Conscious vs. To what degree are individuals aware of the information that they are processing at any given moment? If individuals are unaware of these processes, then are they able to control their behaviors? Research suggests that both conscious and unconscious processes exert influences on behaviors. This entry will provide a brief overview of unconscious and conscious processes including the connections these processes have with an array of outcomes.

The four postulates of Freudian unconscious neurocognitive convergences

For several reasons, the two approaches to unconscious are generally conceived as irreducible. Nowadays, we are witnessing a certain convergence between both fields. The aim of this paper consists in examining the four basic postulates of Freudian unconscious at the light of neurocognitive sciences. They posit: 1 that some psychological processes are unconsciously performed and causally determine conscious processes, 2 that they are governed by their own cognitive rules, 3 that they set out their own intentions, 4 and that they lead to a conflicting organization of psyche.

We show that each of these postulates is the subject of empirical and theoretical works. If the two fields refer to more or less similar mechanisms, we propose that their opposition rests on an epistemological misunderstanding. As a conclusion, we promote a conservative reunification of the two perspectives. The following discussion is representative of a larger pattern in the non dialog between psychoanalysis and neuro-biology: Edelman , in Bright Air, Brilliant Fire , described the conversation he used to have with Jacques Monod on Freud.

They are all conscious. Everything that Freud said applies to me, and none of it to you. Both Edelman and Jacob are materialists, at least naturalists. Moreover, if the two biologists share a more or less similar brain, can they have two different kinds of unconscious; among which only one the cognitive one is scientifically observable? The aim of this article is to review out the empirical and theoretical convergences between the two fields pleading in favor of a common and objective representation of unconscious processes see Table 1.

Table 1. Labels attached to unconscious ucs in the neurocognitive literature, aligned on the four postulates of Freudian unconscious. Some researchers have already attempted to consider Freudian hypotheses at the light of cognitive science and neuroscience Figure 1.

Among them, Shevrin and Dickman , in a seminal paper, started out from the common consensus that defines unconscious processes are 1 psychological events that are unknown to the patient but that actively affect its behavior, and adduced empirical data in favor of the more challenging Freudian postulate that 2 unconscious processes are ruled by specific laws of organization.

We find this strategy — which take the basic Freudian postulates as suggestions to progressively define and evaluate unconscious life — to be extremely helpful. Thus, along the same lines, we first review cognitive and neuroscience data in favor of the first two postulates, and then we propose two others postulates to round out the Freudian paradigm: 3 the unconscious processes are goal directed; and 4 the unconscious processes are conflicting.

In conclusion we propose that current experimental and theoretical works reveal that the opposition between Freudian and cognitive unconscious rests on a methodological misunderstanding.

One of the first and most persistent criticisms of Freud is that the existence of unconscious representations is self-contradictory. Some philosophers still object to such talk, on the basis of the supposition that representation is by nature conscious Searle, Recently, psychologists Greenwald, ; Loftus and Klinger, have posed this question in terms of whether the unconscious is smart or dumb.

The philosopher Dennett claims that psychological representations are not mental entities coded in cognitive or biological systems Dennett, They refer to psychological descriptions cuing biological regulation traits, which are not psychological per se.

As a matter of fact we have only indirect experience of a psychological unconscious, inferred from overt behaviors. But the question now is whether those heuristic concepts, applied to the unconscious, are consistent with neurocognitive data. Brain imaging has shown that many subliminal stimuli activate brain regions without the subject being able to report those influences. For example, Whalen et al. Respondents were then asked about the human facial expressions and did not report seeing the fearful or happy faces.

Hence, there is reason to think that affective stimuli can cause effects on the subliminal level, and certain stimuli — say, fearful faces — are more intensely received than other ones.

This in itself indicates some primitive hierarchizing organization. But how complex is that organization? Are emotional effects too simple for unconscious processes to be called smart, that is, to make discriminations based on an autonomously produced structure?

The study of patients with brain damage has brought out evidence about even more complex unconscious processes. Patients with damage to primary visual cortex are able to make accurate pointing movements toward object they report not seeing. The classic research of Goodale and Milner has reported that while blind sight subjects consciously express impairment in finding and seeing mobile slots, they still succeed in posting a card in it.

Hence, unconscious visual perception is able not only to deal with basic one-dimensional images, but also with three-dimensional data like shape, orientation, size, etc. These results are in line with the hypothesis of two visual neural pathways by Ungerleider and Mishkin : the ventral one processing conscious representations allowing object identification and the dorsal one, unconsciously analyzing the visual field in a pragmatic way.

