'''Cognitive science''' is the interdisciplinary study of the [[cognitive processes]] underlying the acquisition and use of [[knowledge]]. It draws from converging evidence and methodology of diverse fields, including [[psychology]], [[neuroscience]], [[philosophy]], [[computer science]], [[anthropology]] and [[linguistics]]. The term ''cognitive science'' was coined by [[H. Christopher Longuet-Higgins|Christopher Longuet-Higgins]] in his 1973 commentary on the [[Lighthill report]], which concerned the then-current state of [[Artificial Intelligence]] research. In the same decade, the journal ''Cognitive Science'' and the Cognitive Science Society began.

== History ==
In [[Ancient Greece]], philosophers [[Plato]] and [[Aristotle]] sought to understand the nature of human knowledge. In the 17th century, [[Descartes]] popularized the notion that the body and the mind were two separate entities, known as [[Res Extensa]] and [[Res Cogitans]]. Other thinkers on the matter of the mind in the 17th and 18th centuries included [[George Berkeley]], [[Robert Burton]], [[Thomas Hobbes]], [[David Hume]], [[Immanuel Kant]], and [[John Locke]]. In the 1870s, [[Wilhelm Wundt]] moved the study of human knowledge into the realm of [[experimental psychology]]. In the early 20th century, the popular notion of mind was altered by [[John B. Watson]]'s behaviorist viewpoint that consciousness was not an appropriate question for scientific inquiry and that only observable behavior should be studied. In the 1950s this prevailing viewpoint began to change again as scientists started conceptualizing theories of mind based on complex representations and computational procedures. [[George Miller]] pioneered the concept of mental representations, chunks of information that are encoded and decoded within the mind. [[John McCarthy (computer scientist)|John McCarthy]], [[Marvin Minsky]], [[Allen Newell]], and [[Herbert Simon]] founded the field of [[artificial intelligence]] around the same time. [[Noam Chomsky]] further removed the study of the mind from the behaviorism of Watson, [[B.F. Skinner]], and others that had been psychology's primary focus.

==Principles of cognitive science==
===Approaches===
There are several approaches to the study of cognitive science. These approaches may be classified broadly as symbolic, connectionist, and dynamic systems.

* Symbolic - holds that cognition can be explained using operations on [[symbol]]s, by means of explicit computational theories and models of [[mind|mental]] (but not brain) processes analogous to the workings of a digital computer.
* [[Connectionism|Connectionist]] (subsymbolic) - holds that cognition can only be modeled and explained by using artificial [[neural networks]] on the level of physical brain properties.
* Dynamic Systems - holds that cognition can be explained by means of a continuous [[dynamical system]] in which all the elements are interrelated, like the [[Centrifugal governor|Watt Governor]].

===Levels of analysis===
One of the central principles of [[systemics]] applied in the symbolic approach to cognitive science is that (1) there are different Levels of Analysis (LOA) from which the brain and mind can be studied, and (2) mental phenomena are best studied from ''multiple'' levels of abstraction. For example, these levels are broken into three (not well separated) groups, based on [[David Marr (psychologist)|Marr's]] description of them:

* Computational (Behavioral) level: describes the directly observable output (or behavior) of a system.
* Algorithmic (Functional) level: describes how information is processed to produce the behavioral output.
* Implementational (Physical) level: describes the physical substrate that the system consists of (e.g. the brain; neurons).

A simple analogy often used to describe LOA is to compare the brain to a [[computer]]. The physical level would consist of the computer's [[hardware]], the behavioral level represents the computer's [[software]], and the functional level would be the computer's [[operating system]], which allows the software and hardware components to communicate.

A central tenet of cognitive science is that a complete understanding of the mind/brain cannot be attained by studying only a single level. For example, consider the problem of remembering a phone number and recalling it later. How does this process occur? One approach would be to study behavior through direct observation. A person could be presented with a phone number, asked to recall it after some delay. Then the accuracy of the response could be measured. Another approach would be to study the firings of individual neurons while a person is trying to remember the phone number. Neither of these experiments on their own would fully explain ''how'' the process of remembering a phone number works. Even if the technology to map out every neuron in the brain in real-time were available, and it were known when each neuron was firing, it would still be impossible to know how a particular firing of neurons translates into the observed behavior. Thus an understanding of how these two levels relate to each other is needed. This can be provided by a functional level account of the process. Studying a particular phenomenon from multiple levels creates a better understanding of the processes that occur in the brain to give rise to a particular behavior. For criticisms of this framework see [[Functionalism (psychology)]].

