  • Baron-Cohen
    • Background
      • 1990 suggested people w autism have a deficit in ToM
    • Aim
      • If individuals on autistic spectrum had deficit in Theory of Mind
      • Develop an advanced test of ToM (Eyes Task)
      • Gender differences in Theory of Mind
    • Participants
      • G1 16 with high autism (4) and Aspergers syndrome (12). MA 28.6 yrs, recruited via clinical resources and ads (13 M and 3 FM) Volunteer sample
      • Group two 50 'normal' adults (25 M 25 FM) MA of 30 yrs. selected at random via a subject panel held at uni Random sample
      • G3 10 with Tourrette syndrome (8 M and 2 FM) MA 27.77 years. Recruited via tertiary referral centre  Snowball sample
      • G2 included as a control to see the normal performance on ET. G3 included as similar to Autism.
    • Hypothesis
      • 1) Autism and AS would show significant impairment on Eyes Task 2) Females will perform better than Males on ET
    • Method and Design
      • Quasi-experiment. IV naturally occurring. IV: type of person. DV: performance on the eyes task (out of 25).
    • Procedure
      • Participants tested in quiet environment. Eyes Task, Strange stories, Gender recognition task in randomised order (control)
    • Results
      • Eyes Task: Autism and As mean score 16.3 Normal: 20.3 Tourette: 20.4
      • Gender of normal group: M 18.8        FM 21.8
    • Conclusions
      • Provided evidence that Autism and As possess impaired theory of mind
      • Theory of  Mind deficits are independent of intelligence
    • Evaluation
      • ETHICS: protected from harm and some done at homes. Increases replicability
      • VALIDITY: participants in groups matched for age and intelligence levels
        • Inclusion of strange stories confirmed that it was ToM that the were measuring in ET
        • Tests administered in different order, prevented order effects. Took them in quiet room contolled peer pressure or noise (possible extraneous variables
        • ISSUES: in ET had to choose one of two options- could be successful guesses
      • RELIABILITY:  Eyes task checked by 8 ppl. 25/25 in normal groupas min no required to establish reliable effect
      • USEFULNESS:  useful info about AS and autism and treatments in the future
