Unit 9; Memory Flashcards
Memory
A pattern recognition skill driven by prior learning + experience
The DRM paradigm
Give a list of related words then ask you if a similar word was there (ex. say types of insects, was a ladybug there).
Commonsense analogies fall short bc memory is reconstructive
Encoding
Study phase
- information initially enters memory
- selective based on attention
Storage
Retention interval
- record of memory is retained over time
- not fixed, flexible and can be modified over time
Retrieval phase
Test phase
- recovering stored info when needed
- dependent on retrieval cues or current similar experiences that evoke memories
Retrieval cue
Any piece of info that can be used to access other info that is stored in memory
Sensory memory
The transient maintenance of perceptual and physical info from the very recent past
Free recall test
- few retrieval cues provided
- generate items yourself
ex. short answer
see if you remember things from the encoding phase
Iconic memory
Visual info sensory memory
lasts 0.5 sec
Echoic memory
Auditory info sensory memory
lasts 4 sec
Haptic memory
Tactile / touch info sensory memory
lasts 2 sec
Recognition test
- items listed, asked if old or new
- confirm validity of given items
ex. multiple choice
see if you remember things from the encoding phase
Patient H.M.
had seizures
1953 - hippocampi removed from brain
= less seizures
= amnesia, normal IQ, short term memory, can learn complex motor skills
Multi-store model
stimuli/imput
short term memory
- rehearsal
long term memory
Short-term memory
Info selected from sensory memory enters consciousness and is maintained in the short-term or working memory buffer
lets you keep a transient record
can be held longer with uninterrupted rehearsal
Short term memory capacity
7+/- 2 chunks
can increase if grouped into meaningful chunks
ex. familiar groupings of chess pueces
Chunking
Info is organized into familiar groups/categories of items
Working memory model
Modern understanding of short-term memory
includes phonological loop + visuospatial sketchpad+ buffer
Episodic buffer
Draws on long term memory and phonological loop and visuospatial sketchpad to remember specific past episodes
Phonological (articulatory) loop
Stored phonological info over a brief period
ex. repeating a phone # in your head
Visuospatial sketchpad
Stores visual info over a brief period
ex. mental map
