Memory - 8 Flashcards
DRM Paradigm
-human memory is more reconstructed in nature → everytime you remember information, it is not retrieved how it was stored, instead is a reconstruction or inference of prior experience
Memory follows: encoding, storage, retrieval
Retrieval cue
any piece of info that can be used to access other information that is stored in memory
2 Common Ways to Test Memory
- Free recall - both participants ability to remember items from encoding phase (generate items from yourself)
- `Recognition test - show a list of items and have to check if they remember them or not (old vs new)
Patient HM
chronic seizures, removed large portions of hippocampus on both sides of brain (linked to memories is hippocampus). He stopped having seizures but had anterograde amnesia → couldn’t remember new memories but had the same IQ, short-term memory was intact and could learn complex new motor skills
Short term memory
held for soon use but does not hold onto it unless transferred to long term
George miller
conducted people can remember about 7 numbers +/- 2 at a time
-items at beginning of list are more likely to be remembered as they have more time to be rehearsed
-latest items can also be well remembered
Serial position curve
Levels of processing principle
the more we try to organise and understand the material, the better we remember it
it’s possible that even the faintest of memories can be stored in the brain in some way
-memories that never happened can be implanted to people’s brains
→ recalling a memory is open to reconstruction
Central Executive:
Coordinates and manipulates the information stored in
the working memory and helps you to focus and sort info.
Chunking:
The process by which information is organized into sets of
familiar groups or categories of items. This can help increase the total
number of items held in memory.
phone number in chunks
Decay theory
the idea that forgetting occurs because memories naturally fade over time
Declarative/explicit memory
-abilityto store/retireve semantic and episodic memory
-Memories for factual
information (semantic memory)
-memories that are tied to a particular
place and time (episodic memory).
Echoic Memory:
Sensory memory for our auditory system.
Encoding:
How information initially enters into memory. A selective
process that is highly dependent on attention.
Encoding Specificity:
When we encode a particular item into memory, the
item is not processed in isolation but together with the surrounding context.
if you study for a test in a specific room, you will perform better on that test if you take it in the same room
