Memory Chapter Nine
2
What is Memory? Maintenance of learning over time What good is remembering if you can’t recall it? Declarative, Procedural, Episodic Flashbulb Memories Information Processing Encoding Storage Retrieval Sensory Memory Short-Term Memory Long-Term Memory Sensory Memory Short-Term Memory Long-Term Memory
3
Encoding Automatic (Implicit) vs. Effortful (Explicit) ProcessingImplicit Rehearsal Effects Maintenance Rehearsal Maintenance Rehearsal Interference Elaborative Rehearsal Elaborative Rehearsal Ebbinghaus Forgetting Curve Forgetting Curve How we encode Distributed Rehearsal Spacing Effect Serial Position Effect Primacy and Recency Effect Graph Graph
4
What we encode Semantic Encoding Organizing Chunking Chunking Hierarchies Hierarchies Acoustic Encoding Visual Encoding Mnemonics Peg Word Mnemonic
5
Storage Sensory Memory Iconic Memory Eidetic Memory Echoic Memory Short-Term Memory Miller’s Magic Number 7+2 Maintenance Rehearsal Long-Term Memory Effectively Limitless
6
Retrieval Recognition vs. Recall Retrieval cues Tip-of-the-Tongue Tip-of-the-Tongue Semantic priming Context Effects Context Dependent Memory State Effects State Dependent Memory Mood Congruent Memories Stroop Effect Stroop Effect
7
Biology of Memory “Memory is Reconstructive Not Reproductive” Lashley (1950) Removed cortex of rat’s who had learned a maze Penfield (1969) Motor Cortex stimulation Doty (1998) Memory “defies comprehension” Synaptic Changes Aplysia – release of serotonin Long-Term Potentiation (LTP) more receptors more NT
8
More Bio Stress Hormones Release of these hormones improves memory Flashbulb memory Implicit (Procedural) & Explicit (Declarative) Memories Oliver Sacks Jimmie & Anterograde Amnesia These people can learn procedures, but not recall learning them!! Yes, this is Memento! Retrograde Amnesia
9
Brain Structures and Memory Hippocampus Lateralized like the Hemispheres!! Amygdala Frontal Lobes Coordinate various structures Cerebellum Thompson et al Found path from Cerebellum to brainstem for creating an association
10
Forgetting Schacter’s Seven Principles Forgetting Absent-Mindedness (Inattention) Transience (Decay) Blocking (Tip of the Tongue) Distortion Misattribution Suggestibility (Loftus) Suggestibility Bias Intrusion Persistence (NOT being able to block out a painful memory)
11
Forgetting Encoding Failure Pennies, Letters on the Phone etc... Storage Decay Storage Decay Ebbinghaus (1885) Retrieval Failure Proactive vs. Retroactive Interference Proactive vs. Retroactive Interference Repression?
12
Memory Construction Memory Is Reconstructive NOT Reproductive Misinformation Effect Imagination Effect False Memory Syndrome (FMS) False Memory Syndrome False Memories actually “light up” different parts of the brain!! Hippocampus lights up equally – actual memories light up the left temporal lobe, but false memories did not!! Eileen Franklin Children and Memory Accuracy
