Ensemble Coding
Ensemble coding, also known as ensemble perception or summary representation, is a theory in cognitive neuroscience about the internal representation of groups of objects in the human mind. Ensemble coding proposes that such information is recorded via summary statistics, particularly the average or variance. Experimental evidence tends to support the theory for low-level visual information, such as shapes and sizes, as well as some high-level features such as face gender. Nonetheless, it remains unclear the extent to which ensemble coding applies to high-level or non-visual stimuli, and the theory remains the subject of active research. Theory Extensive amounts of information are available to the visual system. Ensemble coding is a theory that suggests that people process the general gist of their complex visual surroundings by grouping objects together based on shared properties. The world is filled with redundant information of which the human visual system has become part ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cognitive Neuroscience
Cognitive neuroscience is the scientific field that is concerned with the study of the biological processes and aspects that underlie cognition, with a specific focus on the neural connections in the brain which are involved in mental processes. It addresses the questions of how cognitive activities are affected or controlled by neural circuits in the brain. Cognitive neuroscience is a branch of both neuroscience and psychology, overlapping with disciplines such as behavioral neuroscience, cognitive psychology, physiological psychology and affective neuroscience.Gazzaniga 2002, p. xv Cognitive neuroscience relies upon theories in cognitive science coupled with evidence from neurobiology, and computational modeling. Parts of the brain play an important role in this field. Neurons play the most vital role, since the main point is to establish an understanding of cognition from a neural perspective, along with the different lobes of the cerebral cortex. Methods employed in c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Change Blindness
Change blindness is a perceptual phenomenon that occurs when a change in a visual stimulus is introduced and the observer does not notice it. For example, observers often fail to notice major differences introduced into an image while it flickers off and on again. People's poor ability to detect changes has been argued to reflect fundamental limitations of human attention. Change blindness has become a highly researched topic and some have argued that it may have important practical implications in areas such as eyewitness testimony and distractions while driving. History Early anecdotal observations Outside of the domain of psychology, phenomena related to change blindness have been discussed since the 19th century. When film editing was introduced in movies, editors began to notice that changes to the background were not noticed by those watching the film. Going back earlier, William James (1842–1910) was the first to mention the lack of ability to detect change in his book ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cognitive Psychology
Cognitive psychology is the scientific study of mental processes such as attention, language use, memory, perception, problem solving, creativity, and reasoning. Cognitive psychology originated in the 1960s in a break from behaviorism, which held from the 1920s to 1950s that unobservable mental processes were outside the realm of empirical science. This break came as researchers in linguistics and cybernetics, as well as applied psychology, used models of mental processing to explain human behavior. Work derived from cognitive psychology was integrated into other branches of psychology and various other modern disciplines like cognitive science, linguistics, and economics. The domain of cognitive psychology overlaps with that of cognitive science, which takes a more interdisciplinary approach and includes studies of non-human subjects and artificial intelligence. History Philosophically, ruminations on the human mind and its processes have been around since the times of the a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Social Vision
Social vision is a sub-topic of social psychology that investigates the ways from which individuals extract information and perceive others using their vision alone. The field of social vision is highly interdisciplinary and located at the nexus of social psychology, communication studies, and vision science.Johnson, K. L., & Adams, R. B. (2013). Social Vision: An introduction. ''Social Cognition, 31'' (6), 633-635. Much of the research in social vision is based on the prevailing theory that the visual system is particularly attuned to social cues in the environment. More of the human brain is devoted to vision than all other senses combined, and social vision research seeks to understand how humans are able to use vision to accurately perceive characteristics of other individuals such as age, race, gender, and sexual orientation in a short time frame as well as how individual beliefs may bias the way humans perceive said individuals. Historical development Social vision was dev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
High- And Low-level
High-level and low-level, as technical terms, are used to classify, describe and point to specific goals of a systematic operation; and are applied in a wide range of contexts, such as, for instance, in domains as widely varied as computer science and business administration. High-level describe those operations that are more abstract in nature; wherein the overall goals and systemic features are typically more concerned with the wider, macro system as a whole. Low-level describes more specific individual components of a systematic operation, focusing on the details of rudimentary micro functions rather than macro, complex processes. Low-level classification is typically more concerned with individual components within the system and how they operate. Features which emerge only at a high level of description are known as epiphenomena. Differences Due to the nature of complex systems, the high-level description will often be completely different from the low-level one; and, the ...