===Interdisciplinary nature===
Cognitive science is an interdisciplinary field with contributors from various fields, including [[psychology]], [[neuroscience]], [[linguistics]], [[philosophy]], [[computer science]], [[anthropology]], [[biology]], and [[physics]]. Cognitive science tends to view the world outside the mind much as other sciences do. Thus it too has an objective, observer-independent existence. The field is usually seen as compatible with the physical sciences, and uses the [[scientific method]] as well as [[simulation]] or [[model (abstract)|modeling]], often comparing the output of models with aspects of human behavior. Still, there is much disagreement about the exact relationship between cognitive science and other fields, and the interdisciplinary nature of cognitive science is largely both unrealized and circumscribed.

Many, but not all, who consider themselves cognitive scientists have a [[functionalism (philosophy of mind)|functionalist]] view of the mind—the view that mental states are classified functionally, such that any system that performs the proper function for some mental state is considered to be in that mental state. Thus, according to functionalism about the mind, even non-human systems, such as other animal species, alien life forms, or advanced computers can, in principle, have mental states. This perspective is one of the reasons the term "cognitive science" is not exactly coextensive with [[neuroscience]], [[psychology]], or some combination of the two.

From the external point of view, the largest interdisciplinary context of cognitive science is [[systemics]]. It includes the [[socio-cognitive]] extension of the cognition models and theories over different social environments social systems, with the emphasis on [[distributed cognition]] and [[intelligence]].

===''Cognitive'' science: the term===
The term "cognitive" in "cognitive science" is "used for any kind of mental operation or structure that can be studied in precise terms" ([[George Lakoff|Lakoff]] and [[Mark Johnson (professor)|Johnson]], [[1999]]). This conceptualization is very broad, and should not be confused with how "cognitive" is used in some traditions of analytic philosophy, where "cognitive" has to do only with formal rules and truth conditional semantics. (Nonetheless, that interpretation would bring one close to the historically dominant school of thought within cognitive science on the nature of cognition - that it is essentially symbolic, propositional, and logical.)

The earliest entries for the word "''cognitive''" in the [[Oxford English Dictionary|OED]] take it to mean roughly ''pertaining "to the action or process of knowing"''. The first entry, from [[1586]], shows the word was at one time used in the context of discussions of [[Plato]]nic theories of [[knowledge]]. Most in cognitive science, however, presumably do not believe their field is the study of anything as certain as the knowledge sought by Plato.

==Scope of cognitive science==
'''Cognitive science''' is a large field, and covers a wide array of topics on cognition. However, it should be recognized that cognitive science is not equally concerned with every topic that might bear on the nature and operation of the mind or intelligence. Social and cultural factors, emotion, consciousness, [[animal cognition]], [[comparative psychology|comparative]] and [[evolutionary psychology|evolutionary]] approaches are frequently de-emphasized or excluded outright, often based on key philosophical conflicts. Some within the cognitive science community, however, consider these to be vital topics, and advocate the importance of investigating them.

In any way, the essential questions of cognitive science seem to be: ''What is intelligence?'' and ''How is it possible to model it computationally?''.

Below are some of the main topics that '''cognitive science''' is concerned with. This is not an exhaustive list, but is meant to cover the wide range of intelligent behaviors. See [[List of cognitive science topics]] for a list of various aspects of the field.

===Artificial intelligence===
{{Main|Artificial intelligence}}

''"... One major contribution of AI and cognitive science to psychology has been the information processing model of human thinking in which the metaphor of brain-as-computer is taken quite literally.
."'' [http://www.aaai.org/AITopics/html/cogsci.html#simon AAAI Web pages].

Artificial intelligence (AI) involves the study of cognitive phenomena in machines. One of the practical goals of AI is to implement aspects of human intelligence in computers. Computers are also widely used as a tool with which to study cognitive phenomena. [[computer model|Computational modeling]] uses simulations to study how human intelligence may be structured. (See the section on computational modeling in the Research Methods section.)

There is some debate in the field as to whether the mind is best viewed as a huge array of small but individually feeble elements (i.e. neurons), or as a collection of higher-level structures such as symbols, schemas, plans, and rules. The former view uses [[connectionism]] to study the mind, whereas the latter emphasizes symbolic computations. One way to view the issue is whether it is possible to accurately simulate a human brain on a computer without accurately simulating the neurons that make up the human brain.

