Interpreting Information

Although selecting and organizing incoming stimuli happens very quickly, and sometimes without much conscious thought, interpretation can be a much more deliberate and conscious step in the perception process. Interpretation is the third part of the perception process, in which we assign meaning to our experiences using mental structures known as schemata. Schemata are like databases of stored, related information that we use to interpret new experiences. We all have fairly complicated schemata that have developed over time as small units of information combine to make more meaningful complexes of information.

We have an overall schema about education and how to interpret experiences with teachers and classmates. This schema started developing before we even went to preschool based on things that parents, peers, and the media told us about school. For example, you learned that certain symbols and objects like an apple, a ruler, a calculator, and a notebook are associated with being a student or teacher. You learned new concepts like grades and recess, and you engaged in new practices like doing homework, studying, and taking tests. You also formed new relationships with teachers, administrators, and classmates. As you progressed through your education, your schema adapted to the changing environment. How smooth or troubling schema reevaluation and revision is varies from situation to situation and person to person. For example, some students adapt their schema relatively easily as they move from elementary, to middle, to high school, and on to college and are faced with new expectations for behavior and academic engagement. Other students don’t adapt as easily, and holding onto their old schema creates problems as they try to interpret new information through old, incompatible schema. We’ve all been in a similar situation at some point in our lives, so we know that revising our schemata can be stressful and that such revision takes effort and usually involves some mistakes, disappointments, and frustrations. But being able to adapt our schemata is a sign of cognitive complexity, which is an important part of communication competence. So, even though the process may be challenging, it can also be a time for learning and growth.

It’s important to be aware of schemata because our interpretations affect our behavior. For example, if you are doing a group project for class and you perceive a group member to be shy based on your schema of how shy people communicate, you may avoid giving him presentation responsibilities in your group project because you do not think shy people make good public speakers. Schemata also guide our interactions, providing a script for our behaviors. We know, in general, how to act and communicate in a waiting room, in a classroom, on a first date, and on a game show. Even a person who has never been on a game show can develop a schema for how to act in that environment by watching The Price Is Right, for example. People go to great lengths to make shirts with clever sayings or act enthusiastically in hopes of being picked to be a part of the studio audience and hopefully become a contestant on the show.

As we have seen, schemata are used to interpret others’ behavior and form impressions about who they are as a person. To help this process along, we often solicit information from people to help us place them into a preexisting schema. In the United States and many other Western cultures, people’s identities are often closely tied to what they do for a living. When we introduce others, or ourselves, occupation is usually one of the first things we mention. Think about how your communication with someone might differ if he or she were introduced to you as an artist versus a doctor. We make similar interpretations based on where people are from, their age, their race, and other social and cultural factors. We will learn more about how culture, gender, and other factors influence our perceptions as we continue through the chapter. In summary, we have schemata about individuals, groups, places, and things, and these schemata filter our perceptions before, during, and after interactions. As schemata are retrieved from memory, they are executed, like computer programs or apps on your smartphone, to help us interpret the world around us. Just like computer programs and apps must be regularly updated to improve their functioning, competent communicators update and adapt their schemata as they have new experiences.

“Getting Real”

Police Officers, Schemata, and Perception/Interpretation

Prime-time cable and network television shows like the Law and Order franchise and Southland have long offered viewers a glimpse into the lives of law enforcement officers. COPS, the first and longest-running prime-time reality television show, and newer reality-themed and educational shows like The First 48 and Lockdown, offer a more realistic look into techniques used by law enforcement. Perception is a crucial part of an officer’s skill set. Specifically, during police-citizen encounters, where tensions may be high and time for decision making limited, officers rely on schemata developed through personal experience off the job and training and experience on the job. Richard M. Rozelle and James C. Baxter, “Impression Formation and Danger Recognition in Experienced Police Officers,” Journal of Social Psychology 96 (1975): 54. Moreover, police officers often have to make perceptions based on incomplete and sometimes unreliable information. So, how do police officers use perception to help them do their jobs?

Research has examined how police officers use perception to make judgments about personality traits, credibility, deception, and the presence or absence of a weapon, among others things, and just like you and me, officers use the same process of selection, organization, and interpretation. This research has found that officers, like us, rely on schema to help them make decisions under time and situational constraints. In terms of selection, expectations influence officer perception. At preshift meetings, officers are briefed on ongoing issues and “things to be on the lookout for,” which provides them with a set of expectations—for example, the make and model of a stolen car—that can guide their selection process. They must also be prepared for things that defy their expectations, which is not a job skill that many other professionals have to consider every day. They never know when a traffic stop could turn into a pursuit or a seemingly gentle person could turn violent. These expectations can then connect to organization strategies. For example, if an officer knows to be alert for a criminal suspect, they will actively organize incoming perceptual information into categories based on whether or not people look similar to or different from the suspect description. Proximity also plays into police work. If a person is in a car with a driver who has an unregistered handgun, the officer is likely to assume that the other person also has criminal intent. While these practices are not inherently bad, there are obvious problems that can develop when these patterns become rigid schema. Some research has shown that certain prejudices based on racial schema can lead to perceptual errors—in this case, police officers mistakenly perceiving a weapon in the possession of black suspects more often than white suspects. B. Keith Payne, “Prejudice and Perception: The Role of Automatic and Controlled Processes in Misperceiving a Weapon,” Journal of Personality and Social Psychology 81, no. 2 (2001): 181–92. Additionally, racial profiling (think of how profiles are similar to schemata) has become an issue that’s gotten much attention since the September 11, 2001, terrorist attacks and the passage of immigration laws in states like Arizona and Alabama that have been critiqued as targeting migrant workers and other undocumented immigrants. As you can see, law enforcement officers and civilians use the same perception process, but such a career brings with it responsibilities and challenges that highlight the imperfect nature of the perception process.

1. What communication skills do you think are key for a law enforcement officer to have in order to do their job effectively and why?
2. Describe an encounter that you have had with a law enforcement officer (if you haven’t had a direct experience you can use a hypothetical or fictional example). What were your perceptions of the officer? What do you think his or her perceptions were of you? What schemata do you think contributed to each of your interpretations?
3. What perceptual errors create potential ethical challenges in law enforcement? For example, how should the organizing principles of proximity, similarity, and difference be employed?

KEY TAKEAWAYS

• Perception is the process of selecting, organizing, and interpreting information. This process affects our communication because we respond to stimuli differently, whether they are objects or persons, based on how we perceive them.
• Given the massive amounts of stimuli taken in by our senses, we only select a portion of the incoming information to organize and interpret. We select information based on salience. We tend to find salient things that are visually or aurally stimulating and things that meet our needs and interests. Expectations also influence what information we select.
• We organize information that we select into patterns based on proximity, similarity, and difference.
• We interpret information using schemata, which allow us to assign meaning to information based on accumulated knowledge and previous experience.

EXERCISES

1. Take a moment to look around wherever you are right now. Take in the perceptual field around you. What is salient for you in this moment and why? Explain the degree of salience using the three reasons for salience discussed in this section.
2. As we organize information (sensory information, objects, and people) we simplify and categorize information into patterns. Identify some cases in which this aspect of the perception process is beneficial. Identify some cases in which it could be harmful or negative.
3. Getting integrated: Think about some of the schemata you have that help you make sense of the world around you. For each of the following contexts—academic, professional, personal, and civic—identify a schema that you commonly rely on or think you will rely on. For each schema you identified note a few ways that it has already been challenged or may be challenged in the future.
