It is thus concerned with brain cells, brain structures and components, brain chemistry, and how all this leads to speech and action. It is also important to understand how we take in information from our five senses. Several persons contributed to the development of physiological psychology; such as Charles Darwin who were a biologist and whose theory of evolution revolutionized biology and strongly influenced early psychologists, René Descartes a philosopher and mathematician, Hermann von Helmholtz and Johannes Muller etc.Amongst them one of …show more content…

(Johannes Muller, 2014). The doctrine of specific nerve energies was his most important contribution to the study of physiology of behavior. He observed that all nerves carry the same basic message, but we discern the messaged of different nerves not the same. Because of his doctrine of specific nerve, experiments were performed directly on the brain of animals, which was done by Pierre Flourens a French physiologist. This was knows as experimental ablation. There after he claimed to have found the part of the brain which was responsible for breathing, controlling heart rate, purposeful movements and auditory reflexes. Soon after this experimental ablation was applied to a human brain. This observation led to show that a portion of the cerebral cortex on the front part of the left side of the brain performs the functions that are necessary for speech. This remains important to the understanding of the brain. (Physiology of Behavior,

  • William James’ and the Legacy He Left Behind

    Many people attribute modern psychology to psychologist such as Sigmund Freud, Ivan Pavlov, and B.F. Skinner. Though, they were a part of developing modern psychology, many forget to recognize important founders such as William James. According to King, Viney and Woody, James came from a family with a strict father, raised in tolerance. James and his father had many encounters because of their different views. They were a wealthy and cultured family. James attended Harvard, studying a broad spectrum of just about everything. He finally received his medical degree in 1869, but then became depressed and anxious about life. He was not fond of medicine and was then offered to teach a course in the Relations between Psychology and Physiology. He was also the founder of Harvard’s first psychology laboratory. James then began to teach psychology as well as writing the first U.S. psychology text, Principles of Psychology, in 1890; this book was the main psychology textbook for many years to come (p.284). James was well known for his philosophy, which he explored many areas. For example individualism, which he believed that circumstances shape individuals and then individuals shape the world also that we understand reality only through individual experiences. Pluralism was another view which he believed that there are many ways to understand the world, and a variety of methods and topics to study. Also, for James pragmatism was a belief that if an idea worked it was valid; these ideas should have “cash value” as he stated. He meant that these ideas should be useful and apply them to the real world. Although philosophy was a major part of his work, he was also known as the American founder of psychology (King, Viney &Woody 2013, p.286). Wi...

  • Psychogeography Essay

    824 Words  | 2 Pages

    Throughout history the way we live, the way we interact with other people and the way and reason we create art has been carefully structured by countless factors that we encounter every day of our lives. Many of these factors can be grouped together and categorised as 'Psychogeography', the term coined by French theorist Guy Debord in 1955. Debord's definition described the term as 'the study of specific effects of the geographical environment, consciously organised or not, on the emotions & behaviour of individuals’(1), in his work he deeply considered the effects that physical structure in the environment has on the way humans interact with each other and the space they inhabit. Guy Debord was a part of an organization that encouraged and supported the ideas of like minded artists, theorists and intellectuals called the 'Situationist International' (SI), whose ideologies were of prioritising the study and discussion of real life; temporal subjects that concerned modern society. A principle cultivated by the SI that closely relates to psychogeography is the idea of dérive ("drift"). Debord illustrates the theory of dérive as an environmental distraction, 'In a dérive one or more persons during a certain period drop their usual motives for movement and action, their relations, their work and leisure activities, and let themselves be drawn by the attractions of the terrain and the encounters they find there'(2). Dérive alludes that when humans detect changes in elements of our geographical surroundings natural instinct causes us to change our paths. Debord also describes the act of dérive in a way that connotes the idea of invisible auras that surround individual locations, "The sudden change of ambiance in a street within the spa...

    ...eveloped into more extensive studies of the brain and its functioning. Another huge contribution that Gall made through his work was the idea of brain localization and the area of the brain that controls speech, language, and also word memory. Gall was also the first to discover that the white matter of the brain contained fibers or axons, and the gray matter in the brain contained neurons or cell bodies. Franz Joseph Gall is now known as one of the most influential people in history because of his ground work of Phrenology that led to later discoveries. His work led to many other scientific branches to become developed such as craniology, psychognomy, and anthropometry. ( Biographies on Psychologists.)

  • History of Psychology

    Psychology started, and had a long history, as a topic within the fields of philosophy and physiology. It then became an independent field of its own through the work of the German Wilhelm Wundt, the founder of experimental psychology and structuralism. Wundt stressed the use of scientific methods in psychology, particularly through the use of introspection. In 1875, a room was set-aside for Wundt for demonstrations in what we now call sensation and perception. This is the same year that William James set up a similar lab at Harvard. Wilhelm Wundt and William James are usually thought of as the fathers of psychology, as well as the founders of psychology?s first two great ?schools? Structuralism and Functionalism. Psychologist Edward B Titchner said; ?to study the brain and the unconscious we should break it into its structural elements, after that we can construct it into a whole and understand what it does.?
