Transcript of Theories of forgetting
According to Munn (1967) “Forgetting is the loss, temporary orPermanent, of the ability to recall or recognize something learnt Earlier.”

PSYCHOLOGICAL FORGETTING
Theories of ForgettingTheories of forgetting can be difficult to test as
we may in fact not forget, but have trouble retrieving information from storage.
Therefore it is possible that these theories can explain why we are unable to retrieve a memory or why it is distorted.
Theories of ForgettingTwo factors involved in forgetting:
Accessibility: The information available can be accessed at a specific time/place.
Availability: The information is represented in the memory.
Theories of ForgettingFreud: Repression, conscious process of
burying memories to protect ego.
The emotions associated with the repressed memory may be recovered, or express themselves through:
Dream Analysis.Hypnosis.Free Association.
Theories of ForgettingTRACE DECAY THEORY
Natural forgetting which takes place due to the decay of memory traces in the brain and due to time.
Criticism – does not explain why we dont forget how to ride a bicycle.
Forgetting in STM.Trace Decay: Unless
information is refreshed or rehearsed will spontaneously fade or decay over time.
Displacement: Only a fixed number of slots in memory capacity. New information will displace old when capacity is reached.
Encoding failure: Because of displacement, this information never reaches the LTM.
WHY FORGETTING TAKES PLACE
Forgetting in LTM. Interference: More information
will be stored and become confused together.
Retrieval Failure: Information may be available but temporarily inaccessible
Motivated forgetting: we may actively work to forget memories. Two basic forms are
suppression- a conscious form of forgetting.
Repression- and unconscious form of forgetting .
