Learning and Remembering (Part2)

Explore the intricate workings of memory processes involving explicit and implicit recall. Discover the nuances of semantic and episodic memory, brain imaging techniques, amnesiac cases, and physiological evidence, shedding light on forgetting mechanisms. Delve into concepts such as Lashley’s rats experiment, brain injury effects, and various theories of memory retrieval.

  2. Question

  3. Contents • Explicit, Implicit memory • Two kinds of Explicit memory • Semantic and Episodic memory • Physiology of memory • Rats experiment • Brain imaging • Forgetting

  4. Explicit, Implicit memory(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?)

  5. Explicit, Implicit memory(2/2) • 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)

  6. Two Kinds of Explicit 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.

  7. 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 memories of events that have happened to the individual.

  8. 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

  9. 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

  10. Forgetting • All of you saw this in ‘Human-Memory’ • Brain Injury • Fading Theory • Distortion Theory • Repression Theory • Interference Theory • Retrieval-Cue Failure

  11. Thank you
