What is the duration of long-term memory in the Atkinson-Shiffrin Stage Model?
AUp to thirty seconds with limited storage capacity
BUp to a lifetime with unlimited storage capacity
CLess than one second with very large storage
DUp to twenty four hours with moderate capacity
Answer & Solution
Correct answer: B. Up to a lifetime with unlimited storage capacity
1. Fig. 6.1 summarises the three memory stores with capacity and duration tags.
2. Sensory memory has large capacity but duration less than one second.
3. Short-term memory has small capacity and duration less than 30 seconds.
4. Long-term memory is shown as having unlimited capacity and duration up to a lifetime.
5. Hence the LTM duration tag is up to a lifetime.
