The storage and retrieval of what has been learned or experienced
Involves 3 processes:
◦ Encoding
◦ Storage
◦ Retrieval

Transforming of information so the nervous system can process it
(Encoding is the process whose purpose is to assign a meaning to the information to be memorized. How effectively you can retrieve information depends on how deeply you have encoded it, and how well you have organized it in your memory.)
![Page 5: Module One: Booklet #8 - · PDF fileModule One: Booklet #8 ... conscious recollection Example: As we gain a skill, we gradually lose the ability to describe what we are doing](https://reader034.fdocuments.in/reader034/viewer/2022051508/5a9cb0017f8b9a451b8e6e76/html5/thumbnails/5.jpg)
Use your senses (hearing, sight, touch, taste, temperature, …) to encode and establish a memory
Uses 3 types of codes:
![Page 6: Module One: Booklet #8 - · PDF fileModule One: Booklet #8 ... conscious recollection Example: As we gain a skill, we gradually lose the ability to describe what we are doing](https://reader034.fdocuments.in/reader034/viewer/2022051508/5a9cb0017f8b9a451b8e6e76/html5/thumbnails/6.jpg)
Acoustic codes
◦ When you try to remember something by saying it aloud, or to yourself, repeatedly
Visual codes
◦ When you attempt to keep a mental picture
Semantic codes
◦ Try to make sense of things
![Page 7: Module One: Booklet #8 - · PDF fileModule One: Booklet #8 ... conscious recollection Example: As we gain a skill, we gradually lose the ability to describe what we are doing](https://reader034.fdocuments.in/reader034/viewer/2022051508/5a9cb0017f8b9a451b8e6e76/html5/thumbnails/7.jpg)
The process by which information is maintainedover a period of time
Information can be stored for a few seconds or for much longer
![Page 8: Module One: Booklet #8 - · PDF fileModule One: Booklet #8 ... conscious recollection Example: As we gain a skill, we gradually lose the ability to describe what we are doing](https://reader034.fdocuments.in/reader034/viewer/2022051508/5a9cb0017f8b9a451b8e6e76/html5/thumbnails/8.jpg)
Process of obtaining information that has been stored in memory
The ease in which information can be retrieved depends on how efficiently it was encoded and stored (as well as other factors such as genetic background)
![Page 9: Module One: Booklet #8 - · PDF fileModule One: Booklet #8 ... conscious recollection Example: As we gain a skill, we gradually lose the ability to describe what we are doing](https://reader034.fdocuments.in/reader034/viewer/2022051508/5a9cb0017f8b9a451b8e6e76/html5/thumbnails/9.jpg)
![Page 10: Module One: Booklet #8 - · PDF fileModule One: Booklet #8 ... conscious recollection Example: As we gain a skill, we gradually lose the ability to describe what we are doing](https://reader034.fdocuments.in/reader034/viewer/2022051508/5a9cb0017f8b9a451b8e6e76/html5/thumbnails/10.jpg)
![Page 11: Module One: Booklet #8 - · PDF fileModule One: Booklet #8 ... conscious recollection Example: As we gain a skill, we gradually lose the ability to describe what we are doing](https://reader034.fdocuments.in/reader034/viewer/2022051508/5a9cb0017f8b9a451b8e6e76/html5/thumbnails/11.jpg)
Very brief memory storage immediately following initial reception of a stimulus
Senses of sight and hearing (along with other senses) are able to hold an input for a fraction of a second before it disappears
![Page 12: Module One: Booklet #8 - · PDF fileModule One: Booklet #8 ... conscious recollection Example: As we gain a skill, we gradually lose the ability to describe what we are doing](https://reader034.fdocuments.in/reader034/viewer/2022051508/5a9cb0017f8b9a451b8e6e76/html5/thumbnails/12.jpg)
Are two types of sensory memory:
◦ Iconic memory
Visual sensory memory
◦ Echoic memory
Type of sensory memory that holds auditory information for 1 to 2 seconds)
![Page 13: Module One: Booklet #8 - · PDF fileModule One: Booklet #8 ... conscious recollection Example: As we gain a skill, we gradually lose the ability to describe what we are doing](https://reader034.fdocuments.in/reader034/viewer/2022051508/5a9cb0017f8b9a451b8e6e76/html5/thumbnails/13.jpg)
Sensory memory serves three functions:
◦ Prevents you from being overwhelmed by all the various incoming stimuli
Anything you don’t pay attention to vanishes in seconds!
