Memory super memorist: 20 The persistence of learning over time through the storage and retrieval of information.
Was it easy or hard? • It depends on several things…. • If you like Disney movies? • When was the last time you have seen the movie? • Are people around you being loud so you cannot concentrate?
Take out a piece of paper…. . • Name the seven dwarves…. . Now name them…. .
Recall vs. Recognition Recall • you must retrieve the information from your memory • fill-in-the blank or essay tests Recognition • you must identify the target from possible targets • multiple-choice tests
The Memory Process crash course Three step process…. 1. Encoding: The processing of information into the memory system. 2. Storage: The retention of encoded material over time. 3. Retrieval: The process of getting the information out of memory storage.
Three Stage Theory of Memory
Sensory Memory replication of Sperling's experiment • A split second holding tank for ALL sensory information. – Iconic (Visual) – Echoic (Auditory)
Short Term Memory • The stuff we encode from the sensory goes to STM. • Events are encoded visually (images), acoustically (sounds) or semantically (meanings). • Holds about 7 (plus or minus 2) items for about 20 seconds. • We recall digits better than letters.
Transferring from STM to LTM • Chunking - organizing items into familiar, manageable units • Mnemonic Devices 1 -4 -9 -2 -1 -7 -7 -6 -1 -8 -1 -2 -1 -9 -4 -1 "Mary Very Easily Makes Jam Saturday Unless No Plums. " • Rehearsal – repetition, repetition
Long Term Memory • unlimited storehouse of information • Explicit Memories (Declarative) – Facts Memorized (Semantic) – Events / Experiences (Episodic) • Implicit Memories (Nondeclarative or Procedural) – Skills – Example: how to ride a bike, shoot a basketball
Storing Memories - Encoding Effortful Processing • done actively, “with effort”, on purpose • Studying for a test • Completing AP Psych reading assignment • Drilling with AP Psych flashcards Automatic Processing • done passively, “without effort”, by “accident” • Remembering what you ate for breakfast this morning • Remembering the score of sporting event • Remembering who you first spoke to today
Storing Memories - Encoding • Amnesia - generally, the loss of memory • The Physical Basis of Memory – No one area houses memories – Ongoing Electrical Activity – Synaptic Changes • Long-term Potentiation (LTP) – increase in a synapse’s firing potential after stimulation (engram) • program 17 • modern example
Encoding Processes • Visual Encoding: the encoding of imagesexample • Acoustic Encoding: the encoding of sound • Semantic Encoding: the encoding of meaning ü the most effective ü encoding with multiple process types is even more effective
Memory Strategies start @ 7: 04 • Mnemonic devices are strategies to improve memory by organizing information – Method of Loci: ideas are associated with a place or part of a building example – Peg-Word system: peg words are associated with ideas (e. g. “one is a bun”) – Word Associations: verbal associations are created for items to be learned
Chunking & other methods • Organizing items into familiar, manageable units. • Often it will occur automatically. # 1 -4 -9 -2 -1 -7 -7 -6 -1 -8 -1 -2 -1 -9 -4 -1 Do these numbers mean anything to you? Chunk- from Goonies 1492, 1776, 1812, 1941 how about now?
Chunking Write down as many of the states of the US as you can remember!
Take out a piece of paper and name all the Presidents
Encoding Information • Serial Positioning Effects – the tendency for recall to be affected by the order of encoding – Primacy Effect –more likely to recall items at the beginning of a list – Recency Effect – likely to recall items at the end of a list – What else influenced your ability to recall?
Serial Positioning Effect • Our tendency to recall best the last and first items in a list. Presidents Recalled If we graph an average person remembers presidential listit would probably look something like this.
Encoding – The Spacing Effect • distributed study or practice yields better long term retention • cramming is minimally effective ü What, then, would be good strategies for preparing for AP Psych tests? ü For the AP Exam in the spring?
The Context Matters!!! crash course • Flashbulb Memories – a clear memory of an emotionally significant moment or event • Mood Congruent Memory – the tendency to recall experiences that are consistent with your current mood • State Dependent Memory – memory that is recalled under the consciousness conditions it was formed
Memory Construction • Memories are not always what they seem. • Misinformation Effect – incorporating misleading information into one’s memory of an event • Elizabeth Loftus
Misinformation Effect Depiction of Accident Leading Question: About how fast were the cars going when they hit each other?
Misinformation Effect Leading Question: About how fast were the cars going when they smashed into each other?
Forgetting – Encoding Failure
Which is the Right Penny? AUTOMATIC ENCODING (From Nickerson & Adams, 1979)
Forgetting – Retrieval Failure • Retroactive Interference: recent information blocks out old information. • Proactive Interference: previous information blocks out new information. Getting a new bus number and forgetting old bus number. Calling your new girlfriend by old girlfriend’s name. Clive Wearing
• Repression – Freud’s concept of the basic defense mechanism that banishes from consciousness anxiety arousing thoughts, feelings, and memories
Forgetting - Storage Decay • Even after encoding something well, we sometimes forget it. • Herman Ebbinghaus’ experiments with non-sense syllables – Showed the memory fades quickly, but then the speed at which it fades levels out.
Ebbinghaus’s Forgetting Curve
Types of Amnesia Clive Wearing • • Causes: Brain Damage, Shock, Repression, Stress and Illness Amnesia is forgetting produced by brain injury or trauma – Retrograde amnesia refers to problems with recall of information prior to a trauma – Anterograde amnesia refers to problems with recall of information after a trauma – 50 1 st dates trailer – Infantile Amnesia: Before 3 years old – Source amnesia-where did I hear or read that? ?
Significant People - Memory George Miller – Research on Short-term Memory Capacity – “The Magical Number Seven, Plus or Minus Two” (1956, Harvard) • established 7, + or – 2 as the limit of storable information • also first developed the concept of “chunking” to aid in memory retention
