A perceptual set, also called perceptual expectancy, is a predisposition to perceive things in a certain way. [1] Perceptual sets occur in all the different senses. [ 2 ] They can be long term, such as a special sensitivity to hearing one's own name in a crowded room, or short term, as in the ease with which hungry people notice the smell of ...
A perceptual set (also called perceptual expectancy or simply set) is a predisposition to perceive things in a certain way. [105] It is an example of how perception can be shaped by "top-down" processes such as drives and expectations. [106] Perceptual sets occur in all the different senses. [62]
An image schema (both schemas and schemata are used as plural forms) is a recurring structure within our cognitive processes which establishes patterns of understanding and reasoning. As an understudy to embodied cognition, image schemas are formed from our bodily interactions, [1] from linguistic
Multistable perception (or bistable perception) is a perceptual phenomenon in which an observer experiences an unpredictable sequence of spontaneous subjective changes. While usually associated with visual perception (a form of optical illusion ), multistable perception can also be experienced with auditory and olfactory percepts.
The complex wavelet transform variant of the SSIM (CW-SSIM) is designed to deal with issues of image scaling, translation and rotation. Instead of giving low scores to images with such conditions, the CW-SSIM takes advantage of the complex wavelet transform and therefore yields higher scores to said images. The CW-SSIM is defined as follows:
Figure–ground organization is a type of perceptual grouping that is a vital necessity for recognizing objects through vision. In Gestalt psychology it is known as identifying a figure from the background. For example, black words on a printed paper are seen as the "figure", and the white sheet as the "background". [1]
Mary Cheves West Perky (1874–1940) was an American psychologist and one of the twenty-one female students who studied under Edward B. Titchener at Cornell University.She received a Ph.D. in 1910 for her groundbreaking work on visual, auditory, and olfactory imagery.
Subjects are asked to recall each image clearly in their mind's eye. While recalling the images researchers are able view the areas activated by the visual memory task. Comparing the control 'baseline' state to the activated areas during the visual memory task allows researchers to view which areas are used during visual memory.
