Research methods and ethics - Psychology A Level Study Notes
Overview
Imagine you want to know if playing video games makes people better at solving puzzles. How would you find out for sure? You can't just guess, right? You need a plan, a way to test your idea fairly and accurately. That's exactly what **research methods** are all about in psychology – they are the tools and strategies psychologists use to investigate how our minds work and why we behave the way we do. But it's not just about getting answers; it's also about doing it in a way that's fair and doesn't hurt anyone. This is where **ethics** come in. Think of it like a superhero code of conduct. Psychologists have a responsibility to protect the people they are studying, making sure they are treated with respect and their privacy is kept safe. Without good research methods and strong ethics, any 'discoveries' we make might not be true, or worse, they could cause harm. Learning about research methods and ethics is super important because it helps you understand how we know what we know about psychology. It also teaches you to spot good science from bad science, whether you're reading a news article or watching a documentary. It's like having a special superpower to tell if information is reliable!
What Is This? (The Simple Version)
Imagine you're trying to figure out if your new plant grows better with classical music or heavy metal. You wouldn't just guess, would you? You'd set up an experiment: one plant gets classical, one gets heavy metal, and maybe one gets no music at all (that's your control group – a baseline for comparison!). You'd measure their growth over time, making sure everything else (like sunlight and water) is exactly the same.
That's basically what research methods are in psychology! They are the different ways psychologists collect information and test their ideas (called hypotheses – educated guesses). Just like you have different tools for different jobs (a hammer for nails, a screwdriver for screws), psychologists have different methods for different questions. Some methods are great for finding out what people do, while others are better for figuring out why they do it.
And ethics? That's like the rulebook for doing your plant experiment. You wouldn't pour acid on one plant just to see what happens, right? That would be mean and unethical! In psychology, ethics are the moral guidelines that make sure researchers treat people fairly, keep them safe, and respect their privacy. It's all about doing science kindly and responsibly.
Real-World Example
Let's say a psychologist wants to know if listening to upbeat music before a test helps students score higher. How would they research this ethically?
- The Idea: The psychologist thinks upbeat music might improve test scores.
- The Plan (Method): They decide to do an experiment. They get a group of students and split them randomly into two smaller groups. One group listens to upbeat music for 10 minutes before a test (the experimental group), and the other group sits in silence for 10 minutes (the control group). Both groups then take the same test.
- Ethical Steps:
- Informed Consent: Before anything starts, the psychologist explains exactly what will happen to all the students. They tell them they'll listen to music (or sit in silence) and then take a test. They also tell them they can say 'no' and leave at any time without getting into trouble. This is like getting permission from your parents before you go to a friend's house.
- Confidentiality: The psychologist promises not to share anyone's individual test scores or names. They'll only talk about the average scores of the groups. This keeps everyone's information private, like keeping your diary a secret.
- Debriefing: After the test, the psychologist explains the real purpose of the study (to see if music helps) and answers any questions. If anyone felt stressed, they'd offer support. It's like explaining the magic trick after you've performed it.
By following these steps, the psychologist can gather information in a scientific way while also protecting the students involved.
Different Ways to Investigate (Research Methods)
Just like a detective has different tools (magnifying glass, fingerprint kit), psychologists have various **research methods** to uncover truths about the mind. 1. **Experiments:** This is like a controlled science experiment in a lab. Researchers change one thing (the **independent variable**, e....

Exam Tips
- →When asked to 'outline' a research method, give its definition and one key feature or advantage/disadvantage.
- →For ethical issues, always explain *why* it's an issue (e.g., 'lack of informed consent is an issue because participants don't know what they're agreeing to') and *how* to deal with it (e.g., 'provide a consent form').
