liiannostosekunnin

liiannostosekunnin is a term used in speculative fiction and worldbuilding to denote a perceptual-cognitive phenomenon in which sustained rapid sensory stimulation causes a distortion of time perception, often described as the compression or dilation of seconds, with accompanying changes in reaction speed and decision-making.

Etymology: The term is constructed from elements in the Liian lexicon, combining liian meaning “excessive” or “beyond” and nostosekun referring to “moment” or “second.” The coinage appears in Liian cultural texts and is used across several speculative works to designate the phenomenon.

In-universe mechanism: The contemporary theory posits a resonance in neural timing circuits where heightened arousal and transient shifts in attention bind successive short time intervals into a single perceptual unit. It is described as a “time fragment” effect and is reported to occur during high-stakes tasks such as piloting or close-quarters operation in fiction, causing people to react either more slowly or more quickly depending on context.

History and usage: First described in the Liian Encyclopedia of Cognitive Phenomena (2147) by researcher Dr. Mira Kaal, the concept has since appeared in novels, games, and role-playing sourcebooks as a plot device or modeling assumption. It is often used to explore themes of perception under pressure and the limits of human attention.

Real-world status: As a fictional construct, liiannostosekunnin has no basis in established real-world neuroscience; it functions as a narrative and theoretical tool within its fictional spheres.