===Attention===
{{Main|Attention}}

Attention is the selection of important information. The human mind is bombarded with millions of stimuli and it must have a way of deciding which of this information to process. Attention is sometimes seen as a spotlight, meaning one can only shine the light on a particular set of information. Experiments that support this metaphor include the [[dichotic listening]] task (Cherry, 1957) and studies of inattentional blindness (Mack and Rock, 1998). In the dichotic listening task, subjects are bombarded with two different messages, one in each ear, and told to focus on only one of the messages. At the end of the experiment, when asked about the content of the unattended message, subjects cannot report it.

===Language processing===
[[Image:Cgisf-tgg.png|thumb|230px||An example of a phrase structure tree. This is one way of representing human language that shows how different components are organized hierarchically.]]
{{Main|Cognitive linguistics|Language|Linguistics|Psycholinguistics}}

The ability to learn and understand language is an extremely complex process. Language is acquired within the first few years of life, and all humans under normal circumstances are able to acquire language proficiently. Some of the driving research questions in studying how the brain processes language include: (1) To what extent is linguistic knowledge innate or learned?, (2) Why is it more difficult for adults to acquire a second-language than it is for infants to acquire their first-language?, and (3) How are humans able to understand novel sentences they have never heard before?

The study of language processing ranges from the investigation of the sound patterns of speech to the meaning of words and whole sentences. [[Linguistics]] often divides language processing into [[orthography]], [[phonology]] and [[phonetics]], [[syntax|syntactics]], [[semantics]], and [[pragmatics]]. Many aspects of language can be studied from each of these components and from their interaction.

The study of language processing in '''cognitive science''' is closely tied to the field of linguistics. Linguistics was traditionally studied as a part of the humanities, including studies of history, art and literature. In the last fifty years or so, more and more researchers have studied knowledge and use of language as a cognitive phenomenon, the main problems being how knowledge of language can be acquired and used, and what precisely it consists of. [[Linguist]]s have found that, while humans form sentences in ways apparently governed by very complex systems, they are remarkably unaware of the rules that govern their own speech. Thus linguists must resort to indirect methods to determine what those rules might be. If speech is indeed governed by rules, they appear to be opaque to any conscious consideration.

A very [[Fecundity|fecund]] way to approach cognitive issues in language is the [[pragmatics]] of language, that is, the current use of the language by a real speaker. From a pragmatic analytical perspective it is possible to show that some people who have a profession in which they categorically work with language (e.g. journalists) have a behavior which is not predictable by known theories. The pragmatic approach is also useful in the study of [[Collective decision-making#Decision making in groups|collective distributed decision making]], particularly in broadcasted systems (for instance aviation approach control - APP).

===Learning and development===
{{Main|Learning|Developmental psychology}}

Learning and development are the processes by which we acquire knowledge and information over time. Infants are born with little or no knowledge (depending on how knowledge is defined), yet they rapidly acquire the ability to use language, walk, and recognize people and objects. Research in learning and development aims to explain the mechanisms by which these processes might take place.

A major question in the study of cognitive development is the extent to which certain abilities are [[innate]] or learned. This is often framed in terms of the nature versus nurture debate. The [[Psychological nativism|nativist]] view emphasizes that certain features are innate to an organism and are determined by its [[genetics|genetic]] endowment. The [[Empiricism|empiricist]] view, on the other hand, emphasizes that certain abilities are learned from the environment. It is clear that intelligent behavior has components that are both innate and learned, but the extent to which particular behaviors are innate is a major research question. In the area of [[language acquisition]], for example, many questions remain about whether or not a special language acquisition device is necessary to facilitate the learning of language, or if humans can learn language through more general learning processes that take advantage of the information available in the environment.

A significant step was made in cognitive science in 1968 when [[Anthony V. Manzo]] was able to demonstrate that reading comprehension could be dramatically improved through mental modeling, also known as [[cognitive apprenticeship]] training. Previously reading comprehension was believed to be a best predictor of Intelligence, and therefore nearly immutable. The research methodology was based on a teaching practice known as the [[ReQuest Procedure]].

===Memory===
{{Main|Memory}}

Memory allows us to store information for later retrieval. Memory is often thought of consisting of both a long-term and short-term store. Long-term memory allows us to store information over prolonged periods (days, weeks, years). We do not yet know the practical limit of long-term memory capacity. Short-term memory allows us to store information over short time scales (seconds or minutes).

