As a discipline, psychology has long sought to fend off accusations that it is a "soft" science . Philosopher of science Thomas Kuhn 's 1962 critique implied psychology overall was in a pre-paradigm state, lacking agreement on the type of overarching theory found in mature hard sciences such as chemistry and physics. Because some areas of psychology rely on research methods such as self-reports in surveys and questionnaires, critics asserted that psychology

The object of the game is to checkmate the opponent; this occurs when the opponent's king is in check, and there is no legal way to get it out of check. It is never legal for a player to make a move that puts or leaves the player's own king in check. In casual games, it is common to announce "check" when putting the opponent's king in check, but this

Skeptics have suggested that personality, thinking, and emotion cannot be directly measured and are often inferred from subjective self-reports, which may be problematic. Experimental psychologists have devised a variety of ways to indirectly measure these elusive phenomenological entities. Divisions still exist within the field, with some psychologists more oriented towards

Christian Wolff identified psychology as its own science, writing Psychologia Empirica in 1732 and Psychologia Rationalis in 1734. Immanuel Kant advanced the idea of anthropology as a discipline, with psychology an important subdivision. Kant, however, explicitly rejected the idea of an experimental psychology , writing that "the empirical doctrine of
10349-658: The direction of Hermann Göring 's cousin Matthias Göring , the Berlin Psychoanalytic Institute was renamed the Göring Institute. Freudian psychoanalysts were expelled and persecuted under the anti-Jewish policies of the Nazi Party , and all psychologists had to distance themselves from Freud and Adler , founders of psychoanalysis who were also Jewish. The Göring Institute was well-financed throughout
10480-575: The domestic economy. The Army rolled out its new General Classification Test to assess the ability of millions of soldiers. The Army also engaged in large-scale psychological research of troop morale and mental health . In the 1950s, the Rockefeller Foundation and Ford Foundation collaborated with the Central Intelligence Agency (CIA) to fund research on psychological warfare . In 1965, public controversy called attention to
10611-459: The early 20th century, Wolfgang Kohler , Max Wertheimer , and Kurt Koffka co-founded the school of Gestalt psychology of Fritz Perls . The approach of Gestalt psychology is based upon the idea that individuals experience things as unified wholes. Rather than reducing thoughts and behavior into smaller component elements, as in structuralism, the Gestaltists maintained that whole of experience
10742-572: The end of the 15th century, with standardization and universal acceptance by the end of the 19th century. Today, chess is one of the world's most popular games, with millions of players worldwide. Organized chess arose in the 19th century. Chess competition today is governed internationally by FIDE ( Fédération Internationale des Échecs ; the International Chess Federation). The first universally recognized World Chess Champion , Wilhelm Steinitz , claimed his title in 1886; Ding Liren
10873-404: The end of the game, " 1–0 " means White won, " 0–1 " means Black won, and " ½–½ " indicates a draw. Chess moves can be annotated with punctuation marks and other symbols . For example: " ! " indicates a good move; " !! " an excellent move; " ? " a mistake; " ?? " a blunder; " !? " an interesting move that may not be best; or " ?! " a dubious move not easily refuted. For example, one variation of
11004-448: The enemy pawn's two-square advance; otherwise, the right to do so is forfeited. For example, in the animated diagram, the black pawn advances two squares from g7 to g5, and the white pawn on f5 can take it en passant on g6 (but only immediately after the black pawn's advance). When a pawn advances to its eighth rank , as part of the move, it is promoted and must be exchanged for the player's choice of queen, rook, bishop, or knight of
11135-591: The establishment of university psychology departments and journals, and the establishment of groups including the Chinese Association of Psychological Testing (1930) and the Chinese Psychological Society (1937). Chinese psychologists were encouraged to focus on education and language learning. Chinese psychologists were drawn to the idea that education would enable modernization. John Dewey, who lectured to Chinese audiences between 1919 and 1921, had
11266-403: The field of psychology. In 1890, William James defined psychology as "the science of mental life, both of its phenomena and their conditions." This definition enjoyed widespread currency for decades. However, this meaning was contested, notably by radical behaviorists such as John B. Watson , who in 1913 asserted that the discipline is a natural science , the theoretical goal of which "is
