Document Summary
Retrieval: transferring information from ltm to working memory: crain and lockhart (1972) Depth of processing: shallow processing, little attention to meaning, focus on physical features, poor memory, deep processing, close attention to meaning, better memory. Levels of processing theory is circular, and the theory has fallen out of favor: other factors that aid encoding. Retrieval: process of transferring information from ltm back into working memory (consciousness: most of our failures of memory are failures to retrieve. Long-term potentiation (ltp): enhanced firing of neurons after repeated stimulation. Ltm happens in the amygdala and medial temporal lobe: the fragility of new memories. Graded amnesia: memory for recent events is more fragile than for remote events. As time passes after an event, a process called consolidation stabilizes memory for the event, so it is less likely to be affected by trauma: synaptic consolidation occurs at synapses, happens rapidly.
