Welcome to the World of Psychological Pairs!
In this chapter, we are going to explore one of the most exciting parts of your OCR AS Level Psychology course: Core Studies in their Pairs. Think of this like a "then and now" comparison. For every big idea in psychology, we have a Classic Study (a famous, older piece of research that started the conversation) and a Contemporary Study (a more modern piece of research that adds more detail or looks at things in a new way).
Don't worry if this seems like a lot to remember at first! We’ve broken it down by the five main areas of psychology. By comparing them, you'll see how psychology has grown and how our understanding of humans has changed over time. Let’s dive in!
1. Social Psychology: Responses to People in Authority
The Big Idea: Why do we do what we are told, even if it feels wrong? And why do some people have the courage to say "no"?
The Pair: Milgram (1963) & Bocchiaro et al. (2012)
How are they similar?
Both studies were conducted in a controlled laboratory setting at a university. Both researchers were interested in how a situation (like being in a room with a scientist) can make people behave in ways they didn't expect. Both studies also used a volunteer sample (people who signed up through an advert).
How are they different?
Milgram focused on obedience—he wanted to see if people would give "electric shocks" to a stranger just because an authority figure told them to. Bocchiaro looked at disobedience and whistle-blowing (reporting someone for doing something wrong). Also, Bocchiaro used both men and women, whereas Milgram’s classic study only used men.
How did our understanding change?
Milgram taught us that people are surprisingly obedient to authority. Bocchiaro extended this by showing that even if we think we would be the hero who says "no," most of us still obey. It also showed that "whistle-blowing" is actually very rare and difficult to do!
Understanding Diversity:
Bocchiaro’s study included women and students, which makes the findings more generalisable (applicable to more types of people) than Milgram’s study of just adult males.
Quick Review: The "Authority" Pair
Milgram: Obedience + Electric shocks + Men only.
Bocchiaro: Whistle-blowing + Marketing task + Men and women.
2. Cognitive Psychology: Memory
The Big Idea: Is our memory like a perfect video recording, or can it be changed and influenced by our environment?
The Pair: Loftus and Palmer (1974) & Grant et al. (1998)
How are they similar?
Both are laboratory experiments that use students as participants. They both look at how cognitive processes (how we think and remember) can be influenced by outside factors.
How are they different?
Loftus and Palmer looked at how leading questions (using words like "smashed" vs. "hit") can actually distort or change a memory of a car crash. Grant et al. looked at context-dependent memory—the idea that you remember things better if you are in the same environment where you learned them (e.g., studying in silence and taking the test in silence).
How did our understanding change?
Loftus showed us that memory is reconstructive (we build it back up, and sometimes we get the parts wrong). Grant added to this by showing that memory isn't just about what happens after an event, but also about the physical environment we are in when we try to remember.
Understanding Diversity:
Both studies used students, which is a very specific "type" of person. While this helps us understand how the human brain works generally, it doesn't tell us much about how memory might differ in older adults or people from different cultures.
Quick Review: The "Memory" Pair
Loftus: Leading questions + Memory distortion.
Grant: Study/Test environment + Context cues.
3. Developmental Psychology: External Influences on Children’s Behaviour
The Big Idea: How do children learn to behave? Do they just copy what they see, or can we "train" them to behave better using rewards?
The Pair: Bandura et al. (1961) & Chaney et al. (2004)
How are they similar?
Both studies look at how the environment influences a child's behavior. Both studies involve observing children and measuring how their actions change based on what they experience.
How are they different?
Bandura looked at Social Learning Theory—specifically, how children copy aggression after watching an adult hit a Bobo doll. It’s quite a dark look at behavior! Chaney looked at Operant Conditioning—specifically, how a "Funhaler" (a medical inhaler with toys on it) can use positive reinforcement to make children more likely to take their asthma medicine.
How did our understanding change?
Bandura showed us that children are like sponges—they imitate what they see. Chaney moved this forward by showing that we can use these "learning rules" to create practical solutions for health problems, making life better for children and parents.
Understanding Diversity:
Chaney’s study looks at children with a specific medical condition (asthma), which adds to our understanding of how different groups of children respond to their environment.
Quick Review: The "Learning" Pair
Bandura: Copying adults + Aggression + Bobo Doll.
Chaney: Rewards + Health behavior + Funhaler.
4. Biological Psychology: Regions of the Brain
The Big Idea: Does every part of the brain have a specific job? How do different "rooms" in the brain talk to each other?
The Pair: Sperry (1968) & Casey et al. (2011)
How are they similar?
Both researchers believe that our behavior is caused by physical processes in the brain. They both looked at specific regions of the brain and what happens when they function differently.
How are they different?
Sperry studied "Split-Brain" patients—people who had surgery to cut the link between the two halves of their brain. It was a quasi-experiment because he couldn't "give" people the surgery himself! Casey used modern fMRI scans to look at the brains of "High Delayors" and "Low Delayors" (people who can or cannot resist eating a marshmallow/cookie).
How did our understanding change?
Sperry showed us lateralisation (the left and right sides of the brain do different things). Casey moved us into the 21st century by showing how specific regions (like the ventral striatum) control our impulses and willpower, even 40 years after we were kids!
Understanding Diversity:
Casey’s study is longitudinal (it followed the same people for decades). This helps us understand how individual differences in our biology stay with us from childhood into adulthood.
Quick Review: The "Brain" Pair
Sperry: Left vs. Right brain + Split-brain surgery.
Casey: Willpower + fMRI scans + Marshmallows.
5. Individual Differences: Understanding Disorders
The Big Idea: How do we explain why some people have different mental experiences or disorders? Is it about their childhood or their biology?
The Pair: Freud (1909) & Baron-Cohen et al. (1997)
How are they similar?
Both studies attempt to explain a "disorder" or a different way of being (Freud looked at phobias; Baron-Cohen looked at Autism). They both want to understand what is happening "under the hood" of the person’s mind.
How are they different?
Freud used a case study of one boy (Little Hans) and suggested his phobia of horses was caused by subconscious feelings about his parents. Baron-Cohen used a quasi-experiment with many adults and suggested that Autism is linked to a lack of "Theory of Mind" (difficulty "reading" the emotions of others through their eyes).
How did our understanding change?
Psychology moved from subjective theories (Freud’s ideas which were hard to prove) to objective, scientific testing (Baron-Cohen’s "Eyes Task"). We now understand disorders like Autism as cognitive deficits rather than emotional problems from childhood.
Understanding Diversity:
Baron-Cohen specifically looked at adults with Asperger’s Syndrome or High-Functioning Autism. This helps us understand that people with disorders are individuals with specific cognitive profiles, not just "broken" versions of typical people.
Quick Review: The "Disorders" Pair
Freud: Little Hans + Dreams + Phobias.
Baron-Cohen: Autism + Eyes Task + Theory of Mind.
Summary: The Big Picture
Don't worry if this seems like a lot of names! The key is to remember the theme. For each pair, ask yourself:
1. What was the Classic study’s main point?
2. How did the Contemporary study make that point better, more modern, or more inclusive?
By comparing them, you are acting like a real psychologist—seeing how science evolves over time!
Key Takeaway: Psychology has moved from studying mostly men to studying everyone; from guessing about the mind to using brain scans; and from watching behavior to finding ways to fix real-world problems. You've got this!
