Fear conditioning |
A type of classical conditioning where a previously neutral stimulus is repeatedly paired with shock or some other unpleasant experience, causing the subject to act fearful in response to the stimulus. involves the amygdala |
|
|
Thorndike's operant task |
cat in a box needs to perform tasks to get out and get a reward latency decreases showing the cat has learned the task (time required to escape on Y axis) |
|
|
Skinner box |
Can be used for both classical and operant conditioning involves lots of experimental set ups--lights etc.. |
|
|
Morris water maze |
tests spatial memory learning can be visualized by plotting escape time across training days Rat must develop a learningset–Understandingof how a problem can be solved through the use of rules that can apply in avariety of situations |
|
|
Gollin figure task |
•Present subject with progressively clearer images until they canidentify the object (priming implicit memory) |
|
|
Explicit memory (declarative) |
–Consciouslearning •Encoded in a “top-down” manner •The cortex creates a mental representation of the goal active role in encoding |
|
|
Implicit memor (procedural) |
Unconscious learning •Encoded the way information is perceived “Bottom-up” •Passive role in encoding–Noconcrete recall of encoding processed by different brain areas than explicit memory –Lesscortical involvement in implicit than explicit memory |
|
|
Short term vs. Long term memories |
–Shortterm => frontal lobes –Longterm => temporal lobes needed for long term storage of verbal memories |
|
|
H.M. the man who couldn't remember (memory circuits) |
he underwent the experimental surgery that would destroy his ability to form long-term memories. Surgery to remove source of seizures •Permanent anterograde amnesia •Normal short term memory functional implicit memory |
|
|
Korsakoff's disease |
•Fail to recall previous experience •No familiarity with re-presented items caused by lack of thiamine--B1 which is caused by alcohol addiction, malnutrition etc. |
|
|
Other approach => Correlation |
•Chickadees gather and hide seeds (seedcaching) •Hippocampus is proportionally larger in chickadees |
|
|
Implicit memory circuits |
–Basalganglia gets input from entire cortex–Inputfrom substantia nigra •Parkinson’spatients exhibit memory deficits (loss of DA input to BG) –Basalganglia projects to ventral thalamus–Informationthen projected onward to premotor cortex |
|
|
_________ important for coding emotional memories |
Amygdala |
|
|
Amygdala lesions eliminate ____________ |
fear conditioning |
|
|
Patientswith impairments to implicit and explicit memory, but with functional amygdalas canexhibits behavior suggesting that? |
emotional memories are intact |
