Sensory Memory: filter
•Perception
•Attention
•Pattern Recognition
•Meaning Making
Sensory Memory
• Brief/fleeting storage (seconds) of incoming information
• Iconic (visual) for .5 seconds (7-9?)• Echo (auditory) for 4 seconds (5-7)?
04/13/23 Dr. A. Hadwin 7
Improving Sensory Memory
• Increase Attention Available» Clear your head of distractors
• Decrease Attention Required» Prepare the environment E.g. turn the TV off
• Attend to only the most important information
» Strategically attend
04/13/23 Dr. A. Hadwin 8
What does that mean for instructional design?
• Use signals• Make purpose clear• Draw on multiple senses• Arouse curiosity• Prompt metacognitive monitoring and control
of attention…questions and answers
04/13/23 Dr. A. Hadwin 9
Working Memory
04/13/23 Dr. A. Hadwin 10
Where the work happens
•Holding
•Rehearsing
•Encoding
Example of WM in action
• Read each sentence out loud• Remember the last word of each sentence• Don’t write anything down
04/13/23 Dr. A. Hadwin 11
The rain and howling wind kept beating against the rattling window panes.
04/13/23 Dr. A. Hadwin 12
He covered his heart with both hands to keep anyone from hearing the noise it made.
04/13/23 Dr. A. Hadwin 13
The stories all deal with a middle aged protagonist who attempts to withdraw from society.
04/13/23 Dr. A. Hadwin 14
Without tension there could be no balance either in nature or in mechanical design.
04/13/23 Dr. A. Hadwin 15
In a flash of fatique and fantasy, he saw a fat monster sitting beside a campfire.
04/13/23 Dr. A. Hadwin 16
The lieutenant sat beside the man with the walkie-talkie and stared at the muddy ground.
04/13/23 Dr. A. Hadwin 17
What was the last word in each sentence?
04/13/23 Dr. A. Hadwin 18
Last word
• Panes• Made• Society• Design• Campfire• Ground
04/13/23 Dr. A. Hadwin 19
Now what if I asked you to:
Read the sentences and tell me whether they were true or false
• AND
Remember the last word of each sentence?
04/13/23 Dr. A. Hadwin 20
Working Memory Capacity
• Limited (7 + or - 2) items or chunks
• Constrained by amount and depth of processing required…when the information is easier, can hold more, when the information is difficult, can hold less.
04/13/23 Dr. A. Hadwin 21
Think of Working Memory as…
• Ram in your computer
• Spinning plates
04/13/23 Dr. A. Hadwin 22
In working memory you try to:
• Rehearse (maintenance rehearsal)
• Connect with what you know (elaborative rehearsal)
04/13/23 Dr. A. Hadwin 23
Working memory constrained by:
04/13/23 Dr. A. Hadwin 24
What you have to process
-information load-similarity of items-number of items processed during subsequent activities-passage of time
How you have to process, rehearse & assemble
-chunking-clustering-mnemonics-coding
Why is information lost from working memory?
• Cognitive overload
• Lack of strategies for allocating resources
• Too much at a time with too much complexity combined…..studies of cognitive load
04/13/23 Dr. A. Hadwin 25
Strategies
• Consider cognitive load of environment - can off load some work to external resources
• Teach strategies for processing info or optimizing working memory
– Chunking information– Pacing, selecting key points
• Pre-train or develop automaticity• Activate relevant prior knowledge (frameworks for
making sense of new info)
04/13/23 Dr. A. Hadwin 26
Long Term Memory
04/13/23 Dr. A. Hadwin 27
•Like a human hard drive
•Permanent storage
•Unlimited storage
•Unlimited duration
04/13/23 Dr. A. Hadwin 28
Long Term Memory
Semantic Episodic Productions
Scripts
Concepts
Propositions
Schemata
Declarative knowledge(knowing what)
Procedural knowledge (knowing how)
Conditional knowledge (knowing when & why)
Declarative knowledge : WHAT
• Semantic
• Concepts & principles
• Episodic
• Experiences
04/13/23 Dr. A. Hadwin 29
How is information organized and held in LTM?
• Multiple theories to explain this:
• Concepts and prototypes• Propositional networks• Schemata
04/13/23 Dr. A. Hadwin 30
Schemata
• Information organized into key ideas (slots)• Activated when enough requisite values are
present
04/13/23 Dr. A. Hadwin 31
04/13/23 Dr. A. Hadwin 32
Contents of memory consists of representations not exact copies
Encoding varies depending upon the schemata that were activated
Recall is reconstructive, schemata provide frameworks for recall
Recall involves re-creating information and events
Activity
04/13/23 Dr. A. Hadwin 33
Activity
• Find a partner• One of you close your eyes• Other person, read the following statement to
yourself (NOT OUT LOUD).
04/13/23 Dr. A. Hadwin 34
The following passage is about:
Doing Laundry
04/13/23 Dr. A. Hadwin 35
This procedure is actually quite simple. Firstyou arrange items into different groups. Ofcourse one pile may be sufficient dependingon how much there is to do. If you have togo somewhere else due to lack of facilitiesthat is the next step; otherwise, you arepretty well set. It is important not to overdothings. That is, it is better to do too fewthings at once than too many. In the shortrun this may not seem important butcomplications can easily arise. A mistakecan be expensive as well. At first, the wholeprocedure will seem complicated. Soon,however, it will become just another facet oflife. It is difficult to foresee any end to thenecessity for this task in the immediatefuture, but then, one never can tell. After theprocedure is completed one arranges thematerials into different groups again. Thenthey can be put into their appropriateplaces. Eventually they will be used oncemore and the whole cycle will then have tobe repeated. However, that is part of life.
