Earl Keith Miller (born November 30, 1962, Columbus OH) is a systems/cognitive neuroscientist, whose research focuses on neural mechanisms of learning, memory, and cognition.
 Earl Miller is the Picower Professor of Neuroscience with the Picower Institute for Learning and Memory and the Department of Brain and Cognitive Sciences at Massachusetts Institute of Technology.
 He is also the Chief Scientific Officer and Co-founder of SplitSage
David Klahr (born 1939) is an American psychologist whose research ranges across the fields of cognitive development, psychology of science, and educational psychology and has been a professor at Carnegie Mellon University since 1969.
 He is the Walter van Dyke Bingham Professor of Cognitive Development and Education Sciences at Carnegie Mellon University and a member of the National Academy of Education, a Fellow of the American Psychological Association, a Charter Fellow of the Association for Psychological Science, on the Governing Board of the Cognitive Development Society, a Member of the Society for Research in Child Development, and the Cognitive Science Society.
 He was an Associate Editor of Developmental Psychology and has served on the editorial boards of several cognitive science journals, as well as on the National Science Foundation's subcommittee on Memory and Cognitive Processes, and the National Institutes of Health's Human Development and Aging Study Section.
The parallel terraced scan is a multi-agent based search technique that is basic to cognitive architectures, such as Copycat, Letter-string, the Examiner, Tabletop, and others.
 It was developed by John Rehling and Douglas Hofstadter at the Center for Research on Concepts and Cognition at Indiana University, Bloomington.
Douglas Richard Hofstadter (born February 15, 1945) is an American professor of cognitive science whose research focuses on the sense of "I" (sense of self in relation to the external world), consciousness, analogy-making, artistic creation, literary translation, and discovery in mathematics and physics.
 Hofstadter's book "Gödel, Escher, Bach: An Eternal Golden Braid", first published in 1979, won both the Pulitzer Prize for general non-fiction
Herbert Alexander Simon (June 15, 1916 – February 9, 2001) was an American political scientist, economist, sociologist, psychologist, and computer scientist whose research ranged across the fields of cognitive psychology, cognitive science, computer science, public administration, economics, management, philosophy of science, sociology, and political science, unified by studies of decision-making.
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.
Jim Davies is an American/Canadian cognitive scientist, playwright, artist, and author.
 He received his bachelor's degree in philosophy from the State University of New York at Oswego, his masters in psychology and his Ph.D. in computer science from the Georgia Institute of Technology.
 He is a full professor of Cognitive Science at the Institute of Cognitive Science and the School of Computer Science at Carleton University in Ottawa, Ontario where he is the director of the Science of Imagination Laboratory.
 His research focuses on visual reasoning, analogy, and imagination.
Aaron Sloman is a philosopher and researcher on artificial intelligence and cognitive science who was born in Rhodesia (now Zimbabwe).
 He is the author of several papers on philosophy, epistemology and artificial intelligence.
 He held the Chair in Artificial Intelligence and Cognitive Science at the School of Computer Science at the University of Birmingham, and before that a chair with the same title at the University of Sussex.
 He has collaborated with biologist Jackie Chappell on the evolution of intelligence.
 Since retiring he is Honorary Professor of Artificial Intelligence and Cognitive Science at Birmingham.
The Indiana Archives of Cognitive Science (IACS) is an online information portal providing information about the field of cognitive science.
 The purpose of IACS is to promote the study of cognitive science at the undergraduate level.
 The site provides information about history, current research trends, and career opportunities associated in cognitive science.
Copycat is a model of analogy making and human cognition based on the concept of the parallel terraced scan, developed in 1988 by Douglas Hofstadter, Melanie Mitchell, and others at the Center for Research on Concepts and Cognition, Indiana University Bloomington.
 The original Copycat was written in Common Lisp and is bitrotten (as it relies on now-outdated graphics libraries); however, Java and Python ports exist.
