The shape of self-extension: Mapping the extended self with multidimensional scaling

ABSTRACT:

This exploratory study examined the three domains of self-extension proposed by William James' Constituents of Self—the psychological, social, and material domains. A novel analytic method, Multidimensional Scaling (MDS-T), was used to represent the structure of James' self-extension domains in geometric space for a large sample of American adults (N = 1181). Differences in the structure of self-extension by gender, race, age, and emotional health were also explored. Results suggested that the extended self, as conceptualized by James, has a clear and robust structure. Each of James' self-extension domains were distinctly represented in geometric space; yet, findings suggest a slight refinement of the self-extension subdomain groupings. Additionally, potential links between the structure of self-extension, age and emotional health were also observed.

Findings from this study should be viewed as heuristic, lending empirical support to long-standing theory on the configuration of the self, characterized through extension.
