ABSTRACT
A dynamic pattern can originate in several ways. In the memory of an observer, a dynamic pattern coming from the outside world may begin in the preliminary integration of the retinal mosaic. It would then meet the appropriate mnemonic potentials, be recognized, identified, and integrated. For a writer, in addition to dynamic patterns from the outside world, memory may also create dynamic patterns from fragments of other dynamic patterns that were processed during reading or conversation. This phenomenon has been called echo. Thus, many literary dynamic patterns owe their existence to the process of retrieval during which writers or speakers recall fragments or whole patterns they have heard or read in the past and use them to create new patterns and a new text. The retrieved patterns or fragments may lead a writer to produce new thoughts and images or, on the other hand, new perceptions and thoughts may act as cues to retrieve the old patterns.
