People who are able to form accurate first impressions tend to have more satisfying relationships and more quickly advance in their careers.

The old saying “You never get a second chance to make a good impression” points to the fact that first impressions matter. The brain is a predictive organ in that it wants to know, based on previous experiences and patterns, what to expect next, and first impressions function to fill this need, allowing us to determine how we will proceed with an interaction after only a quick assessment of the person with whom we are interacting.^[1] Research shows that people are surprisingly good at making accurate first impressions about how an interaction will unfold and at identifying personality characteristics of people they do not know. Studies show that people are generally able to predict how another person will behave toward them based on an initial interaction. People’s accuracy and ability to predict interaction based on first impressions vary, but people with high accuracy are typically socially skilled and popular and have less loneliness, anxiety, and depression; more satisfying relationships; and more senior positions and higher salaries.^[2] So not only do first impressions matter, but having the ability to form accurate first impressions seems to correlate to many other positive characteristics.

First impressions are enduring because of the primacy effect, which leads us to place more value on the first information we receive about a person. So if we interpret the first information we receive from or about a person as positive, then a positive first impression will form and influence how we respond to that person as the interaction continues. Likewise, negative interpretations of information can lead us to form negative first impressions. If you sit down at a restaurant and servers walk by for several minutes and no one greets you, then you will likely interpret that negatively and not have a good impression of your server when he finally shows up. This may lead you to be short with the server, which may lead him to not be as attentive as he normally would. At this point, a series of negative interactions has set into motion a cycle that will be very difficult to reverse and make positive.

The recency effect leads us to put more weight on the most recent impression we have of a person’s communication over earlier impressions. Even a positive first impression can be tarnished by a negative final impression. Imagine that a professor has maintained a relatively high level of credibility with you over the course of the semester. She made a good first impression by being organized, approachable, and interesting during the first days of class. The rest of the semester went fairly well with no major conflicts. However, during the last week of the term, she didn’t have final papers graded and ready to turn back by the time she said she would, which left you with some uncertainty about how well you needed to do on the final exam to earn an A in the class. When you did get your paper back, on the last day of class, you saw that your grade was much lower than you expected. If this happened to you, what would you write on the instructor evaluation? Because of the recency effect, many students would likely give a disproportionate amount of value to the professor’s actions in the final week of the semester, negatively skewing the evaluation, which is supposed to be reflective of the entire semester. Even though the professor only returned one assignment late, that fact is very recent in students’ minds and can overshadow the positive impression that formed many weeks earlier.

Physical and Environmental Influences on Perception

We make first impressions based on a variety of factors, including physical and environmental characteristics. In terms of physical characteristics, style of dress and grooming are important, especially in professional contexts. We have general schema regarding how to dress and groom for various situations ranging from formal, to business casual, to casual, to lounging around the house.

You would likely be able to offer some descriptors of how a person would look and act from the following categories: a goth person, a prep, a jock, a fashionista, a hipster. The schema associated with these various cliques or styles are formed through personal experience and through exposure to media representations of these groups. Different professions also have schema for appearance and dress. Imagine a doctor, mechanic, congressperson, exotic dancer, or mail carrier. Each group has clothing and personal styles that create and fit into general patterns. Of course, the mental picture we have of any of the examples above is not going to be representative of the whole group, meaning that stereotypical thinking often exists within our schema. We will learn more about the negative effects of stereotypical thinking later in the chapter, but it’s important to understand how persuasive various physical perceptual influences can be.

Think about the harm that has been done when people pose as police or doctors to commit crimes or other acts of malice. Seeing someone in a white lab coat automatically leads us to see that person as an authority figure, and we fall into a scripted pattern of deferring to the “doctor” and not asking too many questions. The Milgram experiments offer a startling example of how powerful these influences are. In the experiments, participants followed instructions from a man in a white lab coat (who was actually an actor), who prompted them to deliver electric shocks to a person in another room every time the other person answered a memory question incorrectly. The experiment was actually about how people defer to authority figures instead of acting independently. Although no one was actually being shocked in the other room, many participants continued to “shock,” at very high levels of voltage, the other person even after that person supposedly being shocked complained of chest pains and became unresponsive.^[3]

Clothing, like a doctor’s lab coat, forms powerful impressions that have noticeable effects on people’s behavior.

Just as clothing and personal style help us form impressions of others, so do physical body features. The degree to which we perceive people to be attractive influences our attitudes about and communication with them. Facial attractiveness and body weight tend to be common features used in the perception of physical attractiveness. In general people find symmetrical faces and nonoverweight bodies attractive. People perceived as attractive are generally evaluated more positively and seen as more kind and competent than people evaluated as less attractive. Additionally, people rated as attractive receive more eye contact, more smiles, and closer proximity to others (people stand closer to them). Unlike clothing and personal style, these physical features are more difficult, if not impossible, to change.

Finally, the material objects and people that surround a person influence our perception. In the MTV show Room Raiders, contestants go into the bedrooms of three potential dates and choose the one they want to go on the date with based on the impressions made while examining each potential date’s cleanliness, decorations, clothes, trophies and awards, books, music, and so on. Research supports the reliability of such impressions, as people have been shown to make reasonably accurate judgments about a person’s personality after viewing his or her office or bedroom.^[4] Although the artificial scenario set up in Room Raiders doesn’t exactly match up with typical encounters, the link between environmental cues and perception is important enough for many companies to create policies about what can and can’t be displayed in personal office spaces. It would seem odd for a bank manager to have an Animal House poster hanging in his office, and that would definitely influence customers’ perceptions of the manager’s personality and credibility. The arrangement of furniture also creates impressions. Walking into a meeting and sitting on one end of a long boardroom table is typically less inviting than sitting at a round table or on a sofa.

Although some physical and environmental features are easier to change than others, it is useful to become aware of how these factors, which aren’t necessarily related to personality or verbal and nonverbal communication, shape our perceptions. These early impressions also affect how we interpret and perceive later encounters, which can be further explained through the halo and horn effects.

The Halo and Horn Effects

We have a tendency to adapt information that conflicts with our earlier impressions in order to make it fit within the frame we have established. This is known as selective distortion, and it manifests in the halo and horn effects. The angelic halo and devilish horn are useful metaphors for the lasting effects of positive and negative impressions.

The halo effect occurs when initial positive perceptions lead us to view later interactions as positive. The horn effect occurs when initial negative perceptions lead us to view later interactions as negative.^[5] Since impressions are especially important when a person is navigating the job market, let’s imagine how the horn and halo effects could play out for a recent college graduate looking to land her first real job. Nell has recently graduated with her degree in communication studies and is looking to start her career as a corporate trainer. If one of Nell’s professors has a relationship with an executive at an area business, his positive verbal recommendation will likely result in a halo effect for Nell. Since the executive thinks highly of his friend the professor, and the professor things highly of Nell, then the executive will start his interaction with Nell with a positive impression and interpret her behaviors more positively than he would otherwise. The halo effect initiated by the professor’s recommendation may even lead the executive to dismiss or overlook some negative behaviors. Let’s say Nell doesn’t have a third party to help make a connection and arrives late for her interview. That negative impression may create a horn effect that carries through the interview. Even if Nell presents as competent and friendly, the negative first impression could lead the executive to minimize or ignore those positive characteristics, and the company may not hire her.
