Unconscious Cognition
Unconscious cognition is the processing of perception, memory, learning, thought, and language without being aware of it. The role of the unconscious mind on decision making is a topic greatly debated by neuroscientists, linguists, philosophers, and psychologists around the world. Though the actual level of involvement of the unconscious brain during a cognitive process might still be a matter of differential opinion, the fact that the unconscious brain does play a role in cognitive activity is undeniable. Several experiments and well recorded phenomena attest to this fact, for example the illusion-of-truth effect. There have also been several experiments suggesting that the unconscious mind might actually be better at decision making than the conscious mind when there are multiple variables to take into consideration. History The attitude of the scientific community towards the unconscious mind has undergone a drastic change from being viewed as a lazy reservoir of memories a ...

Unconscious Mind
The unconscious mind (or the unconscious) consists of the processes in the mind which occur automatically and are not available to introspection and include thought processes, memories, interests, and motivations. Even though these processes exist well under the surface of conscious awareness, they are theorized to exert an effect on behavior. The term was coined by the German Romantic philosopher Friedrich Schelling and later introduced into English by the poet and essayist Samuel Taylor Coleridge.Christopher John Murray, ''Encyclopedia of the Romantic Era, 1760-1850'' (Taylor & Francis, 2004: ), pp. 1001–1002. Empirical evidence suggests that unconscious phenomena include repressed feelings, automatic skills, subliminal perceptions, and automatic reactions, and possibly also Complex (psychology), complexes, hidden phobias, and desires. The concept was popularized by the Austrian neurologist and Psychoanalysis, psychoanalyst Sigmund Freud. In psychoanalytic theory#The uncon ...

Optical Illusions
Within visual perception, an optical illusion (also called a visual illusion) is an illusion caused by the visual system and characterized by a visual percept that arguably appears to differ from reality. Illusions come in a wide variety; their categorization is difficult because the underlying cause is often not clear but a classification proposed by Richard Gregory is useful as an orientation. According to that, there are three main classes: physical, physiological, and cognitive illusions, and in each class there are four kinds: Ambiguities, distortions, paradoxes, and fictions. A classical example for a physical distortion would be the apparent bending of a stick half immerged in water; an example for a physiological paradox is the motion aftereffect (where, despite movement, position remains unchanged). An example for a physiological fiction is an afterimage. Three typical cognitive distortions are the Ponzo, Poggendorff, and Müller-Lyer illusion. Physical illusions are ...

Subliminal Stimuli
Subliminal stimuli (; the prefix ' literally means "below" or "less than") are any sensory stimuli below an individual's threshold for conscious perception, in contrast to stimuli (above threshold). A 2012 review of functional magnetic resonance imaging (fMRI) studies showed that subliminal stimuli activate specific regions of the brain despite participants' unawareness. Visual stimuli may be quickly flashed before an individual can process them, or flashed and then masked to interrupt processing. Audio stimuli may be played below audible volumes or masked by other stimuli. Effectiveness Applications of subliminal stimuli are often based on the persuasiveness of a message. Research on action priming has shown that subliminal stimuli can only trigger actions a receiver of the message plans to perform anyway. However, consensus of subliminal messaging remains unsubstantiated by other research. Most actions can be triggered subliminally only if the person is already prepared to per ...

Implicit Learning
Implicit learning is the learning of complex information in an unintentional manner, without awareness of what has been learned. According to Frensch and Rünger (2003) the general definition of implicit learning is still subject to some controversy, although the topic has had some significant developments since the 1960s. Implicit learning may require a certain minimal amount of attention and may depend on attentional and working memory mechanisms. The result of implicit learning is implicit knowledge in the form of abstract (but possibly instantiated) representations rather than verbatim or aggregate representations, and scholars have drawn similarities between implicit learning and implicit memory. Examples from daily life, like learning how to ride a bicycle or how to swim, are cited as demonstrations of the nature of implicit learning and its mechanism. It has been claimed that implicit learning differs from explicit learning by the absence of consciously accessible knowledge. ...

Pre-attentive Processing
Pre-attentive processing is the subconscious accumulation of information from the environment.Atienza, M., Cantero, J. L., & Escera, C. (2001). Auditory information processing during human sleep as revealed by event-related brain potentials. Clinical Neurophysiology, 112(11), 2031-2045.Van der Heijden, A. H. C. (1996). Perception for selection, selection for action, and action for perception. Visual Cognition, 3(4), 357-361. All available information is pre-attentively processed. Then, the brain filters and processes what is important. Information that has the highest salience (a stimulus that stands out the most) or relevance to what a person is thinking about is selected for further and more complete analysis by conscious (attentive) processing. Understanding how pre-attentive processing works is useful in advertising, in education, and for prediction of cognitive ability.

Nepotism
Nepotism is an advantage, privilege, or position that is granted to relatives and friends in an occupation or field. These fields may include but are not limited to, business, politics, academia, entertainment, sports, fitness, religion, and other activities. The term originated with the assignment of nephews to important positions by Catholic popes and bishops. Nepotism has been criticized since the ancient times by several philosophers, including Aristotle, Valluvar, and Confucius, condemning it as both evil and unwise. Origins The term comes from Italian word ''nepotismo'',"Nepotism." Dictionary.com. Retrieved 20 June 2013. which is based on Latin root ''nepos'' meaning nephew. Since the an ...

Implicit Attitude
Implicit attitudes are evaluations that occur without conscious awareness towards an attitude object or the self. These evaluations are generally either favorable or unfavorable and come about from various influences in the individual experience. The commonly used definition of implicit attitude within cognitive and social psychology comes from Anthony Greenwald and Mahzarin Banaji's template for definitions of terms related to implicit cognition: "Implicit attitudes are introspectively unidentified (or inaccurately identified) traces of past experience that mediate favorable or unfavorable feeling, thought, or action toward social objects". These thoughts, feelings or actions have an influence on behavior that the individual may not be aware of. An attitude is differentiated from the concept of a stereotype in that it functions as a broad favorable or unfavorable characteristic towards a social object, whereas a stereotype is a set of favorable and/or unfavorable characteristi ...

Grammar
In linguistics, the grammar of a natural language is its set of structure, structural constraints on speakers' or writers' composition of clause (linguistics), clauses, phrases, and words. The term can also refer to the study of such constraints, a field that includes domains such as phonology, morphology (linguistics), morphology, and syntax, often complemented by phonetics, semantics, and pragmatics. There are currently two different approaches to the study of grammar: traditional grammar and Grammar#Theoretical frameworks, theoretical grammar. Fluency, Fluent speakers of a variety (linguistics), language variety or ''lect'' have effectively internalized these constraints, the vast majority of which – at least in the case of one's First language, native language(s) – are language acquisition, acquired not by conscious study or language teaching, instruction but by hearing other speakers. Much of this internalization occurs during early childhood; learning a language later ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
