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
HM retrograde amnesiac/age
27/hippocampal lesion
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)
S-R vs Cognitive.
Information processing cognitive has won the day Atkinson and Shiffrin (1968)

3) Elaboration's on Atkinson
and Shiffrin (1968)
Stage model and information
processing:
Processing stages:
surmount 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.
