features of memory stores Flashcards
what are the 6 AO1 points you must know for features of memory?
-Encoding (Coding)
-Capacity
-Duration
-Sensory Register
-Short-Term Memory (STM)
-Long-Term Memory (LTM)
What is meant by encoding in memory?
Encoding refers to how information is processed into memory.
Sensory register: by sense (e.g., visual, auditory)
STM: mainly acoustic
LTM: mainly semantic
What is capacity in memory?
Capacity is the amount of info each store can hold.
Sensory register: very large
STM: 7±2 items (Miller, 1956)
LTM: potentially unlimited
What is duration in memory?
Duration is how long information lasts.
Sensory register: ~0.5 seconds
STM: 18–30 seconds (Peterson & Peterson)
LTM: up to a lifetime (Bahrick et al.)
What is the role of the sensory register?
It’s the first store in the MSM. It takes in raw sensory input and holds it briefly. If attention is paid, it moves to STM.
What is the role of short-term memory (STM)?
STM holds a limited amount of information for short periods. Info can be lost unless rehearsed.
What is the role of long-term memory (LTM)?
LTM stores information permanently. With rehearsal, info from STM is transferred here and can be retrieved later.
