Q

Summarise briefly what Godden and Baddeley’s study was about (5) and what happened (2)

BACKGROUND

A
  • Participants were required to recall information
  • Divers listened to 40 unrelated words on the beach or under 10 ft of water
  • They were tested to see how many words they remembered
  • Matching conditions - remembered far more words
  • Mismatching condition - less words remembered

Q

What does Godden and Baddeley’s research suggest?

BACKGROUND

A

Suggests that characteristics of the environment are encoded as part of the memory trace and can be used to enhance retrieval of the other information in the trace.

Q

What does context-dependent memory mean

THEORIES

A

Context-dependent memory refers to improved recall of specific episodes or information when the context present at encoding and retrieval are the same.

Q

What was the aim of Grant et al’s study

AIM

A

Grant et al aimed to show that environmental context can have a more positive effect on performance in a meaninful memory test when the test takes place in the same environment in which the to-be-remembered material was originally studied (matching condition) than when the test occurs in a different environment (matching condition)

Q

How were participants ordered into conditions? (3)

PROCEDURE

A
  • Each experimenter ran one participant for each of the 4 conditions
  • One additional participant for one of the conditions - assigned by the instructor
  • Experimenters randomly assigned their participants to their 5 conditions

16
Q

What did the experimenter provide for the participants?

MATERIALS AND APPARATUS

A

Cassette players and headphones

17
Q

How many cassette players were there?

MATERIALS AND APPARATUS

A
  • 8

- Exact copies made from a master tape of background noise recorded during lunchtime in a uni cafe

18
Q

What did the background noise contain? (3)

MATERIALS AND APPARATUS

A
  • Consisted of occasional distinct words/phrases embedded within a general conversational hum
  • Intermixed with the sounds produced by movement of chairs and dishes
  • Moderate loud level
19
Q

What was the selected study material? (2)

MATERIALS AND APPARATUS

A
  • A two page, three-columned article of psychoimmunology

- Hales, 1984

20
Q

How many marks were the multiple-choice questions out of?

MATERIALS AND APPARATUS

A
  • 16 marks

- 16 multiple-choice questions

21
Q

How many marks were the short answer questions out of?

MATERIALS AND APPARATUS

A
  • 10 marks

- 10 short answer questions

22
Q

Why was the short-answer test always administered first?

MATERIALS AND APPARATUS

A

Ensure that recall of information from the article was being tested and not recalled from the Multiple choice questions

23
Q

What was read out aloud? (3)

PROCEDURE

A
  • Standardised instructions
  • They described the experiment as a class project
  • They said participation was voluntary
24
Q

What were participants asked to do with the article? (2)

PROCEDURE

A
  • Asked to read the given article once, as if it were for a class assignment
  • Allowed to highlight and underline as they read
25
Q

Were participants informed about what the comprehension would be used for? (2)

PROCEDURE

A
  • Yes

- Participants were told they would be tested with both a multiple choice test and the short answer test

26
Q

Why did all participants wear the headphones? (3)

PROCEDURE

A
  • Standardisation
  • Controlled methodology
  • To make sure the headphones didn’t affect the results
27
Q

What were participants in the silent condition told about the head phones vs the noisy condition (2)

PROCEDURE

A
  • SILENT - told they would not hear anything over the headphones
  • NOISY - told they would hear moderately loud background noise but that they should ignore it
28
Q

How long was the break the participants were given? (3) When was it? why was it used?

PROCEDURE

A
  • 2 minute break
  • between the end of the study phase and the beginning of the test phase
  • incorporated to minimise recall from short-term memory
29
Q

In what order were the tests given? + why? (4)

PROCEDURE

A
  • Short answer test first
  • Multiple choice questions last
  • prevents recall from MCQ
  • ensured information from the comprehension was being tested
30
Q

What happened at the end of the testing phase?

PROCEDURE

A

Participants were debriefed

31
Q

How long did the procedure last?

PROCEDURE

A
  • 30 mins
32
Q

Give two results from the short answer test

A
  • matching condition (SS) = 6.7/10 (MEAN)

- mismatching condition (SN) = 5.4/10

33
Q

Give two results from the multiple choice questions

A
  • Matching condition (NN) = 14.3/16 (MEAN)

- Mismatching condition (NS) = 12.7/16 (MEAN)

34
Q

What was reading time in the analysis of test performance? (2)

RESULTS

A
  • a co-variable

- P’s in all groups spent roughly the same time studying the material

35
Q

What is a co-variable?

RESULTS

A

Variables investigated in a correlation

36
Q

Did noise have an effect on performance?

RESULTS

A

There was no overall effect of noise on performance

37
Q

Are there context-dependency effects for new material? (2)

CONCLUSIONS

A
  • Yes
  • There are context-dependency effects for newly learned meaningful material regardless of whether a short-answer test or a multiple-choice test is used to assess learning
38
Q

Does studying in the same environment have an effect? (2)

CONCLUSIONS

A
  • Yes

- Studying and testing in the same environment leads to enhanced performance

39
Q

How can students perform better in exams? (2)

CONCLUSIONS

A
  • Students can perform better in exams if they study for them with a minimum of background noise
  • Because, although there was no overall effect of noise on performance, the fact that there was no evidence for context-dependency suggests they are better off studying without background noise as it will not be present during the actual testing
