Phase 3 – discrimination between symbols: As soon as the student has demonstrated distance and persistence in multiple settings with multiple communicative partners, they are ready to be introduced to phase 3A – visual discrimination. During structured training sessions, the student will begin to work on discriminating between highly ...
Persistence of vision is the optical illusion that occurs when the visual perception of an object does not cease for some time after the rays of light proceeding from it have ceased to enter the eye. [1] The illusion has also been described as "retinal persistence", [2] "persistence of impressions", [3] simply "persistence" and other variations ...

Picture Communication Exchange System (PECS) is a commonly used low-tech communication system that teach individuals how to request, comment, and answer questions through the use of line drawings known as Picture Communication Symbols (PCS). Symbols are placed in fixed position on the screen which allow users to develop motor patterns ...
A 1-interleaving between two -indexed persistence modules M and N, represented as a diagram of vector spaces and linear maps between them.. In topological data analysis, the interleaving distance is a measure of similarity between persistence modules, a common object of study in topological data analysis and persistent homology.
[3] Claudet also noted in 1867 that the thaumatrope could create a three-dimensional illusion. A spinning rectangular thaumatrope with the alternating letters of the name "Victoria" on each side, showed the full word with the letters at two different distances from the observer's eye. If the two strings of the thaumatrope are attached to the ...
A 2-distance set is a set of points for which the set of distinct mutual distances has cardinality exactly 2. An example of a 2-distance set is the set of vertices of the regular octahedron. There are various results about 2-distance sets, including a classification of all 2-distance sets in dimension 4. [8] Every 2-distance set is an isosceles ...
