1974
4
Q
What is a schema?

5
Q
What is the background of Loftus and Palmer’s study?
A
- Memory involves interpreting what is seen or heard, recording it, then reconstructing it
- Recall can be distorted or biased
- Investigated how memory can be distorted
6
Q
What was the aim of Loftus and Palmer’s experiment 1?

1998
27
What is a cue?
Extra information/ triggers
28

Accessing memories with few prompts
29
What is recognition?
Identifying items you have seen before
30
What is meaningful information?
Information that is understandable and relatable
31
What is cue dependency?
- Other information is stored alongside to-be-remembered information
- Extra information aids recall
32
What is context dependent memory?
Improved recall of specific information when context present at encoding and retrieval and the same
33
What is the background of Grant’s study?
- Research shows context dependence memory may be important
- Grant wanted to see if environmental context dependency effects would be found in school
34
What was the aim of Grant’s study?
To test the effect of noise as a source of context on the studying and retrieval of information in an academic context
35
Who were the participants in Grant’s study?
- 39 American participants
- From Iowa state university
- 17-56 years old
- 17 female, 23 male
- 8 members of a psychology class were experimenters, each gathered 5 friends
36
What were the 4 conditions used in Grant’s experiment?
- Silent silence
- Noisy noisy
- Silent noisy
- Noisy silent
37
TRUE OR FALSE:
Only members of the noisy condition wore headphones when reading the article
FALSE:
All participants wore headphones for standardisation
38
How long was the break between the end of the study phase and beginning of the test phase?

Once
40

48
When was Moray’s study?
1959
49
What is the background of Moray’s study?
- Broadbent said the world is composed of more sensations than humans can handle
- Cherry- shadowing dichotic messages found that if you shadow one ear you miss the other message
50
What is shadowing?
The participant can hear two different messages and is asked to retreat one as they hear it and reject the other
51
What is the aim of Moray’s study?
To test Cherry’s dichotic listening findings in relation to the amount of information recognised in the rejected message, the effect on hearing their name in the unattended message, and the effect of instruction to find a specific target in the rejected message
52
Who was the sample used in Moray’s study?
- Undergraduate students or research workers of both genders
- Number in experiment 1 is unknown
- 12 took part in experiment 2
- Two groups of 14 in experiment 3
53
Describe the procedure of experiment 1 of Moray:
- Short list of words repeated 35 times in unattended ear, shadowed prose message in attended ear
- Participant was asked to recall everything they could from the unattended message
- Recognition test made up of words from shadowed message, rejected message, and control words not present in either
54
What are the results of experiment 1 of Moray’s study?
- No evidence that words from rejected message were recognised
- 4.9/7 shadowed words recognised
- 1.9/7 rejected words recognised
- 2.6/7 control words recognised
55
Describe the procedure of experiment 2 of Moray’s study:
- Participants shadowed 10 short passages of light fiction, each with different instructions
- 4 conditions with no instructions
- 3/6 conditions with instructions used the participants name
56
What were the results of experiment 2 of Moray’s study?
- Most participants ignored instructions in shadowed passages
- Significant difference between hearing instructions with name vs no name (3.05)
57
What was the procedure of experiment 3 of Moray’s study?
- Messages are made with digits interspersed and words towards the end
- One group was told they’d be asked about the passage the other group was told to remember as many numbers as they could
58
What were the results of Moray’s experiment 3?
- No significant difference between the number of digits listed when told to listen for them vs when not told to listen to them
59
What conclusions can be drawn from Moray’s study?
- When someone listens to one message and rejects the other, almost none of the rejected message is heard (1)
- A short list of words as the rejected message shows little trace of being remembered (1)
- Important messages like a person’s name often can penetrate the attentional barrier (2)
- It is difficult to make material important enough to break the attentional barrier (3)
