Social penetration theory
The social penetration theory proposes that, as relationships develop, interpersonal communication moves from relatively shallow, non-intimate levels to deeper, more intimate ones. The theory was formulated by psychologists Irwin Altman and Dalmas Taylor in 1973 to provide an understanding of the closeness between two individuals.
The social penetration theory states that this process occurs primarily through self-disclosure and closeness develops if the participants proceed in a gradual and orderly fashion from superficial to intimate levels of exchange as a function of both immediate and forecast outcomes. Altman and Taylor believe that only through opening one's self to the main route to social penetration-self-disclosure-by becoming vulnerable to another person can a close relationship develop. Vulnerability can be expressed in a variety of ways, including the giving of anything which is considered to be a personal possession, such as a dresser drawer given to a partner. This psychological theory, as with many others, is applied in the context of interpersonal communication. It can also be defined as the process of developing deeper intimacy with another person through mutual self-disclosure and other forms of vulnerability. The Social Penetration theory is known as an objective theory, meaning that the theory is based on data drawn from experiments, and not from conclusions based on individuals' specific experiences. This theory is also guided by the assumptions that relationship development is systematic and predictable and also includes deterioration, or growing apart, besides the major four stages.
As for the speed of self-disclosure, Altman and Taylor were convinced that the process of social penetration moves a lot faster in the beginning stages of a relationship but then it slows considerably. Those who are able to develop a long term, positive reward/ cost outcome are the same people who are able to share important matches of breadth categories. The early reward/ cost assessment have a strong impact on the relationships reactions and involvement. When you have expectancies in a relationship regarding the future it plays a major role on the outcome in the relationship.
To self-disclose, one must open up their inner feelings, this could be anything from their personal motives or desires. To self disclose could bring a relationship to a new level of intimacy.

Social penetration is perhaps best known for its onion analogy, therefore it is sometimes called the “onion theory” of personality. Personality is like a multi-layered onion with public self on the outer layer and private self at the core. As time passes and intimacy grows, the layers of one's personality begin to unfold to reveal the core of the person. Three major factors influence self-revelation and begin the process of the onion theory, which are personal characteristics, reward/cost assessments, and the situational context.
- Orientation stage. In this first stage we engage in small talk and simple, harmless clichés like, ‘Life’s like that’. This first stage follows the standards of social desirability and norms of appropriateness.
- Exploratory affective stage. We now start to reveal ourselves, expressing personal attitudes about moderate topics such as government and education. This may not be the whole truth as we are not yet comfortable to lay ourselves bare. We are still feeling our way forward. This is the stage of casual friendship, and many relationships do not go past this stage.
- Affective stage. Now we start to talk about private and personal matters. We may use personal idioms. Criticism and arguments may arise. There may be intimate touching and kissing at this stage.
- Stable stage. The relationship now reaches a plateau in which some of the deepest personal thoughts, beliefs, and values are shared and each can predict the emotional reactions of the other person.
- Depenetration stage (optional). When the relationship starts to break down and costs exceed benefits, then there is a withdrawal of disclosure which leads to termination of the relationship.
Breadth and depth
Both depth and breadth are related to the Onion Model. As the wedge penetrates the layers of the onion, the degree of intimacy (depth) and the range of areas in an individual’s life that an individual chooses to share (breadth) increases.
Breadth of penetration refers to the different segments of a person’s life. For instance one segment can be family while another could be a romantic relationship or even academic studies could be thought of as another type of segment. Each of these segments or areas is not always accessed at the same time. One could be completely open about a family relationship while hiding an aspect of a romantic relationship for various reasons such as abuse or disapproval from family or friends. It takes genuine intimacy with all segments to be able to access all areas of breadth at all times.
Depth is defined as: The degree in which someone is intimate with someone else. This does not necessarily refer to sexual activity, but more to the idea of how open and close someone can become with another person despite their anxiety over self-disclosure. Doing this will give the person more trust in the relationship and make them want to talk to you about deeper things than what is on the surface of a normal everyday conversation.This could be through friendship, family relationships, peers, and even romantic relationships with either same-sex or opposite-sex relationships.
How do you move to deeper intimacy levels? When talking with the person over time make more topics to talk about so they will start to open up to you and express different things towards the topics and what they feel towards different issues. This helps you to move closer to getting to know the person and how they react to different things. Getting to know the person will show their true colors. From attitudes, family, and romantic relationship status, many things can come from this after getting in depth with a person to know their background and how they were brought up.
There are four thoughts within the process of depth of penetration (Arun Jacob,2009). These are known as:
- “Peripheral items are exchanged more frequently and sooner than private information.”
- “Self-disclosure is reciprocal, especially in the early stages of relationship development.”
- “Penetration is rapid at the start but slows down quickly as the tightly wrapped inner layers are reached.”
- “Depenetration is a gradual process of layer-by-layer withdrawal.”
