Core studies develop understanding of why psychological research is conducted
AS Level Core Studies: Why Do We Conduct Psychological Research? 🤔
Research is the backbone of psychology. Think of it as a detective story: we gather clues (data), follow a method (theory), and solve the mystery (understand human behaviour). In this section, we’ll explore why psychologists do research, the different ways they do it, and how you can ace the exam questions.
Why Research Matters 🧩
Psychologists ask questions like:
- How does memory work? 🧠
- Why do people feel anxious in crowds? 😰
- Can a new therapy help depression? 💡
By answering these, we can:
- Improve mental health treatments.
- Design better schools and workplaces.
- Predict and prevent social problems.
- Build a solid evidence base for policy decisions.
The Research Process 🔬
A typical study follows these steps:
- Ask a clear, testable question.
- Review existing literature.
- Choose a research method.
- Collect and analyse data.
- Draw conclusions and report findings.
Common Research Methods 📊
| Method | Example | Strengths | Weaknesses |
|---|---|---|---|
| Observational | Watching children play in a playground. | Realistic, natural setting. | Hard to control variables. |
| Experimental | Testing memory after caffeine vs. no caffeine. | Can infer causation. | Artificial lab conditions. |
| Correlational | Survey linking sleep hours to exam scores. | Large sample sizes possible. | No causal inference. |
| Case Study | In-depth study of a single autistic individual. | Rich, detailed data. | Not generalisable. |
| Survey | Online questionnaire on social media use. | Fast, cost‑effective. | Self‑report bias. |
Ethics in Research ⚖️
Psychologists must protect participants. Key principles:
- Informed consent: participants know what they’re doing.
- Confidentiality: keep data private.
- Minimise harm: avoid distress or injury.
- Debriefing: explain the study after participation.
Exam Tips & Tricks 📚
Tip 1: When asked “Why do psychologists conduct research?”, start with the purpose (e.g., to test hypotheses, improve practice) and then give examples.
Tip 2: Use the word “method” to show you understand how evidence is gathered.
Tip 3: For short answer questions, structure your answer with purpose → method → outcome → implication.
Tip 4: Remember the “ethical checklist” – consent, confidentiality, minimising harm, debriefing.
Practice Question: Explain why a psychologist would choose an experimental design over a correlational design to study the effect of sleep on memory.
Answer guide: Experimental design allows control of variables and can establish causation, whereas correlational design only shows association.
Analogy Corner 🚀
Think of research as a cooking recipe:
- Ingredients = data.
- Recipe = research method.
- Cooking time = data collection.
- Tasting = data analysis.
- Serving = publishing results.
Just as a chef follows a recipe to create a dish, psychologists follow a method to produce reliable knowledge.
