If you’re engrossed in an interesting video game, you may not notice other perceptual cues.

We also find salient information that interests us. Of course, many times, stimuli that meet our needs are also interesting, but it’s worth discussing these two items separately because sometimes we find things interesting that don’t necessarily meet our needs. I’m sure we’ve all gotten sucked into a television show, video game, or random project and paid attention to that at the expense of something that actually meets our needs like cleaning or spending time with a significant other. Paying attention to things that interest us but don’t meet specific needs seems like the basic formula for procrastination that we are all familiar with.

In many cases we know what interests us and we automatically gravitate toward stimuli that match up with that. For example, as you filter through radio stations, you likely already have an idea of what kind of music interests you and will stop on a station playing something in that genre while skipping right past stations playing something you aren’t interested in. Because of this tendency, we often have to end up being forced into or accidentally experiencing something new in order to create or discover new interests. For example, you may not realize you are interested in Asian history until you are required to take such a course and have an engaging professor who sparks that interest in you. Or you may accidentally stumble on a new area of interest when you take a class you wouldn’t otherwise because it fits into your schedule. As communicators, you can take advantage of this perceptual tendency by adapting your topic and content to the interests of your audience.

Expectations

The relationship between salience and expectations is a little more complex. Basically, we can find expected things salient and find things that are unexpected salient. While this may sound confusing, a couple examples should illustrate this point. If you are expecting a package to be delivered, you might pick up on the slightest noise of a truck engine or someone’s footsteps approaching your front door. Since we expect something to happen, we may be extra tuned in to clues that it is coming. In terms of the unexpected, if you have a shy and soft-spoken friend who you overhear raising the volume and pitch of his voice while talking to another friend, you may pick up on that and assume that something out of the ordinary is going on. For something unexpected to become salient, it has to reach a certain threshold of difference. If you walked into your regular class and there were one or two more students there than normal, you may not even notice. If you walked into your class and there was someone dressed up as a wizard, you would probably notice. So, if we expect to experience something out of the routine, like a package delivery, we will find stimuli related to that expectation salient. If we experience something that we weren’t expecting and that is significantly different from our routine experiences, then we will likely find it salient. We can also apply this concept to our communication. I always encourage my students to include supporting material in their speeches that defies our expectations. You can help keep your audience engaged by employing good research skills to find such information.

There is a middle area where slight deviations from routine experiences may go unnoticed because we aren’t expecting them. To go back to the earlier example, if you aren’t expecting a package, and you regularly hear vehicle engines and sidewalk foot traffic outside your house, those pretty routine sounds wouldn’t be as likely to catch your attention, even if it were slightly more or less traffic than expected. This is because our expectations are often based on previous experience and patterns we have observed and internalized, which allows our brains to go on “autopilot” sometimes and fill in things that are missing or overlook extra things. Look at the following sentence and read it aloud: Percpetoin is bsaed on pateetrns, maening we otfen raech a cocnlsuion witouht cosnidreing ecah indviidaul elmenet. This example illustrates a test of our expectation and an annoyance to every college student. We have all had the experience of getting a paper back with typos and spelling errors circled. This can be frustrating, especially if we actually took the time to proofread. When we first learned to read and write, we learned letter by letter. A teacher or parent would show us a card with A-P-P-L-E written on it, and we would sound it out. Over time, we learned the patterns of letters and sounds and could see combinations of letters and pronounce the word quickly. Since we know what to expect when we see a certain pattern of letters, and know what comes next in a sentence since we wrote the paper, we don’t take the time to look at each letter as we proofread. This can lead us to overlook common typos and spelling errors, even if we proofread something multiple times. As a side note, I’ll share two tips to help you avoid proofreading errors: First, have a friend proofread your paper. Since they didn’t write it, they have fewer expectations regarding the content. Second, read your papers backward. Since patterns of speech aren’t the same in reverse you have to stop and focus on each word. Now that we know how we select stimuli, let’s turn our attention to how we organize the information we receive.
