Saul McLeodpublishedupdated 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.
History[ edit ] The attitude of the scientific community towards the unconscious mind has undergone a drastic change from being viewed as a lazy reservoir of memories and non-task oriented behavior to being regarded as an active and essential component in the processes of decision making.
Historically, the unconscious mind has been viewed as the source of dreams, implicit memory which allows people to walk or ride a bicycle without consciously thinking about the activityand the storing place for memories.
But new insight revealing that the unconscious brain might also be an active player in decision making, problem solving, creative writing and critical thinking have revolutionized the predominant view of the importance of the unconscious on cognitive processes. One familiar example of the operation of the unconscious in problem solving is a well-known phenomenon of having a "Eureka!
Currently, several experiments are being performed to measure the extent of unconscious' influence on conscious thought.
Types of unconscious[ edit ] Freud's unconscious[ edit ] Sigmund Freud is perhaps the most well-known psychologist and his theories laid the foundation for the serious scientific investigation of the unconscious brain. Consciousness, according to Freud, was the center for perception whereas the unconscious was the storehouse of memories, desires, and needs.
According to Freud past thoughts and memories which are deleted from conscious thought are stored by the unconscious and these thoughts help direct the thoughts and feelings of an individual and influence their decision making processes. He believed that the personal unconscious held memories and experiences specific to every individual and the collective unconscious held memories, predispositions and experiences of a species which are passed on from generation to generation and The unconscious process shared among all the individuals of a species.
Lacan's linguistic unconscious[ edit ] Jacques Lacan in his psychoanalytical theory compared the structuring of the unconscious to the way a language is structured. According to his theory there is no reference to self thus making the unconscious a dynamic structure.
This suggests that unconscious influence on thought processes could be altered after traumatic brain injury. This theory could explain the cases of altered personality, like Phineas Gagedue to trauma or traumatic brain injury. Measurement[ edit ] To establish unconscious perception a demonstration of the absence of some critical stimulus is established and the effect of the same stimulus on behavior is tested.
To establish the absence of the stimulus, the degree to which a critical stimulus reaches conscious awareness is assessed, by testing whether a subject can acknowledge or perceive the presence of the stimulus.
This is called a direct measure D of processing, as the task requires some type of direct report on the perception of the critical stimulus from the subject.

Also, one must assess the degree to which the stimulus affects a certain behavior. This process is the indirect measure I as responses of something other than the critical stimulus is measured. In fact, it has now the status of a scientific paradigmbut criticism has started to fall upon it, with calls for a paradigm shift in the field.
The numerous examples of optical illusionshallucinations and other tricks that the unconscious brain plays on the conscious brain provide ample evidence of the active role of the unconscious mind during data gathering and analysis.
Several experiments have been performed to show that the unconscious brain is able to gather data at a much faster rate than the conscious brain and also that the unconscious brain filters out a great amount of information and can use this information to influence cognitive decision making processes.
Artificially induced scotomas[ edit ] Vilayanur S. Ramachandran in his research proved that the unconscious brain not only screens certain data from the conscious brain, rendering visual data inaccurate, but also is responsible for filling in false data in place of missing data in certain circumstances.
In his paper on "Perceptual filling in of artificially induced scotomas in human vision"  he records the effect of the unconscious brain filling in the blind spots in the human visual field. Subliminal Messages[ edit ] Subliminal messages also utilize the phenomenon of the unconscious brain processing messages faster than the conscious brain and also noticing data in a visual or auditory field that remain below the threshold of the conscious brain.
They can be quick clips inserted within another video or barely perceptible text inscribed in a picture. These messages flutter on the edge of perception and are almost impossible to notice unless and until one's conscious brain is called to pay attention to these minute details.
Modern day ads, posters and even shows and movies which are broadcast around the world use subliminal messages to unconsciously attract an individual or manipulate an individual to unconscious like a product or a show. Experiments were performed in which participants were asked to identify whether certain nonsensical and made up words belong to a group of words which they had been previously shown.
Some participants were not informed that the word sets were based on rules. This shows that it might not be necessary to be consciously aware of grammatical rules to know proper grammar.
This theory might explain the feeling we undergo when we feel that a certain sentence structure is awkward or wrong even though we might not be able to clearly define the reason why the sentence is incorrect.
Implicit egotism[ edit ] Implicit egotism refers to the unconscious tendency of people to prefer things that resemble the self.Sep 10, · In summary, the difference between conscious and unconscious processes (regardless of the appellations ascribed to each process) is an inescapable contrast that is encountered after even a cursory examination of mental and nervous phenomena 2.
The unconscious mind is still viewed by many psychological scientists as the shadow of a “real” conscious mind, though there now exists substantial evidence that the unconscious is not identifiably less flexible, complex, controlling, deliberative, or action-oriented than is its counterpart.
Whatever else suicide is, it is a conscious act, but on the other hand, the driving force is an unconscious process.
We know that in Jung's world, the undeveloped, unconscious portions of the personality which strive for integration in the wholeness of the individual, is the compensatory function of unconscious process, giving the psyche its teleological character. Finally, the unconscious mind comprises mental processes that are inaccessible to consciousness but that influence judgements, feelings, or behavior (Wilson, ).Author: Saul Mcleod.
Jul 04, · Alternative approaches to study unconscious influences on cognitive control. Under our suggestion that conscious and unconscious processes might share common mechanisms and differ mostly in terms of representation quality, unconscious processes would indeed be expected to influence control mechanisms, like their conscious counterparts do (Suhler and Churchland, ).
