3 Kinds of Memory
Episodic Memory
Semantic Memory
Implicit Memory
![Page 4: Chapter 7 - Memory Psychology McGonigle- College Prep/ Honors](https://reader036.vdocuments.us/reader036/viewer/2022062308/56649e625503460f94b5d78d/html5/thumbnails/4.jpg)
Episodic Memory
Memory of a specific event, event took place in the person’s presence, or the person experienced the event.
Flashbulb memory: Event that is so important it seems like we photograph it in every detail.
![Page 5: Chapter 7 - Memory Psychology McGonigle- College Prep/ Honors](https://reader036.vdocuments.us/reader036/viewer/2022062308/56649e625503460f94b5d78d/html5/thumbnails/5.jpg)
Semantic Memory
We remember general knowledge such as who is the first president of the United States. (George Washington)
Unlike flashbulb, we don’t remember when we first learned that Washington was the first President.
Episodic & Semantic are both known as Explicit memories. This means that are clearly stated & defined.
![Page 6: Chapter 7 - Memory Psychology McGonigle- College Prep/ Honors](https://reader036.vdocuments.us/reader036/viewer/2022062308/56649e625503460f94b5d78d/html5/thumbnails/6.jpg)
Implicit Memory
Opposite of Explicit memory
Implied or not clearly stated memories are implicit.
Swimming, skipping rope, riding a bike, playing an instrument, driving a car.

Encoding
Translation of information into a form in which it can be stored.
When one places information into their memory, they like computers, encode it.
Encoding- for the computer & the human brain, it is the first stage of processing information.
![Page 8: Chapter 7 - Memory Psychology McGonigle- College Prep/ Honors](https://reader036.vdocuments.us/reader036/viewer/2022062308/56649e625503460f94b5d78d/html5/thumbnails/8.jpg)
Visual Codes
Try to memorize a set of letters by seeing them in your mind as a picture.
Try to form a mental picture of OTTFFSSENT in your head to memorize the first ten numbers.
![Page 9: Chapter 7 - Memory Psychology McGonigle- College Prep/ Honors](https://reader036.vdocuments.us/reader036/viewer/2022062308/56649e625503460f94b5d78d/html5/thumbnails/9.jpg)
Semantic CodesMethod of Remembering
Semantic- Attempt to make sense of the letters- figure out what they might mean.
Semantic Codes: “ Mary’s violet eyes make John stay up nights.”
Remember : Roy G Biv , Musical scales “Every good boy deserve fudge”
![Page 10: Chapter 7 - Memory Psychology McGonigle- College Prep/ Honors](https://reader036.vdocuments.us/reader036/viewer/2022062308/56649e625503460f94b5d78d/html5/thumbnails/10.jpg)
Storage of memory
Storage – Maintenance of encoded information over a period of time.
Human storage – of information is not all that different from a computer’s storage of information.
To save information- one must use a variety of strategies.
![Page 11: Chapter 7 - Memory Psychology McGonigle- College Prep/ Honors](https://reader036.vdocuments.us/reader036/viewer/2022062308/56649e625503460f94b5d78d/html5/thumbnails/11.jpg)
Maintenance Rehearsal
Repeating information over and over again to keep from forgetting.
Actors + actresses: repeat their lines again.
MR: Does not make info meaningful, it is poor for permanent storage.
![Page 12: Chapter 7 - Memory Psychology McGonigle- College Prep/ Honors](https://reader036.vdocuments.us/reader036/viewer/2022062308/56649e625503460f94b5d78d/html5/thumbnails/12.jpg)
Elaborative Rehearsal
New and effective way to remember new information is to make it meaningful by relating it to info that you already know.
Language arts and foreign language- use new words in sentences instead of just repeating words by themselves.
![Page 13: Chapter 7 - Memory Psychology McGonigle- College Prep/ Honors](https://reader036.vdocuments.us/reader036/viewer/2022062308/56649e625503460f94b5d78d/html5/thumbnails/13.jpg)
Organizational Systems
As memory develops, it organizes info into files, and then files within files.
Memory organizes into certain groups or classes according to common features.
( Presidents – 20s, 30s, 40s)
![Page 14: Chapter 7 - Memory Psychology McGonigle- College Prep/ Honors](https://reader036.vdocuments.us/reader036/viewer/2022062308/56649e625503460f94b5d78d/html5/thumbnails/14.jpg)
Filing Errors for Memory
Ability to remember info is subject to error.
Memory errors occur, because we file information incorrectly.
Place piece of info in the wrong folder, like a science paper in a math folder.
![Page 15: Chapter 7 - Memory Psychology McGonigle- College Prep/ Honors](https://reader036.vdocuments.us/reader036/viewer/2022062308/56649e625503460f94b5d78d/html5/thumbnails/15.jpg)
Retrieval
Consists of locating stored information and returning it to conscious thought.
Retrieving information stored in our memory is like retrieving information stored in a computer.
For fun: How can you remember how to spell retrieval? Quick – name all 8 planets !!!!!
![Page 16: Chapter 7 - Memory Psychology McGonigle- College Prep/ Honors](https://reader036.vdocuments.us/reader036/viewer/2022062308/56649e625503460f94b5d78d/html5/thumbnails/16.jpg)
Context Dependent Memory
Have you ever visited your old house, school or baseball/softball diamond?
Memories that came back to you were CDMs, the situation in which the person first had this experience.
Students – perform better on a test when they study in the room where the test will be given. (scene of the crime memories)
![Page 17: Chapter 7 - Memory Psychology McGonigle- College Prep/ Honors](https://reader036.vdocuments.us/reader036/viewer/2022062308/56649e625503460f94b5d78d/html5/thumbnails/17.jpg)
State Dependent Memories
It is easier to retrieve memories when we are in the same emotional state we were in when first stored.
Feelings of happiness- tend to bring back memories of times when we were happy, vice versa with sad memories.
![Page 18: Chapter 7 - Memory Psychology McGonigle- College Prep/ Honors](https://reader036.vdocuments.us/reader036/viewer/2022062308/56649e625503460f94b5d78d/html5/thumbnails/18.jpg)
Tip of the Tongue Phenomena
You are sure you know something, you just can’t verbalize it.
“Feeling of Knowing” experience.
We use acoustic or semantic cues to help us remember. ( similar in sound or meaning)
![Page 19: Chapter 7 - Memory Psychology McGonigle- College Prep/ Honors](https://reader036.vdocuments.us/reader036/viewer/2022062308/56649e625503460f94b5d78d/html5/thumbnails/19.jpg)
Sensory Memory
1st stage of memory- immediate recording of info that enters through our senses/
Visual stimuli- decays within seconds.
Want to remember- do something with it (stimuli) quickly.
![Page 20: Chapter 7 - Memory Psychology McGonigle- College Prep/ Honors](https://reader036.vdocuments.us/reader036/viewer/2022062308/56649e625503460f94b5d78d/html5/thumbnails/20.jpg)
Iconic Memory
Icons- mental pictures we form of visual stimuli.
Icons- held in a sensory register called iconic memory.
Iconic memories- Are like snapshots, however they are extremely brief- just a fraction of a second. (subliminal)
![Page 21: Chapter 7 - Memory Psychology McGonigle- College Prep/ Honors](https://reader036.vdocuments.us/reader036/viewer/2022062308/56649e625503460f94b5d78d/html5/thumbnails/21.jpg)
Eidetic Memory
Ability to remember visual stimuli over a long period of time.
This is what is known as photographic memory.
5 % of children have photographic memory.
![Page 22: Chapter 7 - Memory Psychology McGonigle- College Prep/ Honors](https://reader036.vdocuments.us/reader036/viewer/2022062308/56649e625503460f94b5d78d/html5/thumbnails/22.jpg)
Echoic Memory
Echoes- mental traces of sounds.
Echoes- are held in a sensory register called echoic memory.
Acoustic codes are easier to remember than visual codes. (example)
![Page 23: Chapter 7 - Memory Psychology McGonigle- College Prep/ Honors](https://reader036.vdocuments.us/reader036/viewer/2022062308/56649e625503460f94b5d78d/html5/thumbnails/23.jpg)
Short Term Memory Also called- working Memory Meeting new people Math problems Due dates for HW + papers Remembering phone numbers
Info- fades rapidly. Need to take steps to prevent from fading. 7 digit phone #s.
![Page 24: Chapter 7 - Memory Psychology McGonigle- College Prep/ Honors](https://reader036.vdocuments.us/reader036/viewer/2022062308/56649e625503460f94b5d78d/html5/thumbnails/24.jpg)
Primacy Effect
Tendency to recall the initial items in a series of items.
We remember the 1st few items of a series better because of their placement earlier in the list.
![Page 25: Chapter 7 - Memory Psychology McGonigle- College Prep/ Honors](https://reader036.vdocuments.us/reader036/viewer/2022062308/56649e625503460f94b5d78d/html5/thumbnails/25.jpg)
Recency Effect
The tendency to recall the last items in a list = recency effect.
Last items- rehearsed and perceived most recently.
Are still fresh in your mind & rehearsed most recently.
![Page 26: Chapter 7 - Memory Psychology McGonigle- College Prep/ Honors](https://reader036.vdocuments.us/reader036/viewer/2022062308/56649e625503460f94b5d78d/html5/thumbnails/26.jpg)