◦ Gives you decision time
The information is there just long enough for you to decide whether this information is worth paying attention to (if it is then it goes to short-term memory)
![Page 14: Module One: Booklet #8 - · PDF fileModule One: Booklet #8 ... conscious recollection Example: As we gain a skill, we gradually lose the ability to describe what we are doing](https://reader034.fdocuments.in/reader034/viewer/2022051508/5a9cb0017f8b9a451b8e6e76/html5/thumbnails/14.jpg)
◦ Allows for continuity and stability
Makes images smooth and continuous and play back auditory information so can recognize sounds as words
![Page 15: Module One: Booklet #8 - · PDF fileModule One: Booklet #8 ... conscious recollection Example: As we gain a skill, we gradually lose the ability to describe what we are doing](https://reader034.fdocuments.in/reader034/viewer/2022051508/5a9cb0017f8b9a451b8e6e76/html5/thumbnails/15.jpg)
Memory that is limited in capacity (i.e. amount) to about seven items and in duration by the subject’s active rehearsal
Consists of the things you have in your conscious mind at any one moment
Does not necessarily involve paying close attention
Contains information that is of possible interest
![Page 16: Module One: Booklet #8 - · PDF fileModule One: Booklet #8 ... conscious recollection Example: As we gain a skill, we gradually lose the ability to describe what we are doing](https://reader034.fdocuments.in/reader034/viewer/2022051508/5a9cb0017f8b9a451b8e6e76/html5/thumbnails/16.jpg)
![Page 17: Module One: Booklet #8 - · PDF fileModule One: Booklet #8 ... conscious recollection Example: As we gain a skill, we gradually lose the ability to describe what we are doing](https://reader034.fdocuments.in/reader034/viewer/2022051508/5a9cb0017f8b9a451b8e6e76/html5/thumbnails/17.jpg)
Maintenance Rehearsal
◦ System for remembering involving repeating information to oneself without attempting to find meaning in it
◦ Short-term memory lasts a bit less than 20 seconds without rehearsal
Ex. Saying phone number aloud!!!
![Page 18: Module One: Booklet #8 - · PDF fileModule One: Booklet #8 ... conscious recollection Example: As we gain a skill, we gradually lose the ability to describe what we are doing](https://reader034.fdocuments.in/reader034/viewer/2022051508/5a9cb0017f8b9a451b8e6e76/html5/thumbnails/18.jpg)
Chunking
◦ The process of grouping items to make them easier to remember
◦ Short-term memory can only hold about seven unrelated items
◦ One of the tricks of memorizing a lot of information quickly is to chunk together the items as fast as they come in, if we connect items in groups, we have fewer to remember
![Page 19: Module One: Booklet #8 - · PDF fileModule One: Booklet #8 ... conscious recollection Example: As we gain a skill, we gradually lose the ability to describe what we are doing](https://reader034.fdocuments.in/reader034/viewer/2022051508/5a9cb0017f8b9a451b8e6e76/html5/thumbnails/19.jpg)
Primacy-Recency Effect
◦ You are better able to recall information presented at the beginning and end
(the first stuff you have had time to rehearse, the last stuff is still recent, and the middle is lost because you were trying to rehearse the first ones and remember the new ones!)
![Page 20: Module One: Booklet #8 - · PDF fileModule One: Booklet #8 ... conscious recollection Example: As we gain a skill, we gradually lose the ability to describe what we are doing](https://reader034.fdocuments.in/reader034/viewer/2022051508/5a9cb0017f8b9a451b8e6e76/html5/thumbnails/20.jpg)
Working Memory
◦ System for processing and working with current information
◦ Includes both short-term memory (events that just occurred) and information stored in long-term memory now recalled for current information
![Page 21: Module One: Booklet #8 - · PDF fileModule One: Booklet #8 ... conscious recollection Example: As we gain a skill, we gradually lose the ability to describe what we are doing](https://reader034.fdocuments.in/reader034/viewer/2022051508/5a9cb0017f8b9a451b8e6e76/html5/thumbnails/21.jpg)
![Page 22: Module One: Booklet #8 - · PDF fileModule One: Booklet #8 ... conscious recollection Example: As we gain a skill, we gradually lose the ability to describe what we are doing](https://reader034.fdocuments.in/reader034/viewer/2022051508/5a9cb0017f8b9a451b8e6e76/html5/thumbnails/22.jpg)
It is storage of information over extended periods of time
Stored according to categories or features (often likened to filing cabinet)
Capacity seems to be limitless
Contains representations of countless facts, experiences and sensations
![Page 23: Module One: Booklet #8 - · PDF fileModule One: Booklet #8 ... conscious recollection Example: As we gain a skill, we gradually lose the ability to describe what we are doing](https://reader034.fdocuments.in/reader034/viewer/2022051508/5a9cb0017f8b9a451b8e6e76/html5/thumbnails/23.jpg)
Involves all of the previously described processes (pass through sensory memory, to short-term memory and then into long-term memory)
Although things may become less accessible, elements will still be stored in long-term memory
There are four types of long-term memory….
