Memory
and Learning: Memory Introduction
1) Memory and learning inextricably
interwoven processes: can't have one system without the other
Learning
without memory without learning;
Without
memory: Conditioned Stimuli
Consequences
Model activity
No language
No consciousness no humanness

2) History: In search of an
Engram
Karl Lashley and
the Engram: neural circuitry of leaning and
memory trace and
localization
No
memory at all
Vast
improvements: encephalitis, Korsakoff's syndrome, and HM
Memory
involve storing information over time (1 second to a lifetime)

3 obstacles=accuracy
1)
encoding or acquisition: perceive item and record
2)
storage hold information for later storage
3)
retrieval locate and use

The Atkinson-Shiffrin
Model
The Atkinson-Shiffrin Model
This is a structural model which suggests that people have their memory stored in sensory store, short-term and long-term memory. Sensory memory results from some form of stimulation and can be classified as either iconic memory or echoic memory. Short-term memory is temporary and it is similar to attention. Long term memory is permanent and it is generated from understanding of meaningful or emotional 'material'. It is more complicated and can be classified as explicit versus implicit; conscious versus unconscious; declarative versus or non declarative.

- This approach illustrates the different impact on memory by different level of processing through verbal, acoustic or semantic of the information.

 |
 |
- This model classified memory into episodic, semantic and procedural depending on the nature and content of information stored.
|
|
|
- This model perceived memory exhibiting multiple links to the network of cognitive process, biological process, animal behaviour, mathematical and so on.
