Memory
• Process by which we recollect prior experiences, information, skills learned in the past

Episodic
Special events, happening to or in the present of the person
Flash bulb– We photograph
many details everyday to recall events.

Generic memory
– general knowledge– Usually do not
remember when we acquired the information
– Most information learned in school

Procedural Memory
• Skills, procedures you have learned
• Once skills are learned unlikely to forget

Section 2 3 processes of memory
3Processes of
Memory
encode store Retrieve information
![Page 9: Chapter 7 Memory. Memory Process by which we recollect prior experiences, information, skills learned in the past](https://reader035.vdocuments.site/reader035/viewer/2022062301/56649f125503460f94c2638f/html5/thumbnails/9.jpg)
1st process-Encoding
• Information is changed (encoded) into a form that can be stored
• Visual codes– see them as a mental picture
• Acoustic codes– repeating out loud (auditory code) (_7_)
• Semantic codes (bone-dog)– (relating to meaning) words, sentences,
numbers
![Page 10: Chapter 7 Memory. Memory Process by which we recollect prior experiences, information, skills learned in the past](https://reader035.vdocuments.site/reader035/viewer/2022062301/56649f125503460f94c2638f/html5/thumbnails/10.jpg)
2nd process-Storage
• Maintenance rehearsal– repeating information over and over again to keep
from forgetting. (Phone numbers, addresses)
• Elaborative Rehearsal– put the word into sentences (used in education)
• Organizational– everything is put in files, files can be expanded,
• Filling errors– subject to errors, not a perfect system
![Page 11: Chapter 7 Memory. Memory Process by which we recollect prior experiences, information, skills learned in the past](https://reader035.vdocuments.site/reader035/viewer/2022062301/56649f125503460f94c2638f/html5/thumbnails/11.jpg)
3rd process Retrieval
• Locate stored information and returning it to conscious thought.
– Context-Dependent Memory
– State-Dependent Memory
![Page 12: Chapter 7 Memory. Memory Process by which we recollect prior experiences, information, skills learned in the past](https://reader035.vdocuments.site/reader035/viewer/2022062301/56649f125503460f94c2638f/html5/thumbnails/12.jpg)
Context-dependent memories
• Are dependent on the place– Park– church– School– Memories are encoded at the place
![Page 13: Chapter 7 Memory. Memory Process by which we recollect prior experiences, information, skills learned in the past](https://reader035.vdocuments.site/reader035/viewer/2022062301/56649f125503460f94c2638f/html5/thumbnails/13.jpg)
State-dependent memory
• Emotional state influences memories
• Moods and emotion that you were in or feeling help bring back memories
![Page 14: Chapter 7 Memory. Memory Process by which we recollect prior experiences, information, skills learned in the past](https://reader035.vdocuments.site/reader035/viewer/2022062301/56649f125503460f94c2638f/html5/thumbnails/14.jpg)
Section 3
3 stages of Memory
![Page 15: Chapter 7 Memory. Memory Process by which we recollect prior experiences, information, skills learned in the past](https://reader035.vdocuments.site/reader035/viewer/2022062301/56649f125503460f94c2638f/html5/thumbnails/15.jpg)
1st stage- Sensory Memory
• Immediate, initial recording of information that enter through our senses
![Page 16: Chapter 7 Memory. Memory Process by which we recollect prior experiences, information, skills learned in the past](https://reader035.vdocuments.site/reader035/viewer/2022062301/56649f125503460f94c2638f/html5/thumbnails/16.jpg)
Sensory Memory
Iconic memoryVisual stimuli called
Icon are held in sensoryMemory. Snapshots
Eidetic memoryAbility to remember visual Stimuli over long periods
Photographic memory
Echoic memoryMental races of sounds Called echoes are held
here. Are easier to remember.
![Page 17: Chapter 7 Memory. Memory Process by which we recollect prior experiences, information, skills learned in the past](https://reader035.vdocuments.site/reader035/viewer/2022062301/56649f125503460f94c2638f/html5/thumbnails/17.jpg)
2nd stage-Short-term Memory
Can disappear after 10-12 seconds unless transferred to long term memory.
Dialing a phone number helps you remember it
![Page 18: Chapter 7 Memory. Memory Process by which we recollect prior experiences, information, skills learned in the past](https://reader035.vdocuments.site/reader035/viewer/2022062301/56649f125503460f94c2638f/html5/thumbnails/18.jpg)
Primacy Effect
• Tendency to recall the
first items in a series of items
Recency Effect
• Tendency to recall the
last items in a series of items
![Page 19: Chapter 7 Memory. Memory Process by which we recollect prior experiences, information, skills learned in the past](https://reader035.vdocuments.site/reader035/viewer/2022062301/56649f125503460f94c2638f/html5/thumbnails/19.jpg)
Chunking Interference
• Organization of items into familiar or manageable units
• Can put in short-term memory 7 items
• Takes the places of information that is already in short-term memory
![Page 20: Chapter 7 Memory. Memory Process by which we recollect prior experiences, information, skills learned in the past](https://reader035.vdocuments.site/reader035/viewer/2022062301/56649f125503460f94c2638f/html5/thumbnails/20.jpg)
3rd stage-Long-term memory
• Must take certain steps to store it in long term memory
• No limit to how much can be stored
![Page 21: Chapter 7 Memory. Memory Process by which we recollect prior experiences, information, skills learned in the past](https://reader035.vdocuments.site/reader035/viewer/2022062301/56649f125503460f94c2638f/html5/thumbnails/21.jpg)
Reconstructive Schemas
• Memories are reconstructed from bits and pieces of our experiences.
• People will interpret information differently
• Mental representations that we form of the world by organizing information into knowledge
![Page 22: Chapter 7 Memory. Memory Process by which we recollect prior experiences, information, skills learned in the past](https://reader035.vdocuments.site/reader035/viewer/2022062301/56649f125503460f94c2638f/html5/thumbnails/22.jpg)
Section 4
Forgetting and Memory improvement
![Page 23: Chapter 7 Memory. Memory Process by which we recollect prior experiences, information, skills learned in the past](https://reader035.vdocuments.site/reader035/viewer/2022062301/56649f125503460f94c2638f/html5/thumbnails/23.jpg)
Forgetting and Memory Improvement
3 Basic Memory
Tasks
RecognitionIdentifying objects
or events that you have encountered
before
RecallBring it back to mind
reconstruct
RelearningCan relearn something
faster

Different kinds of forgetting
• Repression (Freud)
–Forget things on purpose
![Page 25: Chapter 7 Memory. Memory Process by which we recollect prior experiences, information, skills learned in the past](https://reader035.vdocuments.site/reader035/viewer/2022062301/56649f125503460f94c2638f/html5/thumbnails/25.jpg)
Amnesia
• Infantile
– Forgetting of earlier events
• Anterograde
– Memory loss caused by trauma
• Retrograde
– Period leading up to a traumatic event
![Page 26: Chapter 7 Memory. Memory Process by which we recollect prior experiences, information, skills learned in the past](https://reader035.vdocuments.site/reader035/viewer/2022062301/56649f125503460f94c2638f/html5/thumbnails/26.jpg)
Improving Memory
• Drill and practice
• Relate to things you already know
• For unusual association (lion- cats)
• Construct links
• Use mnemonic devices (Homes)
