Historical Background:
- Origin of the Term:
  - Psyche (soul) + Logos (study) = Psychology (study of the mind).
  - The term emerged in the 16th century; gained prominence in the 18th century.
- 150 Years Ago: Psychology transitioned from philosophical speculation to a scientific discipline.

Intellectual Roots:
- Psychology emerged from philosophy and physiology during the 1870s.
- Questions explored include interaction between bodily sensations and mental awareness.
Wilhelm Wundt (1832-1920):
- Founded the first psychological research laboratory at Leipzig in 1879, marking psychology's 'birth'.
- Wundt advocated for psychology as a science focused on consciousness and immediate experience.
Impact of Wundt:
- Established the first journal for psychology research, leading to the formation of labs worldwide.
- Significant growth in North America, with approximately 23 new labs between 1883-1893.

Competing Schools of Thought:
- Structuralism:
  - Led by Edward Titchener.
  - Aimed to analyze consciousness into basic elements using introspection.
  - Focused on elements like sensations, feelings, and images.
- Functionalism:
  - Influenced by William James, opposing the static nature of structuralism.
  - Emphasized the continuous flow of consciousness, termed "stream of consciousness".
  - Explored adaptation and real-world behaviors, expanding topics into mental testing and educational practices.
Legacy of the Two Schools:
- Functionalism laid the groundwork for behaviorism and applied psychology.

Sigmund Freud (1856-1939):
- Founded psychoanalysis derived from efforts to treat mental disorders.
- Introduced the concept of the unconscious, asserting it influences behavior.
- Stressed the role of unconscious conflicts and sexual urges, igniting debates in psychology.

John B. Watson:
- Revolutionized psychology, asserting that it should study only observable behavior.
- Pioneered behaviorism as a scientific method relying on verifiability.
- Advocated environmental factors over heredity, claiming behavior is shaped solely by experience.

B.F. Skinner:
- Expanded behaviorism by highlighting environmental control over behavior.
- Conducted experiments on reinforcement, explaining behaviors within established environments.
- Controversially suggested that free will is an illusion due to environmental control.

Emergence of Humanism:
- Opposed behaviorism and psychoanalysis, emphasizing human freedom and potential for growth.
- Key figures include Carl Rogers and Abraham Maslow, who focused on self-concept and personal development.

Clinical Psychology:
- Initially emphasized psychological testing; expanded in post-WWII era to address veteran mental health needs.
- Growth led to broader application specialties in psychology covering counseling and education.

Cognitive Psychology:
- Revived interest in studying mental processes, aided by advances in information technology.
- Cognitive theorists advocate for understanding internal mental events.

Emergence of Evolutionary Psychology:
- Focuses on behavior as adaptive through natural selection, similar to anatomical traits.
- Became noteworthy in the late 1980s with research highlighting mating preferences and aggression.

Martin Seligman's Initiative:
- Launched a movement focused on positive aspects like happiness and personal growth, shifting focus away from pathology.
- Established three areas of interest: subjective experiences, individual traits, and positive institutions.

Definition of Modern Psychology:
- A dynamic field studying behavior, cognition, emotions, and the physiological processes behind them.
- Notable growth in numbers of professionals and research areas, enriching the field of psychology.
