Cognition is the scientific term for "the process of thought." Usage of the term varies in different disciplines; for example in psychology and cognitive science, it usually refers to an information processing view of an individual's psychological functions. Other interpretations of the meaning of cognition link it to the development of concepts; individual minds, groups, and organizations.

[edit] Introduction
The term cognition (Latin: cognoscere, "to know", "to conceptualize" or "to recognize") refers to a faculty for the processing of information, applying knowledge, and changing preferences. Cognition, or cognitive processes, can be natural or artificial, conscious or unconscious. These processes are analyzed from different perspectives within different contexts, notably in the fields of linguistics, anesthesia, neurology, psychology, philosophy, anthropology, systemics and computer science. Within psychology or philosophy, the concept of cognition is closely related to abstract concepts such as mind, reasoning, perception, intelligence, learning, and many others that describe capabilities of the mind. In psychology and in artificial intelligence, cognition is used to refer to the mental functions, mental processes (thoughts) and states of intelligent entities (humans, human organizations, highly autonomous machines).
[edit] Psychology
The sort of mental processes described as cognitive are largely influenced by research which has successfully used this paradigm in the past, likely starting with Thomas Aquinas, who divided the study of behavior into two broad categories: cognitive (how we know the world), and affect (feelings and emotions). Consequently, this description tends to apply to processes such as memory, association, concept formation, language, attention, perception, action, problem solving and mental imagery.[1] Traditionally, emotion was not thought of as a cognitive process. This division is now regarded as largely artificial, and much research is currently being undertaken to examine the cognitive psychology of emotion; research also includes one's awareness of strategies and methods of cognition, known as metacognition.
Empirical research into cognition is usually scientific and quantitative, or involves creating models to describe or explain certain behaviors.
While few people would deny that cognitive processes are a function of the brain, a cognitive theory will not necessarily make reference to the brain or other biological process (compare neurocognitive). It may purely describe behavior in terms of information flow or function. Relatively recent fields of study such as cognitive science and neuropsychology aim to bridge this gap, using cognitive paradigms to understand how the brain implements these information-processing functions (see also cognitive neuroscience), or how pure information-processing systems (e.g., computers) can simulate cognition (see also artificial intelligence). The branch of psychology that studies brain injury to infer normal cognitive function is called cognitive neuropsychology. The links of cognition to evolutionary demands are studied through the investigation of animal cognition. And conversely, evolutionary-based perspectives can inform hypotheses about cognitive functional systems evolutionary psychology.
The theoretical school of thought derived frome cognitive approach is often called cognitivism.
The phenomenal success of the cognitive approach can be seen by its current dominance as the core model in contemporary psychology (usurping behaviorism in the late 1950s).
[edit] Cognition as social process
It has been observed since antiquity that language acquisition in human children fails to emerge unless the children are exposed to language. Thus, language acquisition is an example of an emergent behavior. In this case, the individual is made up of a set of mechanisms "expecting" such input from the social world.
In education, for instance, which has the explicit task in society of developing child cognition, choices are made regarding the environment and permitted action that lead to a formed experience. In social cognition, face perception in human babies emerges by the age of two months. This is in turn affected by the risk or cost of providing these, for instance, those associated with a playground or swimming pool or field trip. On the other hand, the macro-choices made by the teachers are extremely influential on the micro-choices made by children.
In a large systemic perspective, cognition is considered closely related to the social and human organization functioning and constrains. Managerial decision making processes can be erroneous in politics, economy and industry for the reason of different reciprocally dependent socio-cognitive factors. This domain became the field of interest of emergent socio-cognitive engineering.

| NIH-sponsored research yields promising malaria drug candidate |
|
A chemical that rid mice of malaria-causing parasites after a single oral dose
may eventually become a new malaria drug if further tests in animals and people
uphold the promise of early findings. The compound, NITD609, was developed by
an international team of researchers including Elizabeth A. Winzeler, Ph.D.,
a grantee of the National Institute of Allergy and Infectious Diseases (NIAID),
part of the National Institutes of Health.

| Lower blood pressure goal benefits African-Americans with chronic kidney disease, protein in the urine |
|
On average, a lower blood pressure goal was no better than the standard blood pressure goal at slowing progression of kidney disease among African-Americans who had chronic kidney disease resulting from high blood pressure, according to results of the African-American Study of Kidney Disease and Hypertension (AASK), the largest and longest study of chronic kidney disease (CKD) in African-Americans. However, the blood pressure goal did benefit people who also had protein in the urine, which is a sign of kidney damage. The study, funded by the National Institutes of Health, appears in the Sept. 2 issue of the New England Journal of Medicine.

| New TB Diagnostic Proves Effective, Expedient, Study Finds |
|
A molecular test designed to easily diagnose tuberculosis (TB) and detect a drug-resistant form of the bacterium that causes TB can provide much more specific, sensitive and rapid results than currently available TB diagnostics, according to a new study in the New England Journal of Medicine. In a test involving 1,730 patients with suspected drug-sensitive or multidrug-resistant pulmonary TB, the Xpert MTB/RIF TB test successfully identified 98 percent of all confirmed TB cases and 98 percent of patients with rifampin-resistant bacteria in less than two hours.

|
The National Institutes of Health announced today that it has awarded the first new grants under the Biomedical Research on the International Space Station (BioMed-ISS) initiative, a collaborative effort between NIH and NASA. Using a special microgravity environment that Earth-based laboratories cannot replicate, researchers will explore fundamental questions about important health issues, such as how bones and the immune system get weak.

Researchers at the National Institutes of Health and other institutions have found that exposure to lead in childhood may delay the onset of puberty in young girls, with higher doses increasing the chance for later maturation.
