History of psychology

See also: Psychoanalysis § History
Experimentation was not the only approach to psychology in the German-speaking world at this time. Starting in the 1890s, employing the case study technique, the Viennese physician Sigmund Freud developed and applied the methods of hypnosis, free association, and dream interpretation to reveal putatively unconscious beliefs and desires that he argued were the underlying causes of his patients' "hysteria". He dubbed this approach psychoanalysis. Freudian psychoanalysis is particularly notable for the emphasis it places on the course of an individual's sexual development in pathogenesis. Psychoanalytic concepts have had a strong and lasting influence on Western culture, particularly on the arts. Although its scientific contribution is still a matter of debate, both Freudian and Jungian psychology revealed the existence of compartmentalized thinking, in which some behavior and thoughts are hidden from consciousness – yet operative as part of the complete personality. Hidden agendas, a bad conscience, or a sense of guilt, are examples of the existence of mental processes in which the individual is not conscious, through choice or lack of understanding, of some aspects of their personality and subsequent behavior.
Psychoanalysis examines mental processes which affect the ego. An understanding of these theoretically allows the individual greater choice and consciousness with a healing effect in neurosis and occasionally in psychosis, both of which Richard von Krafft-Ebing defined as "diseases of the personality".
Freud founded the International Psychoanalytic Association in 1910, inspired also by Ferenczi.^[58] Main theoretical successors were Anna Freud (his daughter) and Melane Klein, particularly in child psychoanalysis, both inaugurating competing concepts; in addition to those who became dissidents and developed interpretations different from Freud's psychoanalytic one, thus called by some neo-freudians, or more correctly post-freudians:^[59] the most known are Alfred Adler (individual psychology), Carl Gustav Jung (analytical psychology), Otto Rank, Karen Horney, Erik Erikson and Erich Fromm.
Jung was an associate of Freud's who later broke with him over Freud's emphasis on sexuality. Working with concepts of the unconscious first noted during the 1800s (by John Stuart Mill, Krafft-Ebing, Pierre Janet, Théodore Flournoy and others), Jung defined four mental functions which relate to and define the ego, the conscious self:

1. 
   Sensation, which tell consciousness that something is there.
   
2. 
   Feelings, which consist of value judgments, and motivate our reaction to what we have sensed.
   
3. 
   Intellect, an analytic function that compares the sensed event to all known others and gives it a class and category, allowing us to understand a situation within a historical process, personal or public.
   
4. 
   And intuition, a mental function with access to deep behavioral patterns, being able to suggest unexpected solutions or predict unforeseen consequences, "as if seeing around corners" as Jung put it.
   

