Unconscious mind in the context of Introspection

The mind is that which thinks, feels, perceives, imagines, remembers, and wills. It covers the totality of mental phenomena, including both conscious processes, through which an individual is aware of external and internal circumstances, and unconscious processes, which can influence an individual without intention or awareness. The mind plays a central role in most aspects of human life, but its exact nature is disputed. Some characterizations focus on internal aspects, saying that the mind transforms information and is not directly accessible to outside observers. Others stress its relation to outward conduct, understanding mental phenomena as dispositions to engage in observable behavior.

The mind–body problem is the challenge of explaining the relation between matter and mind. Traditionally, mind and matter were often thought of as distinct substances that could exist independently from one another. The dominant philosophical position since the 20th century has been physicalism, which says that everything is material, meaning that minds are certain aspects or features of some material objects. The evolutionary history of the mind is tied to the development of nervous systems, which led to the formation of brains. As brains became more complex, the number and capacity of mental functions increased with particular brain areas dedicated to specific mental functions. Individual human minds also develop over time as they learn from experience and pass through psychological stages in the process of aging. Some people are affected by mental disorders, in which certain mental capacities do not function as they should.

Psychology is the scientific study of behavior and mind. Its subject matter includes the behavior of humans and nonhumans, both conscious and unconscious phenomena, and mental processes such as thoughts, feelings, and motives. Psychology is an academic discipline of immense scope, crossing the boundaries between the natural and social sciences. Biological psychologists seek an understanding of the emergent properties of brains, linking the discipline to neuroscience. As social scientists, psychologists aim to understand the behavior of individuals and groups.

A professional practitioner or researcher involved in the discipline is called a psychologist. Some psychologists can also be classified as behavioral or cognitive scientists. Some psychologists attempt to understand the role of mental functions in individual and social behavior. Others explore the physiological and neurobiological processes that underlie cognitive functions and behaviors.

Cognitions are mental activities that deal with knowledge. They encompass psychological processes that acquire, store, retrieve, transform, or otherwise use information. Cognitions are a pervasive part of mental life, helping individuals understand and interact with the world.

Cognitive processes are typically categorized by their function. Perception organizes sensory information about the world, interpreting physical stimuli, such as light and sound, to construct a coherent experience of objects and events. Attention prioritizes specific aspects while filtering out irrelevant information. Memory is the ability to retain, store, and retrieve information, including working memory and long-term memory. Thinking encompasses psychological activities in which concepts, ideas, and mental representations are considered and manipulated. It includes reasoning, concept formation, problem-solving, and decision-making. Many cognitive activities deal with language, including language acquisition, comprehension, and production. Metacognition involves knowledge about knowledge or mental processes that monitor and regulate other mental processes. Classifications also distinguish between conscious and unconscious processes and between controlled and automatic ones.

Paralanguage, also known as vocalics, is a component of meta-communication that may modify meaning, give nuanced meaning, or convey emotion, by using suprasegmental techniques such as prosody, including pitch, volume, intonation, etc. It is sometimes defined as relating to nonphonemic properties only. Paralanguage may be expressed consciously or unconsciously.

The study of paralanguage is known as paralinguistics and was invented by George L. Trager in the 1950s, while he was working at the Foreign Service Institute of the U.S. Department of State. His colleagues at the time included Henry Lee Smith, Charles F. Hockett (working with him on using descriptive linguistics as a model for paralanguage), Edward T. Hall developing proxemics, and Ray Birdwhistell developing kinesics. Trager published his conclusions in 1958, 1960 and 1961.

Surrealism is an art and cultural movement that developed in Europe in the aftermath of World War I in which artists aimed to allow the unconscious mind to express itself, often resulting in the depiction of illogical or dreamlike scenes and ideas. Its intention was, according to leader André Breton, to "resolve the previously contradictory conditions of dream and reality into an absolute reality, a super-reality", or surreality. It produced works of painting, writing, photography, theatre, filmmaking, music, comedy and other media as well.

Works of Surrealism feature the element of surprise, unexpected juxtapositions and non sequitur. However, many Surrealist artists and writers regard their work as an expression of the philosophical movement first and foremost (for instance, of the "pure psychic automatism" Breton speaks of in the first Surrealist Manifesto), with the works themselves being secondary, i.e., artifacts of surrealist experimentation. Leader Breton was explicit in his assertion that Surrealism was, above all, a revolutionary movement. At the time, the movement was associated with political causes such as communism and anarchism. It was influenced by the Dada movement of the 1910s.

