What do all areas of psychology have in common

Each branch or field looks at questions and problems from a different perspective. While each has its own focus on psychological problems or concerns, all areas share a common goal of studying and explaining human thought and behavior.

The areas of psychology fall into place because, regardless of their focus of study, they all aim to understand the human mind and behavior and help mentally sick people learn to cope and to live better.

Explanation:

Psychology seeks to describe sensations, emotions, thoughts, perceptions, and other motivating states of human behavior.
