Introduction to Baron-Cohen et al. (1997)

Welcome! In this chapter, we are exploring the contemporary study for the "Understanding Disorders" theme within the Individual Differences area. While the classic study (Freud) looked at a very specific case of a phobia, Baron-Cohen and his team wanted to find a scientific way to measure how adults with Autism or Asperger’s Syndrome perceive the world around them.

Specifically, they were interested in Theory of Mind (ToM). Don't worry if that sounds fancy—it simply means the ability to understand that other people have their own thoughts, feelings, and intentions that might be different from our own. It’s like being able to "read between the lines" during a conversation.

Background: Why Study This?

Before this study, researchers used the "Sally-Anne" test to see if children with autism had a Theory of Mind. However, by the time people with high-functioning autism or Asperger's reach adulthood, they usually pass those simple tests. Baron-Cohen argued that this didn't mean they had a "full" Theory of Mind; it just meant the tests were too easy! He wanted to create a more "adult" and subtle test to see if a ToM deficit still existed in adults.

The Research Method

This study is described as a quasi-experiment. Why "quasi"? Because the researchers didn't randomly put people into groups. The Independent Variable (IV)—whether the person had autism/Asperger’s or not—was naturally occurring.

The Participants (The Sample)

There were three distinct groups of people involved:

  1. Group 1: \( 16 \) individuals with High-Functioning Autism or Asperger’s Syndrome. They were all of normal intelligence.
  2. Group 2: \( 50 \) "normal" age-matched adults (the control group).
  3. Group 3: \( 10 \) adults with Tourette’s Syndrome. This group was vital! Tourette’s also originates in the same part of the brain as autism (the frontal lobe). If Group 1 struggled but Group 3 didn't, it proved that the issues were specific to autism, not just any neurological condition.

Quick Tip: Remember that Group 3 is a "control" for having a neurological disorder. This helps make the study more valid.

The Procedure: What did they do?

Participants completed several tasks, but the most famous one is the Eyes Task.

1. The Eyes Task

Participants were shown \( 25 \) black-and-white photos of eyes. Each photo was shown for \( 3 \) seconds. They had to choose between two opposite mental states (e.g., "concerned" vs. "unconcerned") to describe what the person in the photo was feeling. This is a very subtle task because you only see the eyes, not the whole face.

2. Strange Stories Task

Group 1 and Group 3 also did this task. They were given stories where characters said things they didn't literally mean (like sarcasm or white lies). This was used to check if the Eyes Task was actually measuring Theory of Mind.

3. Control Tasks

To make sure the participants didn't just have bad eyesight or general trouble with faces, they did two control tasks:

  • Gender Recognition: Identifying the gender of the eyes in the photos.
  • Basic Emotion Recognition: Identifying basic emotions (happy, sad, angry) from whole faces.

The Results

The findings were very clear and supported Baron-Cohen’s ideas:

  • Eyes Task Scores: Group 1 (Autism/AS) scored significantly lower (mean of \( 16.3 \) out of \( 25 \)) than Group 2 (mean of \( 20.3 \)) and Group 3 (mean of \( 20.4 \)).
  • Gender & Basic Emotion: There were no differences between the groups. This proves that the Autism group could see and recognize faces just fine; they only struggled with interpreting the subtle mental states.
  • Strange Stories: Group 1 struggled with these stories, while Group 3 (Tourette's) did not.

Did you know? In the "normal" group, women actually scored slightly better on the Eyes Task than men. This led to further theories about "female" vs. "male" brains in later research!

Conclusions

Baron-Cohen concluded that:

  1. Adults with Autism/Asperger’s have a subtle Theory of Mind deficit that lasts into adulthood.
  2. This deficit is not related to general intelligence (IQ), as the participants were of normal intelligence.
  3. The deficit is specific to autism, as the Tourette’s group performed normally on the tests.

Key Takeaway: The "Eyes Task" is a valid way to measure the "Social Sensitivity" component of Theory of Mind in adults.

Linking to Themes and Areas

The Individual Differences Area

This study fits here because it focuses on how individuals vary in their psychological makeup. It looks at a specific group (people with autism) and how their cognitive processes (Theory of Mind) differ from the "typical" population.

Key Theme: Understanding Disorders

Baron-Cohen helps us understand Autism by moving away from just looking at "behaviors" and looking instead at the cognitive causes. It suggests that the social difficulties people with autism face are due to a biological inability to "mind-read" others effectively.

Comparison Note: While Freud (the classic study) used a subjective, non-scientific case study of one boy (Little Hans) to explain a disorder, Baron-Cohen uses a highly controlled, objective, and experimental method to explain a disorder in a larger group of adults.

Common Mistakes to Avoid

  • Don't say the participants were "learning disabled." Group 1 were specifically high-functioning or had Asperger's, meaning they had normal IQs.
  • Don't confuse the control groups. Group 2 was "normal" adults; Group 3 was the Tourette’s group. You need to know why both were used.
  • Don't forget the control tasks. Mentioning the Gender Recognition task is a great way to show you understand how the researchers ensured internal validity.

Quick Review: Can you remember the mean score for the Autism group on the Eyes Task? It was \( 16.3 \). If you can remember that number, you're doing great!
