Ch. 6 The Psychology of Memory (pt. 1) Think about this: Is it possible to have an identity without a memory? Extreme Memory Lapses Anterograde Amnesia – difficulty in learning new info after brain damage o Example: the movie 50 First Dates Retrograde Amnesia - difficulty in remembering events that happened before brain damage o Example: the movie The Bourne Identity Case Study: Clive Wearing (1938) o Virus destroyed his hippocampi (long-term memory structure in brain) o Long term memory is gone (to some degree) Can still remember how to play the piano and remember what day is birthday is on Case Study: Henry Gustav Molaison (“H.M.”) 1926-2008 o Sever epilepsy o Hippocampi removed o Can remember everything before the operation o Cannot create new memories o Mirror Drawing – doctors would have HM trace an image that was reflected in a mirror Very difficult to do Doctor records completion time and accuracy Does the same task every day (HM doesn’t remember doing it), and noticed that HM improves his skill every day Memory is not a Unitary System There are different types, facets, and subcomponents Information Processing System Sensory register short term memory long term memory o Must rehearse short term memory to make it to long term Sensory Register Sensory register: takes in information and hold onto it for just a split second Perception and attention determine what will be held in short term memory for further use Things that tend to grab our attention: o Size o Intensity Color/brightness/volume/smell o Novelty o Incongruity o Emotion Emotion drives attention, and attention drives learning Short Term Memory Frontal lobe Temporary storage of information Ex: trying to remember a phone number long enough to write it down or type it in Digit Span o Short term memory can hold about 5-9 digits – limited capacity “mental plate” – a plate can only hold so much stuff before things start falling off after adding too much food Easily disrupted – maintenance required How is it different from Working Memory? o Working memory manipulates things and moves them around o Ex: telling someone to remember a set order of numbers and then write them down backwards Working Memory Allows us to mentally manipulate info held in short-term memory Located in the frontal lobe Children have a less developed short-term and working memory because their frontal lobes haven’t fully developed Making It Stick Maintenance Rehearsal – saying things over and over again in your head until you remember it fully Chunking- grouping info together to make it easier to remember Elaborative Rehearsal – to remember info by associating it with a place that you are familiar with o EX: remembering a set of numbers – think about your house and walking through each room. And in each room, there is a number in the sequence Make a connection – associating new info with old info in long-term memory Psychologists recommend elaborative rehearsal and making a connection as the best methods of remembering Long Term Memory 3 types: o Episodic o Semantic o Procedural Episodic Memory o “I remember when...” o An “episode” of your life o Ex: remembering what you did on your last birthday; remembering where you parked your car Semantic Memory o Based on acquired facts that you know – ability to retrieve known facts and info o Ex: playing Jeopardy – trivia o Not based on personal experiences, rather, based on info that you’ve read or saw or learned about Procedural Memory o Performing a set of procedures typically not mediated by language o Ex: riding a bike, tying your shoes o Becomes automatic, even after not doing it for a long time o Almost like “muscle memory”
