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.

Famous quotes containing the words social and/or theory:

    If twins are believed to be less intelligent as a class than single-born children, it is not surprising that many times they are also seen as ripe for social and academic problems in school. No one knows the extent to which these kind of attitudes affect the behavior of multiples in school, and virtually nothing is known from a research point of view about social behavior of twins over the age of six or seven, because this hasn’t been studied either.
    Pamela Patrick Novotny (20th century)

    Thus the theory of description matters most.
    It is the theory of the word for those
    For whom the word is the making of the world,
    The buzzing world and lisping firmament.
    Wallace Stevens (1879–1955)
