4E Cognition

Albert Newen, Shaun Gallagher

4E cognition refers to the idea that cognition is embodied, embedded, enacted, and extended. Each of these four theses has been advanced in opposition to the idea that cognition is primarily a matter of what goes on in the head, and each draws attention to the fact that the body and the world play a

Causal Learning

Alison Gopnik

Learning about the causal structure of the world is a fundamental problem for human cognition. Over the past 20 years, cognitive scientists have applied advances in our understanding of causation in philosophy and computer science, particularly within the Causal Bayes Net formalism, to understand hu

Ritual

Richard Sosis

Rituals are patterns of behavior, ranging from handshakes that seal a business deal to singing anthems before sporting events and the hand-clasp greetings of chimpanzees. They include initiation rites, such as baptisms and bar mitzvahs, and they often demarcate major life events, such as weddings an

Sentence Processing

Matthew Wagers, Brian Dillon

Sentence processing is the study of how humans understand sentences. The central question is how we recognize and interpret compositional linguistic material—the larger, new expressions built up from smaller, familiar parts. Sentences are a major locus of novel composition, but so are phrases and ev

Supervenience

Karen Bennett

Philosophers and cognitive scientists sometimes say that one phenomenon obtains in virtue of some other phenomenon. While expressions like this can indicate causation, they are also frequently used in a more synchronic and constitutive way that suggests connections between phenomena at different “le

Developmental Cognitive Neuroscience

Hilary Richardson

Developmental cognitive neuroscientists study the baby, child, and adolescent brain to learn when and how cognition develops. Neuroscience techniques—electroencephalography (EEG), functional near-infrared spectroscopy (fNIRS), magnetoencephalography (MEG), and functional magnetic resonance imaging (

“The OECS has pulled off the magic trick of transforming The MIT Encyclopedia of the Cognitive Sciences into a renewed, dynamic online resource. The editors have thoughtfully focused on many of the most central topics in the field and have recruited key players to write well-crafted and informed entries. Supported by an excellent online interface run by The MIT Press, this constantly updated and expanding resource will become invaluable for the cognitive science community.”
— Robert A. Wilson and Frank C. Keil, co-editors of MITECS
“Systematically explore the science of the mind, or wander freely through its landmark topics––it’s your choice. Wherever you land in the OECS, you’ll find an authoritative yet accessible overview of key concepts and hot debates that make cognitive science an exciting field.”
