Describe Short Term Memory
|
Attention is enough,
intent is not needed once stored in STM, control processed may applied to info such as rehearsal and chunking |
|
|
Describe Long Term Memory
|
stored indefinitely, perhaps permanently.
Different Memory storage altogether to STM |
|
|
Name 4 differences between Long Term and Short Term Memory
|
The form the info is stored
the way its recalled the reasons its forgotten The physical location of function in the brain |
|
|
Describe LTM Types through example
|
I know what a guitar is: Semantic
I remember buying my first guitar: Episodic I remember how to play: procedural |
|
|
What is working memory? Where is it stored? Give examples
|
Working Memory is stored in the Prefrontal cortex.
Visuospatial sketchpad: stores visual info Phonological loop: stores auditory info independent of visual memory Central executive: directs attention toward one stimulus or another. |
|
|
Describe the case of Patient H.M, what is he an example of and who reported it and when?
|
Reported by Scoville and Milner in 1957
Experimental brain surgery for epilepsy removed his hippocampus. Suffered mild retrograde amnesia, 1-3 years. Debilitating anterograde amnesia, could not remember events post surgery. Could define common words. Learn facts slowly. |
|
|
What memory is the Cerebral Cortex responsible for?
|
Long Term Memory
|
|
|
How is the Hippocampus involved in memory.
|
Critical in declarative explicit and spatial memory. London Taxi drivers, longer on the job, bigger the Hippocampus. Intergration and consolidation of seperate sensory info, transfers newly synthesized info into long terms structures.
|
|
|
How is the Amygdala involved in memory.
|
Memory consolidation for emotional experiences. Flashbulb memories part of process, improves recall but disrupts Hippocampus through cortisol hormone.
|
|
|
How is the Basal Ganglia involved in memory.
|
Procedural Knowledge, lets you play that guitar.
|
|
|
Describe the Stages of Memory through Example
|
Stages of Memory
You are standing on top of Kilimanjaro above the clouds. Visual Sensory info goes to the eye, then thalamus, than occipital lobe, neural activity would amount sensory register Close your eyes and recall the visual image from the sensory register Image kept in memory in STM 5 years later still recall the scene stored and integrated in Hippocampus Hippocampus transferred info from STM to LTM Stored permanently in the occipital lobe Recall the image, frontal lobe plays key role |
|
|
How does alcohol affect your memory?
What are possible long term problems? |
Alcohol disrupts serotonin activity.
Korsakoff's syndrome, devastating from of anterograde amnesia, often accompanied by retrograde amnesia. |
|
|
What is Hebbian theory? And how did Eric Kandel provide evidence.
|
Physical change occurs in nervous system when we learn. Donald Hebb's theory(1949) The more a synapse is used, the more the neural pathway is facilitated. Eric Kandel . Classically conditioned to withdraw gills and water siphons when siphons were touched. After habitation, they stopped withdrawing, the amount of neurotransmitter present at each synapse declined, while after classical condition, it increased.
For simple learning, it is remembered at the synapse. |
