Memory processes

Can u remember everything you did yesterday? What about last week or how about your first day at school? Yesterday will probably be easy but the further you go back they more faded the memory may be.

Memory is the process involved in retaining, retrieving and using information of what we seen and heard, after the original event has happened.

Like all things of the mind, memory is not a straightforward process. It involves many complex stages to become a long held memory in our minds for years to come. There are three stages known as The Modal of Memory:

First stage is known as Sensory memory:

▪ This stages holds all information for seconds or fractions of a second.

▪ All unattended sensory input is lost.

Second stage as Short-Term memory:

▪ This stage holds information that we have paid attention to for 15 to 20 seconds.

▪ We can only hold five to seven items during this time in our memory.

▪ Rehearsal ( like repeating a phone number) allows for the memory to stay longer in our thoughts, otherwise it get lost.

Last stage is known as Long-Term memory:

▪ This stage is where we transfer memories into our minds for years or even decades.

▪ There is unlimited capacity for the amount of memories we can hold here.

▪ Although, some information may be lost or become faded over time.

Think of memories like muscles, the more you use them the more stronger they become.

In a classic study conducted by George Miller “Seven plus or minus two”, our short-term memory has the capacity to hold five to nine items. Recent studies have shown that this can be expanded by ‘chunking’. This means putting smaller units together to create more larger meaningful units. A good example of this is with phone numbers instead of 4-1-7-1-2-3-4 it easier to remember as 417-1234.

An excellent technique to help you with studying, here’s a video to grasp the concept more:

What’s really interesting about memories is that sometimes they can be false. As we go about in our daily lives we are susceptible to people or events altering our memories, there has been lots of research on this phenomena known as: The Misinformation effect. A study conducted by Elizabeth Loftus and coworkers found they could alter participants memories of a video they has watched by given them false post event information of the video.

So back to my question at the start, but this time let me add some changes…. can you remember yesterday, accurately? Yes? But what about your first day at school? Still think it’s accurate? Over the years information you have pick up from stories other people tell of that day like your mom or maybe older sister may have altered they memory from what it originally was.

Might be a good idea to keep a diary…. to keep the record straight!😉