It is possible to have depth without breadth and even breadth without depth. For instance, depth without breadth could be where only one area of intimacy is accessed. “A relationship that could be depicted from the onion model would be a summer romance. This would be depth without breadth.” On the other hand, breadth without depth would be simple everyday conversations. An example would be when passing by an acquaintance and saying, “Hi, how are you?” without ever really expecting to stop and listen to what this person has to say is an everyday instance.
To get to the level of breadth and depth you have to work your way down and work on your social skills and how you present yourself to people. You have to be willing to open up and talk to the person and express yourself to them. Let a little bit of your personal life out and see how they respond to it. If they want to talk about it they will talk about it. If they do not want to open up the first time you have to keep talking to them and have many conversations to where they feel comfortable enough for them to want to talk to you about personal things in their life.
Rewards and costs assessment
Social penetration theory states that humans, even without thinking about it, weigh each relationship and interaction with another human on a reward cost scale. If the interaction was satisfactory, then that person or relationship is looked upon favorably. But if an interaction was unsatisfactory, then the relationship will be evaluated for its costs compared to its rewards or benefits. People try to predict the outcome of an interaction before it takes place. Coming from a scientific standpoint, Altman and Taylor were able to assign letters as mathematical representations of costs and rewards. They also borrowed the concepts from Thibaut and Kelley's [] in order to describe the relation of costs and rewards of relationships. Thibaut and Kelley's key concepts of relational outcome, relational satisfaction, and relational stability serve as the foundation of Irwin and Taylor's rewards minus costs, comparison level, and comparison level of alternatives.
A major factor of disclosure is an individual calculation in direct relation to benefits of the relationship at hand. Each calculation is unique in its own way because every person prefers different things and therefore will give different responses to different questions.
The more you disclose to your partner the greater intimacy reward you will receive. When the individuals who are involved in the relationship hold positive values in this calculation intimacy proceeds at an accelerated rate. In the relationship if you and your partner are dyad the cost exceeds the rewards. The relationship then will slow considerably, and future intimacy is less likely to happen.
This means that people want to maximize their rewards and minimize their costs when they are in a relationship with somebody. According to Altman and Taylor, relationships are sustained when they are relatively rewarding when the outcome is positive and discontinued when they are relatively costly (when the outcome is negative).
- Outcome = Rewards – Costs
The first standard that we use to evaluate the outcomes of a situation is comparison level. As defined by Thibaut and Kelley, comparison level is the standard by which individuals evaluate the desirability of group membership. A group is defined as “two or more interdependent individuals who influence one another through social interaction." In this instance, the group refers to a dyadic relationship, but it can really be extended to any type of group. "A person's comparison level (CL) is the threshold above which an outcome seems attractive". That is, when groups fall above the CL they are seen as being satisfying to the individual, and when they fall below the CL they are seen as being unsatisfying. We take an average of outcomes from the past as a benchmark to determine what makes us happy or sad so that we may develop the threshold, or comparison level, in which an outcome appears attractive. Our past experiences really do shape our thoughts and feelings about developing relationships with people, and in this way, an individual’s CL is very much influenced by these previous relationships.
Comparison level of alternatives
Comparison level only predicts when we are satisfied with membership in a given relationship, or group. Therefore, Thibaut and Kelley also say that people use a comparison level for alternatives to evaluate their outcomes. Basically, CLalt is determined by "the worst outcome a person will accept and still stay in a relationship." As such, comparison level for alternatives is a better predictor for whether or not a person will join or leave a relationship, or group. However, even if a relationship is unhealthy a person might choose to remain in it because it is better than what they perceive the real world to be.
Extensive research and applications
Without doubt, the value of Social Penetration Theory initially lie into the area of interpersonal communication. Scholars have been using the concepts and onion model to explore the development of counter-sex/romantic relationships, friendships, parent-child relationships, employer-employee relationships, and caregiver-patient relationships and beyond. Some of the key findings are described as follows.
Researchers have found out that in parent-child relationship, information derived from the child's spontaneous disclosure in daily life activities was most closely connected to generating and maintaining his/hers trust in parents, indicating the importance of developing shallow but broad relationship with children like everyday conversation but not long-lasting profound lectures (Kerr, Stattin & Trost, 1999). Scholars also use this theory to examine other factors influencing the social penetration process in close friendship. As Mitchell and William (1987) put it, ethnicity and sex do have impact on the friendship foster. The survey results indicates that more breadth of topics occurs in penetration process in black friendship than white. Regarding the caregiver-patient relationship, developing a social penetrated relationship with institution disclosed breadth and depth information and multiple effective penetration strategies is critical to the benefits of the patients(Yin & Lau, 2005). Nurses could apply the theory into the daily interactions with patients, so as the doctors ' articulations when consulting or announcing.
In addition, the relationship between nonverbal behavior and social penetration process has been a hot topic. An interesting study conducted among university drama student actresses discovers that casual acquaintances discussing intimate topics tend to use more intensive nonverbal behaviors than the good friends do (Keiser & Altman, 1976).
