Weekly Quizzes Flashcards
What was described as Dr. McGaugh’s first “big idea”?
A) The memories of rats and mice consolidate like those of subjects in Mueller and Pilecker’s experiments.
B) The stress hormones can affect memory.
C) That the amygdala is involved with declarative memory.
D) Two of the Above
E) None of the above
E) None of the above
The answer is that memories are malleable for some time after they are initially acquired not so that could be lost, but so that they could be enhanced when appropriate.
The experimental approach McGaugh invented based on the realization that memories are malleable or change able for a period of time after they are initially acquired was to?
A) Administer drugs after rather than before learning
B) Use different ones of drugs in order to establish the “inverted u” dose response curve.
C) Administer ECS after learning to impair consolidation.
D) None of the above
A) A) Administer drugs after rather than before learning
This was based on Mcgaugh’s “first big idea”.
This helps address the learning performance dilemma.
Which of the following is NOT among the evidence supporting the McGaugh model of memory modulation for emotional events in human subjects?
A) Studies using PET to measure norepinephrine release in the amygdala and relate it to memory for emotional events.
B) Studies of people receiving injections of stress hormone at physiological doses.
C) Studies of healthy people given beta-aderergic blocking drugs.
D) Studies of norepinephrine activation in response to emotional learning.
E) None of hte above (all of the above are among the evidence).
A) Studies using PET to measure norepinephrine release in the amygdala and relate it to memory for emotional events.
This type of study was not used to support Mcgaugh’s model of memory modulation for emotional events in human subjects. Instead it was done by measuring saliva.
4) Which of the following should we expect to reduce the effect of an optimal memory enhancing dose of epinephrine on memory?

B) Elimination of glycogen stores in the liver
C) Cutting the vagus nerve
D) Two of the above
E) All of the above

Patient MS showed intact explicit memory but had a defect in perceptual priming and implicit memory process.
This patient lost half his visual cortex. Impaired priming
6) I ask you to name something that relates to “forest” and you respond
“animals.” Later you are more likely to say “animals” when again prompted with the word “forest.” Brain imaging results suggest that?
A) This form of memory results from enhanced activity of the amygdala
B) This form of memory results from impaired activity in the hippocampus
and surrounding archicortex
C) This form of memory results from more efficient activity in the sensory
cortex of the brain
D) None of the above
D) None of the above
This form of memory results from less efficient activity in the sensory cortex of the brain.

A) tests showing that priming and recognition memory are differently
affected by electro-convulsive shock (ECS)
B) human imaging studies using the “subtraction” approach
C) studies of patients with selective amygdala damage
D) studies manipulating “massed versus distributed” processing in
subjects learning words
E) three of the above
B) human imaging studies using the “subtraction” approach
Brain Imaging Experiment:
1) Scan people while doing word stem completion to words they had seen before.
2) Scan people again doing word stem completion to words they had not seen before.
3) Subtract 2 from 1
A rat is given one week of daily trials in a T maze (moderate training). Up to to this point.
A) His hippocampus has been learning spatial arrangement of the maze and room.
B) His caudate has not been learning S-R relationships that lead to the food.
C) Two of the above
D) None of the above.
A) His hippocampus has been learning spatial arrangement of the maze and room.
This is true, during this phase the rat’s hippocampus is actively figuring out the spatial arrangement of the room.
A rat is given two weeks of daily trials in a T maze to turn left to find food. Before a probe trial its caudate is inactivated. At the choice point during a probe trial the rat most likely will?
A) Turn left
B) Turn right
C) Both equally likely to turn left or right.
B) Turn right
Hull Rats (S-R rats)
This is because the rat has been trained to turn left to find food. During a probe trial the caudate is inactivated so it won’t rely on its S-R behavior and instead will turn the opposing direction??? (ASK ABOUT THIS ONE)
A rat in placed in one arm of a maze in which it receives a very large amount of food. Next it is placed in another arm in which it receives no food. Inactivation of which structure with lidocaine before the learning trials would most likely disrupt learning of which place it prefers
A) The hippocampus
B) The caudate
C) The amygdala
D) None of the above
A) The amygdala
Because the rat was likely overwhelmed when it was given the conditions of either a surplus of food or too little food. Thus this is an emotionally loaded memory. Thus if the amygdala (emotion processing center of memory) was diruspted then the learning would also be disrupted.
The finding from their experiments that Mueller and Pilzecker were trying to account for that led them to create the concept that memories “consolidate” was
A) Time dependent retrograde interference.
B) Time dependent retrograde enhancement
C) Massed vs. Distributed Practice.
D) Two of the above
E) All of the above
A) Time dependent retrograde interference.
The learning of the 2nd list of syllables impaired memory for 1st set of syllables.
The experiment of Duncan 1949 is important in that it?
A) Provided first evidence of Ribot’s Law
B) Demonstrated for the first time that electroconvulsive shock could cause retrograde amnesia.
C) Provided the first demonstration of a controlled retrograde amnesia gradient in a single experimental study.
D) Was performed at Northwestern University
E) Two of the above
D) All of the above
C) Provided the first demonstration of a controlled retrograde amnesia gradient in a single experimental study.
The other options are untrue and it is not important that this experiment was conducted in Northwestern University.
A subject is given a PET scan once when they are learning a list of words, and again while resting. We subtract the activity in the second scan from the first scan. Where should we expect to see greater activity in the learning compared to rest condition?
A) Amgydala
B) Hippocampus
C) Archicortex around the hippocampus
D) Two of the above
E) None of the above
E) None of the above
In studies of declarative memory: hippocampus is not lighting up.
Method was too crude so they were not able to see the activation.
This is why the subtraction method failed and subsequent memory method worked.
Which of the following suggested that the amygdala was not involved with declarative memory formation?
A) Studies of patient IS
B) Studies of monkeys using the delayed non-match to sample paradigm with trial unique objects.
C) Studies of rats learning to find 8 pieces of food in a Radial Arms Maze.
D) Two of the above
E) All of the above
E) All of the above
A) Patient IS made it seem like amygdala didn’t have anything to do with memory.
B) Monkeys also seemed to have more of a focus on the caudate and hippocampus not amygdala
C) 8 pieces of food experiment was thought to be more S-R like
Triple Dissociation Experiment: Expect inactivation of amygdala and not the hippocampus or caudate.
Which brain imaging data are compared in the Subsequent Memory method?
A) Brain activity during encoding vs. retrieval of correctly remembered information.
B) Brain activity during retrieval of correctly remembered vs incorrectly remembered information
C) Brain activity at encoding of material that was subsequently remembered vs subsequently forgotten
D) None of the above
C) Brain activity at encoding of material that was subsequently remembered vs subsequently forgotten
1) Scan subjects while they learn a list of items to be remembered, record responses to each item.

C) Complete inability to perform any of the three tests because hippocampal damage impairs the ability to distinguish between odors.
D) Performance of tests of transitivity and symmetry are both impaired, but simple association ability is intact.
E) None of the above.
D) Performance of tests of transitivity and symmetry are both impaired, but simple association ability is intact.
