We can begin to classify key relationships we have by distinguishing between our personal and our social relationships (VanLear, Koerner, & Allen, 2006). Personal relationships meet emotional, relational, and instrumental needs, as they are intimate, close, and interdependent relationships such as those we have with best friends, partners, or immediate family. Social relationships are relationships that occasionally meet our needs and lack the closeness and interdependence of personal relationships. Examples of social relationships include coworkers, distant relatives, and acquaintances. Another distinction useful for categorizing relationships is whether or not they are voluntary. For example, some personal relationships are voluntary, like those with romantic partners, and some are involuntary, like those with siblings. Likewise, some social relationships are voluntary, like those with acquaintances, and some are involuntary, like those with neighbors or distant relatives. You can see how various relationships fall into each of these dimensions in Figure 1 “Types of Relationships”. Now that we have a better understanding of how we define relationships, we’ll examine the stages that most of our relationships go through as they move from formation to termination.
Stages of Relational Interaction
Communication is at the heart of forming our interpersonal relationships. It is through our communication that we adapt to the dynamic nature of our relational worlds, given that relational partners do not enter each encounter or relationship with compatible expectations. Communication allows us to test and be tested by our potential and current relational partners. It is also through communication that we respond when someone violates or fails to meet those expectations (Knapp & Vangelisti, 2009).
There are ten established stages of interaction that can help us understand how relationships come together and come apart (Knapp & Vangelisti, 2009). We will discuss each stage in more detail, but in Table 7.1 “Relationship Stages” you will find a list of the communication stages. We should keep the following things in mind about this model of relationship development: relational partners do not always go through the stages sequentially, some relationships do not experience all the stages, we do not always consciously move between stages, and coming together and coming apart are not inherently good or bad. As we have already discussed, relationships are always changing—they are dynamic. Although this model has been applied most often to romantic relationships, most relationships follow a similar pattern that may be adapted to a particular context.

Initiating
In the initiating stage, people size each other up and try to present themselves favorably. Whether you run into someone in the hallway at school or in the produce section at the grocery store, you scan the person and consider any previous knowledge you have of them, expectations for the situation, and so on. Initiating is influenced by several factors.
If you encounter a stranger, you may say, “Hi, my name’s Rachel.” If you encounter a person you already know, you’ve already gone through this before, so you may just say, “What’s up?” Time constraints also affect initiation. A quick passing calls for a quick hello, while a scheduled meeting may entail a more formal start. If you already know the person, the length of time that’s passed since your last encounter will affect your initiation. For example, if you see a friend from high school while home for winter break, you may set aside a long block of time to catch up; however, if you see someone at work that you just spoke to ten minutes earlier, you may skip initiating communication. The setting also affects how we initiate conversations, as we communicate differently at a crowded bar than we do on an airplane. Even with all this variation, people typically follow typical social scripts for interaction at this stage.
Experimenting
The experimenting stage of a relationship is like a first test run—people exchange basic info to move from strangers to acquaintances. It’s similar to animals sniffing each other out: casual chats about where you’re from, your major, or shared interests like sports. If the conversation flows, it might lead to a connection. If it stalls or feels awkward, it’s often a sign not to pursue it further.
This stage doesn’t just happen with new people—it continues in ongoing relationships, too. Small talk is a big part of it, whether it’s catching up with your parents during a visit or chatting with a partner while cooking dinner. Even though it can feel forced or superficial (like when someone talks to you at the gym even though you have earbuds in), small talk has value. It helps break the ice, tests compatibility, and builds a sense of connection. Interestingly, research shows that many of our relationships never move beyond this stage—and that’s okay.
Intensifying
As we enter the intensifying stage, we indicate that we would like or are open to more intimacy, and then we wait for a signal of acceptance before we attempt more intimacy. This incremental intensification of intimacy can occur over a period of weeks, months, or years and may involve inviting a new friend to join you at a party, then to your place for dinner, then to go on vacation with you. In the intensifying stage, relationships grow closer through small, gradual steps—like hanging out more, sharing personal info, or doing favors for each other. People may use nicknames, inside jokes, or say “we” instead of “I,” showing a deeper connection. Sharing space or belongings can also signal growing trust. But if things move too fast or feel one-sided, the relationship can become strained. Navigating this stage carefully can lead to a stronger, more integrated bond.
Integrating
In the integrating stage, two people’s identities and personalities merge, and a sense of interdependence develops. Even though this stage is most evident in romantic relationships, there are elements that appear in other relationship forms. Some verbal and nonverbal signals of the integrating stage are when the social networks of two people merge; those outside the relationship begin to refer to or treat the relational partners as if they were one person (e.g., always referring to them together—“Let’s invite Olaf and Bettina”); or the relational partners present themselves as one unit (e.g., both signing and sending one holiday card or opening a joint bank account). Even as two people integrate, they likely maintain some sense of self by spending time with friends and family separately, which helps balance their needs for independence and connection.
Bonding
The bonding stage includes a public ritual that announces formal commitment. These types of rituals include weddings, commitment ceremonies, and civil unions. Obviously, this stage is almost exclusively applicable to romantic couples. In some ways, the bonding ritual is arbitrary, in that it can occur at any stage in a relationship. In fact, bonding rituals are often later annulled or reversed because a relationship doesn’t work out, perhaps because there wasn’t sufficient time spent in the experimenting or integrating phases. However, bonding warrants its own stage because the symbolic act of bonding can have very real effects on how two people communicate about and perceive their relationship. For example, the formality of the bond may lead the couple and those in their social network to more diligently maintain the relationship if conflict or stress threatens it.

