INTRODUCTION TO PSYCHOLOGY

had a dream about a dinosaur wearing a leotard? Or maybe you've said something that you later realized was totally inappropriate? Our minds are amazing, constantly working to keep us going and make society function smoothly. We're grateful for all the things we can do, but sometimes we wish we could stop doing certain things. Did you know that your mind is the most complex thing in the universe (besides other humans' minds, of course)? It's so complex that we still don't fully understand how it works. But that won't stop us from trying to figure it out! Did you know that the word 'psychology' originally came from the Latin word for "study of the soul"? Pretty cool, right? Nowadays, we define psychology as the science of behavior and mental processes. It's interesting to note that the term 'psychology' wasn't even coined until the 16th century, and it wasn't until the mid-1800s that it became the science we know today. But let's be real, humans have always been curious about themselves and what makes us tick. Even Aristotle pondered the seed of human consciousness, but he was totally wrong when he thought it was in the heart instead of the head. We've come a long way since then! Two millennia ago, Chinese rulers pioneered the administration of the world's inaugural psychological examinations, mandating that public officials undergo personality and intelligence assessments. Similarly, in the late 800s, the Persian physician Muhammad ibn Zakariya al-Rhazes, renowned as Rhazes, emerged as one of the earliest individuals to elucidate mental illness. Notably, he even provided treatment to patients within a rudimentary psychiatric ward at his Baghdad hospital. Since the endeavors of these early intellectuals, the discipline of psychology has been dedicated to grappling with profound inquiries. These include understanding the capacity of humans to perpetrate abhorrent acts such as genocide and torture, as well as comprehending our innate awareness of the moral reprehensibility of such actions. Furthermore, psychology seeks to explore the extent of our autonomy, questioning whether our behavior is solely driven by environmental, biological, and subconscious influences or if we possess free will. Additionally, the field aims to define mental illness and develop effective interventions. Moreover, it endeavors to unravel the enigmatic nature of consciousness and the concept of self. If one were to lose self-awareness, does their humanity persist? These are the profound questions that lie ahead. Over the course of the next six months, we will embark on a collective exploration of how our brains function, how they can malfunction, how they can be restored, why our behavior sometimes contradicts our intentions, and the essence of cognition, emotion, and vitality. [Intro] When the term psychology is mentioned, the majority of individuals likely conjure an image of a therapist attentively listening to a patient as they divulge the intricacies of their day, all while reclining on a couch. Perhaps this therapist is adorned with spectacles, engrossed in the act of chewing on a cigar, and gently stroking their bearded chin. It is undeniable! If one contemplates the realm of psychology, it is highly probable that Sigmund Freud comes to mind. Sigmund Freud was an immensely influential and contentious intellectual of his era, perhaps even of all eras. His theories have contributed significantly to our understanding of childhood, personality, dreams, and sexuality. However, his work has also generated a legacy of both endorsement and dissent. Spanning a significant period of history from the American Civil War to World War II, Freud's life was extensive. Nevertheless, akin to most eminent scientists, Freud's groundbreaking ideas were built upon the work of his predecessors, and the field of study continued to evolve beyond his contributions. In actuality, psychology is a highly diverse scientific field that encompasses a wide range of inquiries, methodologies, and various schools of thought and disciplines. It can be argued that psychology is an integrated melting pot of knowledge, surpassing any other scientific discipline in this regard. During the era of Freud, there existed numerous schools of thought that offered distinct approaches to the study of the human mind. Primarily, the concepts of structuralism, functionalism, and psychoanalysis were prevalent. The inception of scientific psychology can be traced back to 1879 in Germany, when physician Wilhelm Wundt established the first psychology laboratory at the University of Leipzig. This occurred shortly after the publication of his Principles of Physiological Psychology, which is widely regarded as the first authentic psychology textbook. Wundt and his disciple Edward Bradford Titchener drew inspiration from chemists and physicists and posited that if these professionals could deconstruct all matter into basic elements or structures, then the same could be done for the brain. An attempt was made to comprehend the intricacies of consciousness through the utilization of introspection, wherein patients were prompted to reflect upon their experiences when witnessing a sunset, perceiving the aroma of coffee, engaging with a kitten through licking, or any other relevant stimuli. This approach was coined as 'structuralism' by Titchener; however, despite its seemingly rigid nomenclature, it heavily relied on subjective introspection. It should be noted that individuals may perceive and experience these stimuli differently, even if they were to engage in the same act of licking a kitten. Given that psychologists are unable to directly observe a patient's inner thoughts or emotions, the structuralist school of thought ultimately had a relatively short lifespan. In contrast, the American physician and philosopher, William James, presented an alternative series of inquiries, centering on the rationale behind our cognitive processes, emotions, olfactory perceptions, and even our gustatory actions. Essentially, his emphasis was on comprehending the purpose and utility of human behavior. Termed as 'functionalism', this approach was rooted in Charles Darwin's notion that adaptive behaviors persist across the course of evolution. In 1890, James authored his seminal work, The Principles of Psychology, which established psychology as the scientific study of mental processes. Coincidentally, during this period, Sigmund Freud was beginning to make significant contributions to the field. Freud commenced his medical profession at a hospital in Vienna, but in 1886, he established his private practice, focusing on the treatment of nervous disorders. It was during this period that Freud observed his colleague, Josef Breuer, utilize a novel talking therapy to treat a patient named Anna O. Essentially, he allowed her to articulate her symptoms. As she continued to express herself and recall distressing memories, her symptoms gradually diminished. This marked a significant breakthrough that had a profound impact on Freud's perspective. Subsequently, Freud began encouraging his patients to freely discuss any thoughts that came to mind, a technique known as free association. This approach served as the foundation for his career and an entire branch of psychology. In 1900, he published his seminal work, "The Interpretation of Dreams," in which he introduced his psychoanalytic theory. While contemporary understanding often associates psychoanalysis with the patient lying on a couch, Freud's concept was far more intricate and groundbreaking. A fundamental tenet of psychoanalysis revolved around the notion that our personalities are molded by unconscious motives. Essentially, Freud postulated that we are deeply influenced by mental processes of which we remain oblivious. Although this concept may appear self-evident to us today, it is crucial to acknowledge that Freud's theory possessed a remarkable ingenuity for its time, particularly in the year 1900. The notion that our thoughts and actions could be propelled by forces unbeknownst to our conscious minds was exceedingly difficult to comprehend. It presented a level of abstraction and invisibility that paralleled the challenge of comprehending the concept of organisms evolving through natural selection. Consequently, this idea seemed irrational and perplexing. However, another significant aspect of Freud's theory was the notion that the unconscious, which is situated beneath the level of consciousness, could still be explored. Despite being unaware of its existence, one could gain insight into it through a therapeutic approach that employed techniques such as dream analysis, projection, and free association to uncover repressed emotions and achieve self-awareness. Essentially, Freud posited that mental disorders could be remedied through talk therapy and self-exploration, which represented a major breakthrough. Prior to this, individuals with mental illnesses were typically institutionalized and, at best, assigned menial tasks, while at worst, they were restrained to bed frames.

