Ch 7 Memory
Hook
H.M.
Case Study
- Of the many abilities that make up what we know as memory, which did H.M. lose and which did he retain?
- Do you think the surgery that cured H.M. of seizures made his life better?
7.1 Memory classifications & Processes
- Memory is encoding, storing & retrieving info.
7.1 Memory Classifications & Processes
3 Kinds of Memory
- Episodic memory- specific event
- Semantic memory- facts, words & concepts
- Implicit memory- things that are implied & not clearly state... practiced skills & learned habits
Three Kinds of Memory
Encoding
- translation of info into a form that can be recalled
- first stage of processing info
- visual
- acoustic
- Semantic code- info in terms of its meaning
Encoding
Storage
- maintenance of encoded info
- 2nd process of memory
- Maintenance Rehearsal
- mechanical or rote repitition
- more time spent on it, longer remebered
- does not connect info to past learning
- Elaborative Rehearsal
- relate to info you already know
- elaborative rehearsal
Storage
Retrieval
- locating store info & reurntning it to consious thought
- 3rd stage of processing info
- Context Dependent Memory
- info that is more easily retrieved in the context or situation in which it was stored
- State Dependent Memory
- retrieved because the mood in which they were originally enconded
Retrieval
3 Stages of Memory
- Sensory input
- Short-term or working memory
- long-term memory
7.2 Three Stages of Memory
Sensory Memory
- 1rst stage of info storage
- consists of immediate, initial recording of data
- Iconic memory- mental pictures
- Eidetic imagery- ability to remember visual stimuli over long periods
- Echoic memory- mental traces of sound
Sensory Memory
Short-term Memory
- Primacy & Recency Effects
- Chunking
- Interference
Short Term Memory
Long-Term Memory
- 3rd stage of memory capable of large & relatively permanent storage
- Memory as Reconstruction
- not recorded & played...reconstructed
- shape memories according to personal/ individual ways which we view the world
- remember things in accordance w/our beliefs & needs
- Schemas
- mental representations that we form of the world by organizing bits of info into knowledge
- influence ways we perceive things
Long Term Memory
Forgetting & Memory Improvement
- recognition, recall & relearning
- failure of any of these results in forgetting
7.3 Forgetting & Memory Improvement
Forgetting
- can occur at any of the 3 stages of memory
- info encoded in sensory memory decays almost immediately
- short-term memory last 10-12 seconds
Forgetting
Basic Memory Tasks
- Recognition
- identifying objects or events that have been encountered before
- Recall
- bringing something back to mind
- you do not immediately recognize something you have come across before
- you have to "search" for it & possibly reconstruct in your mind
- Relearning
- learning something a second time
- usually in less time than it was originally learned
Basic Memory Tasks
Different Kinds of Forgetting
- Repression
- forgetting thing of purpose (painful & unpleasant)
- Amnesia
- severe memory loss often caused by trauma to brain
- retrograde amnesia- events leading up to traumatic event
- anterograde amnesia- events after trauma
- Infantile amnesia- before 3 years old
Different Kids of Forgetting
Improving memory
- Drill & Practice
- Relate to Existing knowledge
- Form Unusual Associations
- Use Mnemonic Device