The ideas posits by the theory have been researched, re-examined by scholars when look at organizational communication. Some scholars explored the arena of company policy making, demonstrating that the effect which company policies posing on the employees ranges from slight attitudinal responses (such as dissatisfaction) to radical behavioral reactions (such as conflicts, fight and resignation). In this way, sophisticated implementation of the controversial policies is highly required (Baack, 1991). Social penetration theory offers a framework which allows for explanation of the potential issues.
Computer-mediated communication (CMC) can be thought of as another way in which people can develop relationships. Internet has thought to broaden the way people communicate and build relationships. By opening up a new window in which people could be open-minded and unconventional and partners from traditional limitations like time and place. (Yum & Hara, 2005)
Some theorists find this concept impossible and there are barriers to this idea. Since there are risks and there is usually more uncertainty about whether the person on the other side of the computer is being real and truthful, or deceitful and manipulative for one reason or another there is no possible way to build a relationship. A lack of face-to-face can cause heightened skepticism and doubt. Since this is possible, there is no chance to make a long lasting and profound connection.
Self-disclosure has been studied when it comes to face-to-face interactions. Since the ideas of social networking sites are new phenomena there are not as many studies done about how people disclose information over a computer compared to a one-on-one interaction. There are still a couple surveys done about how social networking sites such as Facebook, MySpace, Twitter, LinkedIn, hi5, myyearbook, or Friendster affect interactions between human beings. Take Facebook as an example, users are able to determine their level and degree of self-disclosure by setting their privacy settings (McCarthy, 2009). People achieve the breadth via demonstrating everyday life and share surface information while develop intimate relationship with great depth by sending private Facebook messages and creating closed group.
There was a study done about the connection on how couples or other romantic relationships have trust, commitment, and affection towards each other and the amount of self-disclosure each person gives to the one another. There are several criteria to the study. One important is how the couple met. If they met before talking over the Internet they are more likely to reveal personal information due to trusting someone easier. According to Rempel, Holmes, & Zanna (1985) the best way to be able to trust someone is to be able to foretell or calculate how another person will act or react to any given information. In other words, we are more probable to release information about ourselves if we can expect the behavior of the other person.
“The hyperpersonal perspective suggests that the limited cues in CMC are likely to result in over attribution and exaggerated or idealized perceptions of others and that those who meet and interact via CMC use such limited cues to engage in optimized or selective self-presentation”. (Walther, 1996) What this author means is there could be deceitful or dishonest intents involved from people on the Internet. There are possibilities that someone could mislead another person because there are more opportunities to build a bigger and better identity without much worry for persecution. If there is no chance of ever meeting the person on the other end of the computer, then there is a high risk of falsifying information and credentials.
Other theorists such as Rubin and Bargh say that because of the blockade of the computer, it increases how likely people are to be true and honest about themselves. There is also the idea that there will not be any fear of consequences for less than respectable decisions made in the past. Computer mediated communication has also been thought to even speed up the intimacy process because computers facilitate individual communication to be more, rather than fewer, open and accommodating about characteristics of the person or persons involved. Both idea and types of theories can be proved and disproven but it all depends on how an individual uses and or abuses computer mediated communication.
As for sexual relationships, some scholar posits that when initiating a romantic relationship, there are important differences between internet dating site and other spaces, such as the depth and breadth of the self-disclosed information taken place before they go further to one-on-one conversation(Monica, 2007). Other study has shown that in real life adolescent tend to engage in sexual disclosure according to the level of relationship intimacy, which supports the social penetration model; but in cyberspace, men present a stronger willingness and interests to communicate without regarding the current intimacy status or degree (Yang, Yang & Chiou, 2010). There are also many counter-examples of the theory existed in romantic relationships development. To date, it's no surprise that some adolescents talked about the most intimate stuff when they first met online or had sex without knowing each other thoroughly. Contrary to the path stated by social penetration theory, the relationship developed from the core with the highest depth to the superficial surface of large breadth. In this way, sexual disclosure on the part of adolescents under certain circumstances departs from the perspective of the social penetration theory.
Blogging and online chatting
With the advent of Internet, blogs and online chatting have sprung up all over the globe. Then what changes have been taken place during the interpersonal communication process? According to Jih-Hsin Tang, Cheng-Chung Wang, bloggers tend to have significantly different patterns of self-disclosure for different target audiences. The online survey which involved 1027 Taiwanese bloggers examined the depth and breath of what bloggers disclosed to the online audience, best friend and parents as well as nine topics they revealed. Regarding online chat, research conducted by Dietz Uhle, Bishop Clark and Howard shows that "once a norm of self-disclosure forms, it is reinforced by statements supportive of self-disclosures but not of non-self disclosures." 
- The scope of the theory is limited 
- Theory not fully supported by data
- Highest reciprocity may occur at middle levels; may be cycles of disclosure and reserve
- Needs take account of gender (males less open)
- Disclosure can increase as relationship deteriorates
- Single comparison (CL) index too simplistic
- In close relationships, self-centeredness lessens
- Onion metaphor: sexual; disclosure is active, usually symmetrical; self is not simply revealed but is constructed
- The original theory did not account for gender differences in vulnerability, but later research concludes that males are less open than females.
