Memory Psychology 40S C. McMurray

Memory Memory is the basis for knowing your friends, your neighbors, the English language, the national anthem, and yourself. If memory was nonexistent, everyone would be a stranger to you; every language foreign; every task new; and even you yourself would be a stranger.

The Phenomenon of Memory Memory is any indication that learning has persisted over time. It is our ability to store and retrieve information.

My Memory: Finish the following statements in your notebook: My memory is __________ (Excellent, Good, Fair, or Poor) This is because _______ I am usually good at remembering _____ This is because ______ I would like to get better at remembering _____

Memory: 3 Levels of Processing Preview Question 1: How do psychologists describe the human memory system? Keyboard (Encoding) Disk (Storage) Monitor (Retrieval) Sequential Process

Information Processing Model Encoding – get information into our brain Storage – retain that information Retrieval – get the information back out (This information processing model was developed by Atkinson and Richard Shiffrin) Other psychologists have added to this process by suggesting that the first step is a split-second encoding of sensory memory (all the sensory information in the memory system)

3 Storage Systems Sensory Stimulus Sensory Memory Short Term Memory Long Term Memory Sensory Stimulus

How We Encode Reflect on what has happened so far in your day. What time did you wake up What did you have for breakfast What time did you get to school What was your route to get to psychology class today? Who have you spoken to today Clearly, automatic processing happens so effortlessly that it is difficult to turn off. We automatically process information about space, time, and frequency. At any point did you think, “I have to remember these events because Mrs. McMurray might ask me!”

Encoding: Getting Information In How We Encode Some information (route to your school) is automatically processed. (Automatic Processing) However, new or unusual information (friend’s new cell-phone number) requires attention and effort. (Effortful Processing)

Effortful Processing Committing new information to memory requires effort just like learning a concept from a textbook. Such processing leads to durable and accessible memories. Spencer Grant/ Photo Edit © Bananastock/ Alamy

What We Encode Encoding by meaning We need to make what we want to remember meaningful (Semantic Encoding) 2. Encoding by images We can also remember things that allow us to form a visual image Encoding by organization We also remember information when it is organized

Encoding Meaning Semantic Encoding Self-reference Effect – Relating the information to your own life making it personally relevant. A lot of the material in this course is easy to learn and remember because it is all about behavior and mental processes as they relate to you

Visual Encoding Mental pictures (imagery) are a powerful aid to effortful processing, especially when combined with semantic encoding. Both photos: Ho/AP Photo Showing adverse effects of tanning and smoking in a picture may be more powerful than simply talking about it.

Organizing Information for Encoding Break down complex information into broad concepts and further subdivide them into categories and subcategories. Chunking Hierarchies Concept Maps

Mnemonics Visual and Organizational Encoding Imagery is at the heart of many memory aids. Mnemonic techniques use vivid imagery and organizational devices in aiding memory. Three common mnemonic devices are: Acronyms Method of loci or Memory Palace Peg-word system

Remembering Names House Bunny remembering names The Office... Mnemonic Device to remember names House Bunny remembering names

Knuckle mnemonic for the number of days in each month Knuckle mnemonic for the number of days in each month. Each projecting knuckle represents a 31-day month.

Mnemonic Devices: Peg Word Peg Word is a technique for memorizing lists. Learn this rhyme and link it to the list of things you need to remember. The objects “bun” are the pegs of the system. One is a bun Two is a shoe Three is a tree Four is a door Five is a hive Six is sticks Seven is heaven Eight is a gate Nine is wine Ten is a hen

Acronyms are another way of chunking information to remember it. HOMES = Huron, Ontario, Michigan, Erie, Superior ROY G. BIV = Red, Orange, Yellow, Green, Blue, Indigo, Violet

Hierarchy Complex information broken down into broad concepts and further subdivided into categories and subcategories.

Concept Maps A concept mapping is a technique that organizes information. Concept maps show the relationship between concepts. They allow you to visualize connections and organize lots of information into a form that is easily understood. It is easier for the brain to make meaning, when information is organized into visual formats.

Review: Encoding Encoding is translating sensory information into a form in which it can be stored. Encoding is the first process of memory.

Storage Short Term Memory/Working Memory After information is encoded, it must be stored. Storage is the second process of memory; it is the maintenance of encoded information over time. The strategies we use for storage are closely related to the strategies we use for encoding.

