3. Module 31 – Studying and Building Memory
SWBAT describe information processing as relates to memory and encoding processes

4. Memory Memory The extremes of memory:
The persistence of learning over time
The extremes of memory:
Some individuals suffer from incredible short-term memory loss: they are unable to make new memories or even remember what day of the week it is
Others are incredibly capable of remembering
Russian journalist Shereshevskii was able to remember more than 70 digits or words spoken to him in a silent room (you or I might be able to remember 7-9)
The current world record holder for memorized digits of Pi is Chao Lu of China at 67,890 digits
Dominic O’Brien of the UK memorized 54 decks of cards (2808 cards)
Ben Pridmore of the UK memorized a single shuffled deck of cards in under 30 seconds

5. Memory In order to truly remember any event, we must (like computers):
Encoding: getting information into our brains
Storage: retaining that information
Retrieval: getting that information back out
We also typically perform parallel processing, unlike computers, where we process information about people you see, voices you hear, and food you smell at once.

6. Models of Memory Atkinson & Shiffren model:
We record to-be-remembered information as a fleeting sensory memory
We process information into short-term memory, activated memory that holds few items briefly before the information is stored or forgotten
Information moves into long-term memory, the relatively permanent and limitless storehouse of information, skills, and experiences

7. Models of Memory Working memory model Alan Baddeley model
The memory process is ALWAYS active, involving rehearsal of info in short-term and recall from long-term

8. Working Memory and the Central Executive

9. Encoding: Dual-Track Memory
You process a LOT of information at once, and encode it one of two ways:
Explicit memory
Also known as declarative memory, memory of facts and experiences that one can consciously know and declare
Uses effortful processing
Encoding that requires conscious attention and effort
Implicit Memory
Memory that is independent of conscious recollection
Uses automatic processing
Processing that occurs automatically (like the time, space around you, or frequency of event
Involved in latent learning and making cognitive maps

10. Sensory Memory
EXTREMELY brief recording of nearly all sensory data in memory
Iconic memory
A fleeting sensory memory of visual stimuli – a photographic or “perfect” image memory lasting only a few seconds
Echoic memory
A momentary sensory memory of auditory stimuli – if attention is elsewhere, sounds and words can still be recalled for 3 or 4 seconds

11. Capacity of Short Term Memory
Let’s see how much you can remember in the short term.
Magic number 7
Most people can remember roughly seven numbers, digits, or items for a brief period of time in their short term memory
(seven plus or minus 2, so most people can remember between 5 and 9)

12. How You Process With Effort
Chunking
Organizing information into meaningful, familiar units
Let’s try!

13. How You Process With Effort
Mnemonics
Memory aids, such as techniques that use vivid imagery and organizational devices to help remember things
Examples:
ROY G BIV
Colors of the rainbow: Red, Orange, Yellow, Green, Blue, Indigo, Violet
HOMES
Names of the North American Great Lakes: Huron, Ontario, Michigan, Erie, and Superior

15. How You Process With Effort
Hierarchies
Stacks of information subdivided by area and focus

16. How You Process With Effort
Overlearning
Cramming and re-reading simply overload your brain with information. It’s pretty much as bad as not studying – you’ll remember about 20% of the content if you only read it the night before.
Spacing effect
Distributed practice – the longer the spaces between info you study, the longer you will remember it (study it tomorrow to remember it 10 days from now, study it a month from now to remember it for 6 months)
Testing effect
Memory is enhanced after retrieving the info, rather than rereading (like exit tickets or quizzes!)

17. Levels of Processing Shallow Processing Deep Processing
Encoding on a basic level – such as the structure or appearance of words
Deep Processing
Encoding semantically (meaning), based on the meaning of words
Based on this, if new information is not meaningful, we will struggle to remember it.
We especially remember information when it relates to us.
