Wilhelm Maximilian Wundt was a German physiologist, philosopher, and professor, one of the fathers of modern psychology. Wundt, who distinguished psychology as a science from philosophy and biology, was the first person ever to call himself a psychologist.
In psychoanalysis and other psychological theories, the unconscious mind is the part of the psyche that is not available to introspection. Although these processes exist beneath the surface of conscious awareness, they are thought to exert an effect on conscious thought processes and behavior. Empirical evidence suggests that unconscious phenomena include repressed feelings and desires, memories, automatic skills, subliminal perceptions, and automatic reactions. The term was coined by the 18th-century German Romantic philosopher Friedrich Schelling and later introduced into English by the poet and essayist Samuel Taylor Coleridge.
In the philosophy of mind, functionalism is the thesis that each and every mental state is constituted solely by its functional role, which means its causal relation to other mental states, sensory inputs, and behavioral outputs. Functionalism developed largely as an alternative to the identity theory of mind and behaviorism.
Introspection is the examination of one's own conscious thoughts and feelings. In psychology, the process of introspection relies on the observation of one's mental state, while in a spiritual context it may refer to the examination of one's soul. Introspection is closely related to human self-reflection and self-discovery and is contrasted with external observation.
Margaret Floy Washburn, was a leading American psychologist in the early 20th century, was best known for her experimental work in animal behavior and motor theory development. She was the first woman to be granted a PhD in psychology (1894); the second woman, after Mary Whiton Calkins, to serve as president of the American Psychological Association (1921); and the first woman elected to the Society of Experimental Psychologists. A Review of General Psychology survey, published in 2002, ranked Washburn as the 88th most cited psychologist of the 20th century, tied with John Garcia, James J. Gibson, David Rumelhart, Louis Leon Thurstone, and Robert S. Woodworth.
Edward Bradford Titchener was an English psychologist who studied under Wilhelm Wundt for several years. Titchener is best known for creating his version of psychology that described the structure of the mind: structuralism. After becoming a professor at Cornell University, he created the largest doctoral program at that time in the United States. His first graduate student, Margaret Floy Washburn, became the first woman to be granted a PhD in psychology (1894).
Psychology is defined as "the scientific study of behavior and mental processes". Philosophical interest in the human mind and behavior dates back to the ancient civilizations of Egypt, Persia, Greece, China, and India.
A mental state, or a mental property, is a state of mind of a person. Mental states comprise a diverse class, including perception, pain/pleasure experience, belief, desire, intention, emotion, and memory. There is controversy concerning the exact definition of the term. According to epistemic approaches, the essential mark of mental states is that their subject has privileged epistemic access while others can only infer their existence from outward signs. Consciousness-based approaches hold that all mental states are either conscious themselves or stand in the right relation to conscious states. Intentionality-based approaches, on the other hand, see the power of minds to refer to objects and represent the world as the mark of the mental. According to functionalist approaches, mental states are defined in terms of their role in the causal network independent of their intrinsic properties. Some philosophers deny all the aforementioned approaches by holding that the term "mental" refers to a cluster of loosely related ideas without an underlying unifying feature shared by all. Various overlapping classifications of mental states have been proposed. Important distinctions group mental phenomena together according to whether they are sensory, propositional, intentional, conscious or occurrent. Sensory states involve sense impressions like visual perceptions or bodily pains. Propositional attitudes, like beliefs and desires, are relations a subject has to a proposition. The characteristic of intentional states is that they refer to or are about objects or states of affairs. Conscious states are part of the phenomenal experience while occurrent states are causally efficacious within the owner's mind, with or without consciousness. An influential classification of mental states is due to Franz Brentano, who argues that there are only three basic kinds: presentations, judgments, and phenomena of love and hate.
Mathematical psychology is an approach to psychological research that is based on mathematical modeling of perceptual, thought, cognitive and motor processes, and on the establishment of law-like rules that relate quantifiable stimulus characteristics with quantifiable behavior. The mathematical approach is used with the goal of deriving hypotheses that are more exact and thus yield stricter empirical validations. There are five major research areas in mathematical psychology: learning and memory, perception and psychophysics, choice and decision-making, language and thinking, and measurement and scaling.
Association of ideas, or mental association, is a process by which representations arise in consciousness, and also for a principle put forward by an important historical school of thinkers to account generally for the succession of mental phenomena. The term is now used mostly in the history of philosophy and of psychology. One idea was thought to follow another in consciousness if it were associated by some principle. The three commonly asserted principles of association were similarity, contiguity, and contrast, numerous others had been added by the nineteenth century. By the end of the nineteenth century physiological psychology was so altering the approach to this subject that much of the older associationist theory was rejected.
