How provocation by a single out-group member exacerbates perceptions o
f out-group dissimilarity was examined. Male American college students
provoked by a Latvian college student not only perceived him as dissi
milar from their own group of American college students but also perce
ived other Latvians (but not Senegalans, an irrelevant out-group) as d
issimilar from American college students. Drawing negative inferences
about the Latvian provocateur was correlated with perceiving other Lat
vians as dissimilar.
