Kratovaizdio

Kratovaizdio is a theoretical concept in the study of visual perception that refers to the set of brief, rapidly changing visual impressions produced by high-speed image streams. It is described as the experiential residue of fleeting stimuli that are presented too quickly to form stable, long‑lasting representations. In this framework, observers may retain a fragmentary sequence of images in short-term visual memory rather than a single, stable scene.

Origin of term: the word kratovaizdio is a neologism formed from elements meaning "short" and "image", intended to capture the idea of ephemeral visual scenes. The concept is not widely established in mainstream perception research and is mainly encountered in theoretical discussions and speculative literature.

Mechanisms: Proponents posit that kratovaizdio results from the interaction between rapid stimulus presentation, limited attentional resources, and short-term memory buffers. It would differ from iconic memory by emphasizing a fragmented sequence of impressions rather than a single preserved image, and from persistence of vision by focusing on discrete, transient images.

Applications and research: The notion is used in discussions of multimedia design, user interfaces, and virtual reality to describe perceptual limits under fast-changing visual content. Empirical validation is limited; studies would typically employ rapid serial visual presentation tasks, masking, and memory reporting to ascertain the fidelity and duration of kratovaizdio impressions.
