The magnification of the virtual image formed by the plane mirror is 1. Top: The formation of a virtual image using a diverging lens. Bottom: The formation of a virtual image using a convex mirror. In both diagrams, f is the focal point, O is the object, and I is the virtual image, shown in grey. Solid blue lines indicate (real) light rays and ...
Representationalism (also known as indirect realism) is the view that representations are the main way we access external reality.. The representational theory of mind attempts to explain the nature of ideas, concepts and other mental content in contemporary philosophy of mind, cognitive science and experimental psychology.
In the philosophy of mind, neuroscience, and cognitive science, a mental image is an experience that, on most occasions, significantly resembles the experience of "perceiving" some object, event, or scene but occurs when the relevant object, event, or scene is not actually present to the senses.
Psychologist E.R Jaensch states that eidetic memory as part of visual thinking has to do with eidetic images fading between the line of the after image and the memory image. [ citation needed ] A fine relationship may exist between the after image and the memory image, which causes visual thinkers from not seeing the eidetic image but rather ...
Visual object recognition refers to the ability to identify the objects in view based on visual input. One important signature of visual object recognition is "object invariance", or the ability to identify objects across changes in the detailed context in which objects are viewed, including changes in illumination, object pose, and background context.
The major problem in visual perception is that what people see is not simply a translation of retinal stimuli (i.e., the image on the retina), with the brain altering the basic information taken in. Thus people interested in perception have long struggled to explain what visual processing does to create what is actually seen.
The visual system is organized hierarchically, with anatomical areas that have specialized functions in visual processing. Low-level visual processing is concerned with determining different types of contrast among images projected onto the retina whereas high-level visual processing refers to the cognitive processes that integrate information from a variety of sources into the visual ...
According to Massumi in Parables for the Virtual, [8] the virtual is something "inaccessible to the senses" and can be felt in its effects. His definition goes on to explain virtuality through the use of a topological figure, in which stills of all of the steps in its transformation superposed would create a virtual image.
