Emission theory or extramission theory (variants: extromission) or extromissionism is the proposal that visual perception is accomplished by eye beams emitted by the eyes. This theory has been replaced by intromission theory (or intromissionism ), which is that visual perception comes from something representative of the object (later ...
The name most often associated with emission theory is Isaac Newton.In his corpuscular theory Newton visualized light "corpuscles" being thrown off from hot bodies at a nominal speed of c with respect to the emitting object, and obeying the usual laws of Newtonian mechanics, and we then expect light to be moving towards us with a speed that is offset by the speed of the distant emitter (c ± v).
There were two major ancient Greek schools, providing a primitive explanation of how vision works. The first was the "emission theory" of vision which maintained that vision occurs when rays emanate from the eyes and are intercepted by visual objects. If an object was seen directly it was by 'means of rays' coming out of the eyes and again ...
Emission theory may refer to: Emission theory (relativity), a former competing theory for the special theory of relativity; Emission theory (vision), ...
Robert Frank Mager [meɪgɜ:] (June 10, 1923 – May 23, 2020) was an American psychologist and author. Concerned with understanding and improving human performance, he is known for developing a framework for preparing learning objectives, and criterion referenced instruction (CRI), as well as addressing areas of goal orientation, student evaluation, student motivation, classroom environment ...
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 taxonomy divides learning objectives into three broad domains: cognitive (knowledge-based), affective (emotion-based), and psychomotor (action-based), each with a hierarchy of skills and abilities. These domains are used by educators to structure curricula, assessments, and teaching methods to foster different types of learning.
The interpretation in (Winer et al., 2002) of the answers was that if the subject's answers indicated that the subject thought something emitted from the eyes at all for vision to work (even if something also entered the eye), then it counted as a de facto belief in emission theory (IMO, "belief" is a perhaps too strong an interpretation).
