Baren-Cohen Flashcards
Aim
- To test if the revised version of the ‘Reading the Mind in the Eyes’ test would be successful at differentiating participants with AS or HFA (High Functioning Autism) from the general population.
- To test if there is a negative correlation in a sample of normal adults and between the RET and the AQ.
- To test any sex differences on the RET when normal adults take the test.
Autism Spectrum Disorder
A neurodevelopmental disorder impairing a child’s ability to communicate and interact. Symptoms: repetitive behaviour, little or no eye contact and can’t recognise facial expressions. High Functioning Autism is HFA.
Aspergers syndrome
Autism spectrum disorder that affects language and communication skills. Symptoms: restricted & repetitive behaviours and trouble identifying facial expressions.
Autism spectrum quotient test
self-report questionnaire with scores ranging from 0 to 50. A high score suggests that the person has more autistic traits.
Hypothesis
- Participants with autism will score significantly lower in the RET than the control group.
- Participants with autism will score significantly higher on the AQ test.
- Females in the ‘normal’ group (grp 2 & 3) will score higher on the RET than males in those groups.
- Males in the ‘normal’ group will score higher on the AQ measure than females.
- Scores on the AQ and RET will be negatively correlated.
Sample
Group 1- 15 male with AS/HFA, self-selecting through magazine advert, average IQ is 115
Group 2- control group: 122 adults, 55 men and 67 women, library users in Cambridge
Group 3- control group of students: 103 undergraduates from Cambridge, 53 men and 50 women
Group 4- IQ-matched controls: 14 randomly selected, IQ matched group, average IQ is 116
Research Method, Design
Quasi-experiment, independent groups design
Independent variable
Whether they had AS/HFA or were normal, and gender.
Dependent variable
RET score, AQ score, and gender identification for group 1.
Procedure A: Developing RET
Baren-Cohen and Wheelwright made target words and foils for 36 photos, 8 judges (4 male and 4 female), 5 judges needed to agree on target word, 2 judges could select any single foil word, groups 2 and 3 achieved 100% on judging gender in pilot tests
Procedure B: Implementing the tests
Each test was individually administered in a quiet room at either Cambridge or Exeter. There was no time limit. Each participant was given a practice test and then presented with 36 sets of eyes and 4 possible target words. Group 1 judged the gender of each photo as a control task. Participants in groups 1, 3 & 4 completed the AQ test. They read through the glossary of terms and were asked to ask questions as needed; they could use the glossary during the test.
Results
- Scores ranged from 17 - 35, with a mode of 24.
- Adults with AS/HFA performed significantly worse than other groups for the RET (H1 supported).
- On the AQ test, adults with AS/HFA performed significantly higher than the control groups (H2 supported).
- Females scored higher on the RET (H3 supported).
- There was a significant negative correlation (-0.53) between scores on AQ and RET (H5 supported).
Conclusions
- Current study replicated findings that AS/HFA adults are significantly impaired in identifying the emotions of others.
- Current study replicated findings that AS/HFA adults score significantly higher on the AQ test than the general population.
- There were gender differences found on the RET as females performed better than men. However, it would have been more significant with a greater sample.
The Revised Eye Test was a more sensitive measure of adult social intelligence.
Strengths
- High internal validity
Weakness
- Low ecological validity
- Low generalisability
