It doesn’t matter if you’re 30 or 70, at some point in your life, you’ll ask yourself, “How can I forget something like this?” In fact, there is no explanation that can be relied upon, but it is known that our memory forgets some events easily and we keep the rest of the events without a clear scientific reason.

Perhaps the reason is due to the evolution of memory throughout human history, as it is a vital factor to allow the survival of events that we will only understand through a concrete or painful experience, for example, if we approach a fire for the first time we will inevitably burn ourselves, memory will allow us to remember this moment for life even Don’t repeat it, and this applies to almost everything.

In fact, this has to do with the types of memory that exist. There are many theories in this regard, but the most scientifically plausible are those formulated by Larry Squire, professor of psychiatry and neurosciences in America, at the end of the twentieth century. Squire distinguished between declarative memory and non-declarative memory, each of which affects different aspects of life and has different characteristics. According to a report published by the confidential.” Translated by home.

types of memory

Declarative (explicit) memory is responsible for the autobiographical memories accumulated in our lives and the knowledge we acquire, and depends primarily on the integrity of the medial temporal lobe, which significantly enhances learning and memory performance by up to 15 percent.

Explicit, or declarative, memories also include all memories available in consciousness. Explicit memory can be divided into episodic memory (specific events) and semantic memory (knowledge about the world).

For its part, non-declarative (implicit) memory is responsible for learning motor skills, such as driving or riding a bike, that are acquired through experience. It depends on the brain’s subcortical structures.

Implicit memories, too, are those that are often unconscious. This type of memory includes procedural memory, which includes memories of body movement. How you drive a car or use a computer are examples of procedural memories.

Larry Squire distinguished between two types of memory: declarative and non-declarative.

As two different types of memory are encountered, there are conflicting results when it comes to dealing with the varying processes that unfold in life. The response of one type of memory to a pathological condition such as dementia or to an unsatisfactory process such as aging will be different. Thus, behavior and reactions will vary.

In sum, declarative memory, which includes a person’s autobiographical memories, is more fragile than non-declarative memory. So, a person with dementia can remember how he played the piano when he was young.. In fact, he would be able to play a song, but he would not be able to remember what he had for breakfast that morning.

Declarative memory, which includes autobiographical memories, is more fragile.

But in addition to the differences between declarative memory and non-declarative memory, there are other factors that can play a critical role in what a person remembers and forgets. One of the most important factors is the emotional content of the live experiences, the more excited you are, the easier it is to remember.

How do I remember and how do I forget?

Experts consulted by the BBC agree that memories with higher emotional content stay in our memory longer. Our wedding day, the birth of a child, or the day you entered your new home for the first time, are just a few examples of the emotional memories that are hard to forget.

This happens because our emotional system conveys to our memory the importance we attach to a particular experience, whether it is positive or negative. This is why it is also possible to remember the last words of a loved one before his death or a traumatic situation, which we experienced at a particular moment in our lives. Another factor confirmed by researchers, of great importance to us is the attention we give to a particular event.

For example, if we don’t find the phone at home, it’s not only because of our bad memory, which can really be, but it could be because of the lack of attention we paid to the phone when we used it for the last time, maybe because we focused on something else during Carry it like, a conversation with family or a friend or an important news on TV, or getting dressed to get ready for work, etc.

“You can remember how to play the piano, but you can’t remember what you ate for breakfast at the same time.”

In conclusion, experts point out that the memories that arouse a person’s attention do not end, and therefore, we will not be able to remember all events at the same time. And just as there are people who forget so easily, there are others who are able to manage these cognitive resources and, therefore, they will remember better where they last left their phone or what they ate for breakfast this morning.
