“THREE is the KEY for MEMORY” Qz. #6 pages 181-201 Chapter 5
What do you remember? Your birth date Your phone number Your health card number Your address and postal code Your license plate number Your student number Your social insurance number What you ate for dinner last night What do you remember?
On the other hand, imagine what it would be like if you never forgot anything You would have difficulties focussing on any one thing In order to function properly in life, we need to be able to selectively remember certain things, while at the same time forget others Most of us only think of our memory when we can’t remember something; any other time our memory comes naturally we take it for granted
Learning = a process that will modify a subsequent behaviour; it is a permanent change in our knowledge or in our behaviour as a result of an experience Memory = the ability to remember past experiences; Memory is basically nothing more than the record that is left behind by a learning process/experience Memory versus Learning Many people often confuse memory with learning Learning = a process that will modify a subsequent behaviour; it is a permanent change in our knowledge or in our behaviour as a result of an experience Memory = the ability to remember past experiences Memory is essential to all learning because it allows you to store and retrieve the information that you learn Memory is basically nothing more than the record that is left behind by a learning process/experience Memory vs. Learning
…is defined as the capacity to acquire, retain, and recall knowledge and skills. Memory Defined as the capacity to acquire, retain, and recall knowledge and skills The ability to recall specific knowledge, which is what most people consider memory to be, is just one type of memory Remembering how to speak a language, remembering your first day of school, remembering where your locker is located – these all require a different type of memory What is Memory?
Your brain works on electrochemical energy weights approximately 3 pounds Size of fists together More than 100 billion brain cells called neurons Connections more important than number
Types of Memory Episodic Memory Semantic Memory Procedural Memory Ability to recall events from a specific past experience i.e. what was on the last Anthropology test Semantic Memory Knowledge of how the world works, but you haven’t actually experienced it yourself i.e. what is an Australopithecus afarensis? Procedural Memory Knowledge of how to do things i.e. how to ride a bike The Different Types of Memory Episodic Memory Recalling events from a specific past experience i.e. what was on the last Anthropology test Semantic Memory Knowledge of how the world works, but you haven’t actually experienced it yourself i.e. what is an Australopithecus afarensis? Procedural Memory Knowledge of how to do things i.e. how to ride a bike Types of Memory
Three Types of Memory 1.Episodic – memories of personal experience 2.Semantic – general knowledge or memory for facts 3.Procedural – memory for skills Episodic – Do you remember your first interaction with a personal computer? Semantic – Do you know the meaning of personal computer? Procedural – Are you fluent in the use of a personal computer?
Three Levels of Memory
Levels of Memory Sensory Memory Receives information from the environment through your five senses Records this information for only a few seconds Enables you to hold information long enough to record what is necessary i.e. what does it feel like to bang your elbow on the desk? Different Levels of Memory Sensory Memory Receives information from the environment through your five senses Records this information for only a few seconds Enables you to hold information long enough to record what is necessary Allows you to select and focus on what you think should be retained from all the sensory information you are receiving i.e. what does it feel like to bang your elbow on the desk? i.e. the chair on your back, the sound of a noise in the hall, the taste of gum in your mouth, the sight of a squirrel in a tree, the announcement of a pop quiz tomorrow Levels of Memory
That analogy makes a lot of "cents"! Three Levels of Memory 1. Sensory Memory - the type or stage of memory first encountered by a stimulus. Sensory memory holds impressions briefly, but long enough so that series of perceptions are psychologically continuous. Saccadic Eye Movement Memory trace Sensory Register Iconic memory Echoic memory That analogy makes a lot of "cents"!
Different Levels of Memory Short-Term Memory (aka. Working Memory) Memory that is stored for 15 – 20 seconds information in your mind right now (unrehearsed memory) If you continue to work with the information, it will remain in your STM longer or will be transferred into your LTM can store up to 7, separate, unorganized items, plus or minus 2 more than 7 items begins to stress out our STM unless we organize the info into meaningful groups i.e. NFL, NHL, NBA are easier to remember than FNL, HLN, ABN Information in your STM is lost by decay (the fading of information over time) or displacement (replaced by new information) Short-Term Memory (aka. working memory) This refers to information in your sensory memory or information you have retrieved from your long-term memory Memory that is stored for 15 – 20 seconds; it is the information that is going on in your mind right now (unrehearsed memory) If you continue to work with the information, it will remain in your short term memory for longer (this is called maintenance rehersal) If not, it will either be discarded or it will be transferred into your long-term memory i.e. phone numbers can store up to 7, separate, unorganized items; plus or minus 2 (i.e. a 7-digit phone number) more then 7 items begins to stress out our short term memory UNLESS we organize the information into meaningful groups/chunks i.e. area code, three digit exchange, last for digits i.e. NFL, NHL, NBA are easier to remember than FNL, HLN, ABN Information in your short term memory is lost by decay (the mere fading of information over time) or displacement (it is replaced by new memory) Different Levels of Memory
Short Term Memory (STM) [ 7+/-2 - about 1 min.] SERIAL POSITION EFFECT – the tendency to recall more accurately the first and last items in a series. PRIMACY EFFECT – the tendency to recall the initial items in a series of items. RECENCY EFFECT – the tendency to recall the last items in a series of items.

