define: memory, short-term memory and long-term me
Memory: the structures and internal mental processes involved in regestering, storing and retrieving information.
short-term memory (STM): memories for immediate events; they last for a very short period of time unless they are elaborately rehearsed.
Long-term memory (LTM): Your memory for events that have happened in the past; they can last from 2mins to a lifetime.
define capacity, duration and encoding
capacity: the measure of the amount that can be held in memory.
duration: a measure of how long a memory lasts before it is forgotten.
encoding: the way the information is changed so it can be stored in memory.
differences between LTM and STM; encoding, duratio
- duration- very limitted (a memory in STM doesn't last very long)
- encoding-mainly encoded acoustically(sounds)
- capacity -very limitted (can hold 7+/- 2 chunks of info)
- duration- potentially unlimitted, theoretically memories in LTM could last a persons lifetime.
- encoding - tends to be encoded semantically (information represented by its meaning)
- capacity - potentially unlimitted