Following the publication of The Interpretations of Dreams, Freud proceeded to author over 20 additional books and numerous papers, often seen with his iconic cigar in hand. Despite his belief that smoking aided his thought process, it ultimately led to his development of jaw cancer. Despite undergoing at least thirty painful surgeries during the final sixteen years of his life, he persisted in his smoking habit. In the late 1930s, Austria was taken over by the Nazis, and Freud and his Jewish family narrowly escaped to England. By September 1939, the pain from his cancerous jaw became unbearable, and a physician friend assisted him in his suicide through a morphine injection. He was eighty-three years old. Regardless of one's personal opinions of Freud - and it is important to note that many individuals vehemently disagreed with his theories - his impact on the field of psychology was monumental. While competing theories in the nascent field of psychology either faded away or evolved into something else, psychoanalysis remains a significant concept and practice to this day. During the first half of the 20th century, a significant transformation occurred with the emergence of behaviorism as a prominent field of study. Esteemed scholars such as Ivan Pavlov, John B. Watson, and B. F. Skinner played pivotal roles in this development, concentrating their efforts on the examination of observable behavior. Skinner, in particular, is renowned for his experimentation with rats, pigeons, and infants, conditioning them to exhibit specific behaviors.

Concurrently, Freud's psychoanalysis and its various offshoots, collectively referred to as psychodynamic theories, were also a major influence during this period. These theories emphasized the significance of early experiences in shaping the unconscious mind and how this process impacts our thoughts, emotions, actions, and personalities. Skinner's publication of Behavior of Organisms coincided with Freud's relocation to England, marking the beginning of the behaviorism era, which remained in vogue until the 1960s. During the mid-20th century, additional significant influences emerged within the field of psychology. These include humanist psychology, cognitive science, and neuroscience, which will be further examined in this course. Humanist psychology emphasizes the cultivation of personal development, while cognitive science and neuroscience offer distinct perspectives on the study of the mind. The contemporary definition of psychology, which pertains to the examination of human behavior and cognitive processes, is a comprehensive synthesis that draws upon various theoretical frameworks. It acknowledges the significance of observing and documenting behavior, encompassing actions such as vocalizing, weeping, or mimicking the performance of a saxophone to an imaginary audience. Additionally, it acknowledges the importance of our cognitive processes, encompassing our thoughts, emotions, and beliefs, as we engage in these activities. It is crucial to emphasize that psychology is an interdisciplinary field, integrating diverse perspectives. While disagreements and discord may still arise, the fundamental essence of this discipline lies in the development of innovative approaches to pose intriguing inquiries and endeavoring to address them through a wide range of data collection methods. The human mind is a complex entity, for which there is no singular approach to fully comprehend it; rather, it necessitates a comprehensive examination from various perspectives. Owen Gingerich, an esteemed astronomer from Harvard University, has directed his gaze towards the vast expanse of space, yet he too acknowledges that the human brain surpasses all other known physical objects in terms of complexity within the entire cosmos. Remarkably, each individual possesses their own unique brain, residing within their own consciousness. We, at Crash Course, are eagerly anticipating the forthcoming months, during which we will delve into the realm of psychology. Our exploration will encompass its relevance to our lives, thoughts, emotions, and how it enhances our comprehension of one another, the world we inhabit, and our own selves.