Short-Term Memory (Working Memory) Our short-term memory is limited in capacity to about seven (unrelated) items and lasts approximately 20 seconds without rehearsal. Activity: Magical Number 7 plus or minus 2 Short term memory contains information that is “of possible interest.” Information worth holding on to must be rehearsed to transfer it to long-term memory.

Rehearsal To keep information in short-term memory for more than a few seconds, you usually have to repeat the information to yourself, in your mind or out loud. To demonstrate the impact of rehearsal, write down the gifts in the familiar song “Twelve Days of Christmas”

Retrieval (Long Term Memory) Retrieval is the third process of memory; it is the process of locating stored information and returning it to conscious thought. Getting the information OUT! Keyboard (Encoding) Disk (Storage) Monitor (Retrieval)

Long-Term Memory Long term memory refers to the storage of information over extended periods of time. Essentially unlimited capacity store.

Hippocampus Hippocampus (Latin for seahorse) is associated primarily with memory.

Stress Hormones & Memory Heightened emotions (stress-related or otherwise) make for stronger memories. Flashbulb memories are clear memories of emotionally significant moments or events Scott Barbour/ Getty Images

Measures of Memory In recall, the person must retrieve information using effort. (A fill-in-the blank test requires recall.) Mrs. McMurray’s youngest daughter is ______.

Measures of Memory In recognition, the person must identify an item amongst other choices. (A multiple-choice test requires recognition.) Name Mrs. McMurray’s youngest daughter. Sally Sue Laura Lorraine Jimmy John

Context Effects Putting yourself back in the context where you experienced something can prime your memory retrieval. Scuba divers recall more words underwater if they learned the list underwater, while they recall more words on land if they learned that list on land Preview Question 8: How do external contexts and internal emotions influence memory retrieval?

Moods and Memories We usually recall experiences that are consistent with our current mood (state-dependent memory). Emotions, or moods, serve as retrieval cues. Our memories are mood-congruent. Mood-congruent memory – the tendency to recall experiences that are consistent with one’s current good or bad mood. Jorgen Schytte/ Still Pictures

VSauce explains Deja Vu Déjà Vu Déjà Vu means “I've experienced this before.” Cues from the current situation may unconsciously trigger retrieval of an earlier similar experience. VSauce explains Deja Vu © The New Yorker Collection, 1990. Leo Cullum from cartoonbank.com. All Rights Reserved

Retrieval Cues Memories may be inaccessible until we have cues for retrieving them. Memory is held in storage by a web of associations. To retrieve a specific memory, you first need to identify one of the strands that leads to it…this process is called PRIMING

Forgetting An inability to retrieve information due to poor encoding, storage, or retrieval. Preview Question 9: Why do we forget?

What do you remember?

Answer the following: How many people are in the picture? How many females were there? How many fans were NOT wearing Jets gear? What was the fan in the middle of the front row doing? What colour was women’s hair in the top row on the left? How many fans were wearing glasses? Which fan was smiling the most? Which fan had red hair? What was Stephen Harper doing? Which fan had a moustache? Draw what the moustache looked like.

We cannot remember what we do not encode. Encoding Failure We cannot remember what we do not encode.

False Memories Activity… How False Memories are Made

Memory Construction While tapping our memories, we filter or fill in missing pieces of information to make our recall more coherent. Misinformation Effect: Incorporating misleading information into one's memory of an event. Preview Question 10: How do misinformation, imagination, and source amnesia influence our memory construction? How real-seeming are false memories?

Misinformation and Imagination Effects Eyewitnesses reconstruct their memories when questioned about the event. Depiction of the actual accident.

Misinformation Group A: How fast were the cars going when they hit each other? Group B: How fast were the cars going when they smashed into each other?

Memory Construction A week later they were asked: Was there any broken glass? Group B (smashed into) reported more broken glass than Group A (hit).

Constructed Memories Loftus’ research shows that if false memories (lost at the mall or drowned in a lake) are implanted in individuals, they construct (fabricate) their memories. Don Shrubshell

Improving Memory Study repeatedly to boost long-term recall. Spend more time rehearsing or actively thinking about the material. Make material personally meaningful. Use mnemonic devices: associate with peg words — something already stored make up a story chunk — acronyms Preview Question 12: How can an understanding of memory contribute to more effective study techniques?

Improving Memory Activate retrieval cues — mentally recreate the situation and mood. Recall events while they are fresh — before you encounter misinformation. Minimize interference: Test your own knowledge. Rehearse and then determine what you do not yet know. © LWA-Dann Tardiff/ Corbis
