Welcome to the Study of Individual Differences: Understanding Disorders
Hello there! Welcome to one of the most fascinating parts of your Psychology course. In this section, we are diving into Individual Differences, specifically focusing on how psychologists try to understand "disorders."
Why do we study this? Because every human mind is unique! By looking at how some people experience the world differently—whether through phobias or conditions like Autism—we learn more about the "typical" human mind and how to support those who struggle. Don't worry if some of the theories seem a bit strange at first (especially Freud!); we'll break them down step-by-step.
Quick Review: What are "Individual Differences"?
Instead of looking for general laws that apply to everyone (like how memory works), this area focuses on what makes us unique. It looks at personality, intelligence, and mental health.
1. The Classic Study: Freud (1909) - Little Hans
Our first stop is the "Grandfather of Psychoanalysis," Sigmund Freud. This study is a case study of a young boy named Hans who developed a phobia of horses.
What was Freud trying to prove?
Freud believed that our childhood experiences and unconscious desires shape who we are. He specifically wanted to find evidence for the Oedipus Complex.
Analogy: Imagine your mind is like an iceberg. The part above water is what you know (conscious), but the giant part underwater is what drives you (unconscious). Freud wanted to look under the water.
Key Concepts to Remember:
• The Oedipus Complex: Freud's theory that young boys have unconscious feelings for their mother and see their father as a rival.
• Displacement: Taking a fear you have (like being punished by your Dad) and "moving" it onto something else (like a horse).
• The Phobia: Hans was terrified that a horse would fall down or bite him. Freud argued the horse represented his father (the dark blinkers were like his father’s glasses/moustache).
How did he do it?
This wasn't a lab experiment! It was a longitudinal case study. Interestingly, Freud didn't actually treat Hans himself most of the time; Hans's father sent notes to Freud, and Freud interpreted them.
What did he find?
Hans eventually "resolved" his phobia through dreams about having a bigger family and a "plumber" replacing his "widdler" (penis) with a bigger one. Freud interpreted this as Hans moving past his fear of his father and identifying with him instead.
Common Mistake to Avoid:
Students often think Freud met with Hans every day. In reality, Freud only met Hans once! The rest was done through letters from the father.
Key Takeaway: Freud believed mental "disorders" (like phobias) are caused by unresolved conflicts in our childhood that are hidden in our unconscious minds.
2. The Contemporary Study: Baron-Cohen et al. (1997)
Now, let's fast-forward almost 90 years. We move from the "unconscious mind" to how the brain processes information. Baron-Cohen wanted to understand Autism in adults.
The Big Idea: Theory of Mind (ToM)
Theory of Mind is like a "social GPS." It is the ability to understand that other people have different thoughts, feelings, and intentions than you do.
Example: If you see a friend crying, your ToM tells you "They are sad." If you lack ToM, you might just see "water on a face" and not understand the emotion behind it.
The "Eyes Task" Experiment
Baron-Cohen felt that existing tests for ToM were too easy for adults with Asperger’s Syndrome (AS) or High-Functioning Autism (HFA). So, he created the Eyes Task.
• The Method: A quasi-experiment.
• The Task: Participants looked at 25 photos of just the eyes of different people and had to choose between two emotions (e.g., "concerned" vs. "unconcerned").
• The Groups: He compared adults with AS/HFA to "normal" adults and adults with Tourette’s Syndrome.
What were the results?
• The AS/HFA group scored significantly lower (about 16/25) than the "normal" group (about 20/25).
• Interestingly, females in the normal group generally scored better than males.
• The Tourette’s group performed similarly to the normal group, showing that a lack of ToM is specific to Autism, not just any neurological condition.
Did you know?
Baron-Cohen’s work led to the idea that Autism might be an "extreme male brain," as he found that males (even those without Autism) generally scored slightly lower on empathy-based tasks than females.
Key Takeaway: This study suggests that a core part of Autism is a cognitive deficit in Theory of Mind—making it hard to "read" the social world through people's eyes.
3. Comparing the Two Studies
Don't worry if this seems like comparing apples and oranges! That's actually the point. Here is how they stack up:
How are they similar?
• Both aim to understand a disorder (Phobias vs. Autism).
• Both look at Individual Differences (why Hans is different from other kids; why AS adults are different from "normal" adults).
How are they different?
• Methodology: Freud used a case study (one person, lots of depth). Baron-Cohen used a quasi-experiment (lots of people, looking for patterns).
• Nature vs. Nurture: Freud focused on nurture (childhood experiences and parents). Baron-Cohen leans toward nature (biological differences in how the brain works).
• Data: Freud gathered qualitative data (descriptions, stories). Baron-Cohen gathered quantitative data (scores on the Eyes Task).
Quick Review Box:
Classic (Freud): Focuses on the unconscious, parents, and deep symbols. Highly subjective.
Contemporary (Baron-Cohen): Focuses on brain processing, "Theory of Mind," and objective testing.
4. Methodological Issues (The "Checklist")
When you write about these in your exam, you need to "evaluate" them. Think of these as the "pros and cons."
Reliability (Is it consistent?)
• Freud: Very low. You can't really "replicate" Little Hans. Every child’s dreams are unique!
• Baron-Cohen: High. The Eyes Task is a standardized test that can be given to anyone in the same way.
Validity (Is it measuring what it claims to?)
• Freud: Critics say Freud was biased. He looked for things that proved his theory and ignored the rest.
• Baron-Cohen: Does the "Eyes Task" really measure real-life social skill? In real life, people move and speak; they aren't just a static photo of eyes! This is a question of ecological validity.
Ethnocentrism (Is it "culture-bound"?)
• Freud: Very ethnocentric. He studied a middle-class Austrian boy in the 1900s and assumed all children in the world were exactly the same.
• Baron-Cohen: The task used Western eyes and English words. People from different cultures might interpret "concerned" eyes differently.

Final Summary: The Big Picture
The "Issues in Mental Health" or "Understanding Disorders" theme shows us how psychology has evolved. We moved from Freud’s "detective work" into the hidden unconscious, toward Baron-Cohen’s scientific approach to how the brain processes the social world. Both help us understand that there is no single "right" way for a human mind to work—just different ways of experiencing our world!
Great job getting through these notes! Take a break, and when you're ready, try to explain "Theory of Mind" to a friend using the "Social GPS" analogy. You've got this!
