• Experiments: A research method involving manipulating one or more independent variables to observe their effect on one or more dependent variables, while controlling other variables.
• Observations: Involves systematically watching and recording behavior, either in natural settings or in laboratory environments.
• Surveys: Gathering data from a large pool of people through questionnaires or interviews to understand attitudes, beliefs, or behaviors.

• Debriefing participants about the research procedures at the end to share results in a manner that aligns to responsible research practices.
• Adhering to established codes of ethics for psychological research, maintaining the integrity of research.
