What are the two main components of the scientific method in psychology?

The two main components of the scientific method in psychology are observation and experimentation. Observation involves collecting data and evidence through various means, such as surveys, case studies, or behavioral assessments, which allows psychologists to identify patterns and generate hypotheses.

Experimentation is the process of testing these hypotheses in controlled environments to determine cause-and-effect relationships. By manipulating variables and observing the outcomes, psychologists can draw conclusions that are supported by empirical evidence. This systematic approach ensures that psychological research is grounded in observable phenomena rather than subjective opinions or beliefs, thus aligning with the principles of the scientific method.

The other options incorporate elements relevant to psychology but do not encapsulate the primary components as effectively. Introspection involves examining one's own conscious thoughts and feelings, which provides valuable insights but is more subjective and less systematic than observation. Hypothesis and experimentation are indeed crucial, but a hypothesis alone does not encompass the observation aspect necessary for data collection before testing. Lastly, while theory and application are significant aspects of psychology, they do not represent the core methodological components involved in conducting scientific research in the field.
