Cognitive science is the interdisciplinary, scientific study of the mind and its processes. It examines the nature, the tasks, and the functions of cognition. Mental faculties of concern to cognitive scientists include language, perception, memory, attention, reasoning, and emotion; to understand these faculties, cognitive scientists borrow from fields such as linguistics, psychology, artificial intelligence, philosophy, neuroscience, and anthropology. The typical analysis of cognitive science spans many levels of organization, from learning and decision-making to logic and planning; from neural circuitry to modular brain organization. One of the fundamental concepts of cognitive science is that "thinking can best be understood in terms of representational structures in the mind and computational procedures that operate on those structures."
A concept is an abstract idea that serves as a foundation for more concrete principles, thoughts, and beliefs. Concepts play an important role in all aspects of cognition. As such, concepts are studied within such disciplines as linguistics, psychology, and philosophy, and these disciplines are interested in the logical and psychological structure of concepts, and how they are put together to form thoughts and sentences. The study of concepts has served as an important flagship of an emerging interdisciplinary approach, cognitive science.
In their most common sense, the terms thought and thinking refer to cognitive processes that can happen independently of sensory stimulation. Their most paradigmatic forms are judging, reasoning, concept formation, problem solving, and deliberation. But other mental processes, like considering an idea, memory, or imagination, are also often included. These processes can happen internally independent of the sensory organs, unlike perception. But when understood in the widest sense, any mental event may be understood as a form of thinking, including perception and unconscious mental processes. In a slightly different sense, the term thought refers not to the mental processes themselves but to mental states or systems of ideas brought about by these processes.
Steven Arthur Pinker is a Canadian-American cognitive psychologist, psycholinguist, popular science author, and public intellectual. He is an advocate of evolutionary psychology and the computational theory of mind.
Cognitive development is a field of study in neuroscience and psychology focusing on a child's development in terms of information processing, conceptual resources, perceptual skill, language learning, and other aspects of the developed adult brain and cognitive psychology. Qualitative differences between how a child processes their waking experience and how an adult processes their waking experience are acknowledged. Cognitive development is defined as the emergence of the ability to consciously cognize, understand, and articulate their understanding in adult terms. Cognitive development is how a person perceives, thinks, and gains understanding of their world through the relations of genetic and learning factors. There are four stages to cognitive information development. They are, reasoning, intelligence, language, and memory. These stages start when the baby is about 18 months old, they play with toys, listen to their parents speak, they watch TV, anything that catches their attention helps build their cognitive development.
In the philosophy of mind, innatism is the view that the mind is born with already-formed ideas, knowledge, and beliefs. The opposing doctrine, that the mind is a tabula rasa at birth and all knowledge is gained from experience and the senses, is called empiricism.
Stephen P. Stich is an American academic who is Distinguished Professor of Philosophy and Cognitive Science at Rutgers University, as well as an Honorary Professor in Philosophy at the University of Sheffield. Stich's main philosophical interests are in the philosophy of mind, epistemology, and moral psychology. His 1983 book, From Folk Psychology to Cognitive Science: The Case Against Belief, received much attention as he argued for a form of eliminative materialism about the mind. He changed his mind, in later years, as indicated in his 1996 book Deconstructing the Mind.
In the field of psychology, nativism is the view that certain skills or abilities are "native" or hard-wired into the brain at birth. This is in contrast to the "blank slate" or tabula rasa view, which states that the brain has inborn capabilities for learning from the environment but does not contain content such as innate beliefs. This factor contributes to the ongoing nature versus nurture dispute, one borne from the current difficulty of reverse engineering the subconscious operations of the brain, especially the human brain.
Hilary Kornblith is an American philosopher. He is a professor of philosophy at the University of Massachusetts Amherst and one of contemporary epistemology's most prominent proponents of naturalized epistemology.
James Henry Fetzer is an American professor emeritus of the philosophy of science at the University of Minnesota Duluth, known for promoting conspiracy theories and Holocaust denial. Fetzer has worked on assessing and clarifying the forms and foundations of scientific explanation, probability in science, philosophy of mind, and philosophy of cognitive science, especially artificial intelligence and computer science.
Jeffrey Locke Elman was an American psycholinguist and professor of cognitive science at the University of California, San Diego (UCSD). He specialized in the field of neural networks.
Gary Fred Marcus is an American psychologist, cognitive scientist, and author, known for his research on the intersection of cognitive psychology, neuroscience, and artificial intelligence (AI).