11397-702: The field, female psychologists in the U.S. formed the National Council of Women Psychologists in 1941. This organization became the International Council of Women Psychologists after World War II and the International Council of Psychologists in 1959. Several associations including the Association of Black Psychologists and the Asian American Psychological Association have arisen to promote the inclusion of non-European racial groups in
11528-664: The first computer to beat a reigning World Champion in a match when it defeated Garry Kasparov . Today's chess engines are significantly stronger than the best human players and have deeply influenced the development of chess theory; however, chess is not a solved game . The rules of chess are published by FIDE (Fédération Internationale des Échecs; "International Chess Federation"), chess's world governing body, in its Handbook . Rules published by national governing bodies , or by unaffiliated chess organizations, commercial publishers, etc., may differ in some details. FIDE's rules were most recently revised in 2023. Chess sets come in
11659-503: The first junior high-school student to win the National High School Championship. He went on to win three invitational U.S. Junior Championships in 1973, 1974, and 1975. In 1977, at age 21, he became a grandmaster without first having been an international master . Christiansen tied for first place with Anatoly Karpov at Linares 1981. He won the 2001 Canadian Open Chess Championship . He also won Curaçao 2008 and
11790-423: The first rank in the following order, from left to right: rook, knight, bishop, queen, king, bishop, knight, rook. Pawns are placed on each square of the second rank. Black's position mirrors White's, with equivalent pieces on every file. The board is oriented so that the right-hand corner nearest each player is a light square; as a result the white queen always starts on a light square, while the black queen starts on
11921-407: The first rank moves to e2"). For pawns, no letter initial is used; so e4 means "pawn moves to the square e4". If the piece makes a capture, "x" is usually inserted before the destination square. Thus Bxf3 means "bishop captures on f3". When a pawn makes a capture, the file from which the pawn departed is used to identify the pawn making the capture, for example, exd5 (pawn on the e-file captures
12052-436: The g-file, 5th rank" (that is, to the square g5). Different initials may be used for other languages. In chess literature, figurine algebraic notation (FAN) is frequently used to aid understanding independent of language. To resolve ambiguities, an additional letter or number is added to indicate the file or rank from which the piece moved (e.g. Ngf3 means "knight from the g-file moves to the square f3"; R1e2 means "rook on
12183-506: The game is to checkmate (threaten with inescapable capture) the enemy king. There are also several ways a game can end in a draw . The recorded history of chess goes back at least to the emergence of a similar game, chaturanga , in seventh-century India . After its introduction in Persia , it spread to the Arab world and then to Europe. The rules of chess as they are known today emerged in Europe at
12314-498: The human mind was open to scientific investigation, even if the science is in some ways inexact. Mill proposed a "mental chemistry " in which elementary thoughts could combine into ideas of greater complexity. Gustav Fechner began conducting psychophysics research in Leipzig in the 1830s. He articulated the principle that human perception of a stimulus varies logarithmically according to its intensity. The principle became known as
12445-660: The idea of functionalism , an expansive approach to psychology that underlined the Darwinian idea of a behavior's usefulness to the individual. In 1890, James wrote an influential book, The Principles of Psychology , which expanded on the structuralism. He memorably described " stream of consciousness ." James's ideas interested many American students in the emerging discipline. Dewey integrated psychology with societal concerns, most notably by promoting progressive education , inculcating moral values in children, and assimilating immigrants. A different strain of experimentalism, with
12576-483: The landmark Brown v. Board of Education decision, leading to the end of legal segregation across the nation. Clark went on to be an influential figure in psychology, her work continuing to focus on minority youth. As the field of psychology developed throughout the latter half of the 20th century, women in the field advocated for their voices to be heard and their perspectives to be valued. Second-wave feminism did not miss psychology. An outspoken feminist in psychology
12707-418: The late nineteenth century enjoyed popularity (including the interest of scholars such as William James). Some people considered parapsychology to be part of "psychology". Parapsychology, hypnotism , and psychism were major topics at the early International Congresses. But students of these fields were eventually ostracized, and more or less banished from the Congress in 1900–1905. Parapsychology persisted for
