously stored. Information stored within long-term memory is utilised through a process called retrieval.
Long-term memory also has many sub-divisions, including explicit or declarative memory, which involves information that is consciously stored or retrieved. An example of explicit memory is a fact taken out of context, such as, “Cardiff is the capital of Wales”, this information is readily stored and retrieved.
Our long-term capacity is extraordinarily vast, and some memories stay with us for life. These are the memories that we care about, the ones that have stood the test of time and deserve to be shared.