Peter Carruthers is a philosopher working primarily in the area of philosophy of mind. He is Professor of Philosophy at the University of Maryland, associate member of Neuroscience and Cognitive Science Program and member of the Committee for Philosophy and the Sciences.
In linguistics, the innateness hypothesis, also known as the nativist hypothesis, holds that humans are born with at least some knowledge of linguistic structure. On this hypothesis, language acquisition involves filling in the details of an innate blueprint rather than being an entirely inductive process. The hypothesis is one of the cornerstones of generative grammar and related approaches in linguistics. Arguments in favour include the poverty of the stimulus, the universality of language acquisition, as well as experimental studies on learning and learnability. However, these arguments have been criticized, and the hypothesis is widely rejected in other traditions such as usage-based linguistics. The term was coined by Hilary Putnam in reference to the views of Noam Chomsky.
Kim Sterelny is an Australian philosopher and professor of philosophy in the Research School of Social Sciences at Australian National University and Victoria University of Wellington. He is the winner of several international prizes in the philosophy of science, and was previously editor of Biology and Philosophy. He is also a member of the Australian Academy of the Humanities. He is currently the First Vice President of the Division for Logic, Methodology and Philosophy of Science and Technology of the International Union of History and Philosophy of Science and Technology (2020–2023).
Stephen Crain is the director of the ARC Centre of Excellence in Cognition and its Disorders (CCD), and a distinguished professor at Macquarie University in the Department of Linguistics. He is a well-known researcher specializing in language acquisition, focusing specifically on syntax and semantics. Crain views language acquisition as based on language-specific faculties, and he conducts his research in the tradition of Chomskyan generative grammar. Recently, Crain has proposed that language is based on a universal logical system, and he has begun to explore the neural correlates of language acquisition from a cross-linguistic perspective using magnetoencephalography (MEG). Crain received a BA in philosophy from the University of California, Los Angeles in 1971 and a PhD in cognitive science with an emphasis in linguistics from the University of California, Irvine in 1980. Crain was employed as a professor of linguistics at the University of Connecticut from 1986 to 1995. During that time he was also a senior scientist at Haskins Laboratories in New Haven, Connecticut. After leaving UConn, he took a position as professor of linguistics at the University of Maryland, College Park, from 1995 to 2003, before accepting a position as a professor of cognitive science at Macquarie in 2004, where he has remained since. He was deputy director of the Macquarie Centre for Cognitive Science from 2004 until 2010, and director of the Centre for Language Sciences from 2007 until 2010. He led the successful bid for an ARC Centre of Excellence in Cognition and its Disorders, which is funded from 2011 until 2017.
The East Pole–West Pole divide in the fields of cognitive psychology and cognitive neuroscience is an intellectual schism between researchers subscribing to the nativist and empiricist schools of thought. The term arose from the fact that much of the theory and research supporting nativism, modularity of mind, and computational theory of mind originated at several universities located on the East Coast, including Harvard University, the University of Michigan, Massachusetts Institute of Technology, and Tufts University. Conversely, much of the research and theory supporting empiricism, emergentism, and embodied cognition originated at several universities located on the West Coast, including the University of California, Berkeley, the Salk Institute, and, most notably, the University of California, San Diego. In reality, the divide is not so clear, with many universities and scholars on both coasts supporting each position, as well as more moderate positions in between the two extremes. The phrase was coined by Jerry Fodor at an MIT conference on cognition, at which he referred to another researcher as a "West Coast theorist," apparently unaware that the researcher worked at Yale University.
John L. Pollock (1940–2009) was an American philosopher known for influential work in epistemology, philosophical logic, cognitive science, and artificial intelligence.
Gualtiero Piccinini is an Italian–American philosopher known for his work on the nature of mind and computation as well as on how to integrate psychology and neuroscience. He is Curators' Distinguished Professor in the Philosophy Department at the University of Missouri, Columbia.
Keith Frankish is a British philosopher specializing in philosophy of mind, philosophy of psychology, and philosophy of cognitive science. He is an Honorary Reader at the University of Sheffield, UK, Visiting Research Fellow with The Open University, and adjunct Professor with the Brain and Mind Programme at the University of Crete. He is known for his "illusionist" stance in the theory of consciousness. He holds that the conscious mind is a virtual system, a trick of the biological mind. In other words, phenomenality is an introspective illusion. This position is in opposition to dualist theories, reductive realist theories, and panpsychism.
