Week 8 : Models of Memory Flashcards
What are the laws of repetition?
little and often makes for better retention
What are the 3 corre memory processes
encoding, storage and retrieval
What is the multi store memory model?
sensory memory, short term memory and long term memory
What happens in sensory. memory?
sensory input goes in and lasts for millisecond - seconds
What happens in the short term memory stage?
attention to sensory input, lasts for seconds to minutes
What happens in the long term memory stage?
storage and retrieval of the information that is pay attention to, lasts from days to years
What is the sensory memory store?
Its function is to have sensory information in the brain so we can attend to it
What is the capacity of the SM store?
Large amount of information is held in the ionic memory, declines rapidly
What is ionic memory?
Vision
What is the function of short term memory?
To store information we attend to consciously
What is the duration of short term memory?
Lost within 15-20 seconds if not rehearsed. The bigger delay the more information lost
What does interference mean?
Information that interfere/interrupts the information trying to be learnt, information is less likely to be held in the long term memory/more likely to forget
What are some criticisms of the STM model?
Information doesn’t need to be processed consciously
What is the working memory?
Mental workspace which is the basis of thought
What is the solution to the STM model?
A four component working memory model
What are the four components?
Central Executive, Phonological loop, Episodic buffer and Visual-spatial sketch pad
What is the central executive?
Attentional system that maintains tasks and goals
What is evidence for CE?
Dysexecutive syndrome
Alzheimer’s
What is Dysexecutive Syndrome?
Perseverance utilisation behaviour and catatonia is impaired.
What is the episodic buffer?
integrates information into single complex episode, it can hold 4 pieces of information in multidimensional code
What is the phonological loop?
Storage for information like and similar to speech
What is the evidence for the phonological loop?
Phonological similarity effect, word length effect, articulatory suppression effect
What is the phonological similarity effect?
items in the phonological store based in phonological code
What is the word length effect?
Memory for longer words in less than memory span for shorter words
What is the articulatory effect?
Worse performance when you have two thing at the same time
What is the visual-spatial sketchpad?
Responsible for mental image and spatial movements
What is visual cache?
The What in memory
What is the inner scribe?
The where in memory
Inner scribe: What is its function?
construction and maintenance of mental images
