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

short-term memory:

  • 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)

Long-term memory:

  • 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
