Chapter 7: Memory
What is the testing effect?
- being tested on info is better than restudying - more apparent over time
how can you practice?
- make your own test questions - have friends quiz you - make flashcards
how does the storage process work
- storage happens via consolidation - neural connections that support the memory become stronger
What gets stored in long term memory?
-Exposure is not enough -Better memory for... Things you attend Things you process deeply Things that are personally important Things that are interesting
how does the encoding process work
1. Information comes from surroundings 2. The brain transforms information into a neural code
what areas of the brain are involved with memory
1. Prefrontal cortex 2. Temporal lobe 3. Amygdala 4. Cerebellum 5. Hippocampus
What is the three-part model of memory
1. Sensory memory 2. Short term memory 3. Long term memory
differences between short term memory and working memory
Short term: - storage only - tested with simple tasks Working: - storage and manipulation - tested with complex tasks
what is encoding
The processing of information so that it can be stored
What is sensory memory?
VERY briefly (less than 1 sec) stores sensory info close to its original sensory form - not everything reaches conscious awareness (requires attention)
what is amnesia
a partial or total memory loss
example of context dependent memory
a scuba diver who was taught words underwater recalled them better underwater than he did on land
what is working memory
active memory system that holds info and manipulates it for current use - part of the short term memory system (also short) - can involve info from STM or reactivated long term memory
what are retrieval cues
anything that helps a person recall info stored in LTM
What is episodic memory?
autobiographical memory - knowledge about the self - EX: remembering your 21st bday
What is chunking in memory?
breaking info up into meaningful units
what is elaborative rehearsal?
encoding info in more meaningful ways
what is state dependent memory
enhanced memory dependent on emotion - remembering sad things more easily when you are already sad
Subdivisions of explicit memory
episodic and semantic memory
what is encoding specificity
experiences during learning can affect what cues are helpful - Ex: piano - something that weighs a lot --> cue = heavy - something with a nice sound --> cue = music
what are the subdivisions of long term memory
explicit and implicit
What is the amygdala responsible for?
fear learning
what is interference
forgetting due to learning new info - either forgetting the new info or forgetting the old info
What is retrograde amnesia?
inability to access old memories
what is absentmindedness?
inattentive or shallow encoding of events - Ex: not paying attention to where you set your phone
What is the serial position effect?
items at the beginning and end of the list are more memorable
What is associative memory
knowing one stimulus predicts another - alters behavior and/or elicits a response - Ex: a dog hearing the treat bag
what is semantic memory
knowledge about facts: - independent from personal experience - EX: jeopardy questions, exams
what is explicit memory
knowledge we are aware of - involves conscious effort
What is deep processing?
level of processing that builds more meaning and leads to better memory - does it fit in this sentence? - is it useful on a deserted island?
What is retrieval?
recalling or remembering stored information when needed
what is bias
memories change to become consistent with current beliefs or attitudes - Ex: how much you did for a group project
what helps maintain items in the short term memory
rehersal
what is prospective memory
remembering to do something at some future time - Ex: remembering you have a meeting - often use tools like planners, phones, calendars
what is source monitoring?
remembering where you encountered something - Ex: recalling you learned Milgram's experiment in psych class
what is the physical location of memory
memory involves multiple regions of the brain (not all regions are equally involved)
what is maintenance rehearsal?
repeating an item over and over
What is procedural memory?
memory of skills and habits - muscle memory - Ex: riding a bike
What is short term memory?
memory storage that briefly holds small amounts of info - info lasts here for 20-30 seconds - holds 7 ± 2 "items" - requires work to maintain
what is implicit memory
memory without awareness - might not know you know - occurs without deliberate effort
what is misattribution
misremember when you encountered the info - thinking you remember info from someone other than the person who gave it to you
What is the cerebellum responsible for?
motor action learning and memory
What is anterograde amnesia?
no formation of new memories
Subdivisions of implicit memory
procedural, associative, and prospective memory
what is blocking
retrieval is blocked by a different memory - "tip of the tongue phenomenon" - Ex: forgetting someone's name **self cueing can help**
similarities between short-term memory and working memory
short and limited in size
What is shallow processing?
simple method of encoding - all uppercase? - does it rhyme?
What is the hippocampus responsible for?
spatial memory
what is memory
the nervous system's capacity to retain and retrieve skills and knowledge
What is consolidation?
the neural process by which encoded information becomes stored in the memory
What is long term memory?
the relatively permanent storage of info - relatively stable - nearly limitless - autobiographical, semantic info, etc
What is storage?
the retention of encoded information over time
what is a concept map
visual wat to organize info - starts with a central topic - create web of connected idea
what is context-dependent memory
where you are during encoding impacts retrieval
What is the prefrontal cortex responsible for?
working memory
What are the best ways to ace your tests?
1. distrbute your learning 2. practice 3. use concept maps 4. use verbal mnemonics 5. use visual imagery
what are the three stages of memory
1. encoding 2. storage 3. retrieval
what are the seven sins of memory
1. interference 2. blocking 3. absentmindedness 4. persistence 5. misattribution 6. bias 7. suggestibility
how can you distribute your learning
1. no cramming 2. read ahead 3. review notes between classes 4. study a little each day
what is persistence
continual recurrence of unwanted memories - Ex: PTSD
What is the temporal lobe responsible for?
declarative memory
what is suggestibility
development of biased memories due to misleading information - Ex: what happened in the car accident + smashed vs hit + estimate speed + was there broken glass - "remembering" events that did not happen
