Q

Why is it easier to study human memory than animal memory?

A

Humans can make explicit responses to memory tasks, but memory in animals must be inferred from their behaviour

Q

How do studies of learning and studies of memory differ?

A

Q

T or F: The delayed matching to sample procedure can be used to determine how animals remember different types of stimuli.

25
In DMTS procedures, is longer exposure to the sample typically associated with increased or decreased performance?
Increased performance
26
In DMTS procedures, is a longer retention interval typically associated with increased or decreased performance?
Decreased performance
27
T or F: Memory fades as a function of time.
False
28
In DMTS, did longer retention intervals during training result in increased or decreased performance during testing?
Better
29
In terms of the retention interval, when was the best performance on DMTS testing observed?
When the testing interval matched the training interval
30
In DMTS, does a signal prior to making the choice, indicating that a large reward for the correct response, improve or impair performance?
Improves performance
31
During the retention interval of DMTS, does switching the reward signal from one indicating a large reward to one indicating a small reward improve or impair memory?
Impairs memory
32
During the retention interval of DMTS, does switching the reward signal from one indicating a small reward to one indicating a large reward improve or impair memory?
Improves memory
33
T or F: Memory is an active process that matches the demands of the environment
True
34
DMTS is thought to train participants to use what rule/concept?
A general "same-as" rule/concept
35
How does the general "same-as" rule assume participants make a choice in DMTS?
By choosing the choice stimulus that is the same as the sample stimulus
36
What is an alternative explanation to the general "same-as" rule in DMTS?
S-R learning is occurring (participants are learning multiple rules related to the stimuli)
37
In a DMTS task, is general "same-as" learning or S-R learning more common with a small stimulus set?
S-R learning
38
In a DMTS task, is general "same-as" learning or S-R learning more common with a large stimulus set?
General "same-as" learning
39
What are trials-unique DMTS procedures?
When each trial uses a different sample
40
Does accurate performance in trials-unique DMTS procedures require general "same-as" learning or S-R learning?
General "same-as" learning
41
What does the Morris water maze involve?
Involves placing rodents in opaque water and measuring how they learn to find the platform
42
In the Morris water maze, how do rodents learn to locate the platform?
They use spatial cues in the room
43
What are the two main measurements taken during a Morris water maze?
- Escape latency - Distance moved
44
What does escape latency measure in a Morris water maze procedure?
The amount of time rodents take to find the platform
45
During the Morris water maze, when is the biggest improvement in performance typically observed?
The first two days
46
Do Morris water mazes have high or low ecological validity?
Low
47
Which maze takes advantage of an animal's evolved strategies for finding food in their environment?
The radial arm maze
48
What does a radial arm maze typically look like?
There are a certain number of arms originating from the centre, each with a food pellet placed on the end of each arm
49
In a radial arm maze, once the food at the end of an arm is consumed, is it replaced?
No
50
How do rodents typically respond in a radial arm maze?
They attempt to eat all the food in the most efficient way possible
51
In a radial arm maze, with little to no training, do rodents typically re-enter the arms they have previously chosen?
No
52
In radial arm mazes, how do rats locate maze arms and remember which ones they have already visited?
Using distinctive features in the environment as landmarks
53
In radial arm maze, is spatial location determined by distal cues in the room or local cues in the maze?
Distal cues in the room
54
If landmarks in the experimental room are moved, how will the rat treat the arms in a radial arm maze?
As if it were a new location
55
Rats can perform the radial arm task with accurately with up to how many arms?
16-24
56
What type of memory is being assessed with a radial arm maze?
Working memory
57
How can a radial arm maze task be modified to assess the duration of spatial memory?
By allowing rats to collect food from only half of the arms, then removing them for a retention interval before returning them to retrieve the remaining pellets.
58
When using a radial arm maze to test the retention of spatial memory, did rats perform better when the retention interval was long or short?
Short
