1. Chapter 8 Part II LONG TERM MEMORY RETRIEVAL FORGETTING

2. Step #2 – Storage Long Term Memory e.Drugs block the firing of the neuron, stopping the LTP, and disrupting storage. f. Hormones affect learning/memory formation during stress and emotional reactions. *Flashbulb Memory – a memory of an INTENSELY emotional experience. You relive it and rehearse it frequently, creating LTP. Flashbulb Memories

3. Step #2 – Storage Long Term Memory I.Two LTM Systems (Oliver Sacks) A.Implicit Memories –implied by our behaviors 1. Procedural –require muscle memory/cerebellum 2. Nondeclarative – we don’t talk about them, we just “remember” them long-term Reciting favorite songs… Conditioned response…. Pavlov/Slobber May I have some candy ____________?

4. Step #2 – Storage Long Term Memory B.Explicit Memories – Explicit because we “explain” them 1.Declarative - we talk about these memories a.semantic/Left Hemisphere Factual information, meaning b.episodic/Right Hemisphere Personal/Emotional/”Episodes” of our life 2.Hippocampus/Association Areas/Temporal Lobes

5. Photo Share DESCRIBE ONE: PROCEDURAL, EPISODIC, AND SEMANTIC MEMORY FROM YOUR PHOTO

6. Stage 2 – Storage Long Term Memory C.Future and Past 1.Prospective Memory Memory for something we intend to do out in the future. Remembering to remember I remember that I need to stop at the grocery store on the way home from school. 2.Retrospective Memory Content remembered from the past. Includes:Semantic Episodic Procedural

7. Step #3- Retrieval

8. A.Three types of retrieval: 1.Recall:fill-in-the-blank Close your eyes….. What are the four lobes of the brain and what does each do? What’s the name of that one movie with that one guy? 2.Recognition:matching, multiple choice, true/false Do you know who the person to your left is? 3.Relearning:review questions, take-home exam, rewind Relearn names…. (it takes 7 times) *You can NEVER over learn! You CAN under learn! *You are not relearning/retrieving if you never learned it to begin with. *What do you think is your strongest type of retrieval?

9. Step #3 – Retrieval Cues and Priming B.To retrieve information, we need CUES (noun). These HELP get our brain ready to retrieve the information by PRIMING (verb) it. In other words, we are accessing that memory system put together through LTP. 1.What primes us or acts as a cue? a. Context – Read the words out loud. Deja vu - Have you ever experienced? LTP – We “prime” the same memory system… In our experiment, what primed your contextual memory? Context = the situation, the surroundings, the environment where the information was originally learned. Context is the CUE to PRIME memory

10. Step #3 – Retrieval Cues and Priming b.State of Mind “State Dependent Memory” (state of mind) Stress/Adrenaline Sleepiness Intoxication Comic State of mind is the CUE to PRIME memory c.Mood - Mood Congruent Memories – How can I get mad? I’m so happy NOW! Emotion is the CUE to PRIME memory

11. Step #3 – Retrieval Repression A.Can we repress memories of past abuse? 1.Repression DOES happen, but it’s usually retrieved with CUES. 2.Incest DOES happen 3.Forgetting DOES happen 4.Recovered memories are common place, both good and bad. 5.Memories “recovered” under drugs and/or hypnosis are very unreliable. False MemoriesFalse Memories 6.Memories of things that happened before the age of 3 are very unreliable…. WHY? Infantile Amnesia Procedural Memories – First Semantic Memories – Require Language Episodic Memories – Require Self-Concept (last) 7.Memories real or false can be very emotionally upsetting.

12. Step #3 – Retrieval Repression B.So, does repression occur? What’s the verdict? Hard to prove Memories can “feel” real, even if they are not Be sensitive as a therapist All evidence shows that we forget rather than repress Memories prior to age three are unreliable

13. Step #3 – Retrieval Forgetting IV.Forgetting We forget because we fail to ENCODE. We forget because we fail to STORE properly. We forget because as we encode there is INTERFERENCE We forget because we are MOTIVATED to. (we ignore cues) We forget because we can’t access information……. A.RETRIEVAL failure 1.Perhaps there weren’t enough CUES a.Sensory Cues b.Mood or State of Mind c.Context

14. Step #3 – Retrieval Forgetting 2.May be caused by retrieval INTERFERENCE a.Proactive MnemonicP O b. Retroactive MnemonicR N Pro and Retro

15. Step #3 – Retrieval Memory Construction V.Memory Construction A.When you construct a memory, it can be: 1.Altered as it is ENCODED. 2.Altered as it is RETRIEVED. 3.Misdirected by your SCHEMA. 4.Misinformation Effect: (Loftus again!) – misdirection due to leading questions Loftis Misinformation Ted Talk 5.Source Amnesia (crazy cousin/Mrs. Fuhriman)

16. Step #3 – Retrieval Amnesia B.Amnesia - no memory construction or reconstruction 1. Eidetic Imagery (snapshot) Eidetic Memory 2. Pathology of Memory *Attached Article*What is pathology??? Retrograde Amnesia –Forget RIGHT before the accident/trauma. Mnemonic:VRRRRRROOM!! Anteretrograde Amnesia -- Forget AFTER the accident/trauma. Mnemonic:AAAAHfter!!

17. Step #3 – Retrieval Amnesia Hippocampal Amnesia *Video* -- Breakdown in storage from STM – LTM (Clive) Milner’s Syndrome –Remember everything up to a set point in time. Brain damage Karsakoff’s Syndrome – Chronic alcoholism, vitamin deficiency, lose recent and begins to recede back. Alzheimer’s --Impaired semantic memory system due to build up of “plaques and tangles” in the hippocampus and left hemisphere. Interference with neural transmission in memory areas.
