Answer 6

avoidance response learning - where CS predicts a shock, forgetting occurs 3 days later unless a reminder is given.
Reminders most effective when closest to test procedure.

Answer 7

reminders 72 hours prior to test were ineffective to elciting avoidance response

Answer 8

used a Krechevsky maze to test effect of reminders on performance

Question 9

Deweer and Sara (1984) tested rats ___ days after initial training, and found that performance was best using a reminder ____ seconds prior to the test.

Answer 9

Tested rats after 25 days
found that performance was best when reminder given 90 seconds prior to the test

Question 10

Studies into reminders by Deweer and Sara, and Gordon et al suggest what about memory?

C Memories can be retrieved given reminders
D Both A and C

Answer 10

D both A and C

Question 11

What are the 2 main theories of forgetting?

Answer 11

Trace decay theory
Interference theory

Question 12

What does trace decay theory suggest about memory formation and forgetting?

Answer 12

Learning and storage reflected by physical changes in the brain - connections made
In absence of rehearsal, connections decay/become weaker until trace disappears

Question 13

True or false, trace decay theory can account for reminders/ cue retrieval

Answer 13

False

Question 14

Trace decay theory is based on whos rule of learning?
A Skinner
B Pavlov
C Hebb
D Thorndike

Answer 14

C Hebb

Question 15

What are the 3 main premises of Interference theory? (McGeoch, 1932)

Answer 15

Human memory is associative so recall is guided by cues associated with memory formation
Due to many memories multiple items may become associated with the same cue
Memories can be interfered by other memories/associations formed before or after

Question 16

Proactive interference is when ____________________________________________________________

Answer 16

Proactive = when you are trying to ACTIVATE a newer memory and older memories interfere. The older memory proactively interferes and goes forward in time.

Question 17

Retroactive interference is when _____________________________________________

Answer 17

Retroactive = when you are trying to ACTIVATE older memory and a newer one interferes. The newer memory retroactively interferes and goes back in time

Question 18

What are the 3 main implications of interference theory?

Answer 18

memories can be ‘forgotten’ without being lost
Cues help trigger memory, so has an associative base
Forgetting mainly due to interference

Question 19

Marcel Proust’s anecdote regarding the smell of ________ and feeling of _________, explains the principles of association

Answer 19

Smell of varnish and feeling of sadness explains principles of association

Question 20

During learning, stimulus __ + stimulus __ leads to the thought of what stimulus _ brings about

(CS+US —> UR)

Answer 20

Stmulus A + Stmulus B leads to what Stimulus B brings about

Question 21

After learning, stimulus __ alone can lead to the thought of stimulus __, even when stimulus __ isn’t present

(CS —–> CR

Answer 21

Stimulus A leads to thought of stimulus B even when stimulus B not present

Question 22

What type of design did the Godden and Baddeley scuba diver study use? What were the results?

Answer 22

cross-over study using learning in one environment and recall in a different
where environments underwater and on land were uses

Land learning -> land recall best
Water learning -> water recall
Land learning-> water recall
Water learning-> land recall worst

Question 23

Godden and Baddeleys scuba diver study is an example of _________ _______ ________.

Answer 23

Context dependent memory

Question 24

Apart from dry vs wet (Godden and Baddeley) what are 2 other ways environmental context can be altered?

Answer 24

Odors - such as children’s toys, mothballs, baby powder, museum smell
Music

Question 25

Tulving and Thompsons (1973) Encoding specificity principle (ESP) says that_____________ in ______________ provides a ________ _________ that can be used as a _______ in ________

Answer 25

Encoding in context provides a memory trigger that can be used as a cue in retrieval

Question 26

Effective cues enable the ___________ __ _____that wouldn’t have been _____________ under ___-_____ ______ conditions

Answer 26

Effective cues enable the retrieval of items that wouldn’t have been retrieved under the non-cued recall conditions

Question 27

Parker al 2001 used the smells of __________ and ___________ to show the effectiveness of ___________ contexts used as ______ in retrieval

Answer 27

lemon and lavender smells to show effectiveness of smell contexts used as cues in retrieval

Question 28

Cassaday et al (2002) used a crossover design to test the affects of relaxed vs standard environments on memory/problem solving tasks

What were the 2 different environments – how many different cue-recall environments were used?

What 3 different tasks were used?

What were the findings?

Relaxed - relaxed
standard-relaxed
relaxed-standard
standard-standard
