Racial integration : a social intervention on a South African university campus
Published 2016“…Gordon Allport's contact theory has given rise to the widely accepted proposition that contact improves intergroup attitudes, with stronger effects in settings that reflect optimal conditions of contact. Investigators have long been interested in the effects of contact in South Africa where, until twenty years ago, intergroup contact had been formally restricted. …”