Impression Formation
Impression formation in social psychology refers to the processes by which different pieces of knowledge about another are combined into a global or summary impression. Social psychologist Solomon Asch is credited with the seminal research on impression formation and conducted research on how individuals integrate information about personality traits. Two major theories have been proposed to explain how this process of integration takes place. The Gestalt approach views the formation of a general impression as the sum of several interrelated impressions. As an individual seeks to form a coherent and meaningful impression of another individual, previous impressions significantly influence the interpretation of subsequent information. In contrast to the Gestalt approach, the cognitive algebra approach asserts that individuals' experiences are combined with previous evaluations to form a constantly changing impression of a person. A related area to impression formation is the study of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gestalt Psychology
Gestalt-psychology, gestaltism, or configurationism is a school of psychology that emerged in the early twentieth century in Austria and Germany as a theory of perception that was a rejection of basic principles of Wilhelm Wundt's and Edward Titchener's elementalist and structuralist psychology.Mather, George (2006) Foundations of Perception, Psychology Pressch.1 p.32 As used in Gestalt psychology, the German word ''Gestalt'' ( , ; meaning "form") is interpreted as "pattern" or "configuration". Gestalt psychologists emphasize that organisms perceive entire patterns or configurations, not merely individual components. The view is sometimes summarized using the adage, "the whole is more than the sum of its parts." Gestalt psychology was founded on works by Max Wertheimer, Wolfgang Köhler, and Kurt Koffka. Origin and history Max Wertheimer (1880–1943), Kurt Koffka (1886–1941), and Wolfgang Köhler (1887-1967) founded Gestalt psychology in the early 20th century. The domi ...

Gestalt Grouping Rules
The principles of grouping (or Gestalt laws of grouping) are a set of principles in psychology, first proposed by Gestalt psychologists to account for the observation that humans naturally perceive objects as organized patterns and objects, a principle known as Prägnanz. Gestalt psychologists argued that these principles exist because the mind has an innate disposition to perceive patterns in the stimulus based on certain rules. These principles are organized into five categories: Proximity, Similarity, Continuity, Closure, and Connectedness. Irvin Rock and Steve Palmer, who are acknowledged as having built upon the work of Max Wertheimer and others and to have identified additional grouping principles, note that Wertheimer's laws have come to be called the "Gestalt laws of grouping" but state that "perhaps a more appropriate description" is "principles of grouping." Rock and Palmer helped to further Wertheimer's research to explain human perception of groups of objects and how ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vision Science
Vision science is the scientific study of visual perception. Researchers in vision science can be called vision scientists, especially if their research spans some of the science's many disciplines. Vision science encompasses all studies of vision, such as how human and non-human organisms process visual information, how conscious visual perception works in humans, how to exploit visual perception for effective communication, and how artificial systems can do the same tasks. Vision science overlaps with or encompasses disciplines such as ophthalmology and optometry, neuroscience(s), psychology (particularly sensation and perception psychology, cognitive psychology, linguistics, biopsychology, psychophysics, and neuropsychology), physics (particularly optics), ethology, and computer science (particularly computer vision, artificial intelligence, and computer graphics), as well as other engineering related areas such as data visualization, user interface design, and human factors and ...

Human Mind
The mind is the set of faculties responsible for all mental phenomena. Often the term is also identified with the phenomena themselves. These faculties include thought, imagination, memory, will, and sensation. They are responsible for various mental phenomena, like perception, pain experience, belief, desire, intention, and emotion. Various overlapping classifications of mental phenomena have been proposed. Important distinctions group them according to whether they are ''sensory'', ''propositional'', ''intentional'', ''conscious'', or ''occurrent''. Minds were traditionally understood as substances but it is more common in the contemporary perspective to conceive them as properties or capacities possessed by humans and higher animals. Various competing definitions of the exact nature of the mind or mentality have been proposed. ''Epistemic definitions'' focus on the privileged epistemic access the subject has to these states. ''Consciousness-based approaches'' give primacy to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
