The socialization (So) scale of the California Psychological Inventory
is based partly on a role-taking or perspective-taking theory of soci
al deviance and partly on the pragmatics of differentiating between mo
re socialized and less socialized individuals. The theory, history, an
d current applications of the scale are reviewed, relationships to oth
er scales and measures are examined, and the validity of the scale in
arraying 69 male and 40 female samples along a putative continuum of s
ocialization is evaluated. Finally, from these findings and from analy
ses of observers' adjectival and Q-sort descriptions significantly rel
ated to the scale, an interpretive psychology of the measure is propou
nded.
