Memory 3/15/1603/15/2016°Memory – the persistence of learning over time°°The Computer information Processing ModelEncoding – getting information into our brain oDo this by responding to the environment and by paying attention to somethingConsolidation – organizing & preparing for storage – effortfuloIf you don’t make an effort it wont go to the next partStorage – retaining information over time oEx. Leaving water in an ice tray in the freezer for a while until it turns to ice Retrieval – getting information back out°Information Processing: Atkinson & Shiffrin Model Dual-store first proposed by William James in 1890oClaimed Short-term and long-term memory are different Information-Processing Model oProposed by Atkinson & Shiffrin in 1968 with three memory stores, organized by duration Modified by Baddeley to include working memory 1986oBaddeley added working memory, central executive & 3 typesof short term memoryo***ASK AMANDA FOR THE PHOTO OF THE CHART°3 Kinds of Memory: Sensory Register
oAfterimage or echo oEnvironmental information picked up and transformed by sensory receptors oIconic – Visual oEchoic = Auditory Short term Memory oHolds a few items briefly oLimited capacity (7 + or – 2)oInterference prone oFound in the PFC – Prefrontal CortexoMr. Digit Man oAssessment of short term memory –digit span oDigit Memory Span: Age: # of digits 2-3 yrs 25 yrs 4 7 yrs 510 yrs 6 13 yrs 6-7 oWorking memory (another function of short term)Is the active form Changes information into another form
oExecutive consolidator control function that pulls all of the sensory channels into one episodic thingLong term Memory oHolds information together for hours, days or yearsoRelatively permanent o“unlimited capacity”oTwo long term memory systems:Conscious: Explicit – declarative Available to our awareness You can tell me exactly what you know Hippocampus Un-effortful, automatic processing of hippocampusoSpace, time and frequency Semantic (1stlvl)Meaning, facts without reference to time or place of learning EpisodicPersonal, specific experience at a particular time, in a particular spaceUnconscious: Implicit Procedural Motor“Muscle memory”Skills
Balance and Equilibrium Cerebellar °Recognition vs. Recall Snow white and the Seven DwarfsoHappy oSleepy oDocoSneezy oGrumpy oDopey oBashfulRecognition is better because it is easier, more efficient in remembering the most for accessing memoryAge Progression: o4 yr old: Recall - 2-4 items Recognize: 11-12 itemso8-10 yr old: Recall: 6-9 items Recognize: 12 items oAdult: Recall: 10-11 items Recognize: 12 items Memory is organized bySound (phonetically)Letter(visually)Meaning (semantically)Remembering mistakes related to these categories
°Memory Failure Encoding – acquisition failure oRequires attention and effort o
