When perceiving external information, one must be aware of three magic letters that represent the processes into which this overall process of perception is broken down. These letters are P, R, and S, which stand for the words “Parsing,” “Recognition,” and “Structuring,” respectively.
In psychology, the description of the process of perceiving external information is conventionally divided into perception and apperception – the primary sensory perception and the logical level that follows sensory perception.
However, this division is rather arbitrary and is not suitable for the algorithmic construction of perception. Therefore, three magic letters were introduced to make the process more understandable. Moreover, these letter-processes are so closely related that they are intertwined and can appear one after another many times.
For example, when we parse a text, we separate words during perception. Some very long words have to be structured (parts of the word are extracted) and templates (which relates to recognition) are applied based on existing words. And this process can continue.
The result of recognition should be a congruent (related to your existing concepts) and structured result, for example, in the form of a tree, of images, words, or other elements – primitives or granules – used in the description.