12838-399: The major influence, with Marxism–Leninism the leading social doctrine and Pavlovian conditioning the approved means of behavior change. Chinese psychologists elaborated on Lenin's model of a "reflective" consciousness, envisioning an "active consciousness" ( pinyin : tzu-chueh neng-tung-li ) able to transcend material conditions through hard work and ideological struggle. They developed
12969-415: The neural, genetic, and cellular mechanisms that underlie behaviors involved in learning, memory, and fear responses. Cognitive neuroscientists , by using neural imaging tools, investigate the neural correlates of psychological processes in humans. Neuropsychologists conduct psychological assessments to determine how an individual's behavior and cognition are related to the brain. The biopsychosocial model
13100-414: The opponent choose. White moves first, after which players alternate turns, moving one piece per turn (except for castling , when two pieces are moved). A piece is moved to either an unoccupied square or one occupied by an opponent's piece, which is captured and removed from play. With the sole exception of en passant , all pieces capture by moving to the square that the opponent's piece occupies. Moving
13231-442: The opponent has enough pieces left to deliver checkmate). The duration of a game ranges from long (or "classical") games, which can take up to seven hours (even longer if adjournments are permitted), to bullet chess (under 3 minutes per player for the entire game). Intermediate between these are rapid chess games, lasting between one and two hours per game, a popular time control in amateur weekend tournaments. Time
13362-427: The piece chosen is indicated after the move (for example, e1=Q or e1Q ). Castling is indicated by the special notations 0-0 (or O-O ) for kingside castling and 0-0-0 (or O-O-O ) for queenside castling. A move that places the opponent's king in check usually has the notation " + " added. There are no specific notations for discovered check or double check . Checkmate can be indicated by " # ". At
13493-443: The piece on d5). Ranks may be omitted if unambiguous, for example, exd (pawn on the e-file captures a piece somewhere on the d-file). A minority of publications use " : " to indicate a capture, and some omit the capture symbol altogether. In its most abbreviated form, exd5 may be rendered simply as ed . An en passant capture may optionally be marked with the notation " e.p. " If a pawn moves to its last rank, achieving promotion,
13624-538: The piece that occupies the first rank at the beginning of the game. In descriptive notation, the common opening move 1.e4 is rendered as "1.P-K4" ("pawn to king four"). Another system is ICCF numeric notation , recognized by the International Correspondence Chess Federation though its use is in decline. In tournament games, players are normally required to keep a score (record of the game). For this purpose, only algebraic notation
13755-453: The prediction and control of behavior." Since James defined "psychology", the term more strongly implicates scientific experimentation. Folk psychology is the understanding of the mental states and behaviors of people held by ordinary people , as contrasted with psychology professionals' understanding. The ancient civilizations of Egypt, Greece, China, India, and Persia all engaged in the philosophical study of psychology. In Ancient Egypt
13886-594: The profession. The International Union of Psychological Science (IUPsyS) is the world federation of national psychological societies. The IUPsyS was founded in 1951 under the auspices of the United Nations Educational, Cultural and Scientific Organization (UNESCO) . Psychology departments have since proliferated around the world, based primarily on the Euro-American model. Since 1966, the Union has published
14017-494: The psychological laboratory that brought experimental psychology to the world. Wundt focused on breaking down mental processes into the most basic components, motivated in part by an analogy to recent advances in chemistry, and its successful investigation of the elements and structure of materials. Paul Flechsig and Emil Kraepelin soon created another influential laboratory at Leipzig, a psychology-related lab, that focused more on experimental psychiatry. James McKeen Cattell ,
14148-429: The required piece is not available (e.g. a second queen) an inverted rook is sometimes used as a substitute, but this is not recognized in FIDE-sanctioned games. A game can be won in the following ways: There are several ways a game can end in a draw : In competition, chess games are played with a time control . If a player's time runs out before the game is completed, the game is automatically lost (provided
14279-514: The results of natural selection or sexual selection over the course of human evolution. The history of the biological foundations of psychology includes evidence of racism. The idea of white supremacy and indeed the modern concept of race itself arose during the process of world conquest by Europeans. Carl von Linnaeus 's four-fold classification of humans classifies Europeans as intelligent and severe, Americans as contented and free, Asians as ritualistic, and Africans as lazy and capricious. Race
