Social Penetration Theory Psychology

Abstract
The Social Penetration Theory is a communication and psychology theory first written by Irwin Altman and Dalmas Taylor. The theory outlines concepts of social interaction that takes place when two people are getting to know each other. Altman and Taylor proposed that closeness occurs between two people through a gradual process of self-disclosure. The theory relies heavily on the ‘Onion’ analogy that suggests that people are like multi-layered onions and have different layers of their personality that they may or may not reveal over time depending on the interaction that takes place. The theory also outlines other aspects of social interaction such as the ‘cost and reward’ concept. This concept suggests that people base their relationships around the cost and reward outcomes and how they can benefit from that relationship.
This report explains in detail the key concepts and ideas of the Social Penetration theory as well as other theories that are related with social penetration such as the Social Exchange Theory. To further investigate the effects of Social Penetration experimental research was found to support the effects of self-disclosure in regards to the Social Penetration Theory.
After comprehensive study and research on this topic it was found that closeness between two people develops over a period time and through a process of self-disclosure. If self-disclosure is not apparent then the relationship is likely to fail. According to the theory people base their friendships on a process of cost and reward benefits but will usually do this sub-concisely without knowing that they have used this method to determine their relationships. Key ideas such as ‘comparison levels’ suggest that an individual determines whether the relationship is working by the process of profits = Rewards – Costs.
Introduction
Purpose
The purpose of this report is to understand the social interaction that takes place between people and to study the fundamentals of human behaviour during the gradual process of social penetration. This report is aimed at giving the reader a better understanding of key concepts of the Social Penetration theory and how it is used in everyday situations.
Scope
To fully understand and explain this theory research was conducted over several areas that directly relate to the Social Penetration Theory. These areas of research came from 6 main literature sources ranging from journal articles to large-scale social experiments that put the theory into practice. Internet research was also conducted.
Limitations
The limitations of this report include:
Availability of information
Due to the detail needed to fully understand the concepts of this theory commonly used sources such as libraries proved to be of little help when finding information to write this report. Detailed Internet sites were also hard to come by when researching this theory.
Time restrictions:
At first time was not considered to be a major issue but due to the availability of information in both library sources and databases time restrictions did become a concern nearing the deadline of this report.
Research methods
When conducting research regarding the Social Penetration Theory commonly used sources such as libraries were not as useful as they normally would be. Although two of the 6 sources were gathered from libraries other information that was found in books was concentrated into sections of no more than 5 pages. Because this report needed to be detailed and informative these sources were of no use. When detailed books were finally found they were still not as useful as the longer articles found using Internet sites and databases. When searching for information using Internet databases such as Proquest I was able to find much more in-depth and detailed information into the study of Social Penetration. Searching for information using Internet articles and journals proved to be the best way to find accurate sources.

Summary
The information in this journal was produced by doing an experiment regarding self-disclosure and the Social Penetration process. It also explains in detail the key concepts of social interaction and self-disclosure. The author examined whether the level of self disclosure would differ across four types of relationships: passionate love relationships, companion love relationships, same-sex friendships and cross-sex friendships. The experiment was done by American and Japanese participants to examine any cultural differences in self-disclosure. The results produced three main hypotheses, Japanese students scored lower than American students in self disclosure regardless of relationship type, Self disclosure was higher in same sex friendships than in cross sex friendships in both American and Japanese students and self disclosure was higher in romantic relationships than in friendships among both American and Japanese students (Kito, M. 2002). The article also has information regarding each relationship type and previous authors that have studied similar topics and experiments.

Summary
This internet article has a brief summary that identifies the main concepts of the social penetration theory. The article also has a section on scientific assumptions which tries to explain that social penetration can be referred to as a scientific theory. It argues this point by saying that if self disclosure is high then the relationship will develop; this statement can be seen as an equation and therefore can be viewed as a scientific. Critique is another scientific concept that is explained in this article. This refers to predictions that are made on the relationship development based on the levels of self-disclosure within the relationship. The article also explains in detail how Altman and Taylor’s Onion analogy operates and how the theory compares people to multilayered onions. The ideas behind breadth and depth are also explained in this article.