Write everything you remember
04/13/23 Dr. A. Hadwin 36
•Compare with your partner
•Simple procedure•Arrange items in groups (perhaps 1 pile)•May go somewhere else due to lack of facilities •Do not overdo things. •better to do too few things at once than too many•Otherwise complications can easily arise. •Mistakes are expensive •Complicated at first, becomes regular facet of life•Not likely an end to the necessity for this task •arranges the materials into different groups again. •put into their appropriate places. •Repeat•Just part of life
Who remembered more?
Differences in what you remembered?Why?
If I tell you this is about doing laundry…
• You will activate the relevant schema first• Direct attention to information based on that schema• Select and encode what is relevant• Ultimately remember more • (Bransford & Johnson, 1972).

Learning like Puzzles
04/13/23 Dr. A. Hadwin 38
Learning/processing involves
04/13/23 Dr. A. Hadwin 39
Encoding
Storage
Retrieval
transferring information from STM to LTM
holding info in LTM in an organized fashion
Finding info in LTM & transferring to STM
SMART learning
S = Search and select
M = Monitor
A = Assemble – make connections
R = Rehearse
T = Translate
04/13/23 Dr. A. Hadwin 40
Need to practice retrieval too.
• Encoding and using multiple encoding strategies is important
• BUT
• It is just as important that you practice retrieving information in multiple ways….particularly those similar to the ways you will USE information
04/13/23 Dr. A. Hadwin 41
What is rehearsal?
• Revisiting the to-be-learned material multiple times (repetition)
• Rereading
• Reworking the to-be-learned-material to help encode it in long term memory
• Retrieving information from memory to see what you remember and how you remember it.
04/13/23 Dr. A. Hadwin 42
Timing of learning
• Which his better?• reviewing in large solid chunks of time (massed practice)• OR• shorter more focused learning sessions repeated over time
(distributed practice)
04/13/23 Dr. A. Hadwin 43
Timing of practice & reviewThis is called the Spacing Effect
• Distributing learning and practice over time (e.g. a little each day) leads to:
– Better long term recall– Less total time required to study
See the following for a really nice article about spacing studying:http://www.aft.org/pubs-reports/american_educator/summer2002/askcognitivescientist.html
04/13/23 Dr. A. Hadwin 44
Massed versus Distributed Practice
04/13/23 Dr. A. Hadwin 45
So if you are learning material from your readings and lecture
• Is it better to do massed learning session the day before your group meeting or distribute learning over time?
• DISTRIBUTED IS BETTER
04/13/23 Dr. A. Hadwin 46
BUT: Timing for rereading depends on when you need to remember
04/13/23 Dr. A. Hadwin 47
So if you are cramming for a meeting tomorrow?
• Is it better to do massed reread/review or distributed reread/review?
• MASSED MAY BE BETTER (but it is really short term and will mean you may forget most of it after the meeting
04/13/23 Dr. A. Hadwin 48
Reviewing
• Whether you remember something, depends upon how well you have stored it.
• SMART strategies facilitate reviewing
04/13/23 Dr. A. Hadwin 49
If you have organized information in memory, it will be easier to retrieve
04/13/23 Dr. A. Hadwin 50
World War II
American Revolution
Stuff for chp 1
History notes
Study guidenotes
How you have organized it in memory
• Will influence how you can retrieve it
• Will influence how your practice and review it
04/13/23 Dr. A. Hadwin 51
Retrieval is easier when…
• You know where to look in memory
• You can make use of retrieval cues
• Practice retrieving with the appropriate cues for this task– If you are going to need to remember things on the fly
in a meeting, you should practice retrieving them on the fly in conversations or practice meetings
04/13/23 Dr. A. Hadwin 52
Structure the information in the way you are going to need to
retrieve it
-if you need to see how concepts fit together, then don’t
study them as discrete things
Setting yourself up to retrieve• Create good internal organizations for material
• How it is retrieved at one time, affects how it is apt to be retrieved later on – PRACTICE retrieving and you are more likely to retrieve it
• Information that must be retrieved in a particular context or way, should be stored that way –practice retrieving under time constraints, etc.
• Try answering the problems under a time limit without being able to look anything up
• Try writing out your essay answers
04/13/23 Dr. A. Hadwin 53
• Develop external retrieval cues – mnemonics are examples,– tying a string around your finger is another)
• Question yourself about previously learned material
04/13/23 Dr. A. Hadwin 54
Things to think about• Why activate prior knowledge (what you already
know)?
• Why is learning hard work?
• How do you process information?S=M=A=R=T=
04/13/23 Dr. A. Hadwin 55
Thinking about work in this course
• ICE notes– SMART Operations
• Note forms– Structuring /organizing information to make
meaningful connections
• SLQ – using strategies for TU, GP, E,A– -using strategies for SMART.