The work of Goodale and Milner and the two visual pathways hypothesis not only show the material mechanism by which unconscious processing of complex representations occurs, but do so in maintaining a clear-cut distinction between upper and higher processing levels. Marshall and Halligan have proceeded further in the realm of higher-level processing. They chose for their experiment a patient who suffered from lesions on the right side of the brain, which was expressed in unilateral neglect, a condition in which the patient turns away from, forgets or ignores objects in the contralesional space.

To test the cognitive processing of unimpaired sensorimotor inputs, a patient with unilateral neglect was presented with two line drawings of a house, one above the other. Sometimes they were identical, and sometimes one of the houses was on fire.

When the flames came from the right hand side of the house, she correctly identified whether the pictures were the same or different. When the flames came from the left hand side of the house, however the other house was not on fire, she identified them as the same.

Two conclusions can be drawn. Second, it seems that the differences between unconscious and conscious processes are not strictly determined by anatomical and hierarchical reasons.

Thus, from the functional point of view, the richness of unconscious processes may stem from their capacities to perform the tasks usually taken as necessitating consciousness. Postulating the existence of unconscious processes supposes admitting psychic continuity and determinism. It means that psychological discontinuities — displayed by symptoms, parapraxes, gaps, and so forth — can be explained by unconscious causes.

As Shevrin et al. The reason that response latency increases is that the consciousness must necessarily repress the automatic semantic analysis of the word. Numerous studies have confirmed these unconscious causal effects, especially those investigating subliminal effects. Priming is defined as a non-conscious form of memory that involves a change in the ability to identify, produce, or classify an item as a result of a previous encounter with it.

For example, pictures of smiling or scowling faces were subliminally presented to subjects prior to the task of rating the attractiveness of Chinese ideographs. Not only the affective values of priming had effects on the choice of the targets, but also suboptimal stimulations impacted judgments differently than optimal ones. In contrast, optimal ones induced cognitive constraints that permitted directing affective priming onto specific targets.

The limited precision of unconscious affects is paralleled by the limitation of unconscious cognitive capacities. For instance, Sperling presented subjects a brief flash of 12 letters. The subjects succeeded in reporting a limited number of them on average, about five. As a matter of fact, all the items had to be unconsciously represented before being selected. It is noteworthy that measurements show that the longer the time between the exposure and the report is important, the weaker are the subjects to report the items they have seen.

Thus, the non-selected items have vanished from memory during the remembering task. From those limited memorial capacities, we can conclude that if unconscious processes are not dumb, it is even too optimistic to endow them with full intelligence 2. Nevertheless, one can ask whether those studies are methodologically consistent with the way Freud theorized in terms of unconscious processes.

On the other hand, one may ask whether the subliminal paradigm, as it is commonly used, is adequate to evaluate the Freudian theory especially as it insists on endogenous motives linked with an idiosyncratic inner life Arminjon et al. Such questions are difficult to answer empirically, principally because of the methodological difficulties one encounters when trying to set up experiments on subjectivity. Meta-analysis has shown the effect to be reproducible, but the reasons why are still challenged Hardaway, ; Weinberger and Hardaway, Numerous researchers have claimed such phrases to be far too complex for unconscious cognition.

For instance, Greenwald and Liu and Draine have shown two-word grammatical combinations to be beyond the analytic powers of unconscious cognition. Nevertheless, other phrases have been tested and have never displayed such effect Greenwald, It is noteworthy that, in this study, the stimulus is not idiosyncratic. Yet, its universal affective valence might compensate for its generality. If the unconscious seems to be limited in processing complex representations, we might ask whether affective idiosyncratic values influence, for instance, the number of items one can retrieve.

This epistemological point emphasizes that we cannot infer unconscious is dumb from its incapacity to perform what we do consciously. In others words, one of the most important Freudian contribution consists in having apprehended unconscious per se and not such as the strict negation of consciousness. Here, one finds a dimension for research in which the psychoanalytical insistence on subjective conditions of stimuli perception might inspire cognitive sciences.

The analysis of the first postulate has produced evidence of particularities of unconscious and conscious processes from numerous psychological studies. A rule of thumb is that unconscious processes are more sensitive to affective stimuli, whereas conscious processes involve more complex representational processing. Thus, each seems to display a specific kind of functioning. The theory states that some aspects of the Id may become conscious, while some of the ego may be unconscious.

Thus, the shift from reducing unconscious determinants to the sole repressed representations to a descriptive cognitive topology has left open room for a plurality of unconscious processes including the cognitive one? According to Carhart-Harris and Friston the Id overlaps the characteristics Freud attributed to unconscious system. However, the Id might nominate a system subserving a specific mode of cognition, more than a psychic region or apparatus. In the following section we aim to show how such a perspective leads unconscious processes to be understood as an alternative type of cognition better than a weakened one.

