| | Visual perception - Wikipedia, the free encyclopedia |
 | | The eye's retina performs the first stages of visual perception processing, with the remaining stages of visual perception occurring in the optic nerve, the lateral geniculate nucleus, and the visual cortex of the brain. | | | Models based on this idea have been used to describe various visual subsystems, such as the perception of motion or the perception of depth. | | | The unconscious inference hypothesis has recently been revived in so-called Bayesian studies of visual perception. |

| | Minding the gap: visual perception and cinematic gap filling.(Critical Essay) - Style - HighBeam Research |
| | Visual reorganization works by our being able to retrieve images from memory, images that may not have been classified and categorized at the time of perception, but are being determined at the time of this later cognitive operation, the one of gap filling. | | | But attentiveness to visual detail and the ability to refocus and reinterpret it when the narrative conditions change are both keys to the success of the gap-filling practices of this scene. | | | The dramatic information in the scene is conveyed almost entirely by visual means (there are a couple of verbal exchanges between the father and mother, but they are not very informative, for the father doesn't tell her what he thinks he heard or why he is up). |

| | Historical Notes: History [of visual perception] |
| | Studies of visual illusions around the end of the 1800s raised many questions that were not readily amenable to numerical measurement or traditional mathematical analysis, and this led in part to the Gestalt approach to psychology which attempted to formulate various global principles of visual perception. | | | Visual perception has been used for centuries as an example in philosophical discussions about the nature of experience. | | | At first it was thought that the visual system might be sensitive only to the overall autocorrelation of an image, given by the probability that randomly selected points have the same color. |

| | Explorations of this latter question have ranged from studies of the anatomy and physiology of single nerve cells in the visual cortex to investigations of visual discrimination behavior in individual animals. | | | In an attempt to isolate the early visual mechanisms responsible for registering and discriminating object surfaces and edges, my colleagues and I have been investigating the phenomenon of perceptual grouping in pigeons and humans by testing them with different types of multi-element visual stimuli. | | | This ability of nervous systems to construct internal visual representations of the outside world represents one of the most important milestones in the evolution of animal behavior and cognition. |

| | Visual Perception |
| | Gestalt psychology is a movement in experimental psychology that began just prior to World War I. It made important contributions to the study of visual perception and problem solving. | | | The focal point of Gestalt theory is the idea of "grouping," or how we tend to interpret a visual field or problem in a certain way. | | | Gestalt theory applies to all aspects of human learning, although it applies most directly to perception and problem-solving. |

| | SOLVING THE "REAL" MYSTERIES OF VISUAL PERCEPTION: |
| | Even though classic visual phenomena like the illusions and effects displayed in science museums and the specific domains currently discussed by visual scientists, such as colour vision, stereopsis, movement perception, contrast sensitivity, etc., are important and interesting, they are in a way just the tip of the iceberg in the task of understanding vision. | | | The idea of visual perception involving component extraction is also compatible with Ivo Kohler's (1951) findings, according to which after training with spectacles that transform the visual world in various ways (inverting, reflecting), subjects re-establish normal upright perception in a fragmentary way, with aspects of the environment being corrected, and others not. | | | My tactile perception of the bottle is provided by my exploration of it with my fingers, that is by the sequence of changes in sensation that are provoked by this exploration, and by the relation between the changes that occur and my knowledge about what bottles are like. |

| | IntelligentEnterprise : Data Presentation: Tapping the Power of Visual Perception (printable version) |
| | Perception of these basic visual attributes is called "preattentive" processing, in contrast to the conscious part of perception, which is called "attentive" processing. | | | Preattentive processing is extremely fast and broadband in that we can simultaneously perceive a large number of these basic visual attributes, called "preattentive attributes." Preattentive perception is done in parallel, but attentive processing is done serially and is, therefore, much slower. | | | I believe that most people perform better at their jobs, even jobs that are seemingly mundane, when they understand what works, what doesn't, and why. |

| | Webvision: Visual Cortex |
| | For over 80 years Gestalt psychologists have argued that the act of perception creates a Gestalt, a figure or form that is not a property of an object observed but represents the organization of sensations by the brain (Kandel, 1991, p441]. | | | Anatomical hierarchical models place the visual cortical areas into a multi-level processing model based upon the pattern of feedforward, lateral, and feedback pathways found in each area. | | | It is the hope of many researchers, myself included, that a careful investigation into the structure and function of the visual pathways using chemical, electrophysiological, genetic, and behavioural approaches will culminate in a true understanding of how the brain provides us with this most crucial of sensory capabilities, vision. |

| | We conjecture that the dividing line between these two families of visual modules comes with the perception of visual edges, so that the 'early' mechanisms could also be characterized as 'edge independent' and the 'late' mechanisms as 'edge dependent'. | | | The visual phenomena explored in this paper and its predecessor confirm and sharpen a theoretical view of the 'pre-gestalt' processes of the visual system. | | | We present one more figure to confirm the fact that insertion of a roughly 120ms delay does not disrupt the perception of phi motion, which belongs to our family of 'late' processes, nearly as much as it does Glass swirl perception. |

| | Recent studies conducted by the LaRA have shown that local and global perception and the development of local and global representations is typical in individuals with autism, as is configural processing. | | | A recent finding in the LaRA, which may be related to this issue, is that children with autism process dynamic stimuli differently to static stimuli. | | | One suggestion has been that individuals with autism show enhanced perception of individual features and/or poor perception of global configural stimuli. |

| | Imagination Can Enhance Visual Perception |
| | The institute researchers have, for the first time, quantified the effects of visual imagery on perception by creating experiments in which subjects viewed subtle points of light, known as Gabor signals, on a computer screen. | | | However, imagination greases the wheels of perception only when the images are drawn from short-term memory, the researchers report in the current issue of the Journal of Cognitive Neuroscience. | | | "It seems that, under certain circumstances, activating short-term memory can change the hard wiring of the visual cortex, allowing people to see what they couldn't see before," said Dr. Alumit Ishai, who conducted this research during her doctoral studies under the guidance of professor Dov Sagi of the Weizmann Institute's Neurobiology Department. |

| | J Goguen Review of *Visual Space Perception* by M Hershenson |
| | The knowledge associated to an affordance cannot be captured by passive predicates, and even the currently popular paradigm of active perception does not capture its essence; both perception and action are better understood in terms of affordances. | | | This book is a good survey of a large body of important work in the experimental psychology of visual space perception. | | | A starting point would be the observation that seeing involves the deployment of complex sensory-motor schemata that embody important learned relationships; for this reason, spatial perception should be understood in terms of the affordances that are involved in actually doing spatial perception. |
