Note a couple of important movements in psychology's history in the United States particularly
- Modern science arose in the first half of the 19th century. What we call "Science" was originally called "Natural Philosophy." As the 19th century progressed, sciences such as chemistry, physics, biology, and physiology became distinctive areas of research.
- Modern psychology was born in the second half of the 19th century. The establishment of an experimental lab by Wilhelm Wundt at the University of Leipzig (Germany) in 1879 is often cited as the beginning, certainly, of psychology as an experimental science
- For the first half of the 20th century, there were a set of major competing "schools of thought." Various psychologists theorized what the basic functions of the mind and thinking were about. The competition among these schools tended to die out by 1950 as other approaches to psychology took hold.
- Between 1900 and 1939, Sigmund Freud argued that our unconscious is primarily responsible for what we do. And, so, he questioned whether we even have "free will". His "psychoanalytic theory" of unconscious motivation for behavior was very influential in the United States until the late 1970s.
- But, J. B. Watson, B. F. Skinner, and other "behaviorists" denied Freud's claim and said we should only look at external behaviors (not at the mind). Both Watson and Skinner were inheritors of the work of the late 19th century Russian physiologist, Ivan Pavlov
- After the 2nd World War, beginning in the 1950, the "Humanists" emerged to champion free will and the unique qualities of each human person. Toward the end of the 20th century, "positive psychology" emerged to advance the notion that people have strengths and resources that they can use to deal with life in successful ways.
- As we moved to the last part of the 20th century, psychologists became more interested in neuroscience and the biological influences on behavior and on "evolutionary" forces that emerge from our genetic make-up as we interact with the environment.

What do psychologists do?
"Psychologists study cognitive, emotional, and social processes and behavior by observing, interpreting, and recording how people relate to one another and their environments."Median Pay (2024) median = half higher, half lower
Types of Psychologists
- Clinical Psychologists "assess, diagnose, and treat mental, emotional, and behavioral disorders"
- Health Psychologists
- Neuropsychologists
- Counseling Psychologists "help patients deal with and understand problems, including issues at home, at the workplace, or in their community."
- Developmental Psychologists "study the psychological progress and development that take place throughout life"
- Forensic Psychologists "use psychological principles in the legal and criminal justice system to help judges, attorneys, and other legal specialists understand the psychological aspects of a particular case."
- Industrial-Organizational Psychologists [Organizational Behavior Psychologists] "apply psychology to the workplace by using psychological principles and research methods to solve problems and improve the quality of work life. They study issues such as workplace productivity, management or employee working styles, and employee morale"
- School Psychologists "apply psychological principles and techniques to education and developmental disorders"
- Social Psychologists "study how people’s mindsets and behavior are shaped by social interactions."
- Psychologists also become university, college, and high school teachers

Work Environments
Some psychologists work independently, conducting research, consulting with clients, or working with patients. Others work as part of a healthcare team, collaborating with physicians and social workers or in school settings, working with students, teachers, parents, and other educators. Those in private practice often work evenings and weekends to accommodate clients.
What primary types of jobs do people hold with different degrees in psychology?
- There are significant differences across job areas depending upon whether you have a bachelor's or higher level of degree.
- Almost half of Master's and doctoral level psychologists are involved in providing clinical, counseling, health, and other services to clients and patients.
- Many doctoral-level psychologists, such as me, are involved in teaching at the college/university level (18%) and an almost identical percent are mostly involved in doing research as their primary work (15%).
How to Become A Psychologist
Although psychologists typically need a doctoral degree in psychology, a master’s degree is sufficient for some positions, particularly when working in schools, hospitals, or similarly licensed facilities. Psychologists in independent practice almost always need to be licensed by the state in which they live.
Seven Unifying Themes in our Psychology Textbook (pp. 20-23)
Psychology as a Field of Study
- Is there such a thing as Extrasensory Perception (ESP)?
- Why don't psychologists believe that ESP exists?
- Psychologists are skeptical and want to see evidence
- Extraordinary claims require extraordinary evidence
- If you were to believe in alien abduction by UFOs or our lives are controlled by the position of the planets and stars (astrology), you should be able to provide overwhelming evidence to prove it.
- Color vision: Trichromatic vs. Opponent-Process theories are BOTH correct
- Multiple theories in psychology ("theory" = system of interrelated ideas to explain a set of observations)
- The need for multiple theories probably rests on the extraordinary complexity of what psychology seeks to explain
Biology, chemistry, and physics generally deal with either non-life forms or life forms which have far less complex nervous systems than humans.
- Human beings as the single most complex reality in the universe other than the universe itself
- Brain contains almost 1010 neurons (ca. 86,000,000,000, i.e., 86 billion) and 1014 (100 trillion) connections.
- 55 cubic millimeters (3.8 mm on a side) of brain tissue contains about 5.5 million neurons, 22 to 55 billion synapses, 22 kilometers of dendrites and 220 kilometers of axons (Logothetis, 2008, p. 875)
- Are women inferior to men in their thinking?
- Are Europeans more intelligent than Africans?
- Are Asians more intelligent than Europeans?
- Psychology both reflects its own cultural background and shapes that background
- Reflects: Freud's ideas on sexuality stemming from sexual repression of Victorian Era
- Shapes: Scientific testing of intelligence, abilities, achievement & personality fill schools, businesses, & health care
- Our own desire to improve educational progress of children will prompt us to seek ways of helping them.
