 Explicit, Implicit memory  Two kinds of Explicit memory  Semantic and Episodic memory  Physiology of memory  Rats experiment  Brain imaging  Forgetting

 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?)

 Physiological Evidence  Amnesiacs who cannot remember anything 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)

 Amnesiac ‘K.C.’  He cannot remember himself ever experiencing 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 memory  About the world, such as abstract knowledge, knowledge of principles, laws and facts. (K.C. has)  Episodic memory  Knowledge consisting of personal memories of events that have happened to the individual.

 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

 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-Memory’  Brain Injury  Fading Theory  Distortion Theory  Repression Theory  Interference Theory  Retrieval-Cue Failure
