MemoryMemory:
persistence of learning over time via the storage and retrieval of information.
Gives us our sense of self and connects us to past experiences.

What are your three most vivid memories?
![Page 5: Chapter 9: Memory](https://reader035.vdocument.in/reader035/viewer/2022062520/568164fd550346895dd76a7e/html5/thumbnails/5.jpg)
Vivid MemoriesFlashbulb Memories: clear memory of an emotionally significant event or moment.
Usually personally meaningful or historically significant.
![Page 6: Chapter 9: Memory](https://reader035.vdocument.in/reader035/viewer/2022062520/568164fd550346895dd76a7e/html5/thumbnails/6.jpg)
Episodic Memory: refers to your specific memory of events that occur in your life.
Types of Memories

Types of MemoriesSemantic Memory: General knowledge – facts you learn at school.
![Page 8: Chapter 9: Memory](https://reader035.vdocument.in/reader035/viewer/2022062520/568164fd550346895dd76a7e/html5/thumbnails/8.jpg)
Types of MemoriesImplicit Memory: The skills you have
learned

The Curious Case ofClive Wearing
Why does Clive have such severe memory loss?
What are some of his daily habits?
What did you notice that is interesting about his memoryloss? (hint…think his wife and his profession)
What is Clive’s reaction to his wife’s questions about hisjournal?
Which type of memory is MOST intact?
![Page 10: Chapter 9: Memory](https://reader035.vdocument.in/reader035/viewer/2022062520/568164fd550346895dd76a7e/html5/thumbnails/10.jpg)
Memory as Information Processing
Memory is similar to a computer (write to file, save to disk, read from disk).
3 Basic Steps to Memory: 1. Encoding: getting information into
the memory system.2. Storage: the retention of the
encoded information over time.3. Retrieval: process of getting
information out of the memory system.
![Page 11: Chapter 9: Memory](https://reader035.vdocument.in/reader035/viewer/2022062520/568164fd550346895dd76a7e/html5/thumbnails/11.jpg)
Three Stage Processing for Encoding
Stage One: The initial recording of sensory information in the memory system is referred to as sensory memory.
Stage Two: sensory memories are processed into short term memory your activated memory which can only hold a minimal amount of information.
Stage Three: short term memories are encoded into long-term memory, the relatively permanent and limitless storehouse from which we retrieve.
![Page 12: Chapter 9: Memory](https://reader035.vdocument.in/reader035/viewer/2022062520/568164fd550346895dd76a7e/html5/thumbnails/12.jpg)
![Page 13: Chapter 9: Memory](https://reader035.vdocument.in/reader035/viewer/2022062520/568164fd550346895dd76a7e/html5/thumbnails/13.jpg)
Concept of Short-Term Memory
Short-Term Memory is limited in capacity and duration.
You can only hold so much information in your working memory at one given time.
Magic Number tends to be 7 +/- 2.
![Page 14: Chapter 9: Memory](https://reader035.vdocument.in/reader035/viewer/2022062520/568164fd550346895dd76a7e/html5/thumbnails/14.jpg)
Take 30 seconds to memorize this list of
letters:OTTFFSSENT

Types of EncodingSemantic Encoding: encoding
of meaning, including the meaning of words….yields best memory.
Acoustic Encoding: the encoding of sound, especially the sound of words….usually the least effective.
Visual Encoding: the encoding of picture images.
![Page 16: Chapter 9: Memory](https://reader035.vdocument.in/reader035/viewer/2022062520/568164fd550346895dd76a7e/html5/thumbnails/16.jpg)
Encoding ImageryImagery: creating mental pictures,
helps effortful processing especially when combined with semantic encoding.
Recall of events is often colored by highest joys and lowest lows of events…usually remember events differently than you evaluated them at the time.
Mneumonics: memory aids, often use vivid imagery and organizational devices.

