Cognition
The term
cognition (
Latin:
cognoscere, "to know") is used in several loosely-related ways to refer to a facility for the human like processing of
information, applying knowledge and changing preferences ( see, for ex.
IPK cognitive architecture). Cognition/(cognitive processes) can be natural and artificial, conscious and not conscious, therefore they are analyzed from different perspectives and in different contexts, in neurology, psychology, philosophy,
systemics and
computer science. The concept cognition is closely related to such abstract concepts as, mind, reasoning, perception, intelligence, learning, and many others which describe numerous capabilities of human mind and expected properties of artificial or synthetic intelligence.Cognition is an abstract property of advanced living organisms, therefore it is studied as a direct property of a brain or of an abstract mind on subsymbolic and symbolic levels.
In
psychology and in
artificial intelligence it is used to refer to the
mental functions,
mental processes and states of
intelligent entities (humans, human organizations, highly autonomous robots), with a particular focus toward the study of such mental processes as,
comprehension,
inferencing,
decision-making,
planning and
learning (see also
cognitive science and
cognitivism). Recently, advanced cognitive researchers are especially focused on the capacities of
abstraction, generalization,
concretization/specialization and meta-reasoning which descriptions involve such concepts as, beliefs,
knowledge, desires,
preferences and intentions of intelligent individuals/
objects/
agents/
systems. The term "cognition" is also used in a wider sense to mean the act of knowing or
knowledge, and may be interpreted in a social or cultural sense to describe the
emergent development of knowledge and concepts within a group that culminate in both
thought and action.
The sort of mental processes described as
cognitive or
cognitive processes are largely influenced by research which has successfully used this paradigm in the past. Consequently this description tends to apply to processes such as
memory,
attention,
perception,
action,
problem solving and
mental imagery. 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 behaviours.
While few people would deny that cognitive processes are the responsibility of the
brain, a cognitive theory will not necessarily make any reference to the brain or any other biological process (compare
neurocognitive). It may purely describe behaviour 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 which 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 conversly, evolutionary-based perspectives can inform hypotheses about cognitive functional systems
evolutionary psychology.
The theoretical school of thought derived from the 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).
Influence and influences
This success has led to it being applied in a wide range of areas:
*Psychology (particularly
cognitive psychology),
cognitive science and
psychophysics*
Cognitive neuroscience,
neurology and
neuropsychology*
Behavioral economics and
Behavioral finance *
Artificial intelligence and
cybernetics*
Ergonomics and
user interface design
*
Philosophy of mind*
Linguistics, especially
psycholinguistics and
cognitive linguistics*
Economics, especially
experimental economics*
Learning styles and
LearningIn its widest sense, the field is quite eclectic and draws from a number of areas, such as:
*
Computer science and
information theory, where attempts at
artificial intelligence,
collective intelligence and
robotics focus on mimicking living beings' capacities for cognition, or applying the experience gathered in one place by one being to actions by another being elsewhere.
*
Philosophy,
epistemology and
ontology *
Moral philosophy where it deals with the problem of
ignorance, often seen as the opposite of cognition.
*
Biology and
neuroscience*
Mathematics and
probability*
Physics, where
observer effects are studied in depth mathematically.
On an individual being level, these questions are studied by the separate fields above, but are also more integrated into
cognitive ontology of various kinds. This challenges the older
linguistically-dependent views of
ontology, wherein one could debate being, perceiving, and doing, with no cognizance of innate human limits, varying human lifeways, and loyalties that may let a being "know" something (see
qualia) that for others remains very much in
doubt.
On the level of an individual mind, an
emergent behavior might be the formation of a new concept, 'bubbling up' from below the conscious level of the mind. A simple way of stating this is that beings preserve their own attention and are at every level concerned with avoiding
interruption and distraction. Such
cognitive specialization can be observed in particular in language, with adults markedly less able to hear or say distinctions made in languages to which they were not exposed in youth.
By the
1980s, researchers in the Engineering departments of the
University of Leeds,
UK hypothesized that 'Cognition is a form of
compression', i.e., cognition was an
economic, not just a
philosophical or a
psychological process; in other words, skill in the process of cognition confers a
competitive advantage. An implication of this view is that choices about what to cognize are being made at all levels from the neurological expression up to species-wide priority setting; in other words, the compression process is a form of optimization. This is a force for
self-organizing behavior; thus we have the opportunity to see samples of
emergent behavior at each successive level, from individual, to groups of individuals, to formal organizations, to societies.
In multiple
observations, some dating back to antiquity,
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', which in fact requires a narrow, yet evolutionarily reliably occurring, set of inputs. 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 errornous in politics, economy and industry for the reason of different reciprocally dependent socio-cognitive factors. This domain becames the field of interest of emergent socio-cognitive engineering (
Google search).
One famous image,
Earthrise, taken during
Apollo 8, the first Apollo mission to the Moon, shows planet Earth in a single photograph.
Earthrise is now the icon for
Earth Day, which did not arise until after the image became widespread. At this level, an example of an 'emergent behavior' might be
concern for Spaceship Earth, as encouraged by the development of orbiting
space observatories etc.
Other concepts which seem to have arisen only recently (in the last century) include increased expectations for
human rights. In this case, an example of an 'emergent behavior' might perhaps be the use of the
mass media to publicize inequities in the
human condition, perhaps using highly portable cameras and telephones.
Example of emergent organization
It is possible to find other examples of critical mass necessary to develop a concept. For example a nascent
coalition of individuals might fail in the implementation of some
agreement among them; but in the words of
Ward Cunningham, the inventor of the
Wiki-wiki Web:
I thought there would be failure modes, but I wasn't surprised that communities found ways around them. I thought it was important that when the organization proved to be wrong, people could reorganize on their own, that organization could emerge.In other words, when the
organization adapted, the
concept adapted and survived the incipient failure mode.
Cognition is a diffuse term and is used in radically different ways by different disciplines. In psychology, it refers to an
information processing view of an individual's psychological
functions. Wider interpretations of the meaning of
cognition link it to the development of
concepts; individual minds, groups, organizations, and even larger coalitions of
entities can be modelled as
societies which
cooperate to form
concepts. The autonomous elements of each '
society' would have the opportunity to demonstrate
emergent behavior in the face of some crisis or opportunity. Cognition can also be interpreted as "understanding and trying to make sense of the world". In the above enlarged context different new generalized systemic perspectives and models are employed, see for example the
systemic TOGA meta-theory.
