In the context of selective attention, salience refers to which statement?

• A. It refers to how we expect to encounter information
• B. It refers to how much a stimulus stands out and captures attention
• C. It refers to rate of information processing
• D. It refers to the effort required to perform a task

Answer: (B)

In selective attention, salience is about how much a stimulus stands out from its surroundings and automatically grabs attention. It’s driven by the stimulus’s inherent properties—bright colors, high contrast, loud sounds, motion, or novelty—so something salient can capture attention even if you’re not consciously aiming to notice it. This bottom-up capture helps clinicians notice important alerts or abnormalities on a monitor, but it also means too many salient signals can lead to alarm fatigue, so interface design should make critical information stand out without overwhelming you.

The other statements don’t describe salience: it’s not about what you expect to encounter (top-down expectations), nor about how fast information is processed, nor about the effort required to perform a task.
