Q

procedure in Moray’s experiment 1

A

-participants shadowed a piece of prose they could hear in 1 ear (attended message)
-in other ear a list of words was repeated 35 times (rejected message)
-at the end participants completed a recognition task where they had to indicate what they recognised from a list of 21 words
-7 words were in attended passage, 7 were in rejected and 7 were in neither passage

Q

procedure in Moray’s experiment 2

A

participants listened to 2 different passages at the same time
contained an instruction at the start and within them
both passages read in a steady monotone in a male voice

some instructions said name, you may stop now and some did not say name

Q

what was the dependent variable in Moray’s experiment 3

A

how many digits our participants can recall from the rejected message

20
Q

procedure of Moray’s experiment 3

A

1) 1 group was told they would be asked questions about the shadowed message at the end of each message
2) the other group were specifically told to remember as many of the digits as possible

21
Q

results from Moray’s experiment 3

A

showed no difference in the mean scores of digits recalled correctly between the 2 set conditions - numbers cannot break through the block on the rejected message

22
Q

background to Loftus and Palmer’s study

A

Loftus was interested in the fragility of memory- how easily we can forget information

23
Q

what is schema theory

A

the ability to retain information and to demonstrate this retention of information through behaviour

24
Q

what is reconstructive memory

A

the way in which our biases and prejudices can unconsciously lead us to have memories of events that are distortions of what actually happened

25
Q

what are leading questions

A

a question which, by its form or content, suggests what answer is desired

26
Q

aim of Loftus and Palmer’s study

A

to investigate the effect of language on memory

27
Q

sample for Loftus and Palmer’s experiment 1

A

45 split into 5 groups of 9
students from Washington, USA

28
Q

what was the dependent variable in Loftus and Palmer’s experiment 1

A

estimated speed of car in video

29
Q

what were the 5 verbs used for IV in Loftus and Palmer’s experiment 1

A

-smashed
-bumped
-collided
-hit
-contacted

30
Q

procedure to Loftus and Palmer’s experiment 1

A

1) students were shown 7 clips from Evergreen Safety council of the Seattle Police Department. The staged clips lasted between 5 and 30 seconds. 4/7 clips were staged crashes where the speed at which they crashed was known
2) after each clip they were given a questionnaire
‘About how fast were the cars going when they ——- each other’

31
Q

results

A

smashed - estimate speed of 40.8
contacted - 31.8

32
Q

sample of Loftus and Palmer’s experiment 2

A

Washington, USA
150 split into 3 groups of 50
students

33
Q

procedure of Loftus and Palmer’s experiment 2

A

stage 1- participants watched a clip of a car crash
answered questionnaire (exp 1) verbs= hit/crashed

stage 2- a week later participants returned to answer more questions including ‘did you see any broken glass’

34
Q

results for Loftus and Palmer’s experiment 2

A

smashed - 16 remember seeing broken glass
hit- 7 remember seeing broken glass

35
Q

background to Grant Et Al’s study

A

context dependent memory is the idea that we are able to recall information best if we return to the same context we learnt the information, this was first investigated by Godden and Baddeley on divers

36
Q

aim to Grant’s study

A

whether the kind of context-dependency effect that has often been reported for recall (but not recognition) of unrelated lists of words would also be seen in relation to the type of meaningful prose that is presented in many academic courses

37
Q

sample and location of Grant’s study

A

17 females 23 males 17-56 years
data only analysed for 39

38
Q

what sampling method was used in Grant’s study

A

snowball, eight student researchers recruited 5 acquaintances to take part

39
Q

procedure to Grant’s study

A

participants read a short article on psychoimmunology (interesting)
either read article in silence or with cafeteria noise (both wore headphones)
they took a recall test and then multiple choice recognition test either with noise or silence

40
Q

results to Grant’s study

A

for recall tests taken in silence and article read in silence score was 6.7/10 compared to 4.6 for test taken with noise and article read in silence

41
Q

background to Simon and Chabris’ study

A

interested in inattentional blindness- when people fail to see something because they are paying attention to something else

investigated by Neisser as most people failed to see woman with umbrella whilst focusing on a basketball game in a video

42
Q

aim of Simon and Chabris’ study

A

wanted to investigate whether the results from Neisser’s research were affected by the way he had made his video (transparent effect) and whether the results would differ for an opaque video

43
Q

sample of Simon and Chabris’ study

A

228 participants
students at Harvard University
results were only based on data from 192 participants

44
Q

procedure of Simon and Chabris’ study

A

each participant watched a short video, and was then asked questions about what they had seen
the video was either:
-opaque or transparent
-a woman with umbrella or woman in gorilla costume
-counting basketball passes of black/white team
-easy task or hard task count aerial and bounce passes

45
Q

results from Simon and Chabris’ study

A

easy task white team transparent umbrella- 58 noticed
easy task white team transparent gorilla - 8 noticed
