Chapter 9-Memory Day 1 Memory Memory: persistence of learning over time via the _______________________ Gives us our sense of self and connects us to _______________________. Vivid Memories Flashbulb Memories: ___________________________________________ Usually personally meaningful or historically significant. Memory as Information Processing Memory is similar to a computer (write to file, save to disk, read from disk). 3 Basic Steps to Memory: 1.Encoding: ______________________________________. •File Cabinet •Needs to be organized 2.Storage: ____________________________________________________ 3.Retrieval: __________________________________________________. Three Stage Processing Model of Memory Stage One: The ____________________________________ in the memory system is referred to as __________________________. Stage Two: sensory memories are processed into _________________ your activated memory which can only _____________________________________. Stage Three: short term memories are encoded into _________________, the __________________________ and limitless storehouse from which we retrieve. Concept of Working Memory Working Memory: similar to short-term memory but ___________________________ ________________________________________ Working Memory and Short-Term Memory are both quite _______________________ ______________________________________ You can only hold so much information in your working memory at one given time. Magic Number tends to be ____________________ Types of Encoding Automatic Processing _________________________________________ space time frequency ________________________________ information word meanings we ___________________________________________ Effortful Processing: type of encoding that __________________________________ Ex: Learning new vocabulary terms, memorizing historical events/chronology, etc. Encoding can be aided by maintenance rehearsal: ________________________ of information in consciousness or even more successfully by elaborate rehearsal: processing of _____________________________ which can more easily help produce long term memories. King of Memory Experiments is Hermann Ebbinghaus Wanted to research capacity of verbal memory. Looked to study to see capacity of peoples’ memories to study ___________________ ________________________________ Ex: JIH, FUB, YOX, XIR General Findings 1. Next in Line Effect- don’t concentrate/remember when you know you are going to __________________________________ 2. Info ________________________________ is not remembered 3. ______________________________ is not remembered 4. _________________________________. The more rehearsal he did on day 1, the less rehearsal it took to learn the syllables again on day 2. Over learning increased retention. 5. The Spacing Effect: the tendency for studying over a long period of time produces ________________________________ than is achieved through massed study or practice. SPACED STUDYING BEATS CRAMMING!!! 6. Serial Position Effect: our tendency to recall best _________________________. Ex: Presidents Types of Encoding Semantic Encoding: encoding of meaning, _______________________ of words… yields best memory. Acoustic Encoding: _________________________, especially the sound of words…. usually the _____________________________. “ if the glove doesn’t fit , you must acquit” Visual Encoding: the ____________________________________________. Self Reference Effect- do better on things we _______________________________ Encoding Imagery Imagery: ____________________________, helps effortful processing especially when combined with semantic encoding. Recall of events is often colored by __________________________________…usually remember events differently than you evaluated them at the time. Mneumonics: ______________________, often use vivid imagery and organizational devices. Organizing Information for Encoding Chunking organizing items into __________________________________ like horizontal organization- 1776149218121941 1776 1492 1812 1941 __________________________________ often occurs automatically use of acronyms HOMES- Huron, Ontario, Michigan, Erie, Superior A way to get over the __________________________ rule Hierarchies ________________________________. is remembered better complex information broken down into broad concepts and further subdivided into _________________________________________________ Day 2- Sensory, Short and long term memory Storage: Sensory Memory Sensory Memory: refers to the initial recording of sensory information in the memory system. All information is held here briefly (_______________________________) Filter system- ___________________________________________________ Sensory Memories include both: 1.Iconic Memory: a momentary sensory memory of a ____________________. Memory only lasts for a few tenths of a second. 2.Echoic Memory: a momentary sensory memory for ________________________. Sound memories can usually last up to _____________________________. Sensory memory is ______________________________ since it fades as we try to measure it. How Does Sensory Memory Get Processed Into Memory? Sensory memories disappear unless you focus your _________________________ on the information. _________________________________________________________________ Rehearse things and ____________________________________________ to yourself ____________________ to get info into short term and then eventually into long term memory storage Storage: Short Term Memory STM- has a _________________________ and duration Couple seconds ____________________________ R e m e m b e r ______ ____ ______ _______ _____ _____ _______ _______ Remember things we hear better than things we see If you use chuncking, rehearsal and self reference you will remember things longer Only through ________________________________ do short-term memories become long term memories. Storage- Long Term Memory Average adult has a _______________________________ in their memory If you don’t properly encode info, it __________________________________ We don’t always encode info correctly