![Page 24: Module One: Booklet #8 - · PDF fileModule One: Booklet #8 ... conscious recollection Example: As we gain a skill, we gradually lose the ability to describe what we are doing](https://reader034.fdocuments.in/reader034/viewer/2022051508/5a9cb0017f8b9a451b8e6e76/html5/thumbnails/24.jpg)
a) Semantic Memory
Knowledge of language, including its rules, words, and meanings
We share this knowledge with other speakers of our language
![Page 25: Module One: Booklet #8 - · PDF fileModule One: Booklet #8 ... conscious recollection Example: As we gain a skill, we gradually lose the ability to describe what we are doing](https://reader034.fdocuments.in/reader034/viewer/2022051508/5a9cb0017f8b9a451b8e6e76/html5/thumbnails/25.jpg)
b)Episodic Memory
Memory of one’s life, including time of occurrence
Stored here are things where time of occurrence is important
Example: When you woke up this morning
![Page 26: Module One: Booklet #8 - · PDF fileModule One: Booklet #8 ... conscious recollection Example: As we gain a skill, we gradually lose the ability to describe what we are doing](https://reader034.fdocuments.in/reader034/viewer/2022051508/5a9cb0017f8b9a451b8e6e76/html5/thumbnails/26.jpg)
c) Declarative Memory
Memory of knowledge that can be called forth consciously as needed
Involves both episodic and semantic memory
Information you call forth consciously and use as you need it
![Page 27: Module One: Booklet #8 - · PDF fileModule One: Booklet #8 ... conscious recollection Example: As we gain a skill, we gradually lose the ability to describe what we are doing](https://reader034.fdocuments.in/reader034/viewer/2022051508/5a9cb0017f8b9a451b8e6e76/html5/thumbnails/27.jpg)
d) Procedural Memory
Memory of learned skills that does not require conscious recollection
Example: As we gain a skill, we gradually lose the ability to describe what we are doing
![Page 28: Module One: Booklet #8 - · PDF fileModule One: Booklet #8 ... conscious recollection Example: As we gain a skill, we gradually lose the ability to describe what we are doing](https://reader034.fdocuments.in/reader034/viewer/2022051508/5a9cb0017f8b9a451b8e6e76/html5/thumbnails/28.jpg)
![Page 29: Module One: Booklet #8 - · PDF fileModule One: Booklet #8 ... conscious recollection Example: As we gain a skill, we gradually lose the ability to describe what we are doing](https://reader034.fdocuments.in/reader034/viewer/2022051508/5a9cb0017f8b9a451b8e6e76/html5/thumbnails/29.jpg)
![Page 30: Module One: Booklet #8 - · PDF fileModule One: Booklet #8 ... conscious recollection Example: As we gain a skill, we gradually lose the ability to describe what we are doing](https://reader034.fdocuments.in/reader034/viewer/2022051508/5a9cb0017f8b9a451b8e6e76/html5/thumbnails/30.jpg)
Techniques for improving memory are based on efficient organization of the things you learn and on chunking information into easily handled packages
![Page 31: Module One: Booklet #8 - · PDF fileModule One: Booklet #8 ... conscious recollection Example: As we gain a skill, we gradually lose the ability to describe what we are doing](https://reader034.fdocuments.in/reader034/viewer/2022051508/5a9cb0017f8b9a451b8e6e76/html5/thumbnails/31.jpg)
One way to remember is through elaborative rehearsal
◦ Linking of new information to material that is already known
◦ Relate new information to what you already know
◦ The more meaningful something is, the easier it will be to remember
![Page 32: Module One: Booklet #8 - · PDF fileModule One: Booklet #8 ... conscious recollection Example: As we gain a skill, we gradually lose the ability to describe what we are doing](https://reader034.fdocuments.in/reader034/viewer/2022051508/5a9cb0017f8b9a451b8e6e76/html5/thumbnails/32.jpg)
You remember things more vividly you associate then with things already stored in memory or with a strong emotional experience
The more categories a memory is “indexed” under, the more accessible it is and each association can serve as a trigger for the memory
The more senses and experiences you use when trying to memorize something, the more likely it is that you will be able to retrieve it
![Page 33: Module One: Booklet #8 - · PDF fileModule One: Booklet #8 ... conscious recollection Example: As we gain a skill, we gradually lose the ability to describe what we are doing](https://reader034.fdocuments.in/reader034/viewer/2022051508/5a9cb0017f8b9a451b8e6e76/html5/thumbnails/33.jpg)
Good ways to protect a memory from interference:
◦ Overlearn it (to keep on rehearing it even after you think you know it well)
◦ Avoid studying similar material together
◦ Space out your learning
![Page 34: Module One: Booklet #8 - · PDF fileModule One: Booklet #8 ... conscious recollection Example: As we gain a skill, we gradually lose the ability to describe what we are doing](https://reader034.fdocuments.in/reader034/viewer/2022051508/5a9cb0017f8b9a451b8e6e76/html5/thumbnails/34.jpg)
Techniques for using associations to memorize and retrieve information such as:
◦ Methods of Loci
◦ Rhymes
◦ Mental Pictures
◦ Giving a word for each letter