Jung insisted on an empirical psychology on which theories must be based on facts and not on the psychologist's projections or expectations.
Early American[edit]
Around 1875 the Harvard physiology instructor (as he then was), William James, opened a small experimental psychology demonstration laboratory for use with his courses. The laboratory was never used, at that time, for original research, and so controversy remains as to whether it is to be regarded as the "first" experimental psychology laboratory or not. In 1878, James gave a series of lectures at Johns Hopkins University entitled "The Senses and the Brain and their Relation to Thought" in which he argued, contra Thomas Henry Huxley, that consciousness is not epiphenomenal, but must have an evolutionary function, or it would not have been naturally selected in humans. The same year James was contracted by Henry Holt to write a textbook on the "new" experimental psychology. If he had written it quickly, it would have been the first English-language textbook on the topic. It was twelve years, however, before his two-volume The Principles of Psychology would be published. In the meantime textbooks were published by George Trumbull Ladd of Yale (1887) and James Mark Baldwin then of Lake Forest College (1889).
William James was one of the founders of the American Society for Psychical Research in 1885, which studied psychic phenomena (parapsychology), before the creation of the American Psychological Association in 1892. James was also president of the British society that inspired the United States' one, the Society for Psychical Research, founded in 1882, which investigated psychology and the paranormal on topics such as mediumship, dissociation, telepathy and hypnosis, and it innovated research in psychology, by which, according to science historian Andreas Sommer, were "devised methodological innovations such as randomized study designs" and conducted "the first experiments investigating the psychology of eyewitness testimony (Hodgson and Davey, 1887), [and] empirical and conceptual studies illuminating mechanisms of dissociation and hypnotism"; Its members also initiated and organised the International Congresses of Physiological/Experimental psychology.^[60]
In 1879 Charles Sanders Peirce was hired as a philosophy instructor at Johns Hopkins University. Although better known for his astronomical and philosophical work, Peirce also conducted what are perhaps the first American psychology experiments, on the subject of color vision, published in 1877 in the American Journal of Science (see Cadwallader, 1974). Peirce and his student Joseph Jastrow published "On Small Differences in Sensation" in the Memoirs of the National Academy of Sciences, in 1884. In 1882, Peirce was joined at Johns Hopkins by G. Stanley Hall, who opened the first American research laboratory devoted to experimental psychology in 1883. Peirce was forced out of his position by scandal and Hall was awarded the only professorship in philosophy at Johns Hopkins. In 1887 Hall founded the American Journal of Psychology, which published work primarily emanating from his own laboratory. In 1888 Hall left his Johns Hopkins professorship for the presidency of the newly founded Clark University, where he remained for the rest of his career.
Soon, experimental psychology laboratories were opened at the University of Pennsylvania (in 1887, by James McKeen Cattell), Indiana University (1888, William Lowe Bryan), the University of Wisconsin (1888, Joseph Jastrow), Clark University (1889, Edmund Sanford), the McLean Asylum (1889, William Noyes), and the University of Nebraska (1889, Harry Kirke Wolfe). However, it was Princeton University's Eno Hall, built in 1924, that became the first university building in the United States to be devoted entirely to experimental psychology when it became the home of the university's Department of Psychology.^[61]
In 1890, William James' The Principles of Psychology finally appeared, and rapidly became the most influential textbook in the history of American psychology. It laid many of the foundations for the sorts of questions that American psychologists would focus on for years to come. The book's chapters on consciousness, emotion, and habit were particularly agenda-setting.
One of those who felt the impact of James' Principles was John Dewey, then professor of philosophy at the University of Michigan. With his junior colleagues, James Hayden Tufts (who founded the psychology laboratory at Michigan) and George Herbert Mead, and his student James Rowland Angell, this group began to reformulate psychology, focusing more strongly on the social environment and on the activity of mind and behavior than the psychophysics-inspired physiological psychology of Wundt and his followers had heretofore. Tufts left Michigan for another junior position at the newly founded University of Chicago in 1892. A year later, the senior philosopher at Chicago, Charles Strong, resigned, and Tufts recommended to Chicago president William Rainey Harper that Dewey be offered the position. After initial reluctance, Dewey was hired in 1894. Dewey soon filled out the department with his Michigan companions Mead and Angell. These four formed the core of the Chicago School of psychology.
In 1892, G. Stanley Hall invited 30-some psychologists and philosophers to a meeting at Clark with the purpose of founding a new American Psychological Association (APA). (On the history of the APA, see Evans, Staudt Sexton, & Cadwallader, 1992.) The first annual meeting of the APA was held later that year, hosted by George Stuart Fullerton at the University of Pennsylvania. Almost immediately tension arose between the experimentally and philosophically inclined members of the APA. Edward Bradford Titchener and Lightner Witmer launched an attempt to either establish a separate "Section" for philosophical presentations, or to eject the philosophers altogether. After nearly a decade of debate, a Western Philosophical Association was founded and held its first meeting in 1901 at the University of Nebraska. The following year (1902), an American Philosophical Association held its first meeting at Columbia University. These ultimately became the Central and Eastern Divisions of the modern American Philosophical Association.
In 1894, a number of psychologists, unhappy with the parochial editorial policies of the American Journal of Psychology approached Hall about appointing an editorial board and opening the journal out to more psychologists not within Hall's immediate circle. Hall refused, so James McKeen Cattell (then of Columbia) and James Mark Baldwin (then of Princeton) co-founded a new journal, Psychological Review, which rapidly grew to become a major outlet for American psychological researchers.^[62][63]
Beginning in 1895, James Mark Baldwin (Princeton, Hopkins) and Edward Bradford Titchener (Cornell) entered into an increasingly acrimonious dispute over the correct interpretation of some anomalous reaction time findings that had come from the Wundt laboratory (originally reported by Ludwig Lange and James McKeen Cattell). In 1896, James Rowland Angell and Addison W. Moore (Chicago) published a series of experiments in Psychological Review appearing to show that Baldwin was the more correct of the two. However, they interpreted their findings in light of John Dewey's new approach to psychology, which rejected the traditional stimulus-response understanding of the reflex arc in favor of a "circular" account in which what serves as "stimulus" and what as "response" depends on how one views the situation. The full position was laid out in Dewey's landmark article "The Reflex Arc Concept in Psychology" which also appeared in Psychological Review in 1896.