Given the observations he made in his clinical practice, Freud theorized that psychosis, dreams, and free associations reveal a mode of cognition ordinarily suppressed or inhibited. The sovereign principle is … that of obtaining pleasure. This brings up the question: what are the current reasons for postulating two separate mode of cognition? An interesting experiment addressing this question has been performed by Shevrin et al. In spite of being only based on subliminal and supraliminal stimulations, authors have respected the Freudian paradigm in working around the limits encoded in the protocols of normal psychological experiments, which are generally and intentionally blind to the individual differences that are claimed as determinants in psychoanalytical clinical work.

Shevrin and his associates tried to test the power of idiosyncratic stimuli while working on subliminal perception, generally using universal emotional ones i. They have constituted lists of affect-laden words selected by clinicians on the basis of extensive interviews of patients. The results show different patterns of responses triggered by subliminal and supraliminal exposure Figure 2.

The unconscious conflict words presented subliminally showed a specific time—frequency pattern — high frequencies appear before lower ones — the conscious conflict words presented supraliminally, displayed a reverse pattern.

Freud and the Unconscious Mind

By Dr. Saul McLeod , published , updated Sigmund Freud didn't exactly invent the idea of the conscious versus unconscious mind, but he certainly was responsible for making it popular and this was one of his main contributions to psychology. Freud used the analogy of an iceberg to describe the three levels of the mind. Freud described the conscious mind, which consists of all the mental processes of which we are aware, and this is seen as the tip of the iceberg. For example, you may be feeling thirsty at this moment and decide to get a drink. The preconscious contains thoughts and feelings that a person is not currently aware of, but which can easily be brought to consciousness

Sigmund Freud, the father of psychoanalysis, was a physiologist, medical doctor, psychologist and influential thinker of the early twentieth century. Working initially in close collaboration with Joseph Breuer, Freud elaborated the theory that the mind is a complex energy-system, the structural investigation of which is the proper province of psychology. Freud was born in Frieberg, Moravia in , but when he was four years old his family moved to Vienna where he was to live and work until the last years of his life. He always considered himself first and foremost a scientist, endeavoring to extend the compass of human knowledge, and to this end rather than to the practice of medicine he enrolled at the medical school at the University of Vienna in He received his medical degree in , and having become engaged to be married in , he rather reluctantly took up more secure and financially rewarding work as a doctor at Vienna General Hospital. Shortly after his marriage in , which was extremely happy and gave Freud six children—the youngest of whom, Anna, was to herself become a distinguished psychoanalyst—Freud set up a private practice in the treatment of psychological disorders, which gave him much of the clinical material that he based his theories and pioneering techniques on.

Consciousness is the quality or state of being aware of an external object or something within oneself, such as thoughts, feelings, memories, or sensations. It has also been defined in the following ways: sentience, awareness, subjectivity, the ability to experience or to feel, wakefulness, having a sense of selfhood, and the executive-control system of the mind. At one time, consciousness was viewed with skepticism by many scientists, but in recent years, it has become a significant topic of research in psychology and neuroscience. Despite the difficulty in coming to a definition, many philosophers believe that there is a broadly shared underlying intuition about what consciousness is. Philosophers since the time of Descartes and Locke have struggled to comprehend the nature of consciousness and pin down its essential properties. Issues of concern in the philosophy of consciousness include the following: whether consciousness can ever be explained mechanistically; whether non-human consciousness exists, and if so, how it can be recognized; how consciousness relates to language; whether consciousness can be understood in a way that does not require a dualistic distinction between mental and physical states or properties; and whether it may ever be possible for computers or robots to be conscious.


becoming conscious. We then say of the idea that it is in a state of unconsciousness," of being not apprehended by the conscious mind, and we can produce.


Sigmund Freud (1856—1939)

Freud used this term to make clear that the repressed is a part of the unconscious , not all of it, which is to say that the repressed does not comprise the whole unconscious. Many facts, memories, etc. The preconscious refers to those facts of which we are not currently conscious but which exist in latency and can be easily called up when needed.

Freud's psychoanalytic theories

Sigmund Freud 6 May — 23 September is considered to be the founder of the psychodynamic approach to psychology , which looks to unconscious drives to explain human behavior. Freud believed that the mind is responsible for both conscious and unconscious decisions that it makes on the basis of psychological drives.

In order to understand Freud's theory, it is essential to first understand what he believed each part of personality did, how it operated, and how these three elements interact to contribute to the human experience. Each level of awareness has a role to play in shaping human behavior and thought. Freud delineated the mind in the distinct levels, each with their own roles and functions. Freud likened the three levels of mind to an iceberg. The top of the iceberg that you can see above the water represents the conscious mind.
