Topic 6: Memory Flashcards
Define memory
process of how we take something observed and convert it into a form we can store, retrieve, use
Process of memory
encoding - storage - retrieval
What is a memory?
MENTAL REPRESENTATION for something to be remembered = mental model of information
Sensory representation
5 senses eg visual image of a dog
Verbal representation
words, info, spelling, concepts, language eg info stored in words - concept of freedom
Motoric representation
memories of motor actions eg riding a bike
Information processing model of memory (standard)
stimulus - sensory register - short-term memory (STM) (rehearsal/retrievel) - long term memory (LTM) (retrieval)
Sensory registers/memory
Hold info about a perceived stimulus for a fraction of a second AFTER stimulus disappears
Sensory registers/memory - iconic storage
momentary storage VISUAL info
Sensory registers/memory - echoic storage
momentary storage AUDITORY info
Short-term memory (STM)
info from sensory reigsters that is ATTENDED to moves into STM (not all info attended to)
What is the capacity/duration of STM?
Capacity - small amount of info, ~7 items
Duration - short time, ~20-30 seconds
What happens if STM is rehearsed?
Info maintained in STM for longer
maintenance rehearsal + elaborative rehearsal - deep vs superficial learning
Long-term memory (LTM)
representations of facts, images, actions and skills - persists over a lifetime
works closely with working memory
contains info about our memory for experiences/info accumulated
What is the capacity/duration of LTM?
duration - potentially limitless
capacity - theoretically limitless
LTM MODEL
TYPE of knowledge - procedural memory + declarative memory (generic/semantic - general knowledge) & (episodic - specific events)
WAY knowledge is EXPRESSED - implicit memory + explicit memory (recall) & (recognition)
Types of explicit memory
Recall - conscious recollection of info from LTM
Recognition - identification of something previously seen/learned
Types of implicit memory
Priming - previous experience changes response without conscious awareness
Classical conditioning - associating response ith a stimulus
LTM Model (picture)
Evolution of memory model
Memory no longer thought of as serial processing modelling
Comprise number of modules
Interdependent (parallel processing) - not always conscious or retroactive
