1
Memory We will begin with a story…
2
Fact, Fiction, and Forgetting On the next screen, you will see a list of words. Read them quickly:
3
Fact, Fiction, and Forgetting candycaramel soda popchocolate honeycake pieicing fudgecookie cotton candy
4
Fact, Fiction, and Forgetting Did the following words appear on the list you just read? candy, chocolate, sweet
5
Processes of Memory Encoding Put into memory Storage Retrieval Hold in memory Recover from memory
6
Atkinson-Shiffrin Model Environment Sensing Sensory Memory Long Term Memory Attention Short Term Memory Loss Retrieval Elaboration Loss
10

11
Short Term Memory
14
Long Term Memory (LTM) Depth of Processing Breadth of Processing-elaborative encoding Distributed Practicing Intentional Learning Incidental Learning
15
Measuring Memory Three measures typically used: Recognition Recall Relearning
21
Forgetting Failure to Encode Consolidation Failure Decay Interference Motivated Forgetting Retrieval Failure
23
Amnesia Retrograde amnesia –Infantile amnesia Anterograde amnesia
24
Tip of the Tongue The feeling of being on the verge of recalling something Often you can say what letter it starts with, or how many syllables it has
25
Reconstruction Piecing memory together from a few highlights, then filling in details based on what we think should have happened (schema)
26
False Memories Implanting memories Distinguishing fact from fiction –Reality monitoring –Source amnesia
27
Repressed Memories Memories of early sexual abuse
28
Eye Witness Testimony Relies greatly on reconstructive memory Influential in trials Accuracy is variable
29
Expertise Experts remember more details Probably due to use of elaborative encoding
30
Hypnosis Increases rememberer's confidence & amount of inaccurate information Doesn't increase memory accuracy
31
Factors Affecting Retrieval Serial Position Cues Environmental Context State-Dependence Stress and Anxiety
33
Stress and Memory Performance Stress LowModerateHigh
34
The Hippocampus Deep in the brain
35
The Frontal Lobe
37
Improving Memory Organization Spaced Practice Mnemonic Devices Method of Loci Peg-Word Method Acronyms Overlearning Recall Practice
38
Improving Memory: Tricks and Tools Improving memory retrieval –Mentally reinstate environment in which information was learned –Focus –Keep tying –Think of characteristics of the information sought –Use external cues