14410-550: The role of mental functions in individual and social behavior . Others explore the physiological and neurobiological processes that underlie cognitive functions and behaviors. Psychologists are involved in research on perception , cognition , attention , emotion , intelligence , subjective experiences , motivation , brain functioning , and personality . Psychologists' interests extend to interpersonal relationships , psychological resilience , family resilience , and other areas within social psychology . They also consider
14541-402: The rook is under attack, or if the rook crosses an attacked square. When a pawn makes a two-step advance from its starting position and there is an opponent's pawn on a square next to the destination square on an adjacent file, then the opponent's pawn can capture it en passant ("in passing"), moving to the square the pawn passed over. This can be done only on the turn immediately following
14672-407: The same color. Usually, the pawn is chosen to be promoted to a queen, but in some cases, another piece is chosen; this is called underpromotion . In the animated diagram , the pawn on c7 can be advanced to the eighth rank and be promoted. There is no restriction on the piece promoted to, so it is possible to have more pieces of the same type than at the start of the game (e.g., two or more queens). If
14803-481: The second half of the 20th century continued to do research that had large-scale impacts on the field of psychology. Mary Ainsworth 's work centered around attachment theory . Building off fellow psychologist John Bowlby , Ainsworth spent years doing fieldwork to understand the development of mother-infant relationships. In doing this field research, Ainsworth developed the Strange Situation Procedure,
14934-424: The soul can also never approach chemistry even as a systematic art of analysis or experimental doctrine, for in it the manifold of inner observation can be separated only by mere division in thought, and cannot then be held separate and recombined at will (but still less does another thinking subject suffer himself to be experimented upon to suit our purpose), and even observation by itself already changes and displaces
15065-415: The square were unoccupied. Pieces are generally not permitted to move through squares occupied by pieces of either color, except for the knight and during castling. When a king is under immediate attack, it is said to be in check . A move in response to a check is legal only if it results in a position where the king is no longer in check. There are three ways to counter a check: Castling
15196-417: The stage for further research to be done in social psychology , especially in gender construction . Other women in the field also continued advocating for women in psychology, creating the Association for Women in Psychology to criticize how the field treated women. E. Kitsch Child , Phyllis Chesler , and Dorothy Riddle were some of the founding members of the organization in 1969. The latter half of
15327-452: The standard system today is short-form algebraic notation . In this system, each square is uniquely identified by a set of coordinates, a – h for the files followed by 1 – 8 for the ranks. The usual format is The pieces are identified by their initials. In English, these are K (king), Q (queen), R (rook), B (bishop), and N (knight; N is used to avoid confusion with king). For example, Qg5 means "queen moves to
15458-601: The state of the observed object." In 1783, Ferdinand Ueberwasser (1752–1812) designated himself Professor of Empirical Psychology and Logic and gave lectures on scientific psychology, though these developments were soon overshadowed by the Napoleonic Wars . At the end of the Napoleonic era, Prussian authorities discontinued the Old University of Münster. Having consulted philosophers Hegel and Herbart , however, in 1825
15589-427: The technique of autogenic training , prominently advocated sterilization and euthanasia of men considered genetically undesirable, and devised techniques for facilitating this process. After the war, new institutions were created although some psychologists, because of their Nazi affiliation, were discredited. Alexander Mitscherlich founded a prominent applied psychoanalysis journal called Psyche . With funding from
15720-722: The unconscious mind. Research psychologists employ empirical methods to infer causal and correlational relationships between psychosocial variables . Some, but not all, clinical and counseling psychologists rely on symbolic interpretation . While psychological knowledge is often applied to the assessment and treatment of mental health problems, it is also directed towards understanding and solving problems in several spheres of human activity. By many accounts, psychology ultimately aims to benefit society. Many psychologists are involved in some kind of therapeutic role, practicing psychotherapy in clinical, counseling, or school settings. Other psychologists conduct scientific research on
