Memory Flashcards
Draw/describe the multistore model
accurate drawing with all key words
(environmental stimuli —> sensory register –> STM—> rehearsal—->LTM
How is STM stored/coded
Auditory
How is LTM stored/coded
Semantic
What is the duration of LTM
lifelong
What is the duration of STM
18 seconds
What is the capacity of LTM
infinite
What is the capacity of STM
5-9
Define sensory register
The place where information is held at each sensor- eyes, ears, nose etc and the corresponding are of the brain. large capacity
Define Attention
If a persons attention is focused on one of the sensory stores then the data is transferred to STM
Define STM
information is held in the STM so it can be used for an immediate task.
Define maintenance rehearsal
Repetition keeps information in the STM but will eventually create a long term memory.
Define LTM
The storage of information over an extended period
Define retrieval
The process of getting information from the LTM, involves the information passing back through the STM
Evaluate the multi-store model
Strengths
1. Brain damage case studies, show LTM & LTM are separate
2. Brain scans, LTM shows activity in the Hippocampus, STM shows activity in the Prefrontal Cortex
weaknesses
1. Craik & Lockhart discovered that elaborative rehearsal is more effective than maintenance rehearsal
Evaluate the Working memory model
Strengths
1. Dual tasks, evidence for the central executive
2. Brain damage case studies, evidence for separate visuo-spatial and phonological loop systems
weaknesses
1. Lack of information on the central executive, the concept is vague and does not explain anything, some critics think it cannot be a single central executive but several
What are the features of the working memory model
Phonological loop, Episodic buffer, Visuo-spatial sketchpad and Central executive
What is the central executive
Monitors and co-ordinates all the other mental functions in working memory
What is the phonological loop
Codes speech sounds in working memory, typically involving maintenance rehearsal
What is the episodic buffer
Receives input from many sources, temporarily stores this information, and then integrates it in order to construct a mental episode of what is being experienced
What is the visuo-spatial sketchpad
Codes visual information in terms of separate objects as well as the arrangement of these objects in ones visual field
what is the working memory model
An explanation of the memory used when working on a task, where each store is qualitatively different
what is the multistore model
An explanation of memory based on three separate memory stores and how information is transferred between these stores
