THREE PROCESSES OF MEMORY Encoding Storage Retrieval

Encoding The translating of information into a form that can be stored in your brain. Example: Sound of my voice is converted into a format your brain can store and later retrieve psychologically. Like typing words and then saving your work on a computer.

Types of Encoding: Semantic Encoding Encoding the meaning of something Encoding information that is meaningful makes recall easier This is the best type of encoding

Semantic Encoding Example Is it easier to remember this list of letters? OTTFFSSENT What if we told you that each letter is the first letter of the series of numbers from One through Ten? One, Two, Three, Four, Five, Six, Seven, Eight, Nine, Ten

Self-Reference Effect Making information meaningful to a person by making it relevant to one’s life Ask yourself: “How does this relate to me?”

Acoustic Encoding Encoding information based on the sounds of the information Example: Repeat what you want to remember over and over.

Visual Encoding Encoding information based on images Memorizing information by picturing it in your mind. Least effective form of encoding.

Visual Encoding (From Craik & Tulving, 1975)

Encoding: Mnemonic Devices

Mnemonic Device A memory trick or technique for remembering specific facts “Every good boy does fine” to remember the notes on the lines of the scale “People say you could have odd lots of good years” as a way to remember how to spell “psychology”

Method of Loci A mnemonic device in which the person associates items to be remembered with imaginary places Place items you want to remember in your house.

Peg-Word System A mnemonic device in which the person associates items to remember with a list of peg words already memorized Goal is to visualize the items to remember with the items on the pegs

Peg Word System

Categorical Clustering Grouping items you want to remember by categories Example: Grocery list organized by aisles or food category.

Acronyms Set of letters from a word or phrase in which each letter stands of a certain other word or concept. Example: HOMES = Names of the Great Lakes

Acrostics Initial letters that taken in order form a word or phrase that trigger what you want to remember. Example: Please Excuse My Dear Aunt Sally (Math) Example: Every Good Boy Deserves Fudge (Music)

Interactive Images Link a set of isolated words by creating visual representations for the words and then picturing interactions among the items. Example: If you had to remember a list of random things like an aardvark, pencil, table and book picture the aardvark sitting on a table holding pencil in its claws and writing in a book.

Keyword System Learning isolated words by linking sounds and meanings together. Example: Elvis shook his pelvis Stalactite holds tight to the ceiling Fibula lies beneath the Tibula Tibula is on top of the fibula

Once things are encoded they move to STORAGE 2ND Process of Memory where encoded information is maintained over time. Like a computer’s hard drive but it never gets full.

How can you get information into storage for later use? Maintenance Rehearsal – Repeating information over and over More time spent rehearsing, the longer the info will be remembered. Information learned in this way doesn’t last over the long term. Elaborative Rehearsal – Relating information to something you already know. Information learned in this way will last longer in your memory

Storage is like a file cabinet As you learn more info your brain categorizes it into many different groups and classes based on common features. This can lead to filing errors when we file information incorrectly.

Retrieval

Retrieval The process of getting information out of memory storage and into conscious thought. Two forms of retrieval Recall Recognition

Recall A measure of memory in which the person must retrieve information learned earlier Example: Essay, fill-in-the-blank, and short answer test questions test recall

Recognition A measure of memory in which a person must identify items learned earlier Example: Multiple choice and matching questions test recognition; the correct answer is in front of you – you just need to recognize it.

Retrieval: Context

Context Effect The enhanced ability to retrieve information when you are in an environment similar to the one in which you encoded the information Example: Take a walk in your elementary school and memories from that time will come flooding back.

Context

Retrieval: State Dependency

State Dependent Memory The enhanced ability to retrieve information when the person is in the same physical and emotional state they were in when they encoded the information Example: When you’re angry you remember other times you were angry.

Tip of the Tongue Phenomenon When you are sure you know something but just cannot verbalize it. This is frustrating!

The Three Processes of Memory Let’s Review The Three Processes of Memory

Encoding The processing of information into the memory system. Typing info into a computer Getting a girls name at a party

Storage The retention of encoded material over time. Trying to remember her name when you leave the party. Pressing Ctrl S and saving the info.

Retrieval The process of getting the information out of memory storage. Seeing her the next day and calling her the wrong name (retrieval failure). Finding your document and opening it up.