Differentiating
Individual differences can present a challenge at any given stage in the relational interaction model; however, in the differentiating stage, communicating these differences becomes a primary focus. Differentiating is the reverse of integrating, as we and our reverts back to I and my. People may try to reset boundaries in their life prior to the integrating of the current relationship, including other relationships or possessions. For example, Carrie may reclaim friends who became “shared” as she got closer to her roommate Julie and their social networks merged by saying, “I’m having my friends over to the apartment and would like to have privacy for the evening.” Differentiating may onset in a relationship that bonded before the individuals knew each other in enough depth and breadth. Even in relationships where the bonding stage is less likely to be experienced, such as a friendship, unpleasant discoveries about the other person’s past, personality, or values during the integrating or experimenting stage could lead a person to begin differentiating.
Circumscribing
To circumscribe means to draw a line around something or put a boundary around it (Oxford English Dictionary Online, 2011). So in the circumscribing stage, communication decreases and certain areas or subjects become restricted as individuals verbally close themselves off from each other. They may say things like “I don’t want to talk about that anymore” or “You mind your business and I’ll mind mine.” If one person was more interested in differentiating in the previous stage, or the desire to end the relationship is one-sided, verbal expressions of commitment may go unechoed—for example, when one person’s statement, “I know we’ve had some problems lately, but I still like being with you,” is met with silence. Passive-aggressive behavior and the demand-withdrawal conflict pattern, which we discussed in Chapter 6 may occur more frequently in this stage. If there is an increase in boundaries and a decrease in communication becomes a pattern, the relationship further deteriorates toward stagnation.
Stagnating
During the stagnating stage, the relationship may come to a standstill, as individuals basically wait for the relationship to end. Outward communication may be avoided, but internal communication may be frequent. The relational conflict flaw of mindreading takes place as a person’s internal thoughts lead them to avoid communication. For example, a person may think, “There’s no need to bring this up again, because I know exactly how he’ll react!” This stage can be prolonged in some relationships. Parents and children who are estranged, couples who are separated and awaiting a divorce, or friends who want to end a relationship but don’t know how to do it may have extended periods of stagnation. Short periods of stagnation may occur right after a failed exchange in the experimental stage, where you may be in a situation that’s not easy to get out of, but the person is still there.
Avoiding
Moving to the avoiding stage may be a way to end the awkwardness that comes with stagnation, as people signal that they want to close down the lines of communication. Communication in the avoiding stage can be very direct—“I don’t want to talk to you anymore”—or more indirect—“I have to meet someone in a little while, so I can’t talk long.” While physical avoidance such as leaving a room or requesting a schedule change at work may help clearly communicate the desire to terminate the relationship, we don’t always have that option. In a parent-child relationship, where the child is still dependent on the parent, or in a roommate situation, where a lease agreement prevents leaving, people may engage in cognitive dissociation, which means they mentally shut down and ignore the other person even though they are still physically present.
Terminating
The terminating stage can happen early or after many years together. It may be caused by distance, growing apart, or changes in values. Breakups often include a summary of the relationship, an explanation for ending it, and a message about growing apart. People may also talk about what comes next and whether they’ll stay in touch. These kinds of conversations reflect how relationships evolve and how people decide whether the connection is still worth the effort.
Social Exchange Theory

Figure 7.1.3 Cost-Rewards Scale
Social exchange theory essentially entails a weighing of the costs and rewards in a given relationship (Harvey & Wenzel, 2006). Rewards are outcomes that we get from a relationship that benefit us in some way, while costs range from granting favors to providing emotional support. When we do not receive the outcomes or rewards that we think we deserve, then we may negatively evaluate the relationship, or at least a given exchange or moment in the relationship, and view ourselves as being underbenefited. In an equitable relationship, costs and rewards are balanced, which usually leads to a positive evaluation of the relationship and satisfaction.
Commitment and interdependence are important interpersonal and psychological dimensions of a relationship that relate to social exchange theory. Interdependence refers to the relationship between a person’s well-being and involvement in a particular relationship. A person will feel interdependence in a relationship when (1) satisfaction is high or the relationship meets important needs; (2) the alternatives are not good, meaning the person’s needs couldn’t be met without the relationship; or (3) investment in the relationship is high, meaning that resources might decrease or be lost without the relationship (Harvey & Wenzel, 2006).
We can be cautioned, though, to not view social exchange theory as a tit-for-tat accounting of costs and rewards (Noller, 2006). We wouldn’t be very good relational partners if we carried around a little notepad, notating each favor or good deed we completed so we can expect its repayment. As noted earlier, we all become aware of the balance of costs and rewards at some point in our relationships, but that awareness isn’t persistent. We also have communal relationships, in which members engage in a relationship for mutual benefit and do not expect returns on investments such as favors or good deeds (Harvey & Wenzel, 2006). As the dynamics in a relationship change, we may engage communally without even being aware of it, just by simply enjoying the relationship. It has been suggested that we become more aware of the costs and rewards balance when a relationship is going through conflict (Noller, 2006). Overall, relationships are more likely to succeed when there is satisfaction and commitment, meaning that we are pleased in a relationship intrinsically or by the rewards we receive.