Memory is also often grouped into declarative and procedural forms. [[Declarative memory]]--grouped into subsets of [[Semantic memory|semantic]] and [[Episodic memory|episodic forms of memory]]--refers to our memory for facts and specific knowledge, specific meanings, and specific experiences (e.g., Who was the first president of the U.S.A.?, or "What did I eat for breakfast four days ago?). [[Procedural memory]] allows us to remember actions and motor sequences (e.g. how to ride a bicycle) and is often dubbed implicit knowledge or memory .

Cognitive scientists study memory just as psychologists do, but tend to focus in more on how memory bears on [[cognitive process]]es, and the interrelationship between cognition and memory. One example of this could be, what mental processes does a person go through to retrieve a long-lost memory? Or, what differentiates between the cognitive process of recognition (seeing hints of something before remembering it, or memory in context) and recall (retrieving a memory, as in "fill-in-the-blank")?

===Perception and action===
[[Image:Necker cube.svg|thumb|150px|The Necker cube, an example of a visual illusion.]]

{{Main|Perception}}

Perception is the ability to take in information via the [[senses]], and process it in some way. [[Visual perception|Vision]] and [[Hearing (sense)|hearing]] are two dominant senses that allow us to perceive the environment. Some questions in the study of visual perception, for example, include: (1) How are we able to recognize objects?, (2) Why do we perceive a continuous visual environment, even though we only see small bits of it at any one time? One tool for studying visual perception is by looking at how people process [[visual illusions]]. The image on the right of a Necker cube is an example of a bistable percept, that is, the cube can be interpreted as being oriented in two different directions.

The study of [[haptic]] ([[tactile]]), [[olfactory]], and [[gustatory]] stimuli also fall into the domain of perception.

Action is taken to refer to the output of a system. In humans, this is accomplished through motor responses. Spatial planning and movement, speech production, and complex motor movements are all aspects of action.

==Research methods==
Many different methodologies are used to study '''cognitive science'''. As the field is highly interdisciplinary, research often cuts across multiple areas of study, drawing on research methods from [[psychology]], [[neuroscience]], [[computer science]] and [[systems theory]].

===Behavioral experiments===
In order to have a description of what constitutes intelligent behavior, one must study behavior itself. This type of research is closely tied to that in [[cognitive psychology]] and [[psychophysics]]. By measuring behavioral responses to different stimuli, one can understand something about how those stimuli are processed.

* ''Reaction time.'' The time between the presentation of a stimulus and an appropriate response can indicate differences between two cognitive processes, and can indicate some things about their nature. For example, if in a search task the reaction times vary proportionally with the number of elements, then it is evident that this cognitive process of searching involves serial instead of parallel processing.

* ''Psychophysical responses.'' Psychophysical experiments are an old psychological technique, which has been adopted by cognitive psychology. They typically involve making judgments of some physical property, e.g. the loudness of a sound. Correlation of subjective scales between individuals can show cognitive or sensory biases as compared to actual physical measurements. Some examples include:
** sameness judgments for colors, tones, textures, etc.
** threshold differences for colors, tones, textures, etc.

* ''[[Eye tracking]].'' This methodology is used to study a variety of cognitive processes, most notably visual perception and language processing. The fixation point of the eyes is linked to an individual's focus of attention. Thus, by monitoring eye movements, we can study what information is being processed at a given time. Eye tracking allows us to study cognitive processes on extremely short time scales. Eye movements reflect online decision making during a task, and they provide us with some insight into the ways in which those decisions may be processed.

===Brain imaging===
{{main|Neuroimaging}}

[[Image:Hypothalamus.jpg|thumb|150px||Image of the human head with the brain. The arrow indicates the position of the [[hypothalamus]].]]

Brain imaging involves analyzing activity within the brain while performing various cognitive tasks. This allows us to link behavior and brain function to help understand how information is processed. Different types of imaging techniques vary in their temporal (time-based) and spatial (location-based) resolution. Brain imaging is often used in [[cognitive neuroscience]].

* ''[[Single photon emission computed tomography]]'' and ''[[Positron emission tomography]]''. SPECT and PET use radioactive isotopes, which are injected into the subject's bloodstream and taken up by the brain. By observing which areas of the brain take up the radioactive isotope, we can see which areas of the brain are more active than other areas. PET has similar spatial resolution to fMRI, but it has extremely poor temporal resolution.

* ''[[Electroencephalography]]''. EEG measures the electrical fields generated by large populations of neurons in the cortex by placing a series of electrodes on the scalp of the subject. This technique has an extremely high temporal resolution, but a relatively poor spatial resolution.

