Visual and Aural Stimulation

It is probably not surprising to learn that visually and/or aurally stimulating things become salient in our perceptual field and get our attention. Creatures ranging from fish to hummingbirds are attracted to things like silver spinners on fishing poles or red and yellow bird feeders. Having our senses stimulated isn’t always a positive thing though. Think about the couple that won’t stop talking during the movie or the upstairs neighbor whose subwoofer shakes your ceiling at night. In short, stimuli can be attention-getting in a productive or distracting way. As communicators, we can use this knowledge to our benefit by minimizing distractions when we have something important to say. It’s probably better to have a serious conversation with a significant other in a quiet place rather than a crowded food court. As we will learn later in Chapter 12 "Public Speaking in Various Contexts", altering the rate, volume, and pitch of your voice, known as vocal variety, can help keep your audience engaged, as can gestures and movement. Conversely, nonverbal adaptors, or nervous movements we do to relieve anxiety like pacing or twirling our hair, can be distracting. Aside from minimizing distractions and delivering our messages enthusiastically, the content of our communication also affects salience.