Irwin Altman is currently a professor at the University of Utah in Salt Lake City teaching psychology and social communication.
Dalmas Taylor
Dalmas Taylor was born in 1934 in Detroit, Michigan. After showing an interest in psychology in his teenage years he later went on to study for his Bachelor of Arts degree in Psychology from Western Reserve University in Cleveland, Ohio. His research and interest in psychology eventually lead him to further his studies when he received his Masters degree in psychology from Howard University in Washington D.C and his Ph.D. in psychology from the University of Delaware. Taylor also gained a certificate from Harvard University Business School. Early in his career Taylor worked with the SPSSI (Society for the Psychological Study of Social Issues). During the late 1960s Taylor was the chairman of the Dissertation Award Committee and served for the SPSSI council for several years. During the 1970s Taylor began to teach psychology at various universities throughout North America and eventually became a Professor at the University of Maryland where he taught for 16 years.
Taylor also worked with the APA (American Psychological Association) and eventually became a member of groups such as the Board of Ethic Minority Affairs, the Committee on Employment and Human Resources, the Policy and Planning Board and the Committee on Ethics Code Revision. His work with the American Psychological Association made very well known among psychologists and he received numerous awards from the APA. Later in his courier Taylor received the Distinguished Contribution to Education and Training Award of the Association and in 1992 he received the Distinguished Service Award for Outstanding Contributions to Psychology in the Public Interest. In final stages of his career Taylor served as Vice President of Academic Affairs at Lincoln University in Pennsylvania. Dalmas Taylor died in January 1998 at the age of 64 due to medical conditions.
Outline Of Theory/key Issues
Psychologists Irwin Altman and Dalmas Taylor first established the Social Penetration Theory in 1973. The theories main objective was to explain how relation closeness develops over time. Altman and Taylor suggested that closeness develops within a relationship through a gradual process of self-disclosure, they believed that this process could occur both consciously and sub-consciously when any kind of relationship is developing.
This section of the report will describe the Social Penetration Theory by explaining its key concepts including:

The onion analogy
Self-disclosure
Cost and reward outcomes/ Social Exchange Theory
Depenetration and withdrawal

