Importance of memory
Impossible to learn without memory.
Learning is central to our survival.
Allows us to adapt and learn.
Remember the previous context of a present situation to learn.
Relevant to psychology
What is memory?
An active system that records, stores and later retrieves experiences and
information.
Memory is: process and place
Memory processes (ECSR) “everything can seem right”
1) Encoding
2) Consolidation
3) Storage
4) Retrieval
1) Encoding (keyboard)
Converts sensory information into a form that the brain can use.
Translating it into a neural code
(just like a laptop converts what you type into a code for the laptop to
process)
Rehearse information over and over.
Elaborate on the meaning of the information.
Automatic encoding: people unconsciously notice and remember things .
(nude pumps)
+ flashbulb memories: unexpected event or episode in your life that has
strong emotional associations. (Bathroom door embarrassment).
2) Consolidation
Recent learned experiences are transformed into long term memories.
, Something that happens over time to make memories last:
Structural and chemical changes in the nervous system.
3) Storage (hard drive)
Retaining information over time, the time the information is held will differ.
Like saving information in a hard drive.
4) Retrieval (opening a file on a computer)
Processes that access stored information.
Getting info you know out of storage.
Like opening a file on a computer.
Models of memory
Information processing model
Parallel distributed processing model
Levels of processing model
1) Information processing model:
A metaphor inspired by advances in computer technology.
The mind as a system that processes information.
Encodes, stores and retrieves information rather like a computer system
However:
Human memory is more prone to error.
Human memory is more ‘constructive’.
It can ‘remember’ events that never occurred.
2) Parallel distributed processing model
Memory as a simultaneous process.
Creation and storage of memories taking place across a series of mental
networks ‘stretched’ across the brain.
Simultaneous processing allows people to retrieve different accepts of a
memory all at once.
Facilitates much faster reactions and decisions.
3) Levels of processing model
Length of time = depth of processing
All the models have some truth to it:
