Welcome to the "Big Picture" of Psychology!
Welcome! This chapter is where everything in your Psychology course starts to come together. Think of it as the "lens" through which psychologists view the world. Instead of just looking at one study, we are going to look at the Areas, Perspectives, Issues, and Debates that shape how we understand human behavior.
Don't worry if some of these terms sound a bit "academic" at first. By the end of these notes, you'll see that these are just different ways of answering the same question: "Why do people do what they do?"
1. The Five Main Areas of Psychology
Psychology is a huge subject, so we break it down into five main areas. Each area has its own set of "key principles" (the main rules they follow).
The Social Area
The Main Idea: This area looks at how our behavior is influenced by the people around us and the environment we are in. It suggests that we aren't just "born that way," but that we change depending on who is watching.
Core Study Examples: Milgram (obedience to authority) and Piliavin et al. (helping behavior in the subway).
Real-World Analogy: Think about how you act differently when you are with your friends versus when you are sitting in an assembly with your Headteacher. That change in behavior is what social psychologists study!
The Cognitive Area
The Main Idea: This area views the human mind like a computer. It focuses on "internal mental processes" like memory, perception, and attention. They believe that to understand behavior, we must understand how the mind processes information.
Core Study Examples: Loftus and Palmer (how eyewitness memory can be changed) and Grant et al. (how we remember better in the same environment where we learned).
Key Takeaway: If the Social area is about the "room" you are in, the Cognitive area is about the "software" running in your head.
The Developmental Area
The Main Idea: This area studies how we change and grow throughout our lives. It suggests that our behavior is a result of nature (genes) and nurture (learning), and that childhood experiences are huge for our future selves.
Core Study Examples: Bandura et al. (learning aggression by watching adults) and Chaney et al. (using rewards to help children use asthma inhalers).
The Biological Area
The Main Idea: This area looks at the "hardware." It argues that behavior is caused by physical things like our brain structure, genes, hormones, and neurochemistry.
Core Study Examples: Sperry (split-brain research) and Casey et al. (how brain activity relates to self-control/delayed gratification).
The Individual Differences Area
The Main Idea: Most areas of psychology try to find "general rules" for everyone. This area does the opposite! it focuses on what makes us unique and how people differ from the "average."
Core Study Examples: Freud (studying a specific phobia in one boy) and Baron-Cohen et al. (looking at how people with Autism process emotions differently).
Quick Review Box: The 5 Areas
1. Social: People & Environment.
2. Cognitive: Mental processes (Memory).
3. Developmental: Change over time.
4. Biological: Brain & Body.
5. Individual Differences: What makes us unique.
Memory Aid: Use the mnemonic "S.C.B.I.D" (Social, Cognitive, Biological, Individual Differences, Developmental) – "Some Cats Believe In Dogs."
2. Perspectives in Psychology
A perspective is slightly different from an area. It’s a specific "school of thought." The OCR syllabus focuses on two main ones:
The Behaviourist Perspective
The Core Principle: Behaviourists believe we are born as a "tabula rasa" (a blank slate). Everything we do is learned from our environment through rewards, punishments, and observation. They only care about behavior they can actually see.
Studies to use: Bandura (learning through observation) and Chaney (learning through rewards/positive reinforcement).
The Psychodynamic Perspective
The Core Principle: Founded by Sigmund Freud, this perspective believes our behavior is driven by our unconscious mind (thoughts we aren't even aware of) and our childhood experiences.
Study to use: Freud (Little Hans).
Don't worry if this seems tricky! Just remember: Behaviourists look at what you do (learned behavior), while Psychodynamic psychologists look at what you feel deep down (unconscious mind).
3. Issues in Psychology
Issues are the "problems" or "questions" researchers have to deal with when they do a study.
1. Ethical Issues: Psychologists must follow rules to protect participants. This includes informed consent, right to withdraw, and confidentiality.
Example: Milgram’s study was very unethical because it caused participants a lot of stress!
2. Usefulness of Research: Does the study actually help society?
Example: Loftus and Palmer’s study is very useful because it changed how the police interview witnesses.
3. Socially Sensitive Research: These are studies on "touchy" subjects that might cause stigma or offend groups of people (like studies on intelligence, mental health, or obedience).
4. The Great Debates
Psychologists love to argue! These five debates are the "big fights" in the subject.
Nature vs. Nurture
Is our behavior caused by our genes and biology (Nature) or by our upbringing and environment (Nurture)?
Example: Sperry (Nature) vs. Bandura (Nurture).
Freewill vs. Determinism
Do we choose our actions (Freewill), or is our behavior "pre-programmed" by our biology or our past (Determinism)?
Example: Milgram suggests our situation "determines" our obedience, leaving little room for freewill.
Reductionism vs. Holism
Reductionism is breaking complex behavior down into tiny, simple pieces (like just looking at one gene). Holism is looking at the "whole person" and all the different things that might affect them.
Individual vs. Situational Explanations
Is a person acting this way because of their personality (Individual) or because of the situation they are in (Situational)?
Example: In Piliavin’s study, people helped because of the situation (being stuck on a train) rather than just being "nice people."
Psychology as a Science
Is Psychology a "hard science" like Chemistry? To be a science, research must be objective (unbiased), replicable (can be done again), and falsifiable (can be proven wrong).
Key Takeaway for Debates: Most psychologists today believe the answer is usually "a bit of both." For example, we are influenced by our genes (Nature) AND our environment (Nurture).
Common Mistakes to Avoid
Mistake 1: Confusing the Individual Differences Area with the Individual vs. Situational Debate.
The fix: The Area is a category of study (like Autism or Phobias). The Debate is a question about whether personality or the situation causes behavior.
Mistake 2: Thinking a study can only belong to one area.
The fix: Studies often overlap! Bandura is in the Developmental area, but it is also a perfect example of the Behaviourist Perspective.
Quick Review: The Debates
- Nature/Nurture: Biology vs. Learning.
- Freewill/Determinism: Choice vs. No choice.
- Reductionism/Holism: Simple parts vs. Whole picture.
- Individual/Situational: My personality vs. My surroundings.
- Science: Is it objective and measurable?
