Cognitive science

Cognitive science is the interdisciplinary study of mind and intelligence. It embraces philosophy, psychology, artificial intelligence, neuroscience, linguistics and anthropology.Thagard, P. Introduction to Cognitive Science 2005, page 1 Cognitive science is a relatively young and developing science. Nevetheless, it has already had a fair share of influence on several fields, particularly in the humanities. There is even cognitive archaeology.
==Origins==
Cognitive science grew out of the "cognitive revolution" of the 1950s and 1960s that gave birth to the field of cognitive psychology. Cognitive psychology fused the theoretical approach of Gestalt psychology and early models of artificial intelligence with the experimental approach of behaviorism. Early cognitive psychology tended to ignore the physical brain itself, seeing it as a "black box", though this has changed with the proliferation of brain scanning technologies and the rise of cognitive neuroscience. "Cognitive science" as a term was coined shortly after "cognitive psychology" to refer to developments in machine learning and artificial intelligence, though it soon became an umbrella term for various cognitive approaches to fields as listed above, sometimes being referred to in the plural "the cognitive sciences" due to this.
==Influential figures in cognitive science==
* — Incorporated studies of emotion and neurobiology into cognitive approaches.
* and — Launched the study of cognitive biases.
*Douglas Hofstadter — Philosophy of mind and artificial intelligence, especially the concept of emergence.
* — Metaphor and linguistics. Known for developing an approach to philosophy of mind called "
* — Machine learning, artificial intelligence, computer vision. Coined the term "cognitive science." Also a theoretical chemist.
* — Applied concepts from computer science and behavioral research to a wide variety of fields, including psychology and economics. Coined the terms "bounded rationality" and "satisficing."
* — Known for his work on modularity of mind and the language of thought.Although in more recent times, he's known for this stinker.
*Noam Chomsky — Known for challenging B.F. Skinner and behaviorist theories of mind.
* — Memory and intelligence. Coined the term "cognitive psychology."
* — Neuroscience of perception, synesthesia, and phantom limbs.
* — Visual perception and levels of analysis.
==Pseudoscience and skepticism==
Since cognitive science focuses heavily on memory, sensory perception, learning, and rationality, research from the field has been adopted by proponents of scientific skepticism. Cognitive biases in particular have become a staple of skeptical writing. Some cognitive scientists and psychologists, such as Elizabeth Loftus, have worked directly with skeptical organizations. Cognitive scientists likewise have used studies of pseudoscience, folk conceptions of science, religion, and mysticism to draw conclusions about the working of the human mind. One new development is the , which de-emphasizes belief (because it cannot be objectively measured), and is able to explain paradoxes such as why an agnostic with musical training might join a church choir (but not tithe).
==Two thousand years of Western thought overturned==
A major philosophical approach to the mind and reality called embodied cognition, promoted by figures such as Lakoff and Margaret Wilson, has grown out of cognitive science. While acknowledging the usefulness of Western metaphysical thought since about the time of Socrates or so, Lakoff and his colleague Mark Johnson have this to say:
Cognitive scientists' broad definition of "cognition" asserts that 95% or more of it operates unconsciously: too rapidly and too far below the threshold of awareness for us to notice."Conscious thought is the tip of an enormous iceberg. It is the rule of thumb among cognitive scientists that unconscious thought is 95 percent of all thought—and that may be a serious underestimate. Moreover, the 95 percent below the surface of conscious awareness shapes and structures all conscious thought. If the cognitive unconscious were not there doing this shaping, there could be not conscious thought." Lakoff and Johnson, 1999, p. 12 If it were not so, we would hardly be able to move through the world, manipulate objects in it, or speak about anything at all."Primary metaphors are part of the cognitive unconscious. We acquire them automatically and unconsciously via the normal process of neural learning and may be unaware that we have them. We have no choice in this process.
… not all primary metaphors are manifested in the words of a language. Some are manifested in grammar, others in gesture, art, or ritual. These nonlinguistic metaphors may, however, be secondarily expressed through language and other symbolic means. 
Contrary to long-standing opinion about metaphor, primary metaphor is not the result of a conscious multistage process of interpretation. Rather it is a matter of immediate conceptual mapping via neural connections. 
If you are a normal human being, you inevitably acquire an enormous range of primary metaphors just by going about the world constantly moving and perceiving. Whenever a domain of subjective experience or judgment is coactivated regularly with a sensorimotor domain, permanent neural connections are established via synaptic weight changes." Lakoff and Johnson, 1999, pp. 56-57 Empirical investigation of this unconscious cognition is, however, possible."The experimental techniques (for a survey, see Gibbs, R. 1994, The Poetics of Mind: Figurative Thought, Language, and Understanding. Cambridge University Press. pp. 161-167, 252-257) include the following seven types: priming, problem solving, inferential reasoning, image analysis, classification, verbal protocol analysis, and discourse comprehension." Lakoff and Johnson, 1999, p. 83
