Which statement best defines a theory in psychology?

A theory in psychology is best defined as a comprehensive explanation of behaviors. This means that a theory integrates various observations and findings, providing a broad understanding of psychological phenomena. It usually encompasses multiple hypotheses and has been supported by extensive empirical research. Theories aim to explain and predict complex behaviors and mental processes, making them foundational in the field of psychology.

In contrast, a set of unrelated hypotheses does not form a coherent explanation, as theories are built upon interconnected ideas that are supported by research. A hypothesis lacking empirical support does not meet the criteria for a theory, which must be substantiated by data. Additionally, a simple observation made during an experiment, while useful for generating questions or hypotheses, does not provide the depth and encompassing nature required to qualify as a theory. Hence, the definition of a theory as a comprehensive explanation of behaviors captures its essence within psychology effectively.