Titchener responded in Philosophical Review (1898, 1899) by distinguishing his austere "structural" approach to psychology from what he termed the Chicago group's more applied "functional" approach, and thus began the first major theoretical rift in American psychology between Structuralism and Functionalism. The group at Columbia, led by James McKeen Cattell, Edward L. Thorndike, and Robert S. Woodworth, was often regarded as a second (after Chicago) "school" of American Functionalism (see, e.g., Heidbredder, 1933), although they never used that term themselves, because their research focused on the applied areas of mental testing, learning, and education. Dewey was elected president of the APA in 1899, while Titchener dropped his membership in the association. (In 1904, Titchener formed his own group, eventually known as the Society of Experimental Psychologists.) Jastrow promoted the functionalist approach in his APA presidential address of 1900, and Angell adopted Titchener's label explicitly in his influential textbook of 1904 and his APA presidential address of 1906. In reality, Structuralism was, more or less, confined to Titchener and his students.^{[citation needed]} (It was Titchener's former student E. G. Boring, writing A History of Experimental Psychology [1929/1950, the most influential textbook of the 20th century about the discipline], who launched the common idea that the structuralism/functionalism debate was the primary fault line in American psychology at the turn of the 20th century.) Functionalism, broadly speaking, with its more practical emphasis on action and application, better suited the American cultural "style" and, perhaps more important, was more appealing to pragmatic university trustees and private funding agencies.^{[citation needed]}
Early French[edit]
Jules Baillarger founded the Société Médico-Psychologique in 1847, one of the first associations of its kind and which published the Annales Medico-Psychologiques.^[32] France already had a pioneering tradition in psychological study, and it was relevant the publication of Précis d'un cours de psychologie ("Summary of a Psychology Course") in 1831 by Adolphe Garnier, who also published theTraité des facultés de l'âme, comprenant l'histoire des principales théories psychologiques ("Treatise of the Faculties of the Soul, comprising the history of major psychological theories") in 1852.^[64] Garnier was called "the best monument of psychological science of our time" by Revue des Deux Mondes in 1864.^[65][53]
In no small measure because of the conservatism of the reign of Louis Napoléon (president, 1848–1852; emperor as "Napoléon III", 1852–1870), academic philosophy in France through the middle part of the 19th century was controlled by members of the eclectic and spiritualist schools, led by figures such as Victor Cousin (1792–1867), Thédodore Jouffroy (1796–1842), and Paul Janet (1823–1899). These were traditional metaphysical schools, opposed to regarding psychology as a natural science. With the ouster of Napoléon III after the débacle of the Franco-Prussian War, new paths, both political and intellectual, became possible. From the 1870 forward, a steadily increasing interest in positivist, materialist, evolutionary, and deterministic approaches to psychology developed, influenced by, among others, the work of Hyppolyte Taine (1828–1893) (e.g., De L'Intelligence, 1870) and Théodule Ribot (1839–1916) (e.g., La Psychologie Anglaise Contemporaine, 1870).
In 1876, Ribot founded Revue Philosophique (the same year as Mind was founded in Britain), which for the next generation would be virtually the only French outlet for the "new" psychology (Plas, 1997). Although not a working experimentalist himself, Ribot's many books were to have profound influence on the next generation of psychologists. These included especially his L'Hérédité Psychologique (1873) and La Psychologie Allemande Contemporaine (1879). In the 1880s, Ribot's interests turned to psychopathology, writing books on disorders of memory (1881), will (1883), and personality (1885), and where he attempted to bring to these topics the insights of general psychology. Although in 1881 he lost a Sorbonne professorship in the History of Psychological Doctrines to traditionalist Jules Soury (1842–1915), from 1885 to 1889 he taught experimental psychology at the Sorbonne. In 1889 he was awarded a chair at the Collège de France in Experimental and Comparative Psychology, which he held until 1896 (Nicolas, 2002).
France's primary psychological strength lay in the field of psychopathology. The chief neurologist at the Salpêtrière Hospital in Paris, Jean-Martin Charcot (1825–1893), had been using the recently revivied and renamed (see above) practice of hypnosis to "experimentally" produce hysterical symptoms in some of his patients. Two of his students, Alfred Binet (1857–1911) and Pierre Janet (1859–1947), adopted and expanded this practice in their own work.
In 1889, Binet and his colleague Henri Beaunis (1830–1921) co-founded, at the Sorbonne, the first experimental psychology laboratory in France. Just five years later, in 1894, Beaunis, Binet, and a third colleague, Victor Henri (1872–1940), co-founded the first French journal dedicated to experimental psychology, L'Année Psychologique. In the first years of the 20th century, Binet was requested by the French government to develop a method for the newly founded universal public education system to identify students who would require extra assistance to master the standardized curriculum. In response, with his collaborator Théodore Simon (1873–1961), he developed the Binet-Simon Intelligence Test, first published in 1905 (revised in 1908 and 1911). Although the test was used to effect in France, it would find its greatest success (and controversy) in the United States, where it was translated into English by Henry H. Goddard (1866–1957), the director of the Training School for the Feebleminded in Vineland, New Jersey, and his assistant, Elizabeth Kite (a translation of the 1905 edition appeared in the Vineland Bulletin in 1908, but much better known was Kite's 1916 translation of the 1908 edition, which appeared in book form). The translated test was used by Goddard to advance his eugenics agenda with respect to those he deemed congenitally feeble-minded, especially immigrants from non-Western European countries. Binet's test was revised by Stanford professor Lewis M. Terman (1877–1956) into the Stanford-Binet IQ test in 1916. With Binet's death in 1911, the Sorbonne laboratory and L'Année Psychologique fell to Henri Piéron (1881–1964). Piéron's orientation was more physiological that Binet's had been.
Pierre Janet became the leading psychiatrist in France, being appointed to the Salpêtrière (1890–1894), the Sorbonne (1895–1920), and the Collège de France (1902–1936). In 1904, he co-founded the Journale de Psychologie Normale et Pathologique with fellow Sorbonne professor Georges Dumas (1866–1946), a student and faithful follower of Ribot. Whereas Janet's teacher, Charcot, had focused on the neurological bases of hysteria, Janet was concerned to develop a scientific approach to psychopathology as a mental disorder. His theory that mental pathology results from conflict between unconscious and conscious parts of the mind, and that unconscious mental contents may emerge as symptoms with symbolic meanings led to a public priority dispute with Sigmund Freud.