Psychoanalysis is a set of theories and techniques of research to discover unconscious processes and their influence on conscious thought, emotion and behavior. Based on dream interpretation, psychoanalysis is also a talk therapy method for treating mental disorders. Established in the early 1890s by Sigmund Freud, it takes into account Darwin's theory of evolution, neurology findings, ethnology reports, and, in some respects, the clinical research of his mentor Josef Breuer. Freud developed and refined the theory and practice of psychoanalysis until his death in 1939. In an encyclopedic article, he identified its four cornerstones: "the assumption that there are unconscious mental processes, the recognition of the theory of repression and resistance, the appreciation of the importance of sexuality and of the Oedipus complex."

Freud's earlier colleagues Alfred Adler and Carl Jung soon developed their own methods (individual and analytical psychology); he criticized these concepts, stating that they were not forms of psychoanalysis. After the author's death, neo-Freudian thinkers like Erich Fromm, Karen Horney and Harry Stack Sullivan created some subfields. Jacques Lacan, whose work is often referred to as Return to Freud, described his metapsychology as a technical elaboration of the three-instance model of the psyche and examined the language-like structure of the unconscious.

The psyche /ˈsaɪki/ is currently used to describe the totality of the human mind, conscious and unconscious. Especially in older texts, the English word soul is sometimes used synonymously.

Psychology is the scientific or objective study of the psyche. The word has a long history of use in psychology and philosophy, dating back to ancient times, and represents one of the fundamental concepts for understanding human nature from a scientific point of view.

Anti-Oedipus: Capitalism and Schizophrenia (French: Capitalisme et schizophrénie. L'anti-Œdipe) is a 1972 book by French authors Gilles Deleuze and Félix Guattari, the former a philosopher and the latter a psychoanalyst. It is the first volume of their collaborative work Capitalism and Schizophrenia, the second being A Thousand Plateaus (1980).

In the book, Deleuze and Guattari developed the concepts and theories in schizoanalysis, a loose critical practice initiated from the standpoint of schizophrenia and psychosis as well as from the social progress that capitalism has spurred. They refer to psychoanalysis, economics, the creative arts, literature, anthropology and history in engagement with these concepts. Contrary to contemporary French uses of the ideas of Sigmund Freud, they outlined a "materialist psychiatry" modeled on the unconscious regarded as an aggregate of productive processes of desire, incorporating their concept of desiring-production which interrelates desiring-machines and bodies without organs, and repurpose Karl Marx's historical materialism to detail their different organizations of social production, "recording surfaces", coding, territorialization and the act of "inscription". Friedrich Nietzsche's ideas of the will to power and eternal recurrence also have roles in how Deleuze and Guattari describe schizophrenia; the book extends from much of Deleuze's prior thinking in Difference and Repetition and The Logic of Sense that utilized Nietzsche's ideas to explore a radical conception of becoming.

In analytical psychology, the shadow (also known as ego-dystonic complex, repressed id, shadow aspect, or shadow archetype) is an unconscious aspect of the personality that does not correspond with the ego ideal, leading the ego to resist and project the shadow, creating conflict with it. The shadow may be personified as archetypes which relate to the collective unconscious, such as the trickster.

Surreal humour (also called surreal comedy, absurdist humour, or absurdist comedy) is a form of humour predicated on deliberate violations of causal reasoning, thus producing events and behaviours that are obviously illogical. Portrayals of surreal humour tend to involve bizarre juxtapositions, incongruity, non-sequiturs, irrational or absurd situations, and expressions of nonsense.

Surreal humour grew out of surrealism, a cultural movement developed in the 20th century by French and Belgian artists, who depicted unnerving and illogical scenes while developing techniques to allow the unconscious mind to express itself. The movement itself was foreshadowed by English writers in the 19th century, most notably Lewis Carroll and Edward Lear. The humour in surreal comedy arises from a subversion of audience expectations, emphasising the ridiculousness and unlikeliness of a situation, so that amusement is founded on an unpredictability that is separate from a logical analysis of the situation.

Automatism is a set of brief unconscious or automatic behaviors, typically at least several seconds or minutes, while the subject is unaware of actions. This type of automatic behavior often occurs in certain types of epilepsy, such as complex partial seizures in those with temporal lobe epilepsy, or as a side effect of particular medications such as zolpidem.

Automatic behaviors involve the spontaneous production of purposeless verbal or motor behavior without conscious self-control or self-censorship. This condition can be observed in a variety of contexts, including schizophrenia, dissociative fugue, Tourette syndrome, epilepsy (in complex partial seizures and Jacksonian seizures), narcolepsy, or in response to a traumatic event.
