This article discusses definitional and methodological problems which
have marked the forty-year history of the Allport-Pettigrew contact hy
pothesis and reports on a study of biracial private neighborhoods at t
wo points in time, including tests of all four enhancing conditions of
the hypothesis. Findings indicate that though interracial visiting an
d prejudice are inversely related, more strongly for whites than for b
lacks, support for the hypothesized qualifying conditions is stronger
for blacks. Duration in the contact situation and age of the responden
t are examined as tests of differential selection and as possible expl
anations for anomalous findings. New directions, guided by recent mode
ls and by reformulations of traditional frameworks, are suggested.
