Explicit, Implicit mem-ory(1/2)

Explicit(Declarative) memory Memories relating to people’s name and

addresses, their telephone numbers, and the name of their dogs (remembering?)

Implicit(non declarative) memory Memories relating to how to walk, how

to keep upright on a bicycle, how to hit home run, or how to do a triple lutz in ice skating (knowing?)

Explicit, Implicit mem-ory(2/2)

Physiological Evidence Amnesiacs who cannot remember any-

thing even his name and age. But, he can ride a motor skills

Above things are related to explicit memory, but non declarative things are remained(implicit memory)

Two Kinds of Explicit memory

Amnesiac ‘K.C.’ He cannot remember himself ever expe-

riencing or doing anything. He does not remember a single occasion.

He knows that his family owns a summer cottage, where it located, even he can point out the location on a map.

Semantic and Episodic memory

Semantic memory About the world, such as abstract

knowledge, knowledge of principles, laws and facts. (K.C. has)

Episodic memory Knowledge consisting of personal memo-

ries of events that have happened to the individual.

Physiology of Memory

Lashley’s Rats Lobbed off tiny chunks of brain He expected that the memory of maze

route is located in the specific part. False.

-> Memories are scattered throughout the brain rather than located in just one place.

Globalist’s view

Physiology of Memory

Brain imaging EEG(electroencephalogram) PET(Positron emission tomography) f-MRI(functional magnetic resonance

imaging)

Words or tones are stronger and more localized in the left temporal lobe Localist’s view

All of you saw this in ‘Human-Mem-ory’ Brain Injury Fading Theory Distortion Theory Repression Theory Interference Theory Retrieval-Cue Failure
