percepní

Percepní is a Czech adjective used to denote something that relates to perception or perceptual processes. It is commonly employed in fields that study how sensory information is received, interpreted, and organized, such as psychology, philosophy, cognitive science, and design. In practice, percepní describes aspects tied to the intake and processing of sensory data rather than to memory, decision making, or action, which are categorized under other cognitive domains.

Etymology and spelling notes: percepní is derived from the Czech noun percepce (perception) with the adjectival suffix -ní. The normative form in contemporary standard Czech is percepční, spelled with the diacritic č. The variant percepní appears in contexts where diacritics are omitted or in nonstandard spellings, and it carries the same basic meaning as percepční.

Usage and examples: the term appears in phrases such as percepční procesy (perceptual processes), percepční iluze (perceptual illusion), and percepční systém (perceptual system). It is used to distinguish perceptual aspects from other cognitive or motor functions, and it often appears alongside related terms like vnímání (sensing/perception) and kognitivní (cognitive).