The Onion Analogy
The Onion analogy can be seen as the most notable aspect of the Social Penetration Theory. The model literally depicts an onion and is used as an analogy by Altman and Taylor to explain the foundations of social penetration. The analogy states that humans consist of layers much like an onion. Each layer reveals more about an individual’s personality, the outer layers contain less personal information and the deeper layers consists of the most private details of a person’s character. As a result the more layers penetrated the harder it becomes to ‘unlock’ the next layer. Often the type of relationship will have a heavy impact on the degree of penetration that occurs for example family relationships, personal relationships, same sex friendships and opposite sex friendships may all have different degrees of penetration that take place during a relationship.
The penetration of the layers can be associated with two concepts. The first is ‘breadth’ which refers to the amount of issues and variety of topics being discussed and the second is ‘depth’ which refers to the degree of intimacy being applied on each topic. Each layer has a level of ‘breath’ and ‘depth’ depending on how personal the relationship has become for example friendships may have different levels of ‘breadth’ and ‘depth’ compared to a more personal relationship with a partner.
Surface Layers
The surface layers can be seen as superficial information about an individual such as what they look like, how they dress, their body language and how they talk. Information on the outer layers is given out a lot faster than the inner layers because it is not as personal. The surface layers can often be altered so that an individual can change the appearance they are producing when entering a social situation often for the first time. These changes will usually be things like the way they look and dress or material items such as cars or jewelry. The surface layers help to create a first impression to the outside world and is readily available to anyone who wishes to notice. After the initial surface layer is penetrated information such as their likes and dislikes, favorite movies, musical preferences etc. are revealed as the relationship progresses through the beginning stages.
Central Layers
The central or middle layers of the Onion Model can be seen as the characteristics of an individual’s personality. This includes aspects such as religious beliefs, personal values and what they consider to be right from wrong. The central layers hold more understanding into a person’s upbringing and culture. The central layers are usually only penetrable by people who know that individual well. In most cases it is unlikely that common friendship will go beyond the central layers.
Inner Layers
The inner layer of the Onion model holds a person’s most intimate secrets and beliefs. It is the foundation of their personality and their self-concept. This layer can only be penetrated by the people who are closest to individual such as family members or their partner. Even then a person’s most inner secrets might only be accessible by the individual them self. The inner layers of the Onion Analogy will heavily influence the central and surface layers because it is the basis of their personality.
Self-Disclosure
The term self-disclosure refers to the act of revealing details about oneself to others. This process can happen both consciously and sub-consciously depending on the degree of intimacy at any given point throughout the relationship. Personal and intimate details about our personality are usually revealed over time as the relationship becomes more meaningful and important to us.
Altman and Taylor believed that the only way a relationship can develop is through a gradual process of self-disclosure. This process is necessary in both romantic relationships and friendships. The act of self-disclosure is one of the main principals in the study of social penetration as well as psychology. Altman and Taylor state that this is the key process that decides if a relationship will succeed or fail particularly if it is a romantic relationship. Altman and Taylor’s ideas on self-disclosure have sparked many studies on the effects of self-disclosure in both close relationships and common friendships. In 1986 Berg and McQuinn tested self-disclosure by asking couples that had recently started dating to complete a self-disclosure examination. Four months later the couples were then asked to take the same examination. It was found that couples that were still together four months later reported greater self-disclosure at the initial contact then those who had later broken up. This experiment suggested that the level self-disclosure was not only based on the length of the relationship but also the satisfaction levels of the individuals when they were first getting to know each other (Berg & McQuinn.1986). Altman and Taylor believed that the process of self-disclosure allowed for a relationship to develop to a more personal level. By allowing this process to occur penetration can take place through the various layers of the ‘onion’ (the onion analogy). Altman and Taylor believed that the process of penetrating the inner onion layers is especially important when long-term relationships are developing thus making the process of self-disclosure one of the key concepts of the Social Penetration Theory.
Cost And Reward Outcomes/Social Exchange Theory
The cost and reward outcomes of the Social Penetration Theory were initially based around the concepts developed from Social Exchange Theory. Psychologists John Thibaut and Harold Kelly were seen as the main developers of the Social Exchange Theory in 1959. The Theory is based on a model of cost and reward outcomes of relationships (both friendships and personal relationships) and states that people develop relationships based on whether or not they will profit in the long run. Thibault and Kelly claim that based on the equation: profits = Rewards – Costs, people will continue being in a relationship if the profit or outcome is in their favour.
The idea of costs and rewards is analysed in the theory by using the concept of ‘Comparison levels’. This concept suggests that people have a general idea of what they expect or what they deserve to get out of any particular relationship whether it’s a personal relationship or friendship, this is your known as your ‘comparison level’. For example in a personal long-term relationship the individual might expect high levels of trust, love and commitment. If the relationship has just started however they may expect lower levels of privacy, sexual activity and deep communication. When the rewards and profits out way this comparison level the satisfactory level of the relationship will increase for that particular individual.
‘Comparison levels for alternatives ‘refers to the suggestion that people will compare the rewards they are getting out of their current relationship with rewards and profits they could get out of an alternative relationship. For example an individual may feel that they are getting the maximum profits out of their current relationship therefore they are likely to stay with their current partner. If however they feel the relationship has more costs than rewards they are likely to leave that relationship to find a more profitable relationship (DeVito, J. 2004). Altman and Taylor’s Social Penetration Theory relies on this same method of cost and reward outcomes to determine the path of a relationship.
Depenetration And Withdrawal
Although the Social Penetration Theory examines how a relationship develops it also acknowledges and describes the ways in which depenetration and withdrawal can occur. This occurs when the relationship begins to deteriorate either because of a falling out or simply because the individuals begin to grow apart. The first stage of deterioration is usually ‘intrapersonal dissatisfaction’, this occurs when everyday life with the individual seems to be less and less eventful or for filling. If this dissatisfaction continues then the relationship will proceed to the next stage of deterioration. This stage is known as ‘Interpersonal deterioration’, this stage involves growing further and further apart and spending less free time with that individual then they would have at previous points in the relationship. The process of withdrawal or depenetration occurs when one or more of the individuals begin to close of areas of their lives that had once been open in the earlier stages of the relationship. As a result the ‘breadth’ and ‘depth’ which once made the relationship more intimate and personal will now begin to reverse. This process can be seen as taking back what has already been used to build the foundations of the relationship, if the foundations are no longer apparent then the relationship becomes unstable. Altman and Taylor have compared this stage of depenetration to watching a movie in reverse (Griffin,EM 2006), in other words everything that has been put into the relationship will now begin to be withdrawn to some extent. A decline in self-disclosure will also be apparent because of the fact there is now less communication and social activities taking place. If there is a decline in self-disclosure levels then the relationship will no longer move forward. The absence of self-disclosure can often be due to a number of contributing factors including; one or more of the individuals no longer feeling comfortable to communicate with the other on a personal level, they are no longer trust worthy or they are simply not worth the effort. The depenetration and deterioration of a relationship rarely ends in a sudden burst of realisation but rather a gradual process of withdrawal due to lack of enjoyment and intimacy levels in the relationship.
Application Of Theory
The process of social penetration is solely based on communication and social interaction. As a result this theory is put into practice every day in a variety of situations from common greetings to a work mate to a personal conversation with a family member. Different social interactions will involve different levels of self-disclosure and communication. To illustrate how the theory affects people in everyday life an experiment was found to describe the effects of social penetration and self-disclosure in common relationships including friendships and romantic relationships.
This experiment was done by Mie Kito from the California State University as part of her undergraduate honors program in 2003. The experiment gained her an award for research and creativity and was presented at the 83rd annual Western physiological Association Convention in Vancouver in May 2003. The purpose of the experiment was to examine different levels of self-disclosure among American and Japanese college students. She examined students that were involved in romantic relationships, companionate relationships and same sex and opposite sex friendships to find out if both cultural background and relationship types played a major role in the level of self-disclosure that was applied in everyday situations. To gain an accurate sample she found a selection of 145 college students, 64 of the students were American and 81 were Japanese. The purpose and aim of the survey was not disclosed to the participants and the information they provided was confidential and no names were obtained to ensure the participants remained anonymous.
The methods and procedures she used where as follows:

