What is the definition of psychology?

The definition of psychology as the scientific study of the mind and behavior encapsulates the broad scope of the field. Psychology not only examines mental processes, such as thoughts and emotions, but also behaviors and how they are influenced by a variety of factors, including biological, social, and environmental aspects.

This definition emphasizes the scientific nature of psychology, which involves systematic observation, experimentation, and analysis to draw conclusions about mental functions and behaviors. By describing psychology as a scientific study, it distinguishes the discipline from mere speculation or philosophy, highlighting its reliance on empirical evidence and research methodologies.

The other options focus on narrower aspects of psychology. For instance, emotional study or exploration of unconscious thoughts represents only part of the field, while the analysis of social interactions might pertain to social psychology specifically. Thus, the comprehensive definition captures the full range of inquiry that psychology entails.
