How difficult or easy was this for you?
In order to name the 7 dwarfs, your brain went through the following process:◦Encoding: learning the information◦Retaining: storing the information over time
◦Retrieval: getting the information back out

Did you have a feeling that you knew the name of a dwarf but were unable to retrieve it?◦This is called Tip-of-the-Tongue Phenomenon: when the retrieval process does not produce a complete response but produces parts that must be constructed into a whole
Shows that forgetting may result from retrieval failure, not encoding or storage failures

Look at the order in which you wrote down the names, is there any pattern?Memory is organized by sound, letter, or meaning

How many think they would do better if they saw pictures of the dwarfs?◦Recall vs. Recognition Recognition is generally easier b/c the first step is already complete & all you have to do is decide if the information is correct

Circle correct dwarf namesCross out incorrect namesLeave alone ones you are unsure of
Were we able to remember more correct names this way?

Memory: the persistence of learning over time through the storage and retrieval of information
Memory = basis for knowing your friends, neighbors, English, the national anthem, and yourself
If memory was nonexistent, everyone would be a stranger to you; every language foreign; every task new; & even you yourself would be a stranger.

Write down a sentence or two about your 3 most vivid memories
Almost all of what you wrote down was probably of a personally, rather than nationally, important nature:
◦Injury/accident (18%)◦Sports (11%)◦Attraction (10%)◦Animals (9%)◦Deaths (5%)◦Vacations (5%)

A unique and highly emotional moment may give rise to a clear, strong, and persistent memory called flashbulb memory
However, thismemory is notfree from errors
Flashbulb Memory
![Page 14: 11.23.15. The Phenomenon of Memory In your notes, WITHOUT talking to anyone, write down the names of the 7 dwarfs from Snow White and the Seven Dwarfs](https://reader036.vdocuments.mx/reader036/viewer/2022081515/5a4d1b227f8b9ab059995e0b/html5/thumbnails/14.jpg)
Why can flashbulb memories be wrong?
How can we remember things we haven’t thought about for 4 years but forget the name of a person we just met a minute ago?
How can 2 people’s memories of the same event be different?
How can we improve our memories?

Without writing it down, try to remember this sentence:◦The angry rioter threw the rock at the window.

Information ProcessingThe Atkinson-Schiffrin (1968) 3-
stage model of memory:1. sensory memory2. short-term memory3. long-term memory

Problems with the Model1. Some info skips the first 2 stages &
enters long-term memory automatically
2. Since we can’t focus on all sensory info in the environment, we select info (through attention) that is important to us
3. The nature of short-term memory is more complex
![Page 20: 11.23.15. The Phenomenon of Memory In your notes, WITHOUT talking to anyone, write down the names of the 7 dwarfs from Snow White and the Seven Dwarfs](https://reader036.vdocuments.mx/reader036/viewer/2022081515/5a4d1b227f8b9ab059995e0b/html5/thumbnails/20.jpg)
Working memory: newer understanding of short-term memory; involves conscious, active processing of incoming auditory & visual-spatial info, and of info retrieved from long-term memory◦Incoming stimuli, along with info from our long-term memory, becomes conscious short-term memories in a temporary “construction zone”

Working MemoryAuditory & visual processing is controlled by a central executive, through an episodic buffer
![Page 22: 11.23.15. The Phenomenon of Memory In your notes, WITHOUT talking to anyone, write down the names of the 7 dwarfs from Snow White and the Seven Dwarfs](https://reader036.vdocuments.mx/reader036/viewer/2022081515/5a4d1b227f8b9ab059995e0b/html5/thumbnails/22.jpg)
Brain activity underlies these working memory components◦Frontal lobes are active when central executive focuses on complex thinking
◦Parietal & Temporal lobes that help us process auditory & visual info are active when such info is in our working memory