The adaptive unconscious, first coined by social psychologist Daniel Wegner in 2002, is described as a set of mental processes that is able to affect judgement and decision-making, but is out of reach of the conscious mind. It is thought to be adaptive as it helps to keep the organism alive. Architecturally, the adaptive unconscious is said to be unreachable because it is buried in an unknown part of the brain. This type of thinking evolved earlier than the conscious mind, enabling the mind to transform information and think in ways that enhance an organism's survival. It can be described as a quick sizing up of the world which interprets information and decides how to act very quickly and outside the conscious view. The adaptive unconscious is active in everyday activities such as learning new material, detecting patterns, and filtering information. It is also characterized by being unconscious, unintentional, uncontrollable, and efficient without requiring cognitive tools. Lacking the need for cognitive tools does not make the adaptive unconscious any less useful than the conscious mind as the adaptive unconscious allows for processes like memory formation, physical balancing, language, learning, and some emotional and personalities processes that includes judgement, decision making, impression formation, evaluations, and goal pursuing. Despite being useful, the series of processes of the adaptive unconscious will not always result in accurate or correct decisions by the organism. The adaptive unconscious is affected by things like emotional reaction, estimations, and experience and is thus inclined to stereotyping and schema which can lead to inaccuracy in decision making. The adaptive conscious does however help decision making to eliminate cognitive biases such as prejudice because of its lack of cognitive tools.
Oswald Külpe was a German structural psychologist of the late 19th and early 20th century. Külpe, who is lesser known than his German mentor, Wilhelm Wundt, revolutionized experimental psychology at his time. In his obituary, Aloys Fischer wrote that, “undoubtedly Külpe was the second founder of experimental psychology on German soil; for with every change of base he made it a requirement that an experimental laboratory should be provided.”
In psychology, mentalism refers to those branches of study that concentrate on perception and thought processes, for example: mental imagery, consciousness and cognition, as in cognitive psychology. The term mentalism has been used primarily by behaviorists who believe that scientific psychology should focus on the structure of causal relationships to reflexes and operant responses or on the functions of behavior.
Apperception is any of several aspects of perception and consciousness in such fields as psychology, philosophy and epistemology.
The Philosophy of mind is a branch of philosophy that deals with the nature of the mind and its relation to the body and the external world.
The metaphor "stream of consciousness" suggests how thoughts seem to flow through the conscious mind. Research studies have shown that humans only experience one mental event at a time as a fast-moving mind-stream. The term was coined by Alexander Bain in 1855 in the first edition of The Senses and the Intellect, when he wrote, "The concurrence of Sensations in one common stream of consciousness enables those of different senses to be associated as readily as the sensations of the same sense". But it is commonly credited to William James, who used it in 1890 in his The Principles of Psychology. The full range of thoughts—that one can be aware of—can form the content of this "stream".
Functional psychology or functionalism refers to a psychological school of thought that was a direct outgrowth of Darwinian thinking which focuses attention on the utility and purpose of behavior that has been modified over years of human existence. Edward L. Thorndike, best known for his experiments with trial-and-error learning, came to be known as the leader of the loosely defined movement. This movement arose in the U.S. in the late 19th century in direct contrast to Edward Titchener's structuralism, which focused on the contents of consciousness rather than the motives and ideals of human behavior. Functionalism denies the principle of introspection, which tends to investigate the inner workings of human thinking rather than understanding the biological processes of the human consciousness.
Peter Carruthers is a British-American philosopher and cognitive scientist working primarily in the area of philosophy of mind, though he has also made contributions to philosophy of language and ethics. He is a professor of philosophy at the University of Maryland, College Park, an associate member of Neuroscience and Cognitive Science Program, and a member of the Committee for Philosophy and the Sciences.
The introspection illusion is a cognitive bias in which people wrongly think they have direct insight into the origins of their mental states, while treating others' introspections as unreliable. The illusion has been examined in psychological experiments, and suggested as a basis for biases in how people compare themselves to others. These experiments have been interpreted as suggesting that, rather than offering direct access to the processes underlying mental states, introspection is a process of construction and inference, much as people indirectly infer others' mental states from their behaviour.
Die Seele: Ihr Verhältnis zum Bewusstsein und zum Leibe is a book by the German philosopher and psychologist Joseph Geyser was published in the journal "Wissen und Forschen " in 1914.
