The Evolution of Psychology: From Structuralism to Functionalism and Psychoanalysis

Wilhelm Wundt founded the first experimental psychology laboratory in Germany in 1879. He also established the first psychological school, initially named conciencialismo, later renamed to structuralism. This school was influenced by psychophysics, particularly the work of Ernest Weber and Gustav Theodor Fechner.

Modern psychology has shifted from traditional schools to diverse perspectives. The field is now holistic and integrative, combining approaches like behaviorism, cognitivism, and psychoanalysis. This evolution allows for a more comprehensive understanding of human and animal behavior.

Ernest Weber and Gustav Theodor Fechner, prominent psychophysicists, studied the mind and sensation. Their research findings were instrumental in Wilhelm Wundt's establishment of the first psychological laboratory and the development of structuralism.

Wilhelm Wundt, a physician, physiologist, and philosopher, utilized experimental methods like introspection to study the basic elements of consciousness. He believed in fragmenting the mind into elements for analysis, combining introspection with physiological experimentation.

The discussion delves into the comparison between concencialismo and funcionalismo in psychology. Concencialismo, initially known as estructuralismo, was the first psychological school, focusing on introspection and the idea that consciousness is formed by 30,000 mental atoms of images, sensations, and feelings. However, it was quickly criticized for being theoretical and impractical, lacking practical applications like psychotherapy or behavior modeling. On the other hand, funcionalismo, led by William James at Harvard in 1895, emphasized understanding how the mind functions rather than its structure. It aimed to use biological influences, particularly Darwinian principles, to adapt better to the world and solve problems, making it more practical and scientific than concencialismo.

Gun, considered the father of psychology, played a crucial role in establishing psychology as a science separate from philosophy and metaphysical speculation. Gun's experiments, though rudimentary, granted psychology the status of a science, distinguishing it from philosophy and providing a scientific foundation for the field. Gun's contribution was significant in shaping the early development of psychology and moving it towards a more empirical and scientific discipline.

Functionalism emerged as a reaction and critique to structuralism. It focused on understanding how the mind functions, its purposes, intentions, and adaptation processes. The intelligence of a child, for example, was seen as crucial for problem-solving and better adaptation to daily life. The method used by functionalism was extrospection, not introspection, as discussed in the methods class.

The key findings of functionalism emphasized that the mind is not a static entity waiting to be studied. It cannot be fragmented into parts but is a continuous, flowing process. The mind is always engaged in activities like linking, remembering, and imagining. It cannot be studied in isolation but as a whole entity, similar to perceiving a blackboard as a complete object rather than a collection of separate parts.

Functionalism had significant biological influences, leading to the development of various branches within psychology. These included evolutionary psychology, developmental psychology, educational psychology, and the application of psychological tests. Terms from biology such as inheritance, instinct, adaptation, development, and maturation were integrated into psychology by functionalism.

In 1896, while functionalism was developing in the United States, psychoanalysis emerged in Vienna, Austria. Sigmund Freud, an Austrian physician and neurologist, introduced psychoanalysis as a study of the unconscious mind. Freud compared the mind to an iceberg, with consciousness representing only a small visible part, while the unconscious mind was the larger, hidden portion that influences conscious thoughts and behaviors.

Freud's psychoanalysis delved into the depths of the mind, focusing on the unconscious. He was known as the 'archaeologist of the mind' for his exploration of past experiences and their impact on present behavior. Psychoanalysis was also referred to as 'depth psychology' for its study of the profound levels of the mind, particularly the unconscious. Freud's work was instrumental in uncovering the hidden motivations and conflicts that shape human behavior.

Freud, known as an archaeologist of the mind, believed that all current situations are deeply rooted in childhood and past experiences. He introduced the concept of pansexualism, where every behavior was seen through a sexual lens. For Freud, actions like hair caressing, crossing legs, or licking lips all had underlying sexual motivations. Despite facing criticism for his sexual interpretations, Freud's work delved into the unconscious mind and the libido, emphasizing the role of sexual energy in human behavior.

Freud initially used hypnosis to explore the unconscious but later switched to free association, where patients would speak freely to reveal their unconscious thoughts. The most rigorous method he employed was dream interpretation, considering dreams as a window to the unconscious mind. Freud's techniques, including free association and dream analysis, revolutionized psychology and laid the foundation for psychoanalysis.

Freud's contributions extended to the fields of psychology, personality theory, and psychotherapy. He introduced groundbreaking ideas on personality development and mental disorders, shaping the way we understand human behavior and paving the way for modern psychotherapy practices.
