What are the main types of research methods in psychology and what are their advantages and disadvantages? (6 marks) The main types of research methods in psychology are experiments, correlational studies, surveys, naturalistic observations and case studies. Experiments involve manipulating an independent variable and measuring its effect on a dependent variable while controlling other variables. Experiments can establish cause-and-effect relationships but may lack ecological validity. Correlational studies involve measuring the relationship between two or more variables without manipulating them. Correlational studies can reveal patterns and associations but cannot establish causality. Surveys involve asking a sample of people questions about their attitudes, opinions or behaviors. Surveys can collect large amounts of data quickly and cheaply but may suffer from sampling bias, social desirability bias or low response rates. Naturalistic observations involve observing and recording behavior in its natural setting without interfering with it. Naturalistic observations can provide rich and realistic data but may be affected by observer bias, reactivity or ethical issues. Case studies involve studying an individual or a small group in depth over a period of time. Case studies can provide detailed and unique insights but may not be generalizable or representative.
