What is the focus of the science known as psychology?

Psychology is primarily focused on understanding human behavior, which includes the thoughts, emotions, and actions that individuals exhibit. This discipline explores various aspects of human experience, including how people think, how they interact with others, and how they respond to their environment. By studying behavior, psychologists aim to uncover patterns and underlying mechanisms that can help explain why individuals act the way they do, both individually and socially.

In contrast, other disciplines like anatomy deal specifically with the structural aspects of the human body, while the study of medical disorders focuses on various diseases and health conditions. The examination of environmental impacts on health belongs to fields like public health and environmental science, which concentrate on external factors affecting well-being. Thus, psychology distinctly centers on the complexities of human behavior, making it the accurate focus within the context of the question.
