Welcome to the "Key Questions" in Psychology!

Ever wondered why people riot, or why we find it so hard to stop eating chocolate even when we know it's bad for us? That is exactly what this part of the course is about! In Psychology (8PS0), Key Questions take the theories you’ve learned in the classroom and apply them to real-world problems. This makes Psychology come alive because it shows how your studies can actually help society.

Don’t worry if some of the theories feel heavy at first. We are going to break these down into bite-sized pieces and show you exactly how to link a real-life issue to psychological research. Think of yourself as a detective using "clues" (theories) to solve "cases" (social issues).


1. Social Psychology: Prejudice and Heroism

The Question: How can social psychology help us understand and reduce prejudice, or explain why some people become heroes?

In Social Psychology, we look at how the people around us influence our behavior. Two big areas you can choose to talk about are crowd behavior (like rioting) or how to stop people from being prejudiced against others.

Linking Theory to the Issue

To answer this question, you need to use your "Social Toolkit":

Social Identity Theory (Tajfel and Turner): This explains that we naturally divide the world into "Us" (the In-group) and "Them" (the Out-group). To feel better about ourselves, we often put the out-group down.
Realistic Conflict Theory (Sherif): This says prejudice happens when two groups are fighting over the same thing, like jobs or land (limited resources).
Agency Theory (Milgram): This can explain why people in a crowd might do bad things—they enter an agentic state, feeling they are just following the crowd or a leader, and don't feel personally responsible.

Real-World Example

Imagine two rival football teams. The fans might shout insults at each other (Social Identity Theory) because they want their "group" to feel superior. If there is only one trophy to win (limited resource), the hostility gets worse (Realistic Conflict Theory).

Quick Review: How to reduce prejudice?

Psychologists suggest superordinate goals—tasks that require both groups to work together to succeed. If the rival fans had to work together to fix a broken bus so everyone could get home, their prejudice would likely drop!

Key Takeaway: Prejudice isn't just "being mean"; it’s often a result of how our brains categorize groups and compete for resources.


2. Cognitive Psychology: Memory, Dementia, and Dyslexia

The Question: How can our understanding of memory help people with dementia or dyslexia?

Cognitive psychology compares the human mind to a computer. If we know how the "software" (memory) works, we can help when it starts to glitch.

Linking Theory to the Issue

The Multi-Store Model (Atkinson and Shiffrin): This tells us that information must be rehearsed to move from Short-Term Memory to Long-Term Memory. For someone with dementia, this "transfer" process is often broken.
Working Memory Model (Baddeley and Hitch): This explains how we process live information. People with dyslexia often have a smaller phonological loop (the part that deals with sounds), making it hard to hold onto spoken instructions.
Reconstructive Memory (Bartlett): We use schemas (mental shortcuts) to fill in gaps in our memory. This explains why patients with memory loss might "confabulate" or make up stories that make sense to them, even if they aren't true.

Memory Aid: The Filing Cabinet

Think of Long-Term Memory as a filing cabinet. Dementia is like the labels falling off the folders. Dyslexia is more like having a very small desk (Working Memory) where you can only fit two or three papers at a time before they start falling off.

Did you know?

Cognitive psychologists have developed "Memory Cafes" for dementia patients. They use old photos and music to trigger Episodic Memories (memories of life events) that might still be stored deep in the Long-Term Memory store!

Key Takeaway: By knowing which "store" of memory is struggling, we can create better tools (like color-coding for dyslexia) to help people learn and live better.


3. Biological Psychology: Addiction and Aggression

The Question: Is aggression caused by nature or nurture? Or, how effective is drug therapy for addiction?

This section looks at the "hardware" of the body—our brain structure, hormones, and DNA.

Linking Theory to the Issue

Neurotransmitters: Chemicals like Dopamine are linked to the "reward center" of the brain. Drugs like heroin hijack this system. Drug therapies like Methadone work by mimicking the drug but in a safer, controlled way to reduce withdrawal.
Brain Structure: The Pre-frontal Cortex is like the brain's "brakes." If it’s damaged or underactive, a person might be more aggressive because they can’t control their impulses.
Evolution: This theory suggests aggression was once useful for survival (protecting mates or food), which is why it’s still in our genetics today.

Step-by-Step: The Methadone Process

1. A person is addicted to heroin (which causes a massive dopamine "high").
2. Quitting causes painful withdrawal because the brain stops making its own feel-good chemicals.
3. Methadone is prescribed. It binds to the same receptors in the brain but doesn't cause the same "high."
4. This stabilizes the patient so they can focus on therapy and avoid illegal activity.

Common Mistake to Avoid

Don't say that biology is the ONLY cause of behavior. In Psychology, we usually find it's an interaction between our genes (nature) and our environment (nurture).

Key Takeaway: Biological psychology takes the "blame" out of issues like addiction and aggression by showing they are often related to physical brain chemistry.


4. Learning Theories: Anorexia and Phobias

The Question: Do celebrities cause anorexia? Or, how can we cure a fear of flying?

Learning theories suggest we are born as a "blank slate" and everything we do is learned from our environment.

Linking Theory to the Issue

Social Learning Theory (Bandura): We observe role models (like celebrities). If they are rewarded for being thin (fame, money), we might imitate that behavior to get the same vicarious reinforcement.
Classical Conditioning (Pavlov): This explains phobias. If a plane trip (Neutral Stimulus) is paired with turbulence/fear (Unconditioned Stimulus), the plane becomes a Conditioned Stimulus that triggers a fear response.
Operant Conditioning (Skinner): If someone avoids a flight and feels instant relief, that negative reinforcement makes them more likely to avoid flying again in the future.

Memory Aid: ARRM

To learn a behavior from a role model, you need:
A - Attention (You notice them)
R - Retention (You remember it)
R - Reproduction (You are physically able to do it)
M - Motivation (You want the reward they have)

Real-World Example

Airline companies often offer "Flying without Fear" courses. They use Systematic Desensitisation, where they slowly teach you to relax while looking at photos of planes, then sitting in a seat, and finally taking a short flight. You are "unlearning" the fear!

Key Takeaway: If a behavior is learned, it can be unlearned. This gives us great power to treat phobias and understand social pressures.


How to Answer "Key Question" Exam Prompts

When you see a question about a "Key Question" in your exam, follow this simple recipe:

1. Identify the Question: State clearly what the issue is (e.g., "The key question is whether the media causes eating disorders").
2. Describe the Issue: Explain why it's a problem for society today (e.g., "It costs the NHS millions and affects young people's health").
3. Apply Theory (The Clues): Use 2-3 psychological theories to explain the issue (e.g., "Social Learning Theory suggests...").
4. Conclusion: Summarize how psychology helps us solve the problem or understand it better.

Don't worry if this seems tricky at first—once you've practiced a few, you'll start seeing psychological theories everywhere in the news!
