Topic 3-memory Flashcards
what are the two parts of sensory memory?
Iconic: lasts 0.3 seconds and limited capacity
Echoic: lasts 3-4 seconds, unlimited capacity
phonological loop meaning
storage system for auditory information
Visuospatial loop meaning
Storage system for visual information
central executive meaning
- switches between attention fron tas to task
- decides what material needs to be retrieved or commited to long term memory (screens out whats irrevulatant). makes links and claculations
episodic buffer meaning
acts as a filter for auditory and visual information
-bridge between long term memory and central executive
whats the LOP model of memory? (levels of processing)
- That memory is a continuous dimension in which its encoded related to the ease it can be retireved
- The deeper the processing of information, the greater chance of it being retrieved
What are the types of LOP encoding and what do they do?
example: learning words
Structural: (shallow feature) words learnt by physical feature (eg upper case A)
Phonemic:(moderate) learnt by how the word sounds
Semantic:(deep) learnt by the meaning of the word
implicit and explicit memory meaning
Implicit: Procedual memory, motor skills, classical conditioning (unconscious)
Explicit: declaritive memory, general knowledge and facts, episodic memory (personal experiences)
(conscious)
Whats the role of the hippocampus in memory formation and storage?
-Memory formation: The hippocampus is involved in establishing the background and context for each new memory.
Storage: The process of permaneant storage of memory transfers into relevant parts of the bain for permaneant storage in long term memory.
whats the role of the cerebellum in forming implict memories?
- activates the neural system to retrieve a memory
- This enables automatic performance of tasks and motor skills
Whats recall?
the retrieval of stored information
whats recognition?
the process of retrieval that requires identification of a correct response from a group of alternatives
whats relearning?
Learning something again after its been commited to the memory
how is memory lost through encoding failure?
- When there is lack of attention
- A memory is thought to be forgotten but was never encoded in the first place
how is memory lost through retrieval failure?
-Inability to retrieve material due to an absense of the right cues or a failure to use them
