Q

How would this first order test check for theory of mind?

A

If a child has theory of mind they would answer that Sally would look in her basket - those who lack theory of mind would say the box as they know that is where it is and they don’t understand that Sally has different perspectives and thoughts to them

Q

What is the aim of the Baron-Cohen study?

Q

What is the importance of the gender split in the experimental sample?

A

Initially it may seem bias but it reflects the the ratio of diagnoses of Autism due to males receiving more diagnosis’s than females

Q

What did the experimental group have to do before the study?

A

complete the Wechsler intelligence test and score above 85 in order to prove they had a average intelligence level and are able to complete the Sally Anne Task

Q

What was the sample in control group 2?

A

10 people with Tourette’s syndrome
- age-matched with experimental group
- gender ratio is also mirrored with the experimental group (8 males, 2 females)

Q

What is a strength of age-matching the participants?

A

As theory of mind suggests that it develops over time comparing different ages there will be differences in ability - age-matching removes this

21
Q

What is a strength of the sample in the experimental group?

A

As there are both males and females and the sample consists of those with both high functioning autism and Asperger’s it makes results more generalisable

22
Q

What is a weakness of the experimental sample?

A

It is ethnocentric as it only samples British people and different cultures may have different explanations for Autism making results less generalisable

23
Q

What was the sampling technique in this study?

A

Self-selected (volunteer)

24
Q

How was a self-selected sample used in this study?

A
  • placing an advert in the National Autistic magazine (experimental group)
  • The Tourette’s group were recruited from a referral centre in London
  • the ‘normal’ group were a random subject panel from Cambridge
25
Q

What is a strength of this sampling technique?

A
  • results more ecologically valid as participants take the study seriously
  • less likely to suffer from attrition (participants dropping out)
26
Q

What is a weakness of the sampling technique?

A
  • A bias as only a certain type of person would volunteer (confident and outgoing) therefore it is not representative of everyone who has Autism
  • lacks population validity
27
Q

What was the method in this study?

A

quasi-experiment due to naturally occurring IV

28
Q

What is the IV in this study?

A

Whether the participant had Autism, Tourette’s or neither

29
Q

What is the DV in this study?

A

the performance on the Eyes task out of 25

30
Q

What was the setting for each group?

A

Autism - a quiet room in their own home
Tourette’s - a quiet room in a London clinic
‘normal’ - university laboratory

31
Q

What is an outline of the procedure?

A
  • 2 experimental tasks
  • 2 control tasks
32
Q

What was the main experimental task material?

A

The Eyes Task
- 25 black and white magazine photos of the eye region (male and female faces)
- 15x10 cm

33
Q

How long were the photos displayed?

A

3 seconds

34
Q

What were the participants asked in The Eyes Task?

A
  • forced choice
  • what they thought that the person in the photo was thinking or feeling
  • asked to select from two opposite words (one being correct target and one being the incorrect foil)
35
Q

How were the target words generated?

A

4 judges (2 male and 2 female)

36
Q

Which groups completed the Eyes Task?

A

All

37
Q

What was the second experimental task?

A

Happe’s strange stories

38
Q

Which groups completed the strange stories task?

A

Autism and Tourette’s

39
Q

What were the two control tasks?

A

1) Gender Recognition
2) Basic Emotion Task

40
Q

What was the Gender Recognition Task?

A

Took place at the same time as the Eyes Task and participants were asked to identify the gender of the 25 photos that they were shown

41
Q

What was the Basic Emotion Task?

A

Recognising basic emotions based on pictures to ensure that participants did not have a perceptual deficit (as it would be an extraneous variable)

42
Q

What were the 6 emotions in the basic emotions task?

A
  • fear
  • anger
  • sadness
  • happiness
  • surprise
  • disgust
43
Q

What are the strengths of the procedure?

A
  • As in the Eyes Task all participants were shown the exact same type of photo (15x10 black and white photo of eye region) results are more likely to be reliable
  • Causality can be established as extraneous variables (such as perceptual deficits) have been controlled
44
Q

What are the weaknesses of the procedure?

A
  • The Eyes Task lacks mundane realism (not something one would typically do in day-to-day life)
  • lacks ecological validity
45
Q

What was the result from the Eyes Task?

A

Participants with Autism scored significantly lower (16.3) than the ‘normal’ (20.3) and the Tourette’s group scored the highest (20.4)

46
Q

What would the results of the Happe’s strange stories task?

A

Only those with autism made errors on this task

47
Q

What were the strengths of the findings?

A

Gathered quantitative data which was easier to analyse and make comparisons between groups

48
Q

What are the weaknesses of the findings?

A

no qualitative data means that no explanations for behaviour can accurately be drawn

49
Q

What is the conclusion of this study?

A

This study suggests that people with Autism have an impaired theory of mind in comparison to people without Autism. It also indicates that ‘normal’ males find theory of mind more difficult than females and perhaps explains the differences between how they socialise

50
Q

What are the ethical issues within the study?

A
  • results may be socially sensitive
51
Q

What experimental design is used in this study?

A

Matched pairs

52
Q

How were the participants matched?

A

Age and intelligence
