DO NOW… What is your first memory?
2
Chapter 9 Memory
3
Memory Memory Flashbulb Memory
persistence of learning over time via the storage and retrieval of information Flashbulb Memory a clear memory of an emotionally significant moment or event Example: September 11 What is your first memory? Memory is an indication that learning has persisted over time Flashbulb memories – it’s as if the brain commands you to remember the moment
4
Memory Let’s test your memory:
Take out a sheet of paper and silently write down the names of the seven dwarves in the Disney classic Snow White. Give them time to try it
5
Memory Sneezy Lazy Pop Grumpy Bashful Cheerful Teach Shorty Nifty
Grouchy Gabby Fearful Sleepy Smiley Jumpy Hopeful Shy Droopy Dopey Sniffy Wishful Puffy Dumpy Sneezy Lazy Pop Grumpy Bashful Cheerful Teach Shorty Nifty Happy Doc Wheezy Stubby Now see if you can pick out the seven dwarves
6
Snow White and the Seven Dwarfs
Dopey, Grumpy, Doc, Happy, Bashful, Sneezy, Sleepy Check yourselves – recognition is easier than recalling from memory
7
Memory Memory as Information Processing Encoding similar to a computer
write to file save to disk read from disk Encoding the processing of information into the memory system
8
Memory Storage Retrieval
the retention of encoded information over time Retrieval process of getting information out of memory Limitations of computer analogy: our memories are less literal and more fragile than a computer’s The brain is slower than a computer, but it can do many things at once (with regards to recall)
9
Types of Memory Sensory Memory Short Term Memory Long Term Memory
the immediate, initial recording of sensory information in the memory system Iconic a momentary sensory memory of visual stimuli a photographic or picture image memory lasting no more that a few tenths of a second Registration of exact representation of a scene Echoic Memory momentary sensory memory of auditory stimuli Short Term Memory activated memory that holds a few (7 +/- 2) items briefly Long Term Memory the relatively permanent and limitless storehouse of the memory system Sensory is the first step, it is fleeting The next step is that things we want to remember temporarily are stored in short-term memory (like a phone number you repeat again and again until you call it) Lastly, you encode it for long-term memory and later retrival
11
Sensory memory (Iconic)
What was in the scene?
12
The Atkinson Shiffrin Model
External events Sensory memory Short-term Long-term Sensory input Attention to important or novel information Encoding Retrieving
13
Check for Understanding
Many people have vivid memories of highly emotional moments – for example, when they heard the news of an assassination or what kind of morning it was when they brought the new baby home from the hospital. These clear memories of emotional moments are called Short-term memories Flashbulb memories Inaccurate memories Novel memories
14
Encoding Automatic Processing Effortful Processing
unconscious encoding of incidental information well-learned information word meanings we can learn automatic processing Effortful Processing requires attention and conscious effort
15
Ways to Encode Rehearsal conscious repetition of information
to maintain it in consciousness to encode it for storage German philosopher Herman Ebbinghaus used nonsense syllables TUV ZOF GEK WAV the more times practiced on Day 1, the fewer repetitions to relearn on Day 2 The amount remembered depends on the time spent learning.
16
Ways to Encode Spacing Effect Primacy/Recency (Serial Position Effect)
distributed practice yields better long term retention than massed practice Primacy/Recency (Serial Position Effect) Example: US Presidents
17
The three stages of the Atkinson-shiffrin process of memory are:
(A) iconic, echoic, encoding (B) sensory, short term, long term (C) shallow, medium, and deep processing (D) semantic, episodic, procedural
18
(C) apples, pears, bananas (D) peas, corn, onions
Doug wrote a grocery list of 10 items but leaves it at home. The list included in order: peas, corn, squash, onions, apples, pears, bananas, flour, milk, and eggs. If the law of primacy holds, which of the following is doug most likely to remember? (A) peas, pears, flour (B) banana, flour, peas (C) apples, pears, bananas (D) peas, corn, onions

WORD Poster Include the following: Definition Significance Image
Use it in a sentence Related words
20
DO NOW… Differentiate between effortful and automatic encoding.
21
Ways to Encode Hierarchies Imagery Mnemonics Chunking Use of Acronyms
Outlines Imagery Mental pictures a powerful aid to effortful processing, especially when combined with semantic encoding Mnemonics memory aids especially those techniques that use vivid imagery and organizational devices Method of Loci (Greek drama) Chunking Organize information into meaningful units; helps us with unfamiliar meaning Like horizontal organization – Often occurs automatically Use of Acronyms HOMES – Huron, Ontario, Michigan, Erie, Superior Socks Pulled On Cold Feet – Sensorimotor, Preoperational, …
22
Storage- Long Term Memory Subsystems
Types of long-term memories Explicit (declarative) With conscious recall Implicit (nondeclarative) Without conscious Facts-general knowledge (“semantic memory”) Personally experienced events (“episodic Skills-motor and cognitive Conditioning effects
23
Retrieval Relearning amount of time saved when relearning previously learned information Priming activation, often unconsciously, of particular associations in memory Reminders of information we could not otherwise recall Guides to where to look for info Context Effects memory works better in the context of original learning
24
Forgetting Information never enters the memory system
Forgetting as Encoding Failure Information never enters the memory system Attention is selective we cannot attend to everything in our environment
25
Forgetting as Interference
Learning some items may disrupt retrieval of other information Proactive(forward acting) Interference disruptive effect of prior learning on recall of new information Example: Retroactive (backwards acting) Interference disruptive effect of new learning on recall of old information
26
Forgetting as Interference
27
Memory Construction Eyewitnesses reconstruct memories when questioned
Depiction of actual accident Leading question: “About how fast were the cars going when they smashed into each other?” Memory construction Eyewitnesses reconstruct memories when questioned
