19 Different Types of Jobs in Psychology (Career Opportunities)

A man at psychologists appointment communication, diagnosis of the problem, consultation.

William James, known as the Father of American Psychology, described the field as the “science of mental life”. This apt and concise description has not been surpassed. Psychologists study the inner workings, functions, and effects of thought processes, emotions, memories, dreams, perceptions, sensations, and other cognitive occurrences and the behaviors associated with them.

The field should not be confused with either neuroscience, which is the study of the brain, or psychotherapy, which is a specialized form of psychology.

What Does Psychology Encompass?

Psychologists have many roles in private practice and in institutions. They use a variety of tools to carry out assessments, analyze their findings, and write up reports or recommend solutions. Psychologists do everything from carrying out studies for health authorities to assessing children who may find it difficult to learn in school to helping companies recruit, select, and train employees.

The most important thing to understand is that psychologists are trained scientists. Obtain a degree in psychology requires mastery of quantitative and qualitative research methods. Although there are psychologists who work primarily as researchers, all psychologists, no matter their particular role, are guided by fact and evidence.

A Brief History of Psychology

The study of mental life goes back thousands of years ago to ancient Greece, Egypt, India, Persia, and China. The more recognizable forms of it can be detected in the Greek philosophers Plato and Aristotle. These two disagreed on where mental processes take place.

Plato believed it was in the brain. His student Aristotle believed it was the heart. The former was, of course right. However, even the Greek Atomists, who preceded both these philosophers, speculated on the source and central location of human thought and feeling.

Like Aristotle, they believed it was the heart. The Greek physician Galen, who lived in 2nd century Turkey, posited that human beings were composed of four humours. This was the first attempt at describing personality traits and developing a larger theory of human personality.

Avicenna, a 10th century Muslim doctor, studied and treated epilepsy, nightmares, and poor memory. Indeed, the first hospitals dedicated to the treatment of psychiatric conditions were established by Medieval Muslim doctors. Modern psychology got its start with Hermann von Helmholz’s studies in human vision and hearing in the 1850s.

This provided the foundation for the work of Wilhelm Wundt, who established psychology as an independent experimental field of study in Germany in 1879. In 1890, the American psychologist, who had already established the first psychological laboratory in the U.S., published the Principles of Psychology.

The book became the standard textbook for psychological studies on both sides of the Atlantic for the next three decades. James was one of the few American scientists fluent in both French and German, which at the time was where the most advanced work in psychology was pursued. He was therefore able to bring together and synthesize all the scholarship in the field and convey the major problems, theories, and ideas in this new science.

1890 was also the year that the American Psychological Association (APA) was founded. In the early 20th century, the Austrian Sigmund Freud introduced psychoanalysis into the field as a new and innovative type of psychotherapy. Freud used interpretive methods, introspection, and clinical observation—in short, a talking cure—to help patients resolve unconscious conflict, mental distress, and psychopathology.

Freud’s theories revolutionized the field of psychotherapy. No form of therapy since Freud has been left untouched by his writings. In 1913, the American psychologist John B. Watson founded a new movement in the field called behaviorism.

He argued that behavior is the result not of internal mental processes but of how people respond to their environment. In the middle of the century, the humanist movement gained grown. Humanist psychologists believed that both behaviorism and psychoanalysis were too dehumanizing.

They stressed the value of emotions, free will, and subjective experience in understanding mental life. Cognitive theory came to the fore in the 1970s. In a way, it harkened back to the early days of psychology, with its focus on how the mind organizes, manipulates, remembers, and relates ideas, concepts, and information.

Advances in technology and methods have allowed the adherents of cognitive theory to explore areas and make discoveries that were not possible in the 19th century. Cognitive theory is applied to language, learning, perceptual systems, mental disorders, and dreams. Today, all of the above theories and movements are still in use.

Psychologists choose the approach that is most suitable for each situation.
