Memory is really important! We need it everyday to live, without it, it would be impossible to live. What you are doing right now, requires memory. Your brain is constantly working. As you are reading this, your brain is working. Memories strengthen our sense of identity and purpose and bond our relationships. Happy memories are an important ingredient in present happiness! We use it everyday, like remembering your password to your iPad, knowing the way to your house when driving, and remembering what homework you had. Memories are important because it shows us the past, and what we have remembered. We can have good and bad memories.  That is why we treasure our memories so much – they are records of the most important  moments of our lives, they enrich our lives and help us through hard times. We can recollect most precious moments from the past at any time and relive the joy they brought us. Memories  can work with our temporal lobe. The temporal lobe contains the hippocampus, a region of the brain important for memory, learning and emotions.

People who experience sleep apnea may be more likely to also have memory or thinking problems, according to a preliminary study. The study shows a positive association but did not determine whether sleep apnea causes cognitive decline.
Sleep apnea is when people stop and restart breathing repeatedly during sleep which can lower oxygen levels in the blood. Of all participants, 1,079 reported symptoms of sleep apnea.  There are also other factors that come into play such as

Motivation/Repression

Painful memories...we don’t want to remember these!

Brain Damage

Amnesia

Alzheimer’s Disease

Dementia

Of those with symptoms, 357 people, or 33%, reported memory or thinking problems compared to 628 people, or 20% of people without sleep apnea symptoms.

Normally, a person's pupils naturally widen (or dilate) in low-light environments to allow more light into the eye. However, in a new study, researchers reported that a person's pupils also dilate when they are concentrating on tasks. In particular, they found that the more a person's eyes dilated during the task, the better they did on tests measuring their working memory. During the tasks, participants had their pupils continuously measured using an eye-tracker, similar to what optometrists use during eye exams.

Functional Fixedness

The tendency to think of things in terms of their usual functions

An example- The inability of someone to realize that they can use a wrench to drive a nail into a piece of wood and not just a hammer is an example of functional fixedness.

Problem Solving obstacles
Mental Set
Tendency only to see solutions that have worked in the past
For instance, if one were working on a tough math problem, I  would refer to their own previously developed mental sets to aid in the solution.

Another problem solving strategy, is Heuristic.
This is

Problem solving shortcuts that reduce the number of steps to solving a problem.

A real life examples is

A person is stuck in traffic and makes an impulsive decision to take the other route even though you don't know the way.

Someone is offered a job and accepts it without further details.

A family chooses to move to another country without being familiar with the language, culture or area.

Here’s another tip!
Sometimes we can forget things, (Refers to the inability to retrieve, recall, or recognize info that was stored or is still stored in long-term memory) this also can cause interference (Refers to the inability to retrieve, recall, or recognize info that was stored or is still stored in long-term memory)

It’s easier to retrieve information when  it is most efficient when an individual is in the same state of consciousness as they were when the memory was formed. This is when you are state-dependent

”Be happy and ina good mood when you study then! 😊😊put some tunes on like pitbull!

Take one five-minute break each hour to give your brain a chance to relax and process information.

Get at least six hours of sleep and don’t skip any meals. This will help you concentrate and perform on test day. Don’t forget to set your alarm

Two long term memories

I remember the day I put my dog down, I was so sad. I was bawling my eyes out, her name was Bear- Bear. She lived until she was about 15 years old, she was a pug and shih tzu mix. When I heard the news that my parents were going to put down my dog, I bawled my eyes out. I wasn’t at home, I was at my brother’s house in Crystal Lake.  I was sad for a couple weeks and grieve but I got over it! Me and my family are now thinking of getting a new dog.

My other memory is I remember when I was turning 10, and I Had my birthday with my friends at Burger King. Boy, it was the happiest day of my life. Me and my friends were wearing  the crowns they gave at Burger King. I remember all my friends had kids meals, and there I was sitting down eating my Burger King whopper.  I’m pretty sure I had a lot of dopamine, (pleasure neurotransmitter, and seratonin (contributes to well being and happiness.)

With the brain, there is an effect called the context effect .  This is when the context or location around the memory are the same for both the original encoding and retrieval.

Short Term Memory Lane

I remember my best friend gave me her phone number, I thought I remembered it, because the middle numbers looked so similar to my other friend’s number. One time I called my best friends number, and I didn’t even realize it was my other friends. I called the number, and my friends mom picked up instead of her!! It was so embarrassing.  🫢🫢🙀🙀🙀😳😳😳

Types of Memories
Sensory Memory:

initial process that receives and holds environmental info for several seconds

iconic = visual

echoic = hear

Short Term Memory:

Working memory

Holds info for 2 - 30 seconds

+/- 7 items

zip codes, passwords, phone numbers

retain. info. BRIEFLY!

Long Term Memory:

Process of storing almost unlimited amounts of info over long periods of time

Problem Solving Strategies

Algorithm- A fixed set of rules or procedures that will guarantee a solution

A real life example that I use an I am pretty sure everyone uses is tying your shoes, or doing a math equation!

Do you want to know how to retain knowledge? Or maybe want to do good on an exam? Well hear me out!

Use Mnemonics! They are tools that help us remember facts, large amounts of information, and retain information. They help stimulate memory through songs, pictures, acronyms, rhymes, or other devices. Having to do brain teasers also helps your brain out. In fact, they help build

NEUROPLASTICITY!!!!

Form new neural pathways

Brain Teasers  are also good for the brain! They

Stimulate cognitive abilities

Encourages creativity

Aids concentration

The 3 processes of memory include, encoding, storage, and retrieval.  Encoding is mental representations of information so that it can be placed into our memories. Storage is process of placing encoded information into relatively permanent mental storage for later recall. Retrieval is clue or prompt that is used to trigger the retrieval of long term memory.
