Journal prompt: Write down everything you did yesterday that did NOT involve memory. Overview of the multisystem model of memory I. Traditional theories of memory A. Information Processing model: memory storage compared to computer 1. Encoding 2. Storage 3. Retrieval Studying Memory: Information Processing Models Keyboard (Encoding) Disk (Storage) Sequential Process Monitor (Retrieval) 7 Overview of the multisystem model of memory I. Traditional theories of memory B. Three stages of memory Atkinson & Shiffrin (1968) 1. Sensory 2. Short-term memory 3. Long-term memory Information Processing Frank Wartenberg/ Picture Press/ Corbis Bob Daemmrich/ The Image Works Bob Daemmrich/ The Image Works The Atkinson-Schiffrin (1968) three-stage model of memory includes a) sensory memory, b) short-term memory, and c) long-term memory. 9 Modifications to the Three-Stage Model 1. 2. Some information skips the first two stages and enters long-term memory automatically. Since we cannot focus on all the sensory information received, we select information that is important to us and actively process it into our working memory. A newer understanding of short-term memory that involves conscious, active processing of incoming auditory and visual-spatial information, and of information retrieved from long-term memory. 10 Overview of the multisystem model of memory II. Modern theory of memory: Memory is a collection of systems working independently of one another A. Types of Memory 1. Declarative 2. Non-declarative B. Evidence 1. People with damage to brain showing patterns of amnesia still have a working memory and nondeclarative memory. 2. People have impairments in episodic memory, but not semantic memory. “Understanding the Mysteries of Memory” Discovery Learning (1996) • implicit and explicit memory • savant syndrome • traumatic memory • short term memory loss • long term memory loss • flashbacks • “flashbulb memories" • mistaken identification • suggested memories • trauma induced amnesia • Alzheimer’s disease Memory alternative video This is a program about memory failures using real case studies. Also, you may watch the alternative video for case studies. Assignment: • Write an extended journal entry about one of the conditions discussed in the film. • Use the individual’s name and describe specific situations of memory failure. • Use your text to supplement your understanding of memory loss. • Conclude with your personal reaction to the case study. Length:3 well-written paragraphs Can be typed. Cite sources. All original work, please. AP Psychology Lesson 1/7/2015 • Journal prompt: Storing Memories in the Brain. • Finish video “Understanding the Mysteries of Memory” After notes • Notes: Biological Basis of Memory • Attention: Vocabulary Quiz Monday 1/12 – Encoding and Storage – Pages 327-345 • Homework: Psych Sim – Trusting Your Memory – Forgetting – Short Term Memory AP Psychology Journal prompt 1/7/2015 2.2 Identify and explain biological processes related to how memory is stored. p. 340-341 In their experiments with sea slugs, what did Kandel and Schwartz learn about the neural basis of learning? How does the brain store our memories? • Old idea of flashbacks triggered by brain stimulation • Loftus’ research (1980) refuted • Lashley’s research (1950) did not find cortical localization of memory The brain • Synaptic changes – Long Term Potentiation LTP • Stress and hormones • Hippocampus • Cerebellum Synaptic Changes Both Photos: From N. Toni et al., Nature, 402, Nov. 25 1999. Courtesy of Dominique Muller Long-Term Potentiation (LTP) refers to synaptic enhancement after learning (Lynch, 2002). An increase in neurotransmitter release or receptors on the receiving neuron indicates strengthening of synapses. 17 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 18 Storing Implicit & Explicit Memories Explicit Memory refers to facts and experiences that one can consciously know and declare. Implicit memory involves learning an action while the individual does not know or declare what she knows. 19 Hippocampus Hippocampus – a neural center in the limbic system that processes explicit memories. Weidenfield & Nicolson archives 20 Anterograde Amnesia After losing his hippocampus in surgery, patient Henry M. (HM) remembered everything before the operation but cannot make new memories. We call this anterograde amnesia. Anterograde Amnesia (HM) Memory Intact No New Memories Surgery 21 Implicit Memory HM is unable to make new memories that are declarative (explicit), but he can form new memories that are procedural (implicit). A B C HM learned the Tower of Hanoi (game) after his surgery. Each time he plays it, he is unable to remember the fact that he has already played the game. 22 Cerebellum Cerebellum – a neural center in the hindbrain that processes implicit memories. 23 AP PSYCHOLOGY LESSON 1/12 • Journal Prompt: Ebbinghaus • Videos “The Brain” • Memory Notes • Quiz Encoding & Storage P. 327-345 Rehearsal Effortful learning usually requires rehearsal or conscious repetition. http://www.isbn3-540-21358-9.de Ebbinghaus studied rehearsal by using nonsense syllables: TUV YOF GEK XOZ Hermann Ebbinghaus (1850-1909) 25 Rehearsal The more times the nonsense syllables were practiced on Day 1, the fewer repetitions were required to remember them on Day 2. 26 AP PSYCHOLOGY JOURNAL 1/12 Encoding 3.1 Students are able to discuss strategies for improving the encoding of memory. • Journal prompt: p. 331 What do Ebbinghaus’ experiments on memory retention suggest about the effect of overlearning? AP Psychology Lesson 1/14 • Journal Prompt: déjà vu • Forgetting • Library to do Psych Sim activities Déjà Vu Déjà Vu means “I've experienced this before.” Cues from the current situation may unconsciously trigger retrieval of an earlier similar experience. © The New Yorker Collection, 1990.
