Introduction to the special issue on the self and social identity.

This article describes the special issue of the Journal of Personality and Social Psychology (JPSP), which is the result of a joint undertaking by the three sections of JPSP. This makes it different from previous special sections or issues of the journal in that rather than relying on the generous services of a guest editor, the same editorial team that handles the regular journal issues has originated this special issue, as well, thus conveying a sense of "business as usual." Our major reason for the present initiative was to highlight the essential unity of personality and social psychology as a field of science. The topic choice for the present special issue was dictated by its relevance and interest to the field of personality and social psychology as a whole, across its various partitions and subdivisions. The articles in the special issue amply reflect the naturalness with which the self and social identity theme transcends the boundaries of JPSP sections.
