Näitude

Näitude is a theoretical construct used in cognitive science, design studies, and media theory to quantify the perceptual salience or prominence of a stimulus within a given context. It describes how readily a feature stands out to a perceiver relative to competing stimuli, goals, and expectations. The term is a neologism built to convey degree, and is used to discuss visibility, noticeability, and attentional capture across modalities. A näitude index is often treated as a dimensionless quantity on a 0 to 1 scale, where values near 1 indicate high perceptual prominence and values near 0 indicate low prominence.

Measurement and interpretation: Researchers propose combining psychophysical tasks, eye-tracking data, reaction times, and self-report to assess näitude. Factors that raise näitude include greater sensory intensity, higher contrast, longer duration, and alignment with user goals; factors that reduce it include distraction, context variability, and competing salient features. Näitude is highly context-dependent and can vary across tasks and users.

Applications: In user-interface design, advertising, education, and information visualization, näitude helps explain why certain elements attract attention more readily than others. Examples: a blinking red alert in a safety app may have high näitude, whereas a subtle logo watermark has low näitude.

Limitations: The concept is informal and lacks standardized measurement methods or normative benchmarks. Subjectivity, cultural differences, and changing contexts complicate comparison across studies. As such, näitude is best used as a descriptive heuristic rather than an objective metric until consensus emerges.

Status: The term appears in contemporary design and rhetoric rather than in formal peer-reviewed literature, and is occasional shorthand for discussing salience and attentional capture. See also: salience, conspicuity, prominence.
