The Birth of Psychology
Psychology, as a scientific discipline, emerged in December 1879 at the University of Leipzig,
Germany. Wilhelm Wundt established the first psychological laboratory, aiming to measure basic
mental processes. His early experiments involved measuring the time it took for individuals to
react to stimuli, like pressing a telegraph key after hearing a ball drop. Wundt sought to
understand the "atoms of the mind" – the simplest mental processes.
Early Schools of Thought
From this new science of psychology, several schools of thought developed:
Structuralism
Key Figures: Wilhelm Wundt, Edward Bradford Titchener
Goal: To classify and understand the basic elements of the human mind's structure.
Method: Introspection, where individuals were trained to report their immediate sensations,
images, and feelings in response to stimuli (e.g., looking at a rose, hearing a metronome).
Decline: Structuralism faded as introspection proved unreliable and difficult to standardize,
akin to understanding a car by examining each part in isolation.
Functionalism
Key Figures: William James (influenced by Charles Darwin)
Goal: To understand the functions of mental processes and behaviors, and how they enable
organisms to adapt, survive, and thrive.
Core Idea: Influenced by evolutionary theory, James proposed that thinking, like other
biological functions, evolved because it served an adaptive purpose, helping ancestors
survive and reproduce.
Focus: Investigated the adaptive functions of consciousness, emotions, memories, willpower,
habits, and the continuous flow of thoughts.
Key Publication: William James authored "Principles of Psychology" in 1890.
Notable Figure: Mary Whiton Calkins, a student of James, pioneered memory research and
was the first woman to preside over the American Psychological Association.
Evolving Definitions of Psychology
Early Definition (Wundt, Titchener, James): "The science of mental life." This definition
focused on internal experiences like sensations, feelings, and the flow of consciousness.
