FAQs on Psychology's Scientific Method Video Lecture - Psychology for UPSC Optional (Notes)

1. What is the scientific method in psychology?
Ans. The scientific method in psychology is a systematic approach used by psychologists to investigate phenomena, acquire new knowledge, or correct and integrate previous knowledge. It involves several steps: formulating a hypothesis, conducting empirical research, collecting data, analyzing results, and drawing conclusions. This method ensures that findings are based on observable and measurable evidence, making them more reliable and valid.
2. How does the scientific method enhance the credibility of psychological research?
Ans. The scientific method enhances the credibility of psychological research by promoting objectivity and minimizing bias. By relying on systematic observation and experimentation, psychologists can ensure that their findings are consistent and replicable. This rigorous process allows for peer review and verification, which strengthens the trustworthiness of the research findings, making them more accepted in the scientific community.
3. What are some common research methods used in psychological studies?
Ans. Common research methods in psychology include experiments, observational studies, surveys, and case studies. Experiments allow researchers to establish cause-and-effect relationships by manipulating variables. Observational studies involve watching subjects in their natural environments without interference. Surveys collect data from large groups through questionnaires, while case studies provide an in-depth look at a particular individual or group, often used for rare phenomena.
4. Why is hypothesis testing important in psychological research?
Ans. Hypothesis testing is crucial in psychological research because it provides a framework for making predictions and determining the validity of those predictions based on empirical evidence. By establishing a null hypothesis (which states there is no effect) and an alternative hypothesis (which states there is an effect), researchers can use statistical methods to analyze data and draw conclusions. This process helps in confirming or refuting theories and contributes to the advancement of psychological knowledge.
5. What role do ethics play in psychological research using the scientific method?
Ans. Ethics play a vital role in psychological research as they ensure the protection of participants' rights and well-being. Ethical guidelines require researchers to obtain informed consent, ensure confidentiality, and minimize harm. Researchers must also debrief participants after the study to explain its purpose and findings. Adhering to ethical standards not only fosters trust between researchers and participants but also enhances the integrity of the research process, allowing for responsible advancements in psychology.
