Turner(1976) proposed the hypothesis that people who believe their real selves are institutuional selves tend to believe their selves are revealed when they adhere to high standards and when they are in full control of their behaviors.
The institutional self is based on the pursuit of society's goals and in the acceptance of group obligations.
People who believe their real selves are impulsive tend to feel their real selves are revealed in spontaneous behavior that occurs when one's inhibitions are lowered.
The implusive self is based on the pursuit of satisafaciton of implulses that are not a part of society's goals.
On the other hand Rubenstein & Shaver(1982) , from a social needs perspectives, proposed that loneliness comes in two forms, emotional isolation and social isolation, and each is due to an absence or deficiency of two basic categories of kinds of provisions that one can be labelled "psychological intimacy" and the other, "integrated involvement".
Based on these two different propositions, we hypothesized that for building up our social identity, and have a feeling of the integrated involvement, we have to take some important roles on the processes of pursuit of social goals, but in Japan, recently people tend to pursit of satisfaction of implulses like American people.
This hypothesis means that people are apt to alienate their social identity and many recent social phenomena like the concern for blood group polymorphisms of ABO system to grasp personlity can be understand as one of the symptons of alienation of social identity.
Our survy research on 184 females aged 30-64 to test above hypohtesis showed this prediction have certain validity.
