Multistore Model Of Memory Flashcards
What does SR stand for in the context of memory?
Sensory Register
Sensory Register is the initial stage of memory where sensory information is stored for a very short duration.
What is the capacity of Short-Term Memory (STM)?
7 ± 2 items
This concept was introduced by Miller, indicating that the average number of items an individual can hold in STM is between 5 to 9.
What is the duration range of Short-Term Memory?
0.5 - 25 seconds
This range indicates how long information can be retained in STM without rehearsal.
What is the main idea of the Multistore Model of Memory?
Memory consists of three stores: Sensory Register, Short-Term Memory, and Long-Term Memory
Atkinson and Shiffrin proposed this model to explain the flow of information through different memory systems.
Who conducted the experiment involving the recall of a 12-letter grid?
Sperling
Sperling’s experiment demonstrated the capacity of the sensory register and the quick decay of visual information.
What does LTM stand for?
Long-Term Memory
Long-Term Memory is the system for storing information over extended periods, often indefinitely.
What type of memory did Clive Wearing demonstrate?
Split between declarative and procedural memory
Clive Wearing’s case illustrated how a virus could affect certain types of long-term memory while leaving others intact.
What was the finding of Peterson and Peterson’s study on memory?
Information decays quickly from STM without rehearsal
Their study on trigrams showed that recall decreases significantly after a short period without rehearsal.
What is chunking in memory?
Grouping information into larger, manageable units
Chunking helps increase the capacity of STM by organizing information into meaningful patterns.
According to Miller, what is the average digit span in STM?
7 ± 2 digits
This finding supports the idea that STM has a limited capacity, typically around 5 to 9 digits.
What are the three types of coding in STM identified by Baddeley?
- Acoustically similar words
- Acoustically dissimilar words
- Semantically similar words
Baddeley’s research showed that STM primarily uses acoustic coding, but semantic coding also plays a role.
Fill in the blank: The average recall time for digits in Peterson and Peterson’s study was _______.
18-30 seconds
This indicates how long information can be retained in STM before significant decay occurs.
True or False: Long-Term Memory has a limited capacity.
False
Long-Term Memory is generally considered to have an unlimited capacity.
