Cognitive science is the interdisciplinary, scientific study of the mind and its processes with input from linguistics, psychology, neuroscience, philosophy, computer science/artificial intelligence, and anthropology. It examines the nature, the tasks, and the functions of cognition. Cognitive scientists study intelligence and behavior, with a focus on how nervous systems represent, process, and transform information. 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 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."
Cognitive psychology is the scientific study of mental processes such as attention, language use, memory, perception, problem solving, creativity, and reasoning.
Perception is the organization, identification, and interpretation of sensory information in order to represent and understand the presented information or environment. All perception involves signals that go through the nervous system, which in turn result from physical or chemical stimulation of the sensory system. Vision involves light striking the retina of the eye; smell is mediated by odor molecules; and hearing involves pressure waves.
In psychology, affordance is what the environment offers the individual. In design, affordance has a narrower meaning, it refers to possible actions that an actor can readily perceive.
A sensorium (/sɛnˈsɔːrɪəm/) is the apparatus of an organism's perception considered as a whole, the "seat of sensation" where it experiences, perceives and interprets the environments within which it lives. The term originally entered English from the Late Latin in the mid-17th century, from the stem sens- ("sense"). In earlier use it referred, in a broader sense, to the brain as the mind's organ. In medical, psychological, and physiological discourse it has come to refer to the total character of the unique and changing sensory environments perceived by individuals. These include the sensation, perception, and interpretation of information about the world around us by using faculties of the mind such as senses, phenomenal and psychological perception, cognition, and intelligence.
Situated cognition is a theory that posits that knowing is inseparable from doing by arguing that all knowledge is situated in activity bound to social, cultural and physical contexts.
James Jerome Gibson was an American psychologist and is considered to be one of the most important contributors to the field of visual perception. Gibson challenged the idea that the nervous system actively constructs conscious visual perception, and instead promoted ecological psychology, in which the mind directly perceives environmental stimuli without additional cognitive construction or processing. A Review of General Psychology survey, published in 2002, ranked him as the 88th most cited psychologist of the 20th century, tied with John Garcia, David Rumelhart, Louis Leon Thurstone, Margaret Floy Washburn, and Robert S. Woodworth.
Perceptual psychology is a subfield of cognitive psychology that concerns the conscious and unconscious innate aspects of the human cognitive system: perception.
Behavior settings are theorized entities that help explain the relationship between individuals and the environment - particularly the social environment. This topic is typically indexed under the larger rubric of ecological psychology. However, the notion of behavior setting is offered here in more detail and with more specificity than is found in the larger entry under ecological psychology or environmental psychology.
A sensory cue is a statistic or signal that can be extracted from the sensory input by a perceiver, that indicates the state of some property of the world that the perceiver is interested in perceiving.
Embodied cognitive science is an interdisciplinary field of research, the aim of which is to explain the mechanisms underlying intelligent behavior. It comprises three main methodologies: the modeling of psychological and biological systems in a holistic manner that considers the mind and body as a single entity; the formation of a common set of general principles of intelligent behavior; and the experimental use of robotic agents in controlled environments.
Michael T. Turvey was the Board of Trustees' Distinguished Professor of Experimental Psychology at the University of Connecticut and a Senior Scientist at Haskins Laboratories in New Haven, Connecticut. He is best known for his pioneering work in ecological psychology and in applying the dynamical systems approach to the study of motor behavior. He was the founder of the Center for the Ecological Study of Perception and Action. His research spans a number of areas including: dynamic touch and haptics, interlimb coordination, visual perception and optic flow, postural stability, visual word recognition and speech perception. Along with William Mace and Robert Shaw, he was one of the leading explicators of the ecological psychology of J. J. Gibson. His pioneering work with J. A. Scott Kelso and Peter N. Kugler introduced the physical language of complex systems to the understanding of perception and action. He also helped introduce the ideas of the Russian motor control theorist Nikolai Bernstein and his colleagues to a larger audience. Working with Georgije Lukatela and other colleagues at Haskins Laboratories, he exploited the dual nature of the Serbo-Croatian orthography to help understand word recognition.
