Part II Storage and Retrieval Memory Part II Storage and Retrieval

Memory – Information Processing “Three-Stage Processing” Model Memories are stored in a three-step process of sensory memory, short-term memory, and long-term memory

Memory – Information Processing Sensory Memory – the immediate, initial recording of sensory information; fleeting, to-be-remembered information

Memory – Information Processing Short-Term Memory – activated memory that holds a few items briefly, such as the seven-digits of a phone number while you are dialing, and then the information is either stored, or forgotten

Memory – Information Processing Long-term Memory – the relatively permanent and limitless storehouse of memories

Sensory Memory Sensory memory retention is only fleeting and momentary Sensory memory retention allows us to remember small, quick bits of information for a very short period of time

Sensory Memory G Z E P R K O D B T X F

Sensory Memory How many letters can you recall? Most people can recall four or five letters in that short of a time span, but know that there were more.

Sensory Memory Sensory memory retention is what is used when you see a face in the crowd for a split second….you recognize features quickly, determine she/he was cute, but then you can’t remember any details of their face

Sensory Memory Was he/she cute? What was he/she wearing? What color was it? What color was his/her hair? How long was it? What color was her lipstick? What was his/her facial expression? What color were his/her eyes?

Short-Term Memory or Working Memory The ability to hold and manipulate information over a brief period of time. Forgetting can occur rapidly, especially if distracted

Short-Term Memory or Working Memory Short-term memory has two important characteristics. First, short-term memory can contain at any one time seven, plus or minus two, "chunks" of information. Second, items remain in short-term memory around twenty to thirty seconds.

This type of memory increases as children get older… Short-Term Memory This type of memory increases as children get older… …but decreases in old age

Activity Pens and pencils DOWN Look at the picture You will have15 seconds

Write down the words of all the pictures you can remember. Short-Term Memory Write down the words of all the pictures you can remember. How many objects did you remember?

Short-Term Memory We can only consciously process a very limited amount of information in our short-term memory.

Short-Term Memory We can only consciously process a very limited amount of information in our short-term memory. Overload your short-term memory? You might forget what you read, ask yourself where you put your briefcase, and ask your phone partner the same thing twice.

Long-Term Memory A system in the brain that can store vast amounts of information on a relatively enduring basis The information can be facts you learned a few minutes ago, personal memories that are decades old, or skills learned with practice.

Long-Term Memory The average adult has more than a billion bits of information in memory Storage capacity of long-term memories has been estimated at million times that (1,000,000 X 1,000,000,000)

Retrieval Retrieval is the process of getting information out of memory storage You may need to remember exact facts and figures, or you may only need to remember general terms and identifications.

Retrieval Recall – memory is the ability to retrieve exact information learned at an earlier time IE. Fill in the blank test. IE. Columbus sailed in the year ________. 6 x 6 = _____. Define retrieval ______. My Social Security number is _______.

Retrieval Recognition – a measure of memory in which a person only needs to identify items previously learned IE. A multiple-choice test. IE. Of the following choices, which is the correct answer to 6 x 6 ____. You can’t remember the names of all 400 kids you graduated high school with, but if I show you pictures of them you can remember who you went to school with and who you didn’t.

Retrieval Relearning – the principle that if you’ve learned something and forgot it, you probably will learn the material more easily the second time – therefore, retrieval is easier and quicker as well IE. Learned to play the guitar and played for five years. Haven’t played in 10 years, but you pick up a guitar and play a few tunes, and with a few lessons you play as well as you did before.

Retrieval Retrieval Cues – clues that provide reminders of information that otherwise would be more difficult to remember; clues that can guide us the where to look for the right answers.

Retrieval Priming – the activation of particular associations in memory; this may be done consciously or unconsciously, purposefully or incidentally

Retrieval IE. Mnemonic clues (Roy G Biv) are primers that allow you to remember information many types of factual information IE. A “Missing Child” poster makes you think about your own abduction as a child IE. The color red prompts memories of days on your grandfathers farm, with its big red barn IE. The first letter of each vocabulary word is provided on your test.

Retrieval Cues Context Effects – the tendency to remember information better and more accurately when you are in a physical setting that is similar to the one that you learned the information in the first place

Retrieval Cues Mood-Congruent – along with the state-dependent theory, our moods bias our memories also (we remember things better when we are in the same mood as when the memory was formed) IE. You had a fantastic 5th birthday party, with lots of friends, gifts, clowns, etc. BUT, you had a cold that day and were sad. Your memory of your 5th birthday party may be that it was long, dreary, and sad.

Retrieval Cues State-Dependent Theory – what we learn in one physical state – such as drunk or sober – is sometimes more easily recalled when we are again in that same state

Retrieval Cues déjà vu – “Already Seen” (French) The eerie sense that “I’ve been in this exact situation before” Paranormal Explanation – Precognition or Reincarnation? Memory Explanation – If a situation is loaded with clues that are similar to ones already in memory, your brain makes similar associations between them

Forgetting, Memory Construction, and Improving Memory

Retrieval Failures Repression - a basic defense mechanism that banishes from consciousness anxiety-arousing thoughts, feelings, and memories People can knowingly, or unknowingly, revise their own histories

Retrieval Failures Tip-Of-The-Tongue Experience – the inability to get a bit of information that you’re absolutely certain is stored in your memory – the information is very close, but just out of reach

Medical Memory Loss Amnesia – severe memory loss Retrograde – forget things from the past Anterograde – inability to form new memories but remember the past Alzheimers – as plaques build in the brain and interfere with neural transmissions, memories cannot be formed or retrieved

False Memories Source Confusion – arises when the true source of a memory is forgotten, so you create details to fill in the gaps You actually saw that on tv… Elizabeth Loftus Misinformation Effect – a person’s existing memories can be altered if the person is exposed to misleading information Eyewitness Testimony…How reliable is it?

How To Make Memories Last? A Few Suggestions Focus your attention Commit the necessary time Space your study sessions Organize the information Elaborate on the material

How To Make Memories Last? A Few Suggestions Use visual imagery and other mnemonics Explain it to a friend Reduce Interferences Since we usually remember the early part and the last part, spend extra time on the middle Use contextual clues to jog memory
