Types of Psychology

Psychology is a broad and diverse field that encompasses the study of human thought, behavior, development, personality, emotion, motivation, and more. As a result, some different subfields andspecialty areashave emerged. The following are some of the major areas of research and application within psychology:

• Abnormal psychologyis the study of abnormal behavior and psychopathology. This specialty area is focused on research and treatment of a variety of mental disorders and is linked to psychotherapy and clinical psychology.
• Biological psychology(biopsychology) studies how biological processes influence the mind and behavior. This area is closely linked to neuroscience and utilizes tools such as MRI and PET scans to look at brain injury or brain abnormalities.
• Clinical psychologyis focused on the assessment, diagnosis, and treatment of mental disorders.

• Developing educational programs
• Ergonomics
• Informing public policy

Impact of Psychology

Psychology is both an applied and academic field that benefits both individuals and society as a whole. A large part of psychology is devoted to the diagnosis and treatment of mental health issues, but that's just the tip of the iceberg when it comes to the impact of psychology.

Some of the ways that psychology contributes to individuals and society include:

• Improving our understanding of why people behave as they do as well
• Understanding the different factors that can impact the human mind and behavior
• Understanding issues that impact health, daily life, and well-being
• Improving ergonomics to improve product design
• 创造更安全、更高效的工作空间
• Helping motivate people to achieve their goals
• Improving productivity

Psychologists accomplish these things by usingobjective scientific methodsto understand, explain, and predict human behavior. Psychological studies are highly structured, beginning with ahypothesisthat is then empirically tested.

Potential Pitfalls

There's a lot of confusion out there about psychology. Unfortunately, suchmisconceptions about psychologyabound in part thanks to stereotyped portrayals of psychologists in popular media as well as thediverse career pathsof those holding psychology degrees.

Sure, there are psychologists who help solve crimes, and there are plenty of professionals who help people deal with mental health issues. However, there are also psychologists who:

• Contribute to creating healthier workplaces
• Design and implement public health programs
• Research airplane safety
• 帮助设计技术和计算机程序
• Study military life and the psychological impact of combat

No matter where psychologists work, their primary goals are to help describe, explain, predict, and influence human behavior.

History of Psychology

Early psychology evolved out of both philosophy and biology. Discussions of these two subjects date as far back as the early Greek thinkers, including Aristotle and Socrates.

The emergence of psychology as a separate and independent field of study truly came about whenWilhelm Wundtestablished thefirst experimental psychology labin Leipzig, Germany in 1879.

Throughout psychology's history, variousschools of thoughthave formed to explain the human mind and behavior. In some cases, certain schools of thought rose to dominate the field of psychology for a period of time.

The following are some of the major schools of thought in psychology.

• Structuralism: Wundt and Titchener'sstructuralismwas the earliest school of thought, but others soon began to emerge.
• 功能ionalism: The early psychologist and philosopher William James became associated with a school of thought known as functionalism, which focused its attention on the purpose ofhuman consciousnessand behavior.
• Psychoanalysis: Soon, these initial schools of thought gave way to several dominant and influential approaches to psychology. Sigmund Freud'spsychoanalysiscentered on how the unconscious mind impacted human behavior.
• Behaviorism: Thebehavioral school of thoughtturned away from looking at internal influences on behavior and sought to make psychology the study of observable behaviors.
• Humanistic psychology:Later, thehumanistic approachcentered on the importance of personal growth and self-actualization.
• Cognitive psychology: By the 1960s and 1970s, thecognitive revolutionspurred the investigation of internal mental processes such as thinking, decision-making, language development, and memory.

While these schools of thought are sometimes perceived as competing forces, eachperspectivehas contributed to our understanding of psychology.

A Word From Verywell

As you can see, while psychology may be a relatively young science it also has a tremendous amount of both depth and breadth. The assessment, diagnosis, and treatment of mental illness are central interests of psychology, but psychology encompasses much more than mental health.

Today, psychologists seek to understand many different aspects of the human mind and behavior, adding new knowledge to our understanding of how people think as well as developing practical applications that have an important impact on everyday human lives.
