Information Processing Module 20
What is Memory? Process of encoding, storage, and retrieval. Learning that persists over time. Encoding • Get info in Storage • Retain the info Retrieval • Getting the information out
In-Class Activity—A Look Into Memory Take out a sheet of paper Write down, in order, all responses that come to mind Ready?
What are the names of the seven dwarfs in the story of Snow White? Don’t ask a friend!
What are the names of the seven dwarfs in the story of Snow White? Difficult? Why? • Never learned the names (encoding) • Length of time (storage) • Distractions (retrieval)
What if you had a list to choose from? 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
What are the names of the seven dwarfs in the story of Snow White? The names… • Sleepy, Dopey, Grumpy, Sneezy, Happy, Doc & Bashful Get more names correct with list? Why? • Recall vs. Recognition
What are the names of the seven dwarfs in the Disney movie Snow White? Feel like you knew a name but couldn’t recall it? Why? • Tip of the tongue phenomenon • Retrieval failure
In-Class Activity – Part 2… Turn your paper over or fold in half Write down the names of the seven dwarfs Easier than before? • Short term memory vs. long term memory
Encoding: Getting Information In Automatic Processing • Time • Space • Frequency • Well-learned material Effortful Processing
Encoding: Getting Information In Effortful Processing Ebbinghaus: Rehearsal & Overlearning
How do we encode? Serial Position Effect
Howdo we encode? Spacing Effect Distributed vs. Cramming Rehearsal Primacy & Recency
What do we encode? Meaningful Information • Personally meaningful • Related to previously learned info Encoded Images • Mental “pictures” • Mnemonics • Kids Please Close Our Front Gate Slowly
What do we encode? OrganizedInformation • Chunking • ROY G BIV • Phone numbers… 867-5309 • Hierarchies
Let’s test your encoding!iclicker question According to the serial position effect, when recalling a list of words you should have the greatest difficulty remembering those: A) at the beginning of the list B) at the end of the list C) in the middle of the list D) at the beginning and the end of the list
iclicker question You are most likely to automatically encode information about: A) Politicians names B) New phone numbers C) What you did before and after you ate breakfast D) What we learn today
Storage: Retaining the Information Working/ Short-term Memory Sensory Memory Long-term Memory Encoding Events Encoding Retrieval Retrieval
Storage- Retaining the Information Sensory Memory Fleeting representation unless we attend Lasts for ~ second Iconic & Echoic
Storage Working/Short-Term Memory 20 secs – couple minutes “Hold” a limited amount of info (7 +/- 2) No active processing = no short-term memories disappear
Storage Long-Term Memory Info stored; can be retrieved Lasts indefinitely Can hold billions of pieces of info
Storage- How do we do it? Synaptic Changes Pathway of neural activation creates a stored memory Path reinforced with use
Storage Stress Hormones Heightened emotions = stronger memories Boosts activity in memory-forming brain areas More replay= stronger connections Can we take a pill for this?
Storage Implicit Memory • Memory for procedures & skill acquisition • Ex: Driving a car • Cerebellum Explicit Memory • Memory for facts & experiences • Ex: Who was your first kiss? • Hippocampus-temporary storage site • Cortex
Retrieval- Getting Information Out 3 Retrieval Types • Recall: generate information • Recognition: identify items • Relearning: learn material for a second time
Retrieval Retrieval Cues: Anchor points used to access the info later
Retrieval Context Effects Remember better if cues present at encoding are present at retrieval
Retrieval Mood-Congruent Memory Recall experiences consistent with current mood
Déjà Vu Familiar situation can trigger feelings of “I’ve been here before”
Another Activity… 2 volunteers 1 with musical knowledge (majors, private lessons) 1 with little musical knowledge
Retrieval & Expertise Expertise Development Central concepts become increasingly elaborated, organized & interconnected
Iclicker Question When 80-year-old Ida looked at her old wedding pictures, she was flooded with vivid memories of the early years of her marriage, which she had not thought about in decades. The pictures served as powerful: A) Encoding cues B) Iconic memories C) Implicit memories D) Retrieval cues
Iclicker Question Memory of facts is to ________ as memory of skills is to ________. A) Brainstem; Hippocampus B) Explicit Memory; Implicit Memory C) Automatic Processing; Effortful Processing D) Short-term Memory; Long-term Memory
So could our memory ever be too good? The women who can’t forget… http://www.youtube.com/watch?v=SoxsMMV538U&feature=related
Mini-writing #9 You have a friend who is struggling in a class. Now that you know so much about memory, identify 2 effects that we have learned about in class that pertain to memory that could help him. Explain each effect and how each effect would improve his test performance. Effortful processing Rehearsal Overlearning Serial position effect Spacing Effect Imagery Meaningfulness Mnemonics Chunking Retrieval Cues Hierarchies Context Effects Sleep