Types of RehearsalMaintenance rehearsal: simple rote
repetition of information in consciousness or;Short term memory
even more successfully by elaborate rehearsal: processing of information by relating it to something you already know well.Long term memory
![Page 20: Chapter 9: Memory](https://reader035.vdocument.in/reader035/viewer/2022062520/568164fd550346895dd76a7e/html5/thumbnails/20.jpg)
The Presidents On a sheet of paper, list the Presidents
of the United States in order. Do your best.
Maintenance rehearsal vs. elaborate rehearsal
![Page 21: Chapter 9: Memory](https://reader035.vdocument.in/reader035/viewer/2022062520/568164fd550346895dd76a7e/html5/thumbnails/21.jpg)
King of Memory Experiments is Hermann Ebbinghaus
Wanted to research capacity of verbal memory.
Looked to study to see capacity of peoples’ memories to study strings of non-sense syllables.
Ex: JIH, FUB, YOX, XIR,
![Page 22: Chapter 9: Memory](https://reader035.vdocument.in/reader035/viewer/2022062520/568164fd550346895dd76a7e/html5/thumbnails/22.jpg)
Findings of Ebbinghaus1. Practice makes perfect. The
more rehearsal he did on day 1, the less rehearsal it took to learn the syllables again on day 2. Over learning increased retention.
2. The Spacing Effect: the tendency for studying over a long period of time produces better long term retention than is achieved through massed study or practice. SPACED STUDYING BEATS CRAMMING!!!
![Page 23: Chapter 9: Memory](https://reader035.vdocument.in/reader035/viewer/2022062520/568164fd550346895dd76a7e/html5/thumbnails/23.jpg)
Findings of Ebbinghaus3. Serial Position Effect: our tendency
to recall best the last and first items in a list. Ex: Presidents
![Page 24: Chapter 9: Memory](https://reader035.vdocument.in/reader035/viewer/2022062520/568164fd550346895dd76a7e/html5/thumbnails/24.jpg)
Explaining the Serial Position Effect
Primacy Effect: explains how we remember concepts at the beginning of a list since these are often the terms we have seen the most when reviewing.
Recency Effect: explains how we remember concepts at the end of the list a since these are the terms we have seen most RECENTLY.
MIDDLE IS FORGOTTEN MOST OFTEN.
![Page 25: Chapter 9: Memory](https://reader035.vdocument.in/reader035/viewer/2022062520/568164fd550346895dd76a7e/html5/thumbnails/25.jpg)
Encoding Activity (Myers 9-3)
Follow the instructions on the handout as I read the 20 sentences. It is important that you do not talk or communicate with anyone else during this activity.
![Page 26: Chapter 9: Memory](https://reader035.vdocument.in/reader035/viewer/2022062520/568164fd550346895dd76a7e/html5/thumbnails/26.jpg)
Some Examples of Mneumonics
1. Method of Loci: memory device used by linking items in a list with physical locations in a place you are familiar with. Ex: Link parts of brain with places in your house; Hypothalamus and refrigerator.
2. Peg Word System: works by prememorizing a list of words with numbers and associating new list with the scheme. Ex: 1 is a gun, 2 is a zoo, 3 is a tree, 4 is a door, 5 is a hive.

Retrieval: Getting Information Out
Recall: a measure of memory in which the person must retrieve information learned earlier.Ex: Fill in the Blank.
The hardest of the memory tasks
![Page 64: Chapter 9: Memory](https://reader035.vdocument.in/reader035/viewer/2022062520/568164fd550346895dd76a7e/html5/thumbnails/64.jpg)
Retrieval: Getting Information Out
Recognition: a measure of memory in which the person need only identify items previously learned.Ex: Multiple Choice
The easiest of the three memory tasks
![Page 65: Chapter 9: Memory](https://reader035.vdocument.in/reader035/viewer/2022062520/568164fd550346895dd76a7e/html5/thumbnails/65.jpg)
Retrieval: Getting Information Out
Relearning: learning something for the second (or third or fourth or …) time.
Relearning an idea or concept happens more quickly than learning something the first time.

Storage Loss: AmnesiaAmnesia refers to the
loss of memory.Amnesiac patients
typically have losses in explicit memory.
![Page 71: Chapter 9: Memory](https://reader035.vdocument.in/reader035/viewer/2022062520/568164fd550346895dd76a7e/html5/thumbnails/71.jpg)
Types of Amnesia Anterograde Amnesia: type of memory loss
where patients are UNABLE TO FORM ANY NEW MEMORIES. Can’t remember anything that has occurred AFTER a traumatic head injury.
Retrograde Amnesia: type of memory loss where patients are UNABLE TO REMEMBER PAST EVENTS. May forget everything that happened BEFORE a traumatic head injury.
Infantile Amnesia

Motivated Forgetting As A Freudian Concept
Repression: idea put forth by psychoanalytic theorists like Freud which states anxiety arousing thoughts, feelings, and memories can be banished from consciousness.
Ex: child abuse, rape, incest may be repressed and not be able to be actively recalled.
![Page 74: Chapter 9: Memory](https://reader035.vdocument.in/reader035/viewer/2022062520/568164fd550346895dd76a7e/html5/thumbnails/74.jpg)
Freud believed Repression was a Defense Mechanism
Freud argued individuals often “forgot” traumatic incidents to protect their self concepts and to minimize external anxiety.
Freud argued “Forgotten” incidents are banished the “unconscious.”
The incidents may cause you to have unexplained phobias or problems, that wont be helped until you uncover the incident.

Retrieval Cues Context Effects Memory Retrieval: able
to retrieve information better when you are in the same context you learned it in. Ex. Studying for a test in the same room you are
going to take the test in.
Emotional/Mood Impact of Memory: State-Dependent Memory: information is
most easily recalled when in same “state” of consciousness or mood it was learned in.
Ex. Under the influence of drugs or alcohol. Feelings of happiness tend to bring back memories of
another happy time.

Loftus’s ResearchSubjects were asked to reveal how fast
they thought the cars were going.Question consisted of “How fast were the
cars going when they _______________ each other.
Loftus filled in the blanks with different words including: bumped, collided, contacted, hit, or smash.
Speed was elevated to great degree when “smashed” was used as key verb and subjects were likely to remember broken glass when there was none.