Systems psychology is a branch of both theoretical psychology and applied psychology that studies human behaviour and experience as complex systems. It is inspired by systems theory and systems thinking, and based on the theoretical work of Roger Barker, Gregory Bateson, Humberto Maturana and others. Groups and individuals are considered as systems in homeostasis. Alternative terms here are "systemic psychology", "systems behavior", and "systems-based psychology".
Wolfgang Prinz is a German cognitive psychologist. He is the director of the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig, Germany, and an internationally recognized expert in experimental psychology, cognitive psychology and philosophy of mind. He is the founder of the common coding theory between perception and action that has a significant impact in cognitive neuroscience and social cognition.
Common coding theory is a cognitive psychology theory describing how perceptual representations and motor representations are linked. The theory claims that there is a shared representation for both perception and action. More important, seeing an event activates the action associated with that event, and performing an action activates the associated perceptual event.
Some of the research that is conducted in the field of psychology is more "fundamental" than the research conducted in the applied psychological disciplines, and does not necessarily have a direct application. The subdisciplines within psychology that can be thought to reflect a basic-science orientation include biological psychology, cognitive psychology, neuropsychology, and so on. Research in these subdisciplines is characterized by methodological rigor. The concern of psychology as a basic science is in understanding the laws and processes that underlie behavior, cognition, and emotion. Psychology as a basic science provides a foundation for applied psychology. Applied psychology, by contrast, involves the application of psychological principles and theories yielded up by the basic psychological sciences; these applications are aimed at overcoming problems or promoting well-being in areas such as mental and physical health and education.
Action-specific perception, or perception-action, is a psychological theory that people perceive their environment and events within it in terms of their ability to act. This theory hence suggests that a person's capability to carry out a particular task affects how they perceive the different aspects and methods involved in that task. For example, softball players who are hitting better see the ball as bigger. Tennis players see the ball as moving slower when they successfully return the ball. In the field of human-computer interaction, alterations in accuracy impact both the perception of size and time, while adjustments in movement speed impact the perception of distance. Furthermore, the perceiver's intention to act is also critical; while the perceiver's ability to perform the intended action influences perception, the perceiver's abilities for unintended actions have little or no effect on perception. Finally, the objective difficulty of the task appears to modulate size, distance, and time perception.
Embodied cognition is the concept suggesting that many features of cognition are shaped by the state and capacities of the organism. The cognitive features include a wide spectrum of cognitive functions, such as perception biases, memory recall, comprehension and high-level mental constructs and performance on various cognitive tasks. The bodily aspects involve the motor system, the perceptual system, the bodily interactions with the environment (situatedness), and the assumptions about the world built the functional structure of organism's brain and body.
The Gibsonian ecological theory of development is a theory of development that was created by American psychologist Eleanor J. Gibson during the 1960s and 1970s. Gibson emphasized the importance of environment and context in learning and, together with husband and fellow psychologist James J. Gibson, argued that perception was crucial as it allowed humans to adapt to their environments. Gibson stated that "children learn to detect information that specifies objects, events, and layouts in the world that they can use for their daily activities". Thus, humans learn out of necessity. Children are information "hunter–gatherers", gathering information in order to survive and navigate in the world.
Cognitive ecology is the study of cognitive phenomena within social and natural contexts. It is an integrative perspective drawing from aspects of ecological psychology, cognitive science, evolutionary ecology and anthropology. Notions of domain-specific modules in the brain and the cognitive biases they create are central to understanding the enacted nature of cognition within a cognitive ecological framework. This means that cognitive mechanisms not only shape the characteristics of thought, but they dictate the success of culturally transmitted ideas. Because culturally transmitted concepts can often inform ecological decision-making behaviors, group-level trends in cognition are hypothesized to address ecologically relevant challenges.