Testing your short-term memory
Different Levels of Memory Long-Term Memory Information that is important and meaningful to you will be stored in your long-term memory Memory that is longer than 15 – 20 seconds (can last minutes or a lifetime) This memory has been compared to the workings of a library Information is encoded and stored in a systematic and organized way It is retrieved by giving cues (like an online search) It is lost when it is misplaced, improperly stored, or erased Long-Term Memory Information that is important and meaningful to you will be stored in your long-term memory This memory has been compared to the workings of a library Information is encoded and stored in a systematic and organized way It is retrieved by giving cues (like an online search) It is lost when it is misplaced, improperly stored, or erased Memory that is longer than 15 – 20 seconds (can last minutes or a lifetime) The limits of memory are still unknown; as of yet, humans have never reached their memory capacity like computers do Different Levels of Memory
Mnemonic Device EXAMPLES System for remembering in which items are related to easily recalled sets of symbols, such as acronyms, phrases, or jingles EXAMPLES “i” before “e” except after “c” “Be, all that you can be!” “Every Good Boy Does Fine!” “Like a Rock”
Episodic - Semantic - Procedural Which is involved? 1.First Kiss 10.Use a computer 2.Riding a bike 11.Spell C-A-T 3.Walking through a maze 12.Driving a car 4.List the 50 states 13.H20 5.Define Memory 14.Describe a fight to someone 6.Cut and Paste an art project 15.First day in high school 7.Writing notes off an overhead 8.Formula for classical conditioning 9.Witness a car accident
Three Processes of Memory 1.ENCODING - modifying information so that it can be placed in memory a. visual code b. acoustic code c. semantic code 2.STORING - maintenance of information over time a. maintenance rehearsal 3.RETRIEVING - location of stored information and its return to consciousness a. proper cues
You have to go up... RETRIEVING STORING ENCODING before you come down!
Short Term Memory (STM) OTHER KEY TERMS: Chunk - a stimulus or group of stimuli that are perceived as a discrete piece of information *Rote - mechanical associative learning that is based on repetition Displace - in memory theory, to cause chunks of information to be lost from short term memory by adding new items
In order to study FORGETTING 1st We need to know what nonsense syllables are. Remember, 3 is the key 2nd We need to know what the three basic memory tasks are. 3rd How are nonsense syllables and the three memory tasks related?
2nd We need to know what the three basic memory tasks are. Three Tasks of Memory A. Recognition – the easiest memory task, involving identification of objects or events encountered before B. Recall – retrieval and reconstruction of learned material a. paired associates – nonsense syllables presented in pairs in experiments that measure recall C. Relearning – a measure of retention; material is usually relearned more quickly than it is learned initially a. method of savings & savings
INTERFERENCE THEORY We may forget stored material because other learning interferes with it Retroactive Interference - forget the old because of the new Provide a few examples Proactive Interference - forget the new because of the old Provide a few examples
Amnesia Childhood Amnesia What is your earliest memory? How old were you? State reasons for childhood amnesia Check textbook (pages 206-207) Anterograde Amnesia Failure to remember events that occur AFTER physical trauma because of the effects of the trauma Retrograde Amnesia Failure to remember events that occur prior (retro = old) to physical trauma because of the effects of the trauma
Improving Memory 1. Visualize it! Visualize it! 2. Chain it! Chaining 3.Place it! The Method of Loci 4.Chunk it! Chunking 5.Acrostic it! Those Catchy Phrases
Ten Principles of Memory Pay attention Get the info right the 1st time Be sure you fully understand Try to see the significance of what you’re learning Involve your ego, if possible Associate new material with related facts you know Organize the material so that it can be stored If there is a basis for doing so, divide and group Reinforce what you’ve learned through repetition Recite often !
