What is psychological theory

You may wonder why there are so many different psychology approaches and whether one approach is correct and others wrong. Most psychologists would agree that no one approach is correct, although in the past, in the early days of psychology, the behaviorist would have said their perspective was the only truly scientific one. Each approach has its strengths and weaknesses, and brings something different to our understanding of human behavior.  For this reason, it is important that psychology does have different perspectives on the understanding and study of human and animal behavior.
