  • Baron Cohen
    • Aim/method
      • Why adults with autism have problems with social relationships
      • Develope a valid theory of mind test
      • Quasi experiment using matched pairs design
    • Participants
      • Tourettes
        • 8 male, 2 female
        • Mean IQ 103.5
        • Recruited among attendees at a referral centre in London
        • Similar to autistic used to see if mind blindness was specific to their impairment rather than developmental disorders
          • Experienced since childhood
          • Disrupts schooling and relationships
          • associated with abnormalities in frontal region of brain
      • Autistic
        • 13 male 3 female, 4 with autism 12 with Aspergers syndrome
        • Mean IQ 105.31
        • recruited from adverts in national autistic society magazine
      • Clinically normal
        • 25 female and 25 males
        • randomly selected from cambridge area (not the uni)
        • IQ above 85
    • Procedure
      • Eye task
        • Shown 15 black and white photos from magazines for 3 secs
          • All 15 by 10cm showed same region of face
          • Four judges generated word pairs to describe expression (serious playful)
            • Blind tested by 8 clinically normal adults 100% in agreement
        • Asked which word best describes what this person is thinking or feeling?
          • For each correctly guessed target word ppt would score a point
      • Happe's strange stories
        • told some stories and asked to judge the physical or mental state of the characters
        • A positive correlation between eye task and strange stories would establish concurrent validity
          • When one test is compared to another if the results are similar the results are valid
      • Gender recognition
        • Same 25 photos in eye task
          • Asked to identify gender
        • Involved making a social judgement without mind reading
          • check if deficits on eye task could be due to general deficits in face or social perception
      • Basic emotion recognition
        • Shown 6 black and white photos displaying whole face with basic emotions
          • e.g. sad, happy
        • check whether deficits on eye task could be due to a deficit in basic emotion recognition
      • Tested individually in a quiet room in lab, clinic or own home
        • Tests presented in random order
    • Results
      • Eye task
        • Autistic 16.3
        • Normal 20.3
        • Tourettes 20.4
        • Normal male 18.8
        • Normal female 21.8
      • Gender control
        • Autisitic 24.1
        • Normal 23.3
        • Tourettes 23.7
        • Normal male 24
        • Normal female 23.8
    • Conclusion
      • Evidence of deficit of subtle mind reading among st intelligent autistic adults
      • Eye task is a valid measure of theory of mind