15851-459: The unique experiences of individual humans, which cannot be understood only as data points within a larger population. Critics inside and outside the field have argued that mainstream psychology has become increasingly dominated by a "cult of empiricism", which limits the scope of research because investigators restrict themselves to methods derived from the physical sciences. Feminist critiques have argued that claims to scientific objectivity obscure
15982-548: The universe in term of a division of physical reality and mental reality as well as the interaction between the physical and the mental. Chinese philosophy also emphasized purifying the mind in order to increase virtue and power. An ancient text known as The Yellow Emperor's Classic of Internal Medicine identifies the brain as the nexus of wisdom and sensation, includes theories of personality based on yin–yang balance, and analyzes mental disorder in terms of physiological and social disequilibria. Chinese scholarship that focused on
16113-413: The values and agenda of (historically) mostly male researchers. Jean Grimshaw, for example, argues that mainstream psychological research has advanced a patriarchal agenda through its efforts to control behavior. Psychologists generally consider biology the substrate of thought and feeling, and therefore an important area of study. Behaviorial neuroscience, also known as biological psychology, involves
16244-498: The war with a mandate to create a "New German Psychotherapy." This psychotherapy aimed to align suitable Germans with the overall goals of the Reich. As described by one physician, "Despite the importance of analysis, spiritual guidance and the active cooperation of the patient represent the best way to overcome individual mental problems and to subordinate them to the requirements of the Volk and
16375-459: The world every year catering to players of all levels. Tournaments with a small number of players may use the round-robin format, in which every player plays one game against every other player. For a large number of players, the Swiss system may be used, in which each player is paired against an opponent who has the same (or as similar as possible) score in each round. In either case, a player's score
16506-654: The world's strongest players. Examples include Spain's Linares event, Monte Carlo's Melody Amber tournament, the Dortmund Sparkassen meeting, Sofia's M-tel Masters , and Wijk aan Zee's Tata Steel tournament. Regular team chess events include the Chess Olympiad and the European Team Chess Championship . The World Chess Solving Championship and World Correspondence Chess Championships include both team and individual events; these are held independently of FIDE. Psychology Psychology
16637-459: Was Naomi Weisstein , who was an accomplished researcher in psychology and neuroscience , and is perhaps best known for her paper, "Kirche, Kuche, Kinder as Scientific Law: Psychology Constructs the Female." Psychology Constructs the Female criticized the field of psychology for centering men and using biology too much to explain gender differences without taking into account social factors. Her work set
16768-607: Was a turning point for women's recognition within the field of psychology. In addition to the contributions made by Leta Stetter Hollingworth and Anna Freud , Mary Whiton Calkins invented the paired associates technique of studying memory and developed self-psychology . Karen Horney developed the concept of " womb envy " and neurotic needs. Psychoanalyst Melanie Klein impacted developmental psychology with her research of play therapy . These great discoveries and contributions were made during struggles of sexism , discrimination , and little recognition for their work. Women in
16899-467: Was also used to justify the construction of socially specific mental disorders such as drapetomania and dysaesthesia aethiopica —the behavior of uncooperative African slaves. After the creation of experimental psychology, "ethnical psychology" emerged as a subdiscipline, based on the assumption that studying primitive races would provide an important link between animal behavior and the psychology of more evolved humans. A tenet of behavioral research
17030-550: Was another woman in psychology that changed the field with her research. She was one of the first African-Americans to receive a doctoral degree in psychology from Columbia University , along with her husband, Kenneth Clark . Her master's thesis, "The Development of Consciousness in Negro Pre-School Children," argued that black children's self-esteem was negatively impacted by racial discrimination . She and her husband conduced research building off her thesis throughout
17161-788: Was established by Carolyn Attneave . Harriet McAdoo was appointed to the White House Conference on Families in 1979. Dr. Kay Redfield Jamison , named one of Time Magazine's "Best Doctors in the United States" is a lecturer, psychologist, and writer. She is known for her vast modern contributions to bipolar disorder and her books An Unquiet Mind (Published 1995) and Nothing Was the Same (Published in 2009). Having Bipolar Disorder herself, she has written several memoirs about her experience with suicidal thoughts , manic behaviors, depression , and other issues that arise from being Bipolar . Dr. Angela Neal-Barnett views psychology through
