Introduction to Psychology

Psychology is characterized as a relatively young science with experimental roots dated back to the 19th century.
- Compared to other fields such as human physiology, which has earlier origins.
- Prior to the 19th century, studies of the mind were conducted in a philosophical context.

Wilhelm Wundt and William James are credited as the founders of psychology as a science and distinct academic discipline.

Wilhelm Wundt (1832–1920)
- First person referred to as a psychologist.
- Authored "Principles of Physiological Psychology" published in 1873.
- Defined psychology as a scientific study of conscious experience.
- Aimed to identify components of consciousness and their combinations.
- Introduced introspection (or "internal perception"):
- A process where individuals examine their own conscious experiences objectively.
- Advocated for voluntarism:
- Belief in free will and the necessity for participants to know the intentions behind psychological experiments (Danziger, 1980).
- Conducted experimental introspections, measuring reaction times using various instruments.
- Established the first psychology laboratory at the University of Leipzig in 1879;
- Measured reaction times to stimuli with precision up to one-thousandth of a second.
- Published "Volkerpsychologie" in 1904, emphasizing the inclusion of cultural studies in psychology.
Edward Titchener (student of Wundt):
- Further developed structuralism focusing on the contents of mental processes rather than their functions (Pickren & Rutherford, 2010).

William James, John Dewey, and Charles Sanders Peirce
- Established functional psychology rooted in Darwin’s theory of evolution by natural selection.
- In functionalism:
- Emphasis on the function of behavior in adapting to the environment.
- Strives to understand how mental activities assist organisms in fitting into their surroundings.
- Utilization of introspection complemented with objective measures such as recording devices and physiological observations.

Sigmund Freud (1856–1939):
- Influential Austrian neurologist known for his work on hysteria and neuroscience.
- Developed the notion of the unconscious mind as a reservoir of feelings and urges outside of conscious awareness.
- Gaining access to the unconscious is regarded as crucial for resolving patient issues.
- Techniques to access the unconscious include:
- Dream analysis.
- Free association (the first words that come to mind).
- Slips of the tongue.
- His psychoanalytic theory emphasizes the role of the unconscious and early childhood experiences in shaping behavior (Thorne & Henley, 2005).
- Despite the controversies surrounding Freud, many therapists incorporate aspects of his theories today.

Max Wertheimer, Kurt Koffka, and Wolfgang Köhler:
- Introduced Gestalt principles that focus on perception as a whole rather than the sum of parts.
- Gestalt translates to “the form in its whole.”
- They assert that sensory experiences are best understood through their relationships and configurations.
- Contrasted with Wundt's structuralism views.
- Immigrated to the U.S. to escape Nazi Germany but faced challenges in conducting large-scale research.

John B. Watson (1878–1958):
- Major American psychologist who shifted focus from mind to behavior due to perceived flaws in studying consciousness.
- Advocated for behaviorism, which emphasizes observable behaviors and their interactions with learned experiences.
- Supported the idea that animal behavior studies can be applied to human behavior.
Ivan Pavlov (1849–1936):
- Russian physiologist who researched classical conditioning, demonstrating how reflex behaviors could be conditioned through association.
- Example: Dogs salivating at a sound associated with food.
B.F. Skinner (1904–1990):
- An American behaviorist focusing on how behavior is shaped by reinforcement and punishment.
- Developed the operant conditioning chamber (Skinner box), a device to study behavior modification.
- Used for reinforcing behaviors with rewards or introducing punishments.

Emerged as a reaction to behaviorism and psychoanalysis due to dissatisfaction with existing perspectives in psychology.
Emphasizes:
- Personal control and intentionality.
- The inherent positivity and growth potential in all humans.

Abraham Maslow (1908–1970):
- Known for proposing a hierarchy of needs motivating behavior related to self-actualization.
- Hierarchy of needs is presented as a stage-model where basic needs must be met before higher needs can motivate behavior.
Carl Rogers (1902–1987):
- Developed client-centered therapy, placing the patient in a leading role during therapy sessions.
- Identified three key therapist qualities for effective therapy:
- Unconditional positive regard: Accepting the client without judgment.
- Genuineness: Authenticity of the therapist.
- Empathy: Understanding the client’s perspective and experiences.

Critiques addressed inherent biases within psychology's early development led predominantly by Western, White, and male academics.
Naomi Weisstein’s work (1968) critiqued the construction of psychology, particularly regarding female experiences.
- Argued for the recognition and inclusion of women’s perspectives in psychological research.

Culture significantly impacts individuals and society. Over-researched populations often yield flawed generalizations.
The term WEIRD (Western, Educated, Industrialized, Rich, and Democratic) characterizes over-studied societies, prompting calls for better representation in psychological research.

Francis Cecil Sumner: First African American to earn a Ph.D. in psychology; established a psychology program at Howard University.
Research by George I. Sanchez on language barriers in intelligence testing for Mexican American children highlighted cultural limitations.
Mamie Phipps Clark and Kenneth Clark: Their research on children's preference for dolls influenced the landmark Brown v. Board of Education case.
