Intro to Psychology: Origins, Key Figures, and Early Schools (Transcript Notes)

Overview

Psychology is introduced as the study of the brain’s incredible complexity and how it enables consciousness, behavior, and social function.
The mind is described as the most complicated thing excluding other minds, with its rules being mysterious and elusive.
The course aims to explore how brains work, how they can fail, heal, and why people behave the way they do, including questions about consciousness, self, and free will.

Etymology and Scope

The word psychology comes from the Latin for the study of the soul.
Today’s definition: the science of behavior and mental processes.
The term was coined around the turn of the 16th century; formal science-as-we-know-it emerged in the mid-1800s (mid-1800s).
The course’s framing borrows from Crash Course’s exploration of these topics.

Historical Context and Early Questions

Ancient root ideas: Aristotle believed the seed of consciousness resided in the heart, which is noted as being wrong in hindsight.
Early global efforts: Two thousand years ago, Chinese rulers conducted the world’s first psychological exams requiring public officials to take personality and intelligence tests.
In the late 800s (late 800s), Persian physician Razis (Mohammed Ibn Zakaria al-Razi) described mental illness and ran a very early psych ward in Baghdad.
Core questions then and now include: how can humans commit horrible acts and how do we judge them as horrible? Do we have free will, or are we driven by environment, biology, and nonconscious influences?
Central topics for the upcoming study period: what is mental illness, what can we do about it, what is consciousness/self, and whether losing awareness means losing humanity.
Over the next six months, the course will cover how brains work, how they break, how they heal, why we behave as we do even when we don’t want to, and what it means to think, feel, and be alive.

Course Imagery and Stereotypes

A common stereotype of psychology is a therapist listening to a patient on a couch, possibly pictured with glasses, a cigar, and a whiskered chin.
Freud is a frequent cognitive shorthand for psychology in popular culture, though he is just one influential and controversial figure among many.

Sigmund Freud and His Legacy

Freud was tremendously influential and controversial, shaping ideas about childhood, personality, dreams, and sexuality.
His work spurred both strong support and opposition.
Freud’s life spanned a broad historical period, from the American Civil War era to World War II.
Like many scientists, Freud built on the work of others, rather than inventing ideas in isolation.

The Diversity of Psychology

Psychology is described as a wildly diverse science in terms of questions, methods, and schools of thought.
It is portrayed as an integrated melting pot of ideas and disciplines.
Around Freud’s era, several schools debated how to study the mind, notably structuralism, functionalism, and psychoanalysis.
This diversity points to a field that blends biology, philosophy, and social science approaches to understanding mind and behavior.

The Birth of Scientific Psychology

Scientific psychology began in 1879 in Germany when physician Wilhelm Wundt set up the first psychology laboratory at the University of Leipzig.
Shortly after, he published what is considered the first true psychology textbook, the Principles of Physiological Psychology.
Wundt and his student Edward Bradford Titchener drew inspiration from chemists and physicists, arguing that if matter could be broken down into simple elements, perhaps the brain could be broken down similarly.

Structuralism and Introspection

Structuralism aimed to understand the structures of consciousness by breaking experiences down into their components.
The method relied heavily on introspection—asking patients how they felt during experiences (e.g., sunsets, smells, or even licking a kitten).
The approach was named by Kitchener (as per the transcript) as structuralism.
A major drawback of this method was its subjectivity: two people can experience the same stimulus differently, making consistent, objective science challenging.
The transcription notes illustrate the introspective example: asking someone how they felt when they watched a sunset, smelled coffee, or licked a kitten, highlighting the subjective nature of inner experiences.

Functionalism, Psychoanalysis, and the Expansion of the Field

While not elaborated in depth in this segment, the transcript references the presence of multiple schools (structuralism, functionalism, psychoanalysis) during Freud’s era, signaling a broader movement beyond early structuralism.
The field is described as an integrated melting pot where different approaches coexist and compete to explain behavior and mental processes.

Key Concepts and Definitions (Recap)

Psychology: the science of behavior and mental processes.
Structuralism: an early school focusing on the structure of conscious experience via introspection.
Introspection: self-examination of inner thoughts, feelings, and sensations as a method of study.
Psychoanalysis: Freud’s broader school focusing on unconscious processes, childhood experiences, and their influence on behavior (not deeply elaborated here but referenced as part of the era’s diversity).
Consciousness: a core topic of inquiry, including what it means to be aware of oneself.
Self: related to consciousness and personal identity; questions about what remains when self-awareness is altered or lost.

Connections, Relevance, and Implications

The evolution of psychology from philosophical questions about the soul to empirical science reflects a shift toward observable behavior and mental processes.
The historical interplay between science, culture, and ethics is evident in questions about free will, moral responsibility, and the treatment of mental illness.
The “melting pot” nature of the field suggests ongoing dialogue among competing theories and methods, with modern psychology integrating biology, cognitive science, clinical practice, and social science.

Practical and Ethical Implications (Implied in the Transcript)

Understanding the roots of mental illness informs how we diagnose and treat psychological disorders.
Debates about free will vs. determinism have philosophical and practical implications for responsibility and therapy.
The subjective nature of introspection highlights the need for rigorous, diverse methodologies in psychology to achieve reliable knowledge.
