Q

S&C aims

A

Testing a number of variables

  1. would similarity of the unexpected event to the attended event have an effect on inattentional blindness?
  2. would a particularly unusual event be more likely to be detected?
  3. would giving participants a more difficult task to do increase the rate of inattentional blindness?
  4. would use of a more realistic video (opaque) give different findings from those obtained via Neisser’s transparent video?

Q

S&C procedure

A

Participants tested individually
Told to count number of passes in clip
Couldn’t write down during cheek, had to count in head, then write on paper at the end
3 questions participants asked at the end
1. “While you were doing the counting, did you notice anything unusual in the video?”
2. “Did you notice anything other than the 6 players?”
3. “Did you see a gorilla/woman walking across the screen?”
If they answered yes to any, asked for more details and not asked later questions
Debrief and offered viewing of video after

Q

Grant type of data collected

A

Quantitative

27
Q

Grant conclusions

A

Context dependent memory aids both recall and recognition tests (contradicting previous research)

Grant suggests it is because P were learning meaningful prose rather than list of words

28
Q

Grant internal reliability

A

High

Lab- standardised controls (2 min break, order Qs)

29
Q

Grant external reliability

A

Low

39 across 4 conditions

30
Q

Internal validity

A

Construct

High- controls rid of EVs

31
Q

Grant external validity

A

Ecological
More true to life than others like word lists
Similar to real life college testing

32
Q

Grant ethnocentrism

A

Memory should be relatively universal

33
Q

Contemporary studies

A

Grant et al and Simons and Chabris

34
Q

Classic studies

A

Moray

Loftus and Palmer

35
Q

Moray 1: aim

A

Test Cherry’s findings more rigorously

36
Q

Moray apparatus used

A

Brenell stereo graphic tape recorder

Headphones

37
Q

Moray pretest

A

Participants given 4 passages of prose to shadow for practice
69 DB
150 wpm

38
Q

Moray key terms

A

Dichotic listening- different outputs played to each ear
Shadowing- day out loud what they hear
Affective- meaningful instruction like their name
Non affective- non meaningful instruction (without name)

39
Q

Grant ind/sit

A

Sit

Focused not on individual ability but how context affects recall/recognition

40
Q

Grant psy as science

A

Scientific
Objective- quantitative data eg. 12.7&14.3 recognition task
Falsifiable- can repeat to prove wrong easily and quantifiable results to compare with and measure
Replicable- lab experiment had controls like 2 min break, headphones etc

41
Q

Grant free-will/determinism

A

Free-will
Shows how we can use our free will in order to increase effectiveness of memory and recall (matching context)
Deter
Memory may not be based on effort to remember or attention but determined by context cues

42
Q

L&P aim

A

Investigate effects of language (in leading questions) on memory

43
Q

L&P experiment 1 sample

A

45 American students (male and female) Washington state uni

5 conditions- 9 each condition

44
Q

L&P experiment 1 procedure

A
P watched 7 road safety clips 
Some videos had staged car crash 
Between 5-30 sec video 
P then filled out questionnaire
Critical Q: about how fast were cars going when \_\_\_\_ eachother ? (Smashed, collided, hit, bumped, contacted)
45
Q

L&P experiment 1 findings

A
Smashed- 40.8 MPH 
Collided- 39.3 MPH 
Bumped- 38.1 MPH 
Hit- 34 MPH
Contacted- 31.8 MPH
46
Q

L&P Conclusion/explanations finding experiment 1

A

Leading questions affect accuracy of memory
Response bias- verb biased them to make a higher estimate
Verb affected memory- caused them to genuinely remember the crash as more serious

47
Q

L&P experiment 2 sample

A

150 students Washington Uni

3 conditions- 50 each

48
Q

L&P experiment 2 procedure

A

A clip of car crash
‘Hit’ or ‘smashed’ in critical question
Another group did not have critical Q
A week later asked if saw glass

49
Q

Experiment 2 L&P aim

A

Aimed to test which explanation was correct for experiment 1
Response bias or verb affected memory

50
Q

Experiment 2 L&P results

A
Speed estimate 
Smashed- 10.46
Hit- 8 
Glass reported 
Smashed- 16 
Hit- 7 
Control- 6
51
Q

2 experiment L&P conclusion

A

More likely to report broken glass with verb smashed
2 things merge to create memory:
1. Original perception
2. Information gained after

52
Q

Moray 1: sample

A

Students Oxford

53
Q

Moray 1: method

A

Dichotic listening task
- shadow prose from one ear ‘attended message’ other is ‘rejected message’
- simple word list repeated 35X
Chose from list of words whichever words they recognised

54
Q

Moray 1: results

A

Words recognised
Shadowed- 5
Rejected- 2
Neither message (but similar to attended)- 3

55
Q

Moray 1: conclusion

A

Much more able to recognise shadowed and almost none rejected/similar words could break inattentional barrier

56
Q

Moray 2: aim

A

Investigate if affective cues break IAB

57
Q

Moray 2: sample

A

12 students Oxford

58
Q

Moray 2: method

A

10 dichotic listening tasks
Used instructions ‘alright you may stop now’
Some had affective cues
‘John smith, you may stop now’
Counted as heard if instruction followed/ actually heard

59
Q

Moray 2: results

A

Affective- 20/39

Non- 4/36

60
Q

Moray 2: conclusion

A

Affective cues more likely to be heard

61
Q

Moray 3: aim

A

If being instructed to listen out for info breaks inattentional barrier

62
Q

Moray 3: method

A

Some participants told to look out for digits in dichotic listening task
- number towards end of rejected message

63
Q

Moray 3: results

A

No significant diff

64
Q

Moray 3: conclusion

A

Neutral info like digits cannot be made important enough to break barrier
