PSY 100 Lecture Notes - Lecture 24: Space Shuttle Challenger Disaster, Implicit Memory, Brainstem
Document Summary
Memory models: encoding > storage > retrieval. Storage: the brain has a vast storage capacity, storage is not like a library, many parts of the brain interact as we encode, store, and retrieve information. Cannot move memories into long term storage. Tell me what this is and what it demonstrates. Can learn implicit tasks, even though they felt new to him: amygdala (the brain"s almond) Amygdala: almond-shaped organ in limbic system, communicates with neocortex, thalamus, brain stem, emotional computer (ledoux, 1992) Plays role in releasing stress related hormones, during highly emotional experiences: animal lesions in amygdala. Block learning of avoidance response in fear conditioning. Couldn"t remember that they should be afraid: human lesions in amygdala (young, 1997) What changes is their ability to process emotional information auditory. No memory for interpreting of auditory stimuli. Can recall what it feels like to feel a certain emotion, but can no longer interpret tone of voice appropriately.