* ''[[Functional magnetic resonance imaging]]''. fMRI measures the relative amount of oxygenated blood flowing to different parts of the brain. More oxygenated blood in a particular region is assumed to correlate with an increase in neural activity in that part of the brain. This allows us to localize particular functions within different brain regions. fMRI has moderate spatial and temporal resolution.

* ''[[Optical imaging]]''. This technique uses infrared transmitters and receivers to measure the amount of light reflectance by blood near different areas of the brain. Since oxygenated and deoxygenated blood reflects light by different amounts, we can study which areas are more active (i.e., those that have more oxygenated blood). Optical imaging has moderate temporal resolution, but poor spatial resolution. It also has the advantage that it is extremely safe and can be used to study infants' brains.

*''[[Magnetoencephalography]].'' MEG measures magnetic fields resulting from cortical activity. It is similar to [[Electroencephalography|EEG]], except that it has improved spatial resolution since the magnetic fields it measures are not as blurred or attenuated by the scalp, meninges and so forth as the electrical activity measured in EEG is. MEG uses SQUID sensors to detect tiny magnetic fields.

===Computational modeling===
[[Image:MultiLayerNeuralNetwork english.png|thumb|200px|A Neural network with two layers.]]

[[computer model|Computational models]] require a mathematically and logically formal representation of a problem. Computer models are used in the simulation and experimental verification of different specific and general [[property|properties]] of [[intelligence]]. Computational modelling can help us to [[understand]] the functional organization of a particular cognitive phenomenon.

* ''Symbolic modeling'', is based on the technologies of [[expert system]]s or more general [[Knowledge-Based System]]s. They are especially used in [[information engineering]] and, recently, in generalized [[systemics]], see for example [[GOFAI]].
* ''Subsymbolic modeling'' which includes ''[[Connectionism|Connectionist/neural network models]].'' Connectionism relies on the idea that the mind/brain is composed of simple nodes and that the power of the system comes primarily from the existence and manner of connections between the simple nodes. [[Neural nets]] are textbook implementations of this approach. Some critics of this approach feel that while these models approach biological reality as a repetition of how the system works, they lack explanative powers as complicated systems of connections with even simple rules are extremely complex and often less interpretable than the system they model.
* '' Physical [[Dynamical systems]].''

All the above approaches tend to be generalized to the form of integrated computational models of a synthetic/abstract intelligence, in order to be applied to the explanation and improvement of individual and social/organizational [[decision-making]].

===Neurobiological methods===
Research methods borrowed directly from [[neuroscience]] and [[neuropsychology]] can also help us to understand aspects of intelligence. These methods allow us to understand how intelligent behavior is implemented in a physical system.

* [[Single-cell recording]]
* [[Transcranial direct current stimulation|Direct brain stimulation]]
* [[Animal models]]
* [[Postmortem Studies]]

==Key findings==
'''Cognitive science''' has much to its credit. Among other accomplishments, it has given rise to models of human [[cognitive bias]] and [[risk]] perception, and has been influential in the development of [[behavioral finance]], part of [[economics]]. It has also given rise to a new theory of the [[philosophy of mathematics]], and many theories of [[artificial intelligence]], [[persuasion]] and [[coercion]]. It has made its presence firmly known in the [[philosophy of language]] and [[epistemology]] - a modern revival of rationalism - as well as constituting a substantial wing of modern [[linguistics]].

== Criticisms ==
The philosophical underpinnings of research in cognitive science have been continually criticized by philosophers and scientists alike. See [[Functionalism (Cognitive Science)]] for an extended entry on this.

==Notable researchers in cognitive science==
{{Seealso|List of cognitive scientists}}

Some of the more recognized names in cognitive science are usually either the most controversial or the most cited. Within philosophy familiar names include [[Daniel Dennett]] who writes from a computational systems perspective, [[John Searle]] known for his controversial [[Chinese Room]], Jerry Fodor who advocates [[Functionalism (psychology)|functionalism]], and [[Douglas Hofstadter]]. [[Douglas Hofstadter|Hofstadter]], famous for writing [[Gödel, Escher, Bach]], which questions the nature of words and thought, is Director of the [[Fluid Analogies Research Group]] of the [[Center for Research on Concepts and Cognition]] at [[Indiana University (Bloomington)|Indiana University]]. In the realm of linguistics [[Noam Chomsky]] and [[George Lakoff]] have been influential. Popular names in the discipline of psychology include [[James McClelland]] and [[Steven Pinker]].
