In psychoanalytic terms, the unconscious does not include all that is not conscious, but rather what is actively repressed from conscious thought or what a person is averse to knowing consciously. Freud viewed the unconscious as a repository for socially unacceptable ideas, wishes or desires, traumatic memories, and painful emotions put out of mind by the mechanism of

. Seeing as these unconscious thoughts are normally cryptic, psychoanalysts are considered experts in interpreting their messages.
Freud based his concept of the unconscious on a variety of observations. For example, he considered "slips of the tongue" to be related to the unconscious in that they often appeared to show a person's true feelings on a subject. For example, "I decided to take a summer ''curse'' ". This example shows a slip of the word "course" where the speaker accidentally used the word "curse" which would ostensibly show that they have negative feelings about having to do this. Freud noticed that also his patients' dreams expressed important feelings they were unaware of. After these observations, he concluded that psychological disturbances are largely caused by personal conflicts existing at the unconscious level. His psychoanalytic theory acts to explain personality, motivation and mental disorders by focusing on
unconscious determinants of behavior.
Freud later used his notion of the unconscious in order to explain certain kinds of
neurotic behavior. The theory of the unconscious was substantially transformed by later psychiatrists, among them

Dreams
Freud
In terms of the unconscious, the purpose of dreams, as stated by Freud, is to fulfill repressed wishes through the process of dreaming, since they cannot be fulfilled in real life. For example, if someone were to rob a store and to feel guilty about it, they might dream about a scenario in which their actions were justified and renders them blameless. Freud asserted that the wish-fulfilling aspect of the dream may be disguised due to the difficulty in distinguishing between
manifest content and latent content. The manifest content consists of the plot of a dream at the surface level. The latent content refers to the hidden or disguised meaning of the events in the plot. The latent content of the dream is what supports the idea of wish fulfillment. It represents the intimate information in the dreamer's current issues and childhood conflict.

Contemporary cognitive psychology
Research
While, historically, the psychoanalytic research tradition was the first to focus on the phenomenon of unconscious mental activity, there is an extensive body of conclusive research and knowledge in contemporary cognitive psychology
Cognitive psychology is the scientific study of mental processes such as attention, language use, memory, perception, problem solving, creativity, and reasoning.

Most of that (cognitive) research on unconscious processes has been done in the mainstream, academic tradition of the information processing paradigm.

, the cognitive tradition of research on unconscious processes is based on relatively few theoretical assumptions and is very empirically oriented (i.e., it is mostly data driven). Cognitive research has revealed that automatically, and clearly outside of conscious awareness, individuals register and acquire more information than what they can consciously remember and report. It is unclear how much, if any, of these processes can be experienced: The overflow hypothesis suggests that we experience much more than what we can subsequently report. The sparse phenomenology hypothesis forms an opposing view.
Much research has focused on the differences between conscious and unconscious perception. There is evidence that whether something is consciously perceived depends both on the incoming stimulus (bottom up strength) and on top-down mechanisms like Attention
Attention is the behavioral and cognitive process of selectively concentrating on a discrete aspect of information, whether considered subjective or objective, while ignoring other perceivable information. William James (1890) wrote that "Atte ...

Unconscious processing of information about frequency
For example, an extensive line of research conducted by Hasher and Zacks has demonstrated that individuals register information about the frequency of events automatically (i.e., outside of conscious awareness and without engaging conscious information processing resources). Moreover, perceivers do this unintentionally, truly "automatically", regardless of the instructions they receive, and regardless of the information processing goals they have. The ability to unconsciously and relatively accurately tally the frequency of events appears to have little or no relation to the individual's age,[Connolly, Deborah Ann (1993). ]

contends that "The term 'the unconscious' is actually a mystification (even though one might use it for reasons of convenience, as I am guilty of doing in these pages). There is no such thing as ''the'' unconscious; there are only experiences of which we are aware, and others of which we are not aware, that is, ''of which we are unconscious''. If I hate a man because I am afraid of him, and if I am aware of my hate but not of my fear, we may say that my hate is conscious and that my fear is unconscious; still my fear does not lie in that mysterious place: 'the' unconscious."

has offered a critique of the Freudian unconscious. He argues that the Freudian cases of shallow, consciously held mental states would be best characterized as 'repressed consciousness,' while the idea of more deeply unconscious mental states is more problematic. He contends that the very notion of a collection of "thoughts" that exist in a privileged region of the mind such that they are ''in principle never accessible'' to conscious awareness, is incoherent. This is not to imply that there are not "nonconscious" processes that form the basis of much of conscious life. Rather, Searle simply claims that to posit the existence of something that is like a "thought" in every way except for the fact that no one can ever be aware of it (can never, indeed, "think" it) is an incoherent concept. To speak of "something" as a "thought" either implies that it is being thought by a thinker or that it could be thought by a thinker. Processes that are not causally related to the phenomenon called thinking are more appropriately called the nonconscious processes of the brain.

David Holmes examined sixty years of research about the Freudian concept of "repression" and concluded that there is no positive evidence for this concept. Given the lack of evidence for many Freudian hypotheses, some scientific researchers proposed the existence of unconscious mechanisms that are very different from the Freudian ones. They speak of a "cognitive unconscious" (John Kihlstrom

, many researchers have sought to strip the notion of the unconscious from its Freudian heritage, and alternative terms such as "implicit" or "automatic" have been used. These traditions emphasize the degree to which cognitive processing happens outside the scope of cognitive awareness, and show that things we are unaware of can nonetheless influence other cognitive processes as well as behavior. Active research traditions related to the unconscious include implicit memory (see priming
