What is configurational system?
In essence, Jody understands, a configurational system has to do not with what the features of a particular object or creature are, but with how these features are configured, or positioned, on the object. One important aspect of a configurational system has to do with spatial relationships.
What is Geon theory?
Geon theory assumes that objects are represented as an arrangement of simple, viewpoint-invariant, volumetric primitives (geons), such as bricks, cylinders, wedges, cones, and their curved axis counterparts.
What is feature analysis in the visual cortex?
The ability to perceive form, patterns, and objects not only results from the encoding of stimulus features by visual neurons (feature analysis), but is also under the influence of top-down processes.
What are templates in psychology?
the hypothesis that pattern recognition proceeds by comparing an incoming sensory stimulation pattern to mental images or representations of patterns (templates) until a match is found.
What is an example of perceptual learning?
perceptual learning, process by which the ability of sensory systems to respond to stimuli is improved through experience. Examples of perceptual learning include developing an ability to distinguish between different odours or musical pitches and an ability to discriminate between different shades of colours.
What is the meaning of Geon?
Filters. (physics) A hypothetical electromagnetic or gravitational wave held together in a confined region by the gravitational attraction of its own field energy. noun. (psychology) Any of a group of geometric forms capable of being recognised as a component of a real object.
What is a Geon in cognitive psychology?
Geons are the simple 2D or 3D forms such as cylinders, bricks, wedges, cones, circles and rectangles corresponding to the simple parts of an object in Biederman’s recognition-by-components theory. The theory proposes that the visual input is matched against structural representations of objects in the brain.
What is feature analysis?
Feature analysis argues that we observe individual characteristics, or features, of every object and pattern we encounter. Recognition-by-components theory maintains that we sort objects into their component parts as a way of recognizing them.
What is feature analysis in machine learning?
Feature selection is the process of reducing the number of input variables when developing a predictive model. It is desirable to reduce the number of input variables to both reduce the computational cost of modeling and, in some cases, to improve the performance of the model.
What is the difference between template and prototype?
As nouns the difference between template and prototype is that template is a physical object whose shape is used as a guide to make other objects while prototype is an original object or form which is a basis for other objects, forms, or for its models and generalizations.
What is the difference between template theories and feature matching theories?
Template analysis assumes that people form templates for every object they see or interact with and, therefore, fit what we see into what we already know. Feature analysis argues that we observe individual characteristics, or features, of every object and pattern we encounter.
