Research methods and ethics - Psychology IB Study Notes
Overview
Imagine you want to figure out if eating chocolate before a test makes you smarter. How would you do it fairly and correctly, without tricking anyone? That's what research methods are all about! They are like the secret recipes scientists use to find answers to big questions about how our minds work. But it's not just about finding answers; it's also super important to be kind and fair to everyone involved. That's where ethics come in. Ethics are like the golden rules that make sure no one gets hurt or feels uncomfortable during a study. Together, research methods and ethics help us learn amazing things about people in a way that's honest and respectful. Understanding these ideas helps you not only in psychology but also in everyday life. You'll be able to spot if a news story about a new 'superfood' is based on good science or just a silly claim!
What Is This? (The Simple Version)
Imagine you're trying to figure out if your new plant grows better with sunlight or in the shade. You wouldn't just guess, right? You'd probably put one plant in the sun and one in the shade and watch them. That's basically what research methods are: the different tools and plans scientists use to study how people think, feel, and act.
Think of it like a detective's toolkit. Some tools are for observing (watching carefully), some are for asking questions, and some are for trying out different things to see what happens. Each tool helps us find clues to understand the human mind.
Now, ethics are like the 'fair play' rules in a game. Just like you wouldn't cheat or be mean to your teammates, scientists have rules to make sure their studies are fair, safe, and respectful to everyone who helps them. They make sure no one gets tricked or feels bad just for the sake of science. It's about being a good person while doing good science!
Real-World Example
Let's say a famous chocolate company wants to know if eating their new 'Brain Boost Bar' actually makes kids better at math. They can't just say it does without proof, right? That's where research methods and ethics come in.
- The Research Method (How they'd find out): They might gather 100 kids. They'd give 50 kids the 'Brain Boost Bar' every day for a month (this is called the experimental group – the ones getting the special treatment). The other 50 kids would get a regular chocolate bar that looks exactly the same but doesn't have the special ingredients (this is the control group – they don't get the special treatment, so we can compare).
- The Measurement: Before and after the month, all kids would take a math test. If the 'Brain Boost Bar' group's scores go up much more than the control group's, then maybe it works!
- The Ethics (Making sure it's fair and safe):
- Informed Consent: Before starting, the chocolate company would need to explain exactly what they're doing to the kids' parents and get their permission. No tricks!
- Right to Withdraw: The kids (or their parents) should be able to say 'I don't want to do this anymore' at any time, without getting into trouble.
- Confidentiality: The company shouldn't tell everyone which kid ate which bar or what their individual scores were. Keep their information private.
- Debriefing: After the study, they should tell everyone what they were trying to find out and thank them for participating. If any kid got upset, they should make sure they feel okay again.
This way, they get their answer fairly and respectfully.
Different Ways to Investigate (Research Methods)
Just like there are different ways to find out if a new video game is fun (watching someone play, trying it yourself, reading reviews), there are different **research methods** in psychology. Each one is good for different types of questions. 1. **Experiments:** This is like the chocolate bar exam...

Key Concepts
- Research Methods: The different tools and plans scientists use to study how people think, feel, and act.
- Ethics: The golden rules or moral principles that guide scientists to ensure studies are fair, safe, and respectful to participants.
- Experiment: A research method where one thing is changed (independent variable) to see if it causes a change in another thing (dependent variable).
- Independent Variable (IV): The one thing a researcher changes or manipulates in an experiment (e.g., the 'Brain Boost Bar').

Exam Tips
- →When asked about research methods, always think about *why* a particular method (like an experiment or a case study) is chosen – what kind of question does it best answer?
- →For ethics questions, don't just list the rules; explain *why* each rule is important and *how* a researcher would follow it in a real study.
