History of Psychology



PSY/310 Version 2
 
     The birth of psychology began with the quest of early philosophers such as Socrates, Plato, and Aristotle; however, it was not until the seventeenth century that philosophy broached the realm of scientific study becoming a form of psychology.  Young philosophers benefiting from the dramatic Renaissance period of the fifteenth and sixteenth centuries began to question the philosophy of undisputable church authority.  This period, “known as an era of revolutionary developments in science” spurred not only the superior minds of Galileo and Sir Isaac Newton but also psychologies most influential founders: Rene Descartes (1596-1650), David Hartley (1705-1757), Robert Whytt (1714-1766), David Hume (1711-1776), and Franz Josef Gall (1758-1828) (Goodwin, 2008, p. 32).  However, regardless of whose philosophical view originated the study of psychology, or who exposed psychology into western tradition, advances in the nineteenth century firmly secured psychology as a formal scientific discipline.

Historical Beginnings: Philosophy and Physiology

     Early philosophy relied on observation and logic; however, by the end of the renaissance period philosophers began to examine the unquestionable.  Descartes, more a scientist than a philosopher was known as a rationalist because of his belief that reason was the way to truth.  Descartes was also credited with “arguing for a clear separation between mind (or ‘soul’) and body” (Goodwin, 2008, p. 34).  Furthermore, he worked with optics and physiology in an attempt to uncover conscious and unconscious reflexes associated with the mind-body question.  Hartley, on the other hand was a dualist on the mind-body theory.  A medical practitioner who argued for an association theory of how the mind worked; psychophysical parallelism (both mental and physical work separately yet together).  Whytt, “the leading neurologist of his day” used experimental spinal cord research as associated with reflexes.  His discoveries suggested that motor nerve function involved sensory input.  Hume worked on the basis that “understanding is rooted in experience,” thus; through experiential association impressions and ideas form (p. 46).  Furthermore, Hume was the first to suggest the “three laws of association:” resemblance, contiguity, and cause and effect (p. 47).  Finally, the breakthrough psychology needed came from research on the brain itself.  Gall, a physician and comparative anatomist proposed a theory of localization of brain function called phrenology.  Additionally, his discoveries of the fibers that connect the two hemispheres of the brain confirm contralateral function.  However, it was not until Galls associate (Spurzheim) brought phrenology to America that it reached its most significant contribution.          

Western Contributions to Psychology

     Although western psychology has imperialist influences, the contributions of such research as phrenology aided the American belief that anyone can be successful in life and opened the gateway to future neurological research.  John Locke (1632-1704) was an Oxford philosopher enthralled by the physical sciences of the seventeenth century (Goodwin, 2008).  Extending his studies to epistemology, he later wrote An Essay Concerning Human Understanding (1690) that provided him with notoriety throughout the field of psychology.  One of Locke’s most influential ponderings was that the mind is a blank page, therefore experience creates knowledge and thus the majority of those experiences are sensations.  Furthermore, “defective senses… [can] produce a distorted view of the world” (p. 41).  Another influential philosopher whose contributions to western psychology had a significant impact was George Berkley (1685-1753).  Emigrating to America from Ireland, Berkley produced two books focusing on the analysis of sensory processes: “An Essay Towards a New Theory of Vision (1709) and Treatise Concerning the Principles of Human Knowledge (1710)” (Goodwin, 2008, p. 43).  His suggestions about optics and perception are still relevant, more than three centuries later.  As indicated by Daniel Robinson and restated by Goodwin (2008) “Berkeley ‘rendered epistemology a branch of psychology, and the two have never been divorced since’” (p. 45).

Science of Psychology into the Nineteenth Century

     Experimental research through physiology and mathematical contributions made psychology a formal science in the nineteenth century through the works of such scientists as William Wundt (1832-1920), William James (1842-1910), and Sigmund Freud (1856-1939) to name but a few.  Wundt, known as the “father of experimental psychology” was the founder of the first experimental laboratory, thus marking the distinction between psychology as a philosophy or a physiology to that of a science (Kim, 2008, para 1).  Furthermore, Wundt is also the founder of the structuralism perspective of psychology, which believes conscious experiences are the thoughts, feelings, and emotions that people express.  James, called the father of American psychology introduced one of the most influential psychology books; The Principles of Psychology (1890).  His descriptions of human experience, behavior, and nature produced extensive insight into “the phenomena of psychopathology and exceptional mental states” (Wozniak, 1999, para 2).  James is also credited with beginning the functionalist perspective, which emphasizes the adaptiveness of mental and behavioral processes.  Following in his footsteps, Freud proposed a psychoanalytical perspective of treating psychopathological patients.  Trained as a neurologist, Freud found inspiration in Darwin’s evolutionary perspective, thus relating all psychological difficulties back to a psychosexual basis (a basic human drive).  Working with hysteria (mostly in women) his speculations that associated symptoms stem from extreme sexual frustration created much controversy.  Freud eventually introduced his theories of id, ego, and superego as the unconscious desires to fulfill basic human needs.   Although Freud’s theories remain controversial, they earned him the classification of the father of psychoanalysis and opened the door for future theories and practices (e.g., clinical, neurological, and behavioral) within the psychological realm.

     As stated, each philosophical view, including that of western philosophers have provided significant advances toward the nineteenth century introduction of psychology as a formal scientific discipline. Whether it is the empirical challenges of mind-body issues that presented itself in the early days of physiology or the philosophical questions of how the mind works physiological research and study prevail.  Some of these philosophical and physiological theories have been carried over many continents to further advance their scientific growth, such as that of Locke and Berkeley’s study of epistemology in America.  Of which, both helped to create this new scientific perspective of the nineteenth century.  Even though experimental research produced the formal discipline known as scientific psychology its growth continues even in modern times.  However, as psychology moves to a more cognitive study there is yet to be even more growth within the discipline.