Three standardized methods were used within the survey gain an accurate sample. These methods were the self-disclosure index (Miller. Berg. & Archer.1983), the Passionate love scale (Hatfield & Spencer. 1986) and the companionate love scale (Hatfield. 1986). The self-disclosure index is a target specific tool that can be used to measure self-disclosure among certain groups. The main differences between the companionate love scale and the passionate love scale is that passionate love refers to the feeling of unity with another individual who is not currently present where as companionate love refers to the bond between someone who is already heavily involved within an individual’s life. When answering questions about passionate relationships the participants were asked to think of their current partner, if they did not currently have a partner then they were asked to think of the last partner that they shared deep feelings for. If the questions involved any friendships they were then asked to think of their closest friendship with either a same sex friend or opposite sex friend depending on the required relationship type for that question.
The self-disclosure index included 10 questions of personal information including personal habits, things that the participant wouldn’t do in public and their personal feelings on certain issues. Each relationship type was modified to relate to the available answers that could be chosen by the participant. For example one of the questions for the self-disclosure index for a Passionate love relationship was, “I am willing to talk about my deepest feelings on a personal issue with the person I am romantically involved with” and another question for self-disclosure in a same sex friendship was “I’m willing to talk about my deepest feelings on a personal issue with a same sex friend”, She then provided the participants with scale of answers to choose from ran