LTM= _________________________________ Rajan Mahadeva = Pi experiment So Where Are Memories Stored? Karl Lashley searched for the brain “engram,” physical “memory trace” in rats after they had run mazes from 1920 to 1955. Lashley believed: _____________________________________________________________________ Neural Basis and Emotional Impact For Memory Long Term Potentiation (LTP): refers to the _______________________________ ______________________________________. Is believed to be the neural basis for learning and memory. Process occurs naturally when we learn through association…after learning has occurred, neurons involved in process ________________________________________. Drugs that block LTP __________________________________. __________________________________________________________________ Stress hormones boost impact on learning. Storage Loss: Amnesia Amnesia __________________________________________ Depending on the damage or disease different kinds of memories can be d a m a g ed Amnesiac patients typically have _______________________________. Explicit Memory (declarative memory): _____________________ and experiences that one can consciously know and declare. My birthday is ……… Hippocampus’s Role in Explicit Memory Hippocampus: neural center located in limbic system that helps ______________________________ for storage….left and right hippocampus have different effects. Hippocampus’s Role in Explicit Memory Names, images and events Damage to the Left= ________________________________________ Damage to Right= _______________________________ Different parts of the brain house different memories Monkeys with Hippocampus damage had ___________________________________ Implicit Memory Other type of memory storage is known as: Implicit Memory (Procedural Memory): retention of things without conscious recollection. ______________________________________ Walking Riding a bike Cerebellum’s Role in Implicit Memory Cerebellum: helps facilitate associate _____________________________ ie classical conditioning. Cutting pathway to the cerebellum makes rabbits _____________________________________ Day 3- Storage, Retrieval and forgetting Retrieval: Getting Information Out Recall: a measure of memory in which the person must _____________________ learned earlier. Ex: _____________________________ Recognition: a measure of memory in which the person need only ________________ ________________________________________ Easier than recall Ex: ______________________________________ Retrieval Cues Priming: activation, often unconsciously, of particular _________________________. Missing child poster…. Kidnapped Tastes, smells,sights Context Effects Memory Retrieval: able to retrieve information better _____________ _________________________________________________________ Deja Vu Emotional/Mood Impact of Memory: 1. State-Dependent Memory: information is most easily recalled _______________ _______________________________________ it was learned in. Drunk 2. Mood Congruent Memory: tendency to recall experiences that are ____________ _______________________________________________________ Depressed ppl recall parents as rejecting , mean….. 7 sins of Memory 1.Absent Mindedness – __________________________ produces encoding failure 2.Transience- ______________________________________ 3.Blocking- unable to access stored info…._________________________________ 4.Misattribution- __________________________________ of the info. Suggestibility- the lingering effects of misinformation ________________________________ 6. Bias- _________________________________________ 7. Persistence- __________________________________________ Forgetting-Forgetting As Encoding Failure Information ________________________________________ Attention is selective ____________________________________________________ William James said that we would be as bad off if we remembered everything as we would be if we remembered nothing Change Blindness Penny Storage Decay – Retrieval Failure- Forgetting can result from _________________________________________ Forgetting As Interference Learning some items may disrupt retrieval of other information Proactive(forward acting) Interference _________ __ ____ __________ ___ ____ __________ ____ ___ ___ New Phone Number New schedule Retroactive (backwards acting) Interference _________ __ ____ __________ ___ ____ __________ ____ ___ ____ Teacher learning new names Take a break after learning Day 4- Memory reconstruction Motivated Forgetting Motivated Forgetting is the idea that _____________________________________. Repression: idea put forth by psychoanalytic theorists like Freud which states anxiety arousing thoughts, feelings, and ______________________________________________ Ex: ____________________________________ may be repressed and not be able to be actively recalled. Memory Construction Memory Construction refers to the idea that memories are NOT objective, recordings of the actual events we experience. ________________________________________________ and involve information filtering and interpretations. Memory Construction Affected By: Misinformation Effect: incorporating ___________________________________ of an event Source Amnesia: ____________________________________________ that we experienced, heard about, read about, or imagined (misattribution) Reagan and the movie, A Wing and a Prayer Memory Construction Overview People ______________________________ with plausible guesses and assumptions __________________________________ can create false memories Persistence and _________________________________________ Children's eyewitness recall Child sexual abuse does occur Some innocent people suffer false accusations Some guilty cast doubt on true testimony Children are fairly accurate when their memories are not tampered with Memory Construction Roediger and McDermott Brain Study False and true memories registered in the hippocampus _______________________________________________________ Processes speech sounds Memory Construction and Abuse Memories of Abuse Repressed or Constructed?
