Storage in Long Term Memory
Procedural Memory system: a memory for how to do things, a memory for skills
and actions. Example: riding a bicycle, how to tie your shoes, driving a car.
Declarative Memory system: memory for information and facts:
a) Semantic memory: involves general information about rules and things that we
have over learned. We can’t remember exactly how or when we learned this
information.
b) Episodic Memory: memory for specific events or episodes, these are usually
unique events rather than repeated ones.
Implicit or Incidental memory is demonstrated when recall occurs on a task that
does not requires intentional recall.
Explicit memory is information that you intentionally try to remember.
Inability to recall information in LTM
1) Pseudo Forgetting
2) It got lost along the way
3) Information is available but not accessible.
Why is information not accessible?
1) Context dependent forgetting or Encoding Specificity Hypothesis when the cues
at encoding and retrieval don’t match. We can you trouble recalling. We are using
an inappropriate search strategy.
2) State dependent forgetting: When one’s physical/mental state on mood is
different at encoding and retrieval, recall is less likely
Interference is defined as competition from other material.
a) Retroactive Interference: newer information interferes with the recall of
previously learned information
b) Proactive Interference: older information interferes with the recall of newly
acquired information.

Document Summary

Procedural memory system: a memory for how to do things, a memory for skills and actions. Example: riding a bicycle, how to tie your shoes, driving a car. Declarative memory system: memory for information and facts: semantic memory: involves general information about rules and things that we have over learned. We can"t remember exactly how or when we learned this information: episodic memory: memory for specific events or episodes, these are usually unique events rather than repeated ones. Implicit or incidental memory is demonstrated when recall occurs on a task that does not requires intentional recall. Explicit memory is information that you intentionally try to remember. Inability to recall information in ltm: pseudo forgetting, it got lost along the way, information is available but not accessible. Why is information not accessible: context dependent forgetting or encoding specificity hypothesis when the cues at encoding and retrieval don"t match.